Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Aspirin, as a first-line drug for the treatment of cardiovascular diseases, currently has high clinical usage. However, reports of aspirin-induced gastric mucosal injury are increasing. Xiaojianzhong decoction (XJZD), a classic traditional Chinese medicine formula, has been shown to alleviate gastric mucosal injury, although its potential mechanism of action requires further study. AIM OF THE STUDY This study aimed to explore the effect and mechanism of XJZD in preventing aspirin-induced gastric mucosal injury. MATERIALS AND METHODS Aspirin was used to induce damage in the morning, while XJZD was applied as an intervention in the afternoon. The compounds in the XJZD were analyzed by means of both high-performance liquid chromatography and ultra-performance liquid chromatography-tandem mass spectrometry. The overall condition of the aspirin-related gastric mucosal injury was evaluated. The expressions of inflammatory factors and tight-junction-related proteins and apoptosis were observed via immunohistochemistry and immunofluorescence. The expression levels of the apoptosis-related proteins were detected using Western blot. Transcriptomics was used to perform the integrative analysis of gastric tissues, which was then validated. Molecular dynamics was used to explore the interaction of key compounds within the XJZD with relevant targets. Finally, non-targeted metabolomics was used to observe any metabolic changes and construct a network between the differentially expressed genes and the differential metabolites to elucidate their potential relationship. RESULTS XJZD can alleviate inflammation response, maintain the gastric mucosal barrier's integrity, reduce apoptosis and necroptosis levels, and promote the proliferation and repair of gastric mucosal tissues. Its mechanism of action may be related to the regulation of TNF-α signaling. Furthermore, molecular docking showed that the cinnamaldehyde within XJZD played an important role in its effects. In addition, XJZD can correct metabolic disorders, mainly regulating amino acid metabolism pathways. Moreover, six differential genes (Cyp1a2, Cyp1a1, Pla2g4c, etc.) were determined to alleviate both gastric mucosal injury and inflammation by regulating arachidonic acid metabolism, Tryptophan metabolism, etc. CONCLUSIONS: This study is the first to report that XJZD can inhibit necroptosis and gastric mucosal injury induced by aspirin, thereby revealing the complex mechanism of XJZD in relation to alleviating gastric mucosal injury from multiple levels and perspectives.

Abstract
CONTEXT Xiaojianzhong decoction (XJZD), classically prescribed in Chinese medicine, has protective and healing effects on gastric mucosal injury. However, the exact mechanism behind this effect remains unclear. OBJECTIVE To investigate the effect of XJZD on gastric mucosal injury and explore its underlying mechanisms. MATERIALS AND METHODS C57BL/6 mice were randomized into six groups (n = 10): the control group receiving sterile water, the model (aspirin 300 mg/kg), the XJZD high-dose (12 g/kg), XJZD medium-dose (6 g/kg), XJZD low-dose (3 g/kg) and omeprazole (20 mg/kg) groups, by gavage daily for 14 days. The area of gastric mucosal injury, mucosal injury index and degree of histopathological damage were analysed. Gastric mucosal epithelial cell apoptosis was detected. Epithelial cell autophagy was observed. The expression levels of tight junction proteins and proteins related to apoptosis, autophagy and the pentose phosphate pathway were analysed. RESULTS The results showed that after treatment with XJZD (12, 6 and 3 g/kg), the mucosal injury area was reduced (83.4%, 22.6% and 11.3%), the expression level of ZO-1 and occludin was up-regulated, the apoptosis rate of epithelial cells was reduced (40.8%, 25.4% and 8.7%), the expression of autophagy-related proteins LC3 and Beclin1 was decreased and the expression of p62 was increased, the PI3K/AKT/mTOR/ULK1(ser757) signalling pathway was activated, and the AMPK/ULK1(ser317) signalling pathway was inhibited. In addition, XJZD can antagonize the imbalance of redox homeostasis caused by aspirin and protect the gastric mucosa. DISCUSSION AND CONCLUSIONS XJZD protects against aspirin-induced gastric mucosal injury, implying it to be a potential therapeutic agent.

Abstract
As a widely used drug in clinical practice, aspirin has a large number of residual drugs and metabolites discharged into the environment during the pharmaceutical process or after taking the drug. Aspirin content and its metabolite, salicylic acid, have been reported and detected in several river water samples and municipal wastewaters. However, little is known about the toxicity mechanisms of this drug in aquatic invertebrates. In this study, we examine the toxic effect and investigate the toxicity mechanism of aspirin in planarian, which own the excellent regeneration and sensitive toxicity detection ability. Planarian is treated with 0.7 mM aspirin for 6 h, 48 h, 3 d and 5 d, and the mRNA and protein expression levels of the stem cells markers, in parallel with the target genes of the signaling pathway are analyzed by RT-qPCR, whole-mount immunofluorescence, and Western blot. The results show that aspirin strongly inhibits stem cell proliferation and causes retarded blastemas growth in planarians. Furthermore, the mRNA and protein expression levels of stem cells markers and the target genes dramatically decrease after the aspirin treatment. Meanwhile, the expression level of apoptotic cells also shows a downward trend. Their significant and coincident downregulations after the aspirin treatment suggest that aspirin regulates planarian regeneration via STAT3/SOX2/OCT4 signaling pathway. Our work reveals the toxicological effect and the mechanism of aspirin to the planarian, and provides basic data for therapeutic applications of aspirin in regeneration and warns about the ecological damage of aspirin abuse.

Abstract
Cutaneous eruptions caused by the combination of Chinese and Western medicine have attracted widespread attention; however, the underlying mechanism remains unclear. This study aimed to evaluate the potential mechanism of cutaneous eruptions in vivo and in vitro using the combination of Shuanghuanglian injection powder (SHL) and aspirin (ASA) as an example. ASA and SHL co-administration induced inflammatory responses in HaCat cells, as evidenced by marked increases in the expression of IL-4 and TNF-α, and the level of apoptosis. Additionally, histopathological investigation of mice skin tissues showed local inflammatory cell infiltration. Western boltting was used to detect the effects of ASA on desmoglein-1 (DSG1) expression; we found that DSG1 expression was down-regulated in vivo and in vitro. Finally, the key components of SHL were administered to HaCat cells with down-regulated DSG1; it was seen that neochlorogenic acid and rutin have a significant effect on HaCat cell apoptosis. These results demonstrate that DSG1 deficiency is a potential cause of cutaneous eruptions caused by the combination of SHL and ASA, and neochlorogenic acid and rutin are the main allergenic components. This study provides a new research strategy for the safety evaluation of integrated traditional Chinese and Western medicine.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The incidence of gastric mucosa lesions in the adult population has increased mainly due to the continued use of nonsteroidal anti-inflammatory drugs (NSAIDs). The cashew (Anacardium occidentale L.) is a tropical tree, cultivated in several countries, whose barks, leaves and pseudofruit (cashew apple) are popularly used in traditional medicine for the treatment of many diseases, including gastric ulcer. AIM Our study evaluated the potential gastroprotective effect of the carotenoid and anacardic acids-enriched aqueous extract (CAE), prepared from cashew apple pomace, in the dose-repeated acetylsalicylic acid (ASA)-induced gastric lesions model in rats. MATERIAL AND METHODS After randomly distribution into five group (G1 - G5, n = 8 animals/group), male Wistar rats were daily treated with ASA solution (200 mg/kg, 5 ml/kg, G2 - G5) or potable water (Satellite group, G1) during 14 days. From 8th to 14th experimental day, rats in G3 - G5 groups were orally treated with CAE (50, 100 and 500 mg/kg, 5 ml/kg, respectively). Body weight was measured on 0, 7th and 14th day. On the 14th experimental day, all surviving animals were euthanized for macroscopic evaluation of the inner organs and stomach removal. After weighting, each stomach was properly prepared for biochemical analysis [myeloperoxidase activity (MPO), reduced glutathione analysis (GSH), IL-1β, CXCL2/MIP-2, TNF-α and IL-10 levels]. RESULTS At the most efficient dose (100 mg/kg, p.o.), CAE-treated animals showed a slight improvement in the macroscopic aspect of gastric mucosa associated with significant (p < 0.05) reduced levels of IL-1β, CXCL2/MIP-2, and MPO activity besides increased levels of GSH (partially), and IL-10 in stomach tissues. CONCLUSIONS The present study demonstrated that the carotenoid and anacardic acids-enriched extract obtained from cashew apple pomace is a promising raw material for the development of herbal medicine and/or functional food supplements for the adjuvant treatment of NSAIDs-induced gastric ulcers.

Abstract
Here, we established a high-throughput in vitro assay system to predict reactive metabolite (RM) formation. First, we performed the glutathione (GSH) consumption assay to monitor GSH levels as an index of RM formation potential using HepaRG cells pretreated with 500 μM D,L-buthionine-(S,R)-sulfoximine (BSO) and then treated with ticlopidine and diclofenac. Both drugs, under GSH-reduced conditions, significantly decreased relative cellular GSH content by 70% and 34%, respectively, compared with that in cells not pretreated with BSO. Next, we examined the correlation between GSH consumption and covalent binding assays; the results showed good correlation (correlation coefficient = 0.818). We then optimized the test compound concentration for evaluating RM formation potential using 76 validation compound sets, and the highest sensitivity (53%) was observed at 100 μM. Finally, using HepG2 cells, PXB-cells, and human primary hepatocytes, we examined the cell types suitable for evaluating RM formation potential. The expression of CYP3A4 was highest in HepaRG cells, suggesting the highest sensitivity (56.4%) of the GSH consumption assay. Moreover, a co-culture model of PXB-cells and HepaRG cells showed high sensitivity (72.7%) with sufficient specificity (85.7%). Thus, the GSH consumption assay can be used to effectively evaluate RM formation potential in the early stages of drug discovery.

Abstract
Aspirin is one of the most commonly prescribed medications. Evidence shows that it can even treat and prevent intestinal tumors. However, it has also caused a great deal of controversy due to its intestinal side effects. We therefore explored whether aspirin was beneficial or harmful to the intestines. We used aspirin continuously interfered with C57BL/6 J mice for 48 weeks, examining their intestinal tissues at 13, 26 and 48 weeks to determine the drug's effect on the intestines. In addition, we used flow cytometry (FCM) used to detect T cells and expression of T-cell immunoreceptor with immunoglobulin (Ig)- and tyrosine-based inhibitory motif (ITIM) domain (TIGIT) on their surfaces to determine aspirin's immunomodulatory effects. The results showed that long-term aspirin intervention could reverse damage to the intestines, an effect related to the drug's significant inhibitory effect on TIGIT. The change in TIGIT level could regulate T-cell subsets, so that counts of Cluster of Differentiation 4 (CD4)+/chemokine (C-X3-C motif) receptor 3 (CXCR3)+ T-helper 1 (Th1) cells and CD4+/interleukin-4 (IL-4)+ Th2 cells increased, while those of CD4+/C-C chemokine receptor type 6 (CCR6)+ Th17 cells and CD4+/CD25+ regulatory T cells (Tregs) decreased. In summary, we demonstrated that long-term aspirin intervention could inhibit TIGIT, regulating T cells to reverse damage to the intestines. Furthermore, aspirin is a potential therapy for diseases related to an increase in TIGIT.

Abstract
BACKGROUND Aspirin is one of the popular, economical, easily accessible and commonly used drugs all over the world. Injudicious use of this over-the-counter available drug is a common cause of nephrotoxicity. The aim of the present study is to assess the protective effects of Nigella Sativa (NS) on the histology of kidneys against aspirin-induced toxicity. It was an experimental study that included comparative analysis of control and experimental groups, conducted in the department of Anatomy, University of Health Sciences, Lahore, from October 2016 to December 2016. METHODS The study included thirty-two female albino rats which were equally distributed into 4 groups. Group A was run as control and given single oral dose of 1% methyl-cellulose (10mg/100gm body weight of rat). Group B and C were treated with a single oral dose of aspirin (1000mg/kg body weight) dissolved in 1% methyl-cellulose (10mg/100gm body weight). Group C animals were left untreated for 7 days. Group D was pre-treated on day 1 with oral dose of Nigella Sativa (NS) extract (250mg/kg body weight) followed one hour later by a single oral dose of aspirin (1000mg/kg body weight), subsequently NS extract was administered till day 7. Rats of group B were euthanized and dissected on 2nd day of experiment while those of groups A, C and D on 8th day. Kidneys were dissected out, weighed and fixed in 10% formalin. 5μm thick sections were yielded after tissue processing and stained with haematoxylin, eosin (H&E staining) and periodic acid Schiff's reagent (PAS staining). Histological parameters of distal convoluted tubules (DCT) were observed. RESULTS All histological parameters were normal in group A. Group B showed marked increase in epithelial necrosis, intraluminal protein casts and broken basement membranes of distal convoluted tubules. Group C showed no self-recovery. Statistically significant improvement was observed in the histology of distal convoluted tubules with treatment of Nigella Sativa extract in aspirin-ingested rats in group D. CONCLUSIONS Nigella Sativa extract has shown protective effects on kidneys against aspirin-induced damage as shown by improvement in the histological parameters of distal convoluted tubules.

Abstract
Vitellogenin (VTG), a well-established biomarker for the diagnosis of endocrine activity in fish, is used in multiple OECD test guidelines (TG) to identify activities of chemicals on hormonal pathways. However, the synthesis of VTG may not only be modified by typical endocrine-related pathways, but also through non-endocrine-mediated processes. In particular, hepatotoxicity, i.e. toxicant-induced impairment of liver structure and function, might influence VTG as a biomarker, since VTG is synthesized in hepatocytes. An intimate understanding of the interplay between endocrine-related and non-endocrine-related pathways influencing VTG production is crucial for the avoidance of erroneous diagnoses in hazard assessment for regulatory purposes of chemical compounds. In order to investigate whether hepatotoxicity may interfere with hepatic VTG synthesis, adult zebrafish (Danio rerio) were exposed to three well-known hepatotoxicants, acetaminophen, isoniazid and acetylsalicylic acid, according to OECD TG 230. Various hepatotoxicity- and endocrine system-related endpoints were recorded: mRNA expression of selected endocrine- and hepatotoxicity-related marker genes in the liver; VTG levels in head/tail homogenates; and liver histopathology. All three test compounds induced significant, but mild single cell necrosis of hepatocytes and transcriptional changes of hepatotoxicity-related marker genes, thus confirming hepatotoxic effects. A positive correlation between hepatotoxicity and reduced hepatic VTG synthesis was not observed, with the single exception of a weak increase in female zebrafish exposed to APAP. This suggests that - in studies conducted according to OECD TG 229 or 230 - it is unlikely that hepatotoxic chemicals will interfere with the hepatic capacity for VTG synthesis.

Abstract
Pharmaceutical drugs in the wild may pose significant risks to non-target exposed organisms. This situation is even more troublesome for coastal marine or estuarine environments, located in the vicinity of large human conglomerates, for which the putative number of pollutants is extremely high, and the regime by which wild organisms are exposed is continuous. In addition, the number of studies addressing this issue is still scarce, despite evidences that show the potential contamination profiles and adverse biological effects in organisms from such areas. In this study, the ecotoxicity of common pharmaceutical drugs (namely paracetamol and acetylsalicylic acid) was assessed, by studying the susceptibility of the mussel species Mytilus spp to oxidative stress after being exposed for 96 h to increasing but ecologically relevant concentrations of the two mentioned pharmaceuticals (paracetamol: 0, 0.5, 5, 50, and 500 μg/L; acetylsalicylic acid: 0, 0.1, 1, 10, and 100 μg/L). The oxidative status in exposed organisms was analyzed by measuring oxidative stress biomarkers, namely catalase (CAT), glutathione-S-transferases (GSTs), and lipoperoxidation (LPO) levels, whose alteration was indicative of chemical exposure, in both digestive gland and gills of the organisms. In addition, the food uptake and the nutritional reserve status of exposed organisms were also assessed, by measuring the consumption of ingested food, and levels of tissue reserves of glycogen in gills and digestive gland. No significant alterations were observed in the assessed oxidative stress parameters so it was possible to hypothesize that the studied drugs may have probably exerted a limited alteration of antioxidant defenses and damage, which was reverted by the activation of defensive adaptive mechanisms. This set of data evidenced that the pro-oxidative metabolism that was already described for both drugs in other animal models, was not fully established in the exposed mussels. On the contrary, glycogen reserves were substantially changed after exposure to both toxicants, being possible to observe opposite responses caused by both drugs. Food uptake was not altered following exposure to the drugs. Further evaluations are thus required to conclude about both drugs ecotoxicity and other parameters, namely seasonality, which should be considered when performing ecotoxicology tests, especially with the selected species.

Abstract
Over time, the consumption of pharmaceutical drugs has highly augmented, directly contributing for an increase of the discharges of these substances into sewage water due to excretion, and their direct release to the environment, with or without adequate treatment. Considering that part of the sewage water is dumped into rivers and seas, this is the major source of contamination of the aquatic environment. Paracetamol and acetylsalicylic acid are among the most worldwide consumed pharmaceutical drugs, frequently found in wastewater discharges and consequently in the aquatic environment in considerable amounts, posing ecotoxicity concerns especially towards aquatic non-target species. Thus, it is important to study the ecotoxicological implications that these drugs might pose to organisms from aquatic environments. The objective of this study was to assess the toxic effects of these two compounds on key biochemical features (antioxidant defenses and damage, metabolism, and cholinergic neurotoxicity) of the marine snail species Gibbula umbilicalis after an acute (96 h) exposure, simulating pulses of contamination. In order to understand the effects that those drugs have on this species, the biochemical biomarkers analyzed were the activities of catalase (CAT), glutathione-S-transferases (GSTs), cholinesterases (ChEs), and the levels of lipid peroxidation (TBARS). After acute exposure to paracetamol, catalase activity decreased significantly in organisms exposed to both highest concentrations; no significant alterations were observed for glutathione-S-transferases activity; TBARS concentration decreased significantly in organisms exposed to the intermediate and both highest concentrations, and cholinesterase activity increased significantly in animals exposed to the lowest concentration. However, after acute exposure to acetylsalicylic acid, catalase activity increased significantly; no significant alterations were observed for glutathione-S-transferases activity, and TBARS concentrations and cholinesterase activity increased. This set of data shows that G. umbilicalis is highly responsive to the presence of the tested drugs, and may thus be a promising species to serve as test organism in future marine ecotoxicological testing. The adoption of this species may broaden the offer of highly ecologically representative test organisms to be included in biomonitoring projects of the coastal and marine environment. Furthermore, it is possible to suggest that both drugs may pose significant deleterious effects of pro-oxidative origin to the physiology of the selected species, with potential adverse ecological consequences, even after short periods of exposure. The absence of neurotoxicity showed that despite being able to trigger antioxidant mechanisms, both drugs did not affect neurotransmission.

Abstract
Coastal areas are continually impacted by anthropic activities because they shelter large urban conglomerates. Urban effluents directly or indirectly end up reaching the marine environment, releasing a large number of pollutants which include the so-called contaminants of emerging concern (CECs), since the conventional treatment plants are not effective in removing these compounds from the effluents. These substances include hormones, pharmaceuticals and personal care products, nanoparticles, biocides, among others. The aim of this study was to evaluate the toxicity of the 17α-ethinylestradiol (EE2), acetylsalicylic acid (ASA), and bisphenol-A (BPA) to two marine crustaceans and one echinoderm, evaluating the following parameters: survival (Artemia sp. and Mysidopsis juniae), embryo-larval development (Echinometra lucunter). The LC50 values calculated in the acute toxicity tests showed that the compounds were more toxic to M. juniae than to the Artemia sp. Among the three contaminants, EE2 was the most toxic (LC50-48h = 18.4 ± 2.7 mg L-1 to Artemia sp.; LC50-96h = 0.36 ± 0.07 mg L-1 to M. juniae). The three tested compounds affected significantly the embryonic development of the sea urchin in all tested concentrations, including ecologically relevant concentrations, indicating the potential risk that these contaminants may present to the marine biota.

Abstract
Mild analgesics such as acetylsalicylic acid (ASA) and acetaminophen (APAP) exert their pain-relieving effect in humans by inhibition of prostaglandin synthesis. Prostaglandins play key roles in developmental and reproductive processes in vertebrates, and in recent years, it has been suggested that weak analgesics might also act as endocrine disrupters. In a set of experiments we investigated if ASA and APAP affect well-established endocrine endpoints in zebrafish (Danio rerio), which is a commonly used model organism in the investigation of endocrine disrupting chemicals. Zebrafish were exposed to APAP (0.22, 2.3, and 30mgL-1) or ASA (0.2, 0.5, 1.7, and 8.2mgL-1) from hatch to sexual maturity in a test design resembling the OECD Fish Sexual Development Test. No effects on sex ratio and vitellogenin levels were observed. Adult zebrafish were exposed to high concentrations (mgL-1) of ASA or APAP for eight or 14days. ASA reduced the levels of prostaglandin E2, but had no effect on the concentration of 11-ketotestosterone and vitellogenin. Overall, ASA decrease prostaglandin E2 concentrations, but well-established endpoints for endocrine disruption in zebrafish are generally not affected by aquatic exposure neither during development nor adulthood. According to the WHO/IPCS definition of an endocrine disrupter, the present results do not define APAP and ASA as endocrine disrupters.

Abstract
CONTEXT Essential oils from Pinus species have been reported to have various therapeutic properties. OBJECTIVE This study was undertaken to identify the chemical composition and cytoprotective effects of the essential oil of Pinus halepensis L. against aspirin-induced damage in cells in vitro. MATERIAL AND METHODS The cytoprotection of the oil against toxicity of aspirin on the small intestine epithelial cells IEC-6 was tested. RESULTS The obtained results have shown that 35 different compounds were identified. Aspirin induced a decrease in cell viability, and exhibited significant damage to their morphology and an increase in superoxide dismutase (SOD) and catalase (CAT) activities. However, the co-treatment of aspirin with the essential oil of Pinus induced a significant increase in cell viability and a decrease in SOD and CAT activities. CONCLUSION Overall, these finding suggest that the essential oil of Pinus halepensis L. has potent cytoprotective effect against aspirin-induced toxicity in IEC-6 cells.

Abstract
The aim of the present study was to define changes in the expression of somatostatin (SOM) in the sympathetic perikarya innervating the porcine stomach prepyloric area during acetylsalicylic-acid-induced gastritis (ASA) and experimentally induced hyperacidity (HCL) and following partial stomach resection (RES). On day 1, the stomachs were injected with neuronal retrograde tracer Fast Blue (FB). Animals in the ASA group were given acetylsalicylic acid orally for 21 days. On the 22nd day after FB injection, partial stomach resection was performed in RES animals. On day 23, HCL animals were intragastrically given 5 ml/kg of body weight of a 0.25 M aqueous solution of hydrochloric acid. On day 28, all pigs were euthanized. Then, 14-μm thick cryostat sections of the coeliac-superior mesenteric ganglion (CSMG) complexes were processed for routine double-labelling immunofluorescence. All pathological conditions studied resulted in upregulation of SOM-like (SOM-LI) immunoreactivity (from 14.97 ± 1.57% in control group to 33.72 ± 4.39% in the ASA group, to 39.02 ± 3.65% in the RES group, and to 29.63 ± 0.85% in the HCL group). The present studies showed that altered expression of SOM occurs in sympathetic neurons supplying the prepyloric area of the porcine stomach during adaptation to various pathological insults.

Abstract
Aspirin, one of the widely used nonsteroidal anti-inflammatory drugs, is the most highly consumed pharmaceutical product in the world. However, it has several side effects in cells. This study was designed to investigate the antioxidative activity and cytoprotective effects of essential oil of Citrus limon (EOC) extracted from leaves against aspirin-induced damages in the rat small intestine epithelial cells (IEC-6). Biochemical indicators were used to assess cytotoxicity and oxidative damages caused by aspirin treatment on IEC-6. Our results showed that the chemical characterization of EOC identified 25 compounds representing 98.19% of the total oil. The major compounds from this oil were z-citral (53.21%), neryl acetate (13.06%), geranyl acetate (10.33%), and limonene (4.23%). Aspirin induced a decrease in cell viability as well as an increase in superoxide dismutase (SOD) and catalase (CAT) activities. Contrariwise, the co-exposure of cells to aspirin and EOC alleviated every above syndrome by an increase in cell survival and decrease in SOD and CAT activities. In conclusion, the essential oil of C. limon has a potent cytoprotective effect against aspirin-induced toxicity in IEC-6 cells.

We used a safe stable gastric pentadecapeptide BPC 157 (GEPPPGKPADDAGLV, MW 1419), LD1 not achieved, since successful in inflammatory bowel disease trials, and counteracts esophagitis, sphincters failure, gastrointestinal ulcer and skin ulcer, external and internal fistulas in rats, and particularly counteracts all NSAIDs-lesions. We assessed lower esophageal sphincter and pyloric sphincter pressure (cmH2O) in rats treated with various NSAIDs regimens, at corresponding time points, known to produce stomach, small intestine lesions, hepatotoxicity and encephalopathy. Assessment was after diclofenac (12.5 mg/kg, 40 mg/kg intraperitoneal challenge), ibuprofen (400 mg/day/kg intraperitoneally for 4 weeks), paracetamol (5.0 g/kg intraperitoneal challenge), aspirin (400 mg/kg intraperitoneally or intragastrically), celecoxib (0.5 mg/kg, 1.0 mg/kg intraperitoneally). BPC 157 (10 μg/kg, 10 ng/kg) was given immediately after NSAIDs (intraperitoneally or intragastrically) or given in drinking water. Regularly, in all control NSAIDs fall of pressure occurred in both sphincters rapidly and then persisted. By contrast, in all NSAIDs-rats that received BPC 157, initial fall of pressure was minimized and pressure values restored to normal values. All tested NSAIDs decrease pressure in both sphincters, whilst BPC 157 counteracts their effects and restored both sphincters function.

Abstract
Nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used therapeutic agents; however, their pharmacological actions raise concerns about potential risks to the reproductive health of aquatic vertebrates. In the present study, a medaka ovulation assay was applied as an in vitro model to evaluate NSAID-induced antiovulatory activity. We first tested five NSAIDs, including diclofenac sodium (DCF), ketoprofen (KP), salicylic acid (SA), mefenamic acid (MA), and acetylsalicylic acid (ASA) for their antiovulatory activities toward the follicles isolated from the ovaries of spawning females. Of all the chemicals tested, DCF had the highest antiovulatory activity, with the concentration that caused 50% inhibition (IC50) (101 µM). MA was the second most potent inhibitor following DCF, but KP, SA, or ASA had little inhibitory effect on the ovulation of the follicles. The in vitro antiovulatory activity of five NSAIDs showed good correlation with data published on the inhibitory activity on human COX-2. Second, we selected DCF and SA as the most and least potent NSAIDs, respectively, and examined the effects on reproduction of intact fish in order to evaluate whether the ovulation assay was a reasonable predictor of potential reproductive effects in fish. Females exposed to DCF showed a concentration-dependent decrease in the number of spawned eggs and an increment in the gonadosomatic index (GSI), possibly due to an anovulation in the females. In contrast, neither fecundity nor the GSI of females decreased at up to 20 mg/L of SA, at which acute lethality to medaka was induced. In conclusion, the medaka ovulation assay reflected the potency of NSAID-induced antiovulatory activity and may thus serve as an in vitro model for the prediction of NSAID-induced reproductive toxicity. © 2015 Wiley Periodicals, Inc.

Abstract
A 16-year-old man was transferred to our emergency department seven hours after ingesting 486 aspirin tablets. His blood salicylate level was 83.7 mg/dL. He was treated with fluid resuscitation and sodium bicarbonate infusion, and his condition gradually improved, with a decline in the blood salicylate level. However, eight days after admission, he again reported nausea, a venous blood gas revealed metabolic acidosis with a normal anion gap. The blood salicylate level was undetectable, and a urinalysis showed glycosuria, proteinuria and elevated beta-2 microglobulin and n-acetyl glucosamine levels, with a normal urinary pH despite the acidosis. We diagnosed him with relapse of metabolic acidosis caused by renal tubular acidosis.

Abstract
BACKGROUND The effect of rebamipide on repairing intestinal mucosal damage induced by nonsteroidal anti-inflammatory drugs and its mechanism remain unclear. In this study, we sought to explore the mechanism whereby rebamipide could promote the regeneration of aspirin-induced intestinal mucosal damage. METHODS BALB/c mice were administered aspirin (200 mg/kg/d) for 5 days to induce acute small intestinal injury (SII). Subsequently, SII mice were treated with rebamipide (320 mg/kg/d) for 5 days. The structure of intestinal barrier was observed with transmission electron microscope, and Zo-1 and occludin expressions were detected. The proliferative index was indicated by the percentage of proliferating cell nuclear antigen positive cells. The prostaglandin E2 (PGE2) levels in the small intestine tissues were measured by an enzyme immunoassay. The mRNA and protein expression levels of cyclooxygenase (COX) and β-catenin signal were detected in the small intestine using quantitative PCR and Western blot, respectively. RESULTS COX expression was significantly down-regulated in aspirin induced SII (P < 0.05). In SII mice treated with rebamipide, histopathological findings of aspirin-induced intestinal inflammation were significantly milder and tight junctions between intestinal epithelial cells were improved significantly. The proliferative index increased after rebamipide treatment when compared with that in the control mice. The expressions of COX-2, β-catenin, and c-myc and the PGE2 concentrations in small intestinal tissues were significantly increased in mice with rebamipide treatments (P < 0.05). CONCLUSION Rebamipide administration in aspirin-induced SII mice could improve the intestinal barrier structure and promote the regeneration of small intestinal epithelial injury through up-regulating COX-2 expression and the accumulation of β-catenin.

Abstract
BACKGROUND Cyclooxygenase-2 selective inhibitors have been developed to alleviate pain and inflammation; however, the use of a selective cyclooxygenase-2 inhibitor is associated with mild edema, hypertension, and cardiovascular risk. AIM To evaluate, in an experimental model in normotensive rats, the effect of treatment with parecoxib in comparison with diclofenac and aspirin and L-NAME, a non-selective nitric oxide synthetase, on mean arterial blood pressure, and cyclooxygenase-1 and -2 messenger RNA and protein expression in aortic tissue. METHODS Rats were treated for seven days with parecoxib (10 mg/kg/day), diclofenac (3.2 mg/kg/day), aspirin (10 mg/kg/day), or L-NAME (10 mg/kg/day). Mean arterial blood pressure was evaluated in rat tail; cyclooxygenase-1 and -2 were evaluated by reverse transcription-polymerase chain reaction and Western blot analysis in aortic tissue. RESULTS Parecoxib and L-NAME, but not aspirin and diclofenac, increased mean arterial blood pressure by about 50% (p < 0.05) without changes in cardiac frequency. Messenger RNA cyclooxygenase-1 expression in aortic tissue was not modified with any drug (p < 0.05). L-NAME and parecoxib treatment decreased messenger RNA cyclooxygenase-2 and cyclooxygenase-2 (p < 0.05). While cyclooxygenase-1 protein decreased with the three drugs tested but not with L-NAME (p < 0.05), the cyclooxygenase-2 protein decreased only with aspirin and parecoxib (p < 0.05). CONCLUSION Parecoxib increases the blood pressure of normotensive rats by the suppression of COX-2 gene expression, which apparently induced cardiovascular control.

Abstract
There are many available drugs for treating gastric ulcer, but they have various side effects. Ginger is a folk, herbal medicine, which is used for treatment of various diseases including gastric ulcer. This study investigates the possible mechanism of the protective effect of ginger on aspirin induced gastric ulcer. Forty adult male albino rats were randomized into four groups (10 animal per each group) and orally received the followings once daily for 5 days: Group I: 3 ml of 1% carboxymethyl cellulose; Group II: ginger powder (200 mg/kg body weight) suspended in 3 mL of 1% carboxymethylcellulose; Group III: aspirin (400 mg/kg body weight) suspended in 3 ml of 1% carboxymethylcellulose in water. Group IV: ginger and 30 minutes later, received aspirin suspended in 1% carboxymethylcellulose, in similar doses as received in groups II and III. On day 6, rats were sacrificed. The animals were anesthetized and the stomach was removed for the macroscopic, histological (Haematoxylin & Eosin and Periodic Acid Shiff) and immunohistochemical investigations (Bax, inducible nitric oxide synthase and heat shock protein 70). Aspirin induced a significant increase of the macroscopic ulcer score, shed and disrupted epithelium, mucosal hemorrhage, submucosal edema and leukocyte infiltration, loss of the mucus of the mucosal surface significantly increased expression of apoptosis regulator Bax, inducible nitric oxide synthase (iNOS) and heat shock protein 70 (HSP70). Ginger ameliorated the histological changes by reducing Bax and iNOS and increasing HSP70 expressions.

Abstract
Toxicity in natural ecosystems is usually not due to exposure to a single substance, but is rather the result of exposure to mixtures of toxic substances. Knowing the effects of contaminants as a mixture compared to their effects in isolated form is therefore important. This study aimed to evaluate the oxidative stress induced by binary mixtures of diclofenac with paracetamol, ibuprofen, naproxen, and acetylsalicylic acid and by these nonsteroidal anti-inflammatory drugs (NSAIDs) in isolated form, using Hyalella azteca as a bioindicator. The median lethal concentration (LC50) and the lowest observed adverse effect level (LOAEL) of each NSAID were obtained. Amphipods were exposed for 72 h to the latter value in isolated form and as binary mixtures. The following biomarkers were evaluated: lipid peroxidation (LPX), protein carbonyl content (PCC), and activity of the antioxidant enzymes: superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx). Significant increases in LPX and PCC with respect to the control group (p ≤ 0.05) were induced by NSAIDs both in isolated form and as binary mixtures. Changes in SOD, CAT, and GPx activity likewise occurred with NSAIDs in isolated form and as binary mixtures. In conclusion, NSAIDs used in this study induce oxidative stress on H. azteca both in isolated form and as binary mixtures, and the interactions occurring between these pharmaceuticals are probably antagonistic in type.

Abstract
CONTEXT The leaf of Careya arborea Roxb. (Lecthidaceae) has been advocated in Ayurveda for the treatment of various disorders, including ulcers, healing of wounds and several skin diseases. OBJECTIVE The 70% ethanol (EtOH) extract of C. arborea leaves (CALE) was investigated for its gastroprotective effect in different gastric ulcer models. MATERIALS AND METHODS CALE (100, 200, and 400 mg/kg body weight) was administered orally, twice daily for 5 d, for preventing aspirin (ASP)-, EtOH-, pylorus ligation (PL)-, and cold restraint stress (CRS)-induced ulcer in rats. The status of the antioxidant enzymes in CRS-induced ulcers, H(+)K(+)ATPase activity, gastric wall mucous in EtOH-induced ulcer, and gastric secretion parameters were estimated in the PL-induced ulcer model. RESULTS CALE exhibited significant (p < 0.01) dose-dependent inhibition of ulcer index in ASP 12.90-51.61%, EtOH 11.97-40.35%, PL 28.63-63.92%, and CRS 38.30-66.37%, respectively. A significant (p < 0.001) decrease occurred in the level of H(+)K(+)ATPase, volume of gastric juice, and acid output. Simultaneously, the level of gastric wall mucus was increased significantly (p < 0.05). The antioxidant enzyme levels of LPO and SOD were decreased with concomitant increase in catalase activity in CRS-induced ulcers. High-performance thin-layer chromatography (HPTLC) showed the presence of quercetin, ellagic acid, and gallic acid (0.31%, 0.24%, and 0.71% w/w, respectively) in CALE. CONCLUSIONS Our results show that C. arborea possesses significant gastro-protective activity, probably due to its free radical scavenging activity, and validate the folklore claim.

Abstract
Acetylsalicylic acid is a nonsteroidal anti-inflammatory widely used due to its low cost and high effectiveness. This compound has been found in water bodies worldwide and is toxic to aquatic organisms; nevertheless its capacity to induce oxidative stress in bioindicators like Daphnia magna remains unknown. This study aimed to evaluate toxicity in D. magna induced by acetylsalicylic acid in water, using oxidative stress and DNA damage biomarkers. An acute toxicity test was conducted in order to determine the median lethal concentration (48-h LC50) and the concentrations to be used in the subsequent subacute toxicity test in which the following biomarkers were evaluated: lipid peroxidation, oxidized protein content, activity of the antioxidant enzymes superoxide dismutase, catalase, and glutathione peroxidase, and level of DNA damage. Lipid peroxidation level and oxidized protein content were significantly increased (p<0.05), and antioxidant enzymes significantly altered with respect to controls; while the DNA damage were significantly increased (p<0.05) too. In conclusion, acetylsalicylic acid induces oxidative stress and DNA damage in D. magna.

Abstract
Aspirin has been used for a long time as an analgesic and anti-pyretic drug. Limitations of its use, however, remain for the gastro-intestinal side effects and erosions. Although the role of aspirin on gastro-intestinal injury has been extensively studied, the molecular mechanisms underlying aspirin-induced liver and spleen pathophysiology are poorly defined. The present study has been conducted to investigate whether phyllanthus niruri protein (PNP) possesses any protective role against aspirin mediated liver and spleen tissue toxicity, and if so, what signaling pathways it utilizes to convey its protective action. Aspirin administration in mice enhanced serum marker (ALP) levels, reactive oxygen species (ROS) generation, reduced antioxidant power and altered oxidative stress related biochemical parameters in liver and spleen tissues. Moreover, we observed that aspirin intoxication activated both the extrinsic and intrinsic apoptotic pathways, as well as down regulated NF-κB activation and the phosphorylation of p38 and JNK MAPKs. Histological assessments and TUNEL assay also supported that aspirin induced tissue damages are apoptotic in nature. PNP treatment after aspirin exposure effectively neutralizes all these abnormalities via the activation of survival PI3k/Akt pathways. Combining all results suggest that PNP could be a potential protective agent to protect liver and spleen from the detrimental effects of aspirin.

Abstract
The introduced Australian brushtail possum is a major vertebrate pest in New Zealand, with impacts on conservation and agriculture being managed largely through poisoning operations. Cholecalciferol (vitamin D3) is registered for use in controlling possums and despite its many advantages it is expensive and relatively inhumane. Combination of a high proportion of aspirin with a low proportion of cholecalciferol was effective in killing high proportions of groups of acclimatised, caged possums: this is attributed to both an unexpectedly high toxicity of the type of cholecalciferol used, and a proposed synergistic mechanism between the two compounds. Death was caused by localised damage to heart ventricles by aspirin, and inhibition of tissue repair by both aspirin and cholecalciferol. The observed toxicosis had lower impact on the welfare of possums than either compound administered alone, particularly aspirin alone. Residue analyses of bait remains in the GI tract suggested a low risk of secondary poisoning by either compound. The combination of cholecalciferol and aspirin has the potential to meet key requirements of cost-effectiveness and humaneness in controlling possum populations, but the effect of the combination in non-target species has yet to be tested.

Abstract
We examined the effect of egualen, a stable azulene derivative, against gastric damage induced by ischemia/reperfusion (I/R), gastric bleeding induced by double antiplatelet therapy with aspirin (ASA) plus clopidogrel, and small intestinal damage generated by loxoprofen, and investigated the possible mechanisms involved in its protective action. Male C57BL/6 mice or SD rats were used under urethane anesthesia (gastric lesions) or in a conscious (intestinal lesions) state. I/R-induced gastric injury was produced in mice by clamping the celiac artery for 30 min, followed by reperfusion for 60 min. Gastric bleeding was induced in rats by luminal perfusion with 25 mM ASA+50 mM HCl for 2 hours in the presence of clopidogrel (30 mg/kg). To produce small intestinal lesions the rats were given loxoprofen (60 mg/kg) p.o. and killed 24 hours later. Egualen was given i.d. 60 min before I/R or ASA perfusion, while given p.o. twice 30 min before and 6 hours after loxoprofen. Egualen significantly prevented the I/R-induced gastric damage, and the effect was equivalent to that of seratrodast (TXA2 antagonist). This agent also significantly suppressed gastric bleeding induced by ASA plus clopidogrel, similar to PGE2. Likewise, egualen significantly prevented loxoprofen-induced damage in the small intestine, accompanied by an increase in the secretion of mucus and suppression of bacterial invasion as well as iNOS expression. These results suggest that egualen has a prophylactic effect against various lesions in the gastrointestinal mucosa, probably through its characteristic pharmacological properties, such as TXA2 antagonistic action, local mucosal protection, and stimulation of mucus secretion.

Abstract
OBJECTIVES The aim of this study was to investigate the effects of subchronic exposure of juvenile development stages of zebrafish (Danio rerio) to acetylsalicylic acid using selected oxidative stress biomarkers. DESIGN Toxicity test with acetylsalicylic acid was performed according to the OECD Guideline No. 215, fish D. rerio aged 30 days were used. The tested concentrations were 0.004, 0.4, 40, 120 and 250 mg.L-1, duration of the test was 28 days. Products of lipid peroxidation and antioxidant enzymes were determined as the markers of oxidative stress. RESULTS Significantly increased glutathione S-transferase activity was found in fish exposed to acetylsalicylic acid concentrations 40, 120 and 250 mg.L-1. The highest values of glutathione reductase activity were found in the groups exposed to acetylsalicylic acid concentrations 0.4, 40 and 120 mg.L-1. In the group exposed to acetylsalicylic acid concentrations 40 mg.L-1, catalase activity was significantly higher compared to the control group. Significantly higher glutathione peroxidase activity was found in the groups exposed to acetylsalicylic acid concentrations 0.004 and 120 mg.L-1. The concentrations of TBARS were lower in fish exposed to acetylsalicylic acid at all tested concentrations compared to control. CONCLUSION The subchronic exposure of zebrafish to acetylsalicylic acid causes an increase in activity of antioxidant and biotransformation enzymes and a decrease in lipid peroxidation.

Abstract
The effects of diclofenac sodium, diclofenac potassium, alminoprofen and aspirin on serum electrolytes (serum Na(+) and K(+)), urea and creatinine were compared in rabbits in acute and chronic phases of treatment. The data suggested that all the four drugs markedly increased the serum electrolytes, urea and creatinine levels in both post-treatment phases. In conclusion, present study does not present any advantage of diclofenac sodium over diclofenac potassium at electrolyte levels on short and long term treatment. Nevertheless, current data support the evidence of renal function impairment by all the four drug therapies used in the present study, which is generally caused by NSAIDS.

Abstract
BACKGROUND/AIM Gastro duodenal ulcer is a common disorder of the gastrointestinal tract. Several Indian medicinal plants have been traditionally and extensively used to prevent different diseases. In the present research studies, Bael fruit (Aegle marmelos (AM), family: Rutaceae) which are also called as Bilva in ancient Sanskrit was used as a herbal drug and its antioxidative role in aspirin- induced gastroduodenal ulceration in albino rat was evaluated using essential biochemical parameters. PATIENTS AND METHODS Mucosal thickness (MT), ulcer index (UI), different biochemical parameters, such as aspartate aminotransferase (AST), alanine aminotransferase (ALT), catalase (CAT), superoxide dismutase (SOD), reduced glutathione (GSH), and lipid peroxidation (LPO) were measured in all the groups, to study the possible involvement of antioxidants with gastroduodenal protection. RESULTS A significant decrease in MT, SOD and CAT activities and GSH level and a significant increase in UI, AST, ALT, and ALP activities and LPO level were observed in aspirin treated stomach and duodenum of albino rats. CONCLUSIONS Pretreatment with AM fruit pulp extract for 14 consecutive days showed the reverse effects of aspirin suggesting gastro-duodenal protective and anti- ulcerogenic properties of AM through its antioxidant mechanism.

Abstract
OBJECTIVES The aim of this study was to compare the acute toxicity of acetylsalicylic acid to embryonic and juvenile stages of aquarium fish - zebrafish (Danio rerio), oxidative stress parameters and detoxifying enzyme. METHODS Tests were performed according to OECD No. 203 (Fish, acute toxicity test) and OECD No. 212 (Fish, short-term toxicity test on embryo and sac-fry stages) methodology. RESULTS The results showed the mean acetylsalicylic acid LC50 value to be 567.7 mg/L in juvenile zebrafish. The acute toxicity of acetylsalicylic acid for zebrafish embryos was 274.6 mg/L. Statistically significantly higher activity of GST was found in concentrations 340, 380 and 420 mg/L of acetylsalicylic acid. TBARS, GPx and GST didn't show statistically significant activity in tested concentrations of acetylsalicylic acid. CONCLUSIONS The results revealed a statistically significantly higher degree of sensitivity in the embryonic stages of zebrafish compared to its juveniles. Acetylsalicylic acid did not cause statistically significantly higher antioxidative defence in zebrafish.

Abstract
Non-steroidal anti-inflammatory drugs (NSAIDs) are widely used for their anti-inflammatory, analgesic and antipyretic effects, however their use is associated with the broad spectrum of side effects observed in human as well as the experimental animals. Despite damaging activity of NSAIDs in upper gastrointestinal (GI) tract, these drugs exert deleterious influence in lower GI tract, including colon. The role of GI microflora in the pathogenesis of NSAIDs-induced experimental colonic damage is not completely understood. The aim of this study was 1) to evaluate the relative importance of the GI microflora on the experimental colonic damage in the presence of caused by NSAID, and 2) to assess the efficacy of antibiotic treatment with ampicillin on the process of healing of colitis. We compared the effect of vehicle, ASA applied 40 mg/kg intragastrically (i.g.) or the selective cyclooxygenase (COX)-2 inhibitor, celecoxib (25 mg/kg i.g.) without or with ampicillin treatment (800 mg/kg i.g.) administered throughout the period of 10 days, on the intensity of TNBS-induced colitis in rats. The severity of colonic damage, the alterations in the colonic blood flow (CBF) and myeloperoxidase (MPO) activity, the mucosal expression of TNF-α, IL-1β, COX-2, VEGF and iNOS and the plasma concentration of TNF-α and IL-1β were assessed. In all rats, the faeces samples as well as those from the colonic mucosa, blood, liver and spleen underwent microbiological evaluation for intestinal bacterial species including Escherichia coli and Enterococcus spp. The administration of TNBS resulted in macroscopic and microscopic lesions accompanied by the significant fall in the CBF, an increase in tissue weight and 4-5-fold rise in the MPO activity and a significant increase in the plasma IL-1β and TNF-α levels. ASA or celecoxib significantly increased the area of colonic lesions, enhanced MPO activity and caused the marked increase in colonic tissue weight and plasma IL-1β and TNF-α levels, as well as an overexpression of mRNA for IL-1β and TNF-α, COX-2, VEGF and iNOS in the colonic tissue. ASA and coxib also resulted also in a significant increase of E. coli counts in the stool at day 3 and day 10 day of the observation compared with the intact rats. Moreover, E. coli translocation from the colon to the blood and extraintestinal organs such as liver and spleen in the group of rats treated without or with ASA and coxib. E. coli was the most common bacteria isolated from these organs. Treatment with ampicillin significantly attenuated the ASA- or celecoxib-induced increase in plasma levels of IL-1β and TNF-α and suppressed the mucosal mRNA expression for IL-1β and TNF-β, COX-2, iNOS and VEGF in the colonic mucosa. Ampicillin administration caused a significant fall in the number of E. coli in the faeces at day 3 and day 10 of observation in ASA- and coxib-treated rats with colitis. Antibiotic therapy markedly reduced bacterial translocation to the colonic tissue and the extraintestinal organs such as the liver and spleen. We conclude that administration of ASA and to lesser extent of celecoxib, delays the healing of experimental colitis and enhances the alterations in colonic blood flow, proinflammatory markers such as IL-1β, TNF-α, COX-2, iNOS and VEGF and increased intestinal mucosal permeability resulting in the intestinal bacterial translocation to the blood, spleen and liver. Antibiotic treatment with ampicillin is effective in the diminishing of the severity of colonic damage, counteracts both the NSAID-induced fall in colonic microcirculation and bacterial E.coli translocation to the extraintestinal organs.

Abstract
BACKGROUND AND PURPOSE The use of non-steroidal anti-inflammatory drugs (NSAIDs) in the treatment of rheumatoid arthritis (RA) is limited by their toxicity. We evaluated the anti-inflammatory efficacy and safety of three novel modified NSAIDs, phospho-aspirin, phospho-ibuprofen and phospho-sulindac. EXPERIMENTAL APPROACH We determined the anti-inflammatory effects and gastrointestinal safety of the phospho-NSAIDs in the rat adjuvant arthritis model and studied their mechanism of action in cultured cells, Cytokines were measured with elisa and activation of nuclear factor-κB (NF-κB) by immunohistochemistry. KEY RESULTS All three phospho-NSAIDs showed less gastrointestinal toxicity than their parent compounds and demonstrated strong anti-inflammatory effects, essentially reversing joint inflammation and oedema. They have a broad but not uniform effect on the expression of relevant cytokines, in general decreasing IL-6 and IL-1β and increasing IL-10 levels in rat plasma and cultured cells. Phospho-sulindac and phospho-ibuprofen but not phospho-aspirin suppressed PGE(2) production in vitro, whereas phospho-aspirin (in contrast to aspirin) showed the same effect in vivo. In joint tissues, phospho-aspirin inhibited NF-κB activation, and suppressed inflammation and bone resorption. Phospho-aspirin also inhibited Jurkat T cell proliferation. In general, phospho-aspirin had greater efficacy but different effects upon inflammatory mediators compared with aspirin. The chemical modification of the parent NSAIDs seems crucial for their safety and efficacy. CONCLUSIONS AND IMPLICATIONS Phospho-aspirin, phospho-ibuprofen and phospho-sulindac were safer than their parent NSAIDs, were highly effective in rat adjuvant arthritis and inhibited many key mediators in the pathophysiology of RA. These novel compounds are promising candidate drugs for the treatment of RA and merit further evaluation.

Abstract
OBJECTIVES The current study was carried out to examine the influence of aspirin (400 mg/kg of body weight) and gum acacia (one g/day) and their combination on pancreatic, intestinal mucosal enzymes, intestinal tissue iron and zinc after 21 days of treatment on experimental rats. MATERIALS AND METHODS The treated rats were sacrificed and the pancreatic and intestinal lipase and amylase were measured photometrically. Moreover, zinc and iron level were determined using atomic absorption spectrometry. Intestinal sections were stained with hematoxylin and eosin. RESULTS The results showed that treatment with aspirin caused a marked decrease in pancreatic lipase and amylase compared with that of the control group. This decrease in aspirin treated group was accompanied by significant increase in the intestinal amylase, lipase, alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) compared with the control group. On the other hand, gum combined with aspirin caused a significant increase in pancreatic and intestinal lipase, amylase accompanied with significant increase in intestinal ALP and LDH compared with that of the control group. Concentration of Zn in wet weight of intestine showed a significant decrease in aspirin and aspirin combined with gum groups but it was increased significantly in gum acacia treated group. Histological analysis revealed intestinal epithelial damage in aspirin treated rats, this damage was not noticed with gum acacia treatment. Co-administration of gum in combination with aspirin indicated some changes of denuded intestinal mucosal cells compared with that of the control. CONCLUSIONS Gum acacia exhibited a protective property that can ameliorate the alterations induced hazardous effect of aspirin treatment.

Abstract
Distortion product otoacoustic emission (DPOAE) fine structure is due to the interaction of two major components coming from different places in the cochlea. One component is generated from the region of maximal overlap of the traveling waves generated by the two primaries and is attributed to nonlinear distortion (nonlinear component). The other component arises predominantly from the tonotopic region of the distortion product and is attributed to linear coherent reflection (reflection component). Aspirin (salicylate) ototoxicity can cause reversible hearing loss and reduces otoacoustic emission generation in the cochlea. The two components are expected to be affected differentially by cochlear health. Changes in DPOAE fine structure were recorded longitudinally in three subjects before, during, and after aspirin consumption. Full data sets were analyzed for two subjects, but only partial data could be analyzed from the third subject. Resulting changes in the two components of DPOAE fine structure revealed variability among subjects and differential effects on the two components. For low-intensity primaries, both components were reduced with the reflection component being more vulnerable. For high-intensity primaries, the nonlinear component showed little or no change, but the reflection component was always reduced.

Abstract
Pongamia pinnata has been advocated in Ayurveda for the treatment of various inflammatory conditions and dyspepsia. The present work includes initial phytochemical screening and study of ulcer protective and healing effects of methanolic extract of seeds of P. pinnata (PPSM) in rats. Phytochemical tests indicated the presence of flavonoids in PPSM. PPSM when administered orally (po) showed dose-dependent (12.5-50 mg/kg for 5 days) ulcer protective effects against gastric ulcer induced by 2 h cold restraint stress. Optimal effective dose of PPSM (25 mg/kg) showed antiulcerogenic activity against acute gastric ulcers (GU) induced by pylorus ligation and aspirin and duodenal ulcer induced by cysteamine but not against ethanol-induced GU. It healed chronic gastric ulcer induced by acetic acid when given for 5 and 10 days. Further, its effects were studied on various parameters of gastric offensive acid-pepsin secretion, lipid peroxidation (LPO) and nitric oxide (NO) and defensive mucosal factors like mucin secretion and mucosal cell shedding, glycoproteins, proliferation and antioxidants; catalase (CAT), superoxide dismutase (SOD) and glutathione (GSH) levels. PPSM tended to decrease acid output and increased mucin secretion and mucosal glycoproteins, while it decreased gastric mucosal cell shedding without any effect on cell proliferation. PPSM significantly reversed the increase in gastric mucosal LPO, NO and SOD levels caused by CRS near to the normal level while it tended to increase CAT and GSH level decreased by CRS and ethanol respectively. Thus, the ulcer protective effects of PPSM may be attributed to the presence of flavonoids and the actions may be due to its effects both on mucosal offensive and defensive factors.

Abstract
BACKGROUND The risk of hemorrhagic complications after extracorporeal shock-wave lithotripsy (ESWL) increases in patients with aspirin intake, but the hematoma-inducing mechanism has not been understood completely at the ultrastructural level. METHODS The effect off shock-waves on the kidneys of male Wistar-rats (n=24) was investigated in an experimental setting using a special ESWL device. Ultrastructural examination was performed by light-, transmission electron- and scanning electron microscopy. RESULTS Shock-wave induced tissue damage appeared in all kidneys independently of aspirin intake. Endothelial detachment, lethal cell injury, gaps and mechanical disruption of the glomerular basement membrane were regularly found. After 1 week, repair processes were completed with evidence of permanent fibrosis in some cases. CONCLUSIONS ESWL can induce modest as well as fatal damage to renal tissue cells. Therefore, after an ESWL-induced hematoma a second ESWL should not be performed within 1 week of the first treatment.

Abstract
This study evaluated the gastroprotective activity of DA-6034 against various ulcerogens including ethanol, aspirin, indomethacin, stress, and acetic acid. The basic mechanisms of DA-6034 as a defensive factor such as mucus secretion and endogenous prostaglandin E(2) synthesis were determined. Rats with gastric lesions induced by ethanol-HCl, aspirin, indomethacin, and stress that had been pretreated with DA-6034 orally showed a statistically significant decrease or decreasing tendency of the gastric lesion. In acetic acid-induced gastric lesions, repeated oral administration of DA-6034 exhibited a U-shape activity in ulcer healing, with the maximum and minimum inhibition being observed at 30 and 10 mg/kg/day, respectively. DA-6034 also increased the mucus content in the gel layer as well as endogenous prostaglandin E(2) synthesis. These results suggest that DA-6034 prevents gastric mucosal injury, and these gastroprotective activities appear to be due to the increase in the gastric defensive systems.

Abstract
The n-hexane, diethylether, ethyl acetate and methanol extracts from roots, leaves, stems and flowers with young leaves of Daphne pontica L. (Thymelaeaceae) were investigated for their in vivo anti-inflammatory and antinociceptive activities. For the anti-inflammatory activity assessment, carrageenan-induced hind paw edema, PGE(2)-induced hind paw edema and 12-O-tetradecanoyl-13-acetate (TPA)-induced mouse ear edema models and for the antinociceptive activity, p-benzoquinone-induced abdominal constriction test were used. Only ethyl acetate extracts of the roots showed significant anti-inflammatory activity on carrageenan-induced (22.7-32.0% inhibition) and PGE(2)-induced hind paw edema (3.2-27.3% inhibition) as well as 12-O-tetradecanoyl-13-acetate (TPA)-induced mouse ear edema (47.8-43.3% inhibition) models at 50 mg/kg dose without inducing any apparent gastric lesion or acute toxicity, whereas the other extracts were shown to be ineffective. In addition to roots, ethyl acetate extracts of the stems exhibited 19.5-29.9%; 5.3-23.9%; 36.6-28.1% inhibition on carrageenan-induced and PGE(2)-induced hind paw edema as well as 12-O-tetradecanoyl-13-acetate (TPA)-induced mouse ear edema models, respectively. On the other hand, none of the extracts showed any significant antinociceptive activity.

The present study was designed to investigate the gastrointestinal side effects of cycloxygenase (COX) inhibitor with varying selectivity, called the non-steroidal antiinflammatory drugs (NSAIDs) viz., non-selective COX-1 & 2 inhibitor--aspirin, prefentially selective COX-2 inhibitor--nimesulide and highly selective COX-2 inhibitor-celecoxib. Treatment with NSAIDs exhibited a decrease in the activity of rat intestinal brush border membrane associated enzymes such as sucrase, lactase, maltase and alkaline phosphatase as compared to the control in the duodenum, jejunum and ileum. The uptake of D-glucose and L-histidine in the everted intestinal sac was found to be decreased. Also the decease of glucose and histidine uptake was found to be dependent on the substrate concentration, temperature and the time interval of incubation. The physical state and composition of brush border membrane was found to be altered as evident in the FTIR spectrum, by appearance of new peaks while disappearance of certain peaks occurred which were characteristics of the control membrane. The changes in wave number as well as peaks height were also noticed. Alterations in protein profile of the membrane were demonstrated using SDS-PAGE analysis where disappearance of few bands and change in the relative intensities of the bands were noticed and correlated with the alterations that have taken place at the molecular level. Histological studies have depicted a marked decrease in the absorption surface area such as the villi height of the intestinal segment. In addition, crypt number also deceased in the treated animals, an indication that such changes also correlate well with the changes in the transport of the end product nutrients.

Abstract
Clinical studies reveal that aspirin intake to prevent myocardial and cerebral ischemia is associated with a significant increase in upper gastrointestinal hemorrhage requiring hospitalization and that nitroglycerin or long-acting nitrates significantly lower this risk. Nitroglycerin can increase gastric blood flow and slow gastric emptying. We hypothesized that both features contribute to its gastroprotective property. Fasted anesthetized rats (Study 1) and conscious mice (Studies 2 to 4) received intragastric nitroglycerin or vehicle. The effects of these two treatments on various parameters were assessed in Study 1, on blood pressure and gastric blood flow; Study 2, on acidified aspirin-induced gastric mucosal lesions; and Study 3, on the weight of gastric content. In Study 4, the effect of nitroglycerin, vehicle, or vehicle plus saline, on acidified aspirin-induced gastric mucosal lesion was assessed. Compared with vehicle, nitroglycerin decreased blood pressure and produced a mild but significant increase in gastric vascular conductance, blood flow, and volume of gastric content. The number and length of gastric mucosal lesions induced by acidified aspirin were significantly attenuated by intragastric nitroglycerin in a vasodilatory dose. Exogenous saline in a volume equivalent to the increase produced by nitroglycerin, however, did not attenuate the lesions. These experimental data are consistent with the clinical observation that nitrates lower the risk of aspirin-induced gastrointestinal complications. Confirmation of the efficacy of nitroglycerin and nitrates in preventing such aspirin-induced complications in controlled trials is worthy of consideration by clinical investigators.

Abstract
UNLABELLED This study was supported by grants of New Ideas Capability for Backbone Teachers in Universities of Heilongjiang and of Scientific Research foundation in Qiqihar Medical College. BACKGROUND/AIMS Ulcer recurrence and poor healing may be critically important to the development of serious gastrointestinal complications in patients with long-term non-steroid anti-inflammatory drugs (NSAIDs). The present study is to investigate the effects of aspirin on ulcer recurrence and healing quality and to explore the mechanism. METHODS Gastric ulcers were induced with acetic acid in rats; aspirin was administrated by gavage from day 25 to day 54 after ulcer induction. The gastric juice volume, pH, gastric mucus, gastric mucosal blood flow (GMBF) and prostaglandin E(2) (PGE(2)) were measured. The mRNA transcription of cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) were analyzed with RT-PCR and protein expression with Western blot. RESULTS The gastric juice volume was significantly increased in aspirin group compared with those of fasting or saline control groups (P<0.01); while the pH, mucus, GMBF and PGE(2) were significantly decreased in aspirin treated rats compared with those of other two groups (P<0.01). COX-2, evaluated with mRNA and protein expression, was significantly augmented in aspirin group compared with others. The quality of ulcer healing (QOUH) in Aspirin group was poorer than that of fasting or saline control groups. CONCLUSIONS Aspirin enhance the recurrence of gastric ulcer. The inhibition of cycloxygenase, mucus secretion and mucosal blood flow may be involved. Aspirin also impair the quality of ulcer healing.

Abstract
In order to investigate the effect of non-steroidal anti-inflammatory drugs (NSAIDs) on the development of rat immunity, indomethacin (IND; 0.25, 0.5, or 1.0 mg/kg/day), acetyl salicylic acid (ASA; 90, 180, or 360 mg/kg/day), or diclofenac sodium salt (DSS; 0.5, 1.0, or 2.0 mg/kg/day) suspended in 0.5% methylcellulose aqueous solution, was orally administered once daily to five pregnant Sprague-Dawley (IGS) rats per group on days 18-21 of gestation. After parturition, the serum IgM and IgG levels, the spleen weight, and the number of spleen cells were measured in 3- and 8-week-old pups. Afterwards, immunophenotyping analysis of splenocytes or peripheral blood lymphocytes and T-dependent antibody response were performed. The number of spleen cells in 3-week-olds increased when 1.0 mg/kg of IND and 180 mg/kg of ASA were administered. Immunophenotyping analysis using flow cytometry (FCM) indicated that the proportion and number of CD45RA(+) cells increased, and the proportion of CD3(-) NKR-P1A(+) cells decreased in males when dosed with IND at 1.0 mg/kg or ASA at 180 mg/kg. The serum anti-KLH IgG antibody titer decreased in the males of the IND 1.0 mg/kg dosing group, the serum levels of anti-KLH IgM, total IgM, and IgG were not changed at all. These changes disappeared in 8-week-old pups. There were no effects on any of the parameters in the 3- and 8-week-olds of the DSS treatment group. These results suggest that IND or ASA administration to dams during late gestation either causes a change in the lymphocyte subsets, or that they suppress the T-dependent antibody response in juvenile males. Both of these changes eventually recover to intact levels later on during development. These results will contribute to the development of a technique for the assessment of developmental immunotoxicity and generate data on the effect of prenatal administration of NSAIDs on the developmental immune system in pups.

Abstract
The ethanol extract of Toona ciliata Roemer (heart wood) was evaluated for its anti-ulcer activity against aspirin plus pylorous ligation induced gastric ulcer (antisecretory), HCl-ethanol induced ulcer (cytoprotective) and water immersion stress induced ulcer in rats. We found that Toona ciliata extract at a dose of 300mg/kg p.o. markedly decrease the incidence of ulcers in all the three models. Ethanol extract of Toona ciliata showed significant reduction in gastric volume, free acidity, total acidity and ulcer index. The plant extract also showed gastro protective activity (52.94%), whereas standard drug sucralfate showed 94.85%. Toona ciliata extract showed protection index 43.0% in water immersion stress induced ulcer, whereas standard drug omeprazole showed protection index 100%.

Abstract
A variety of 3-(4-methyl phenyl)-2-substituted amino-3H-quinazolin-4-ones were synthesized by reacting the amino group of 2-hydrazino-3-(4-methyl phenyl)-3H-quinazolin-4-one with a variety of aldehydes and ketones. The starting material 2-hydrazino-3-(4-methyl phenyl)-3H-quinazolin-4-one was synthesized from 4-methyl aniline. The title compounds were investigated for analgesic, anti-inflammatory, and ulcerogenic index activities. While the test compounds exhibited significant activity, compounds Al, A2, and A3 showed more potent analgesic activity and the compound A3 showed more potent anti-inflammatory activity when compared to the reference standard diclofenac sodium. Interestingly, the test compounds showed only mild ulcerogenic potential when compared to aspirin.

Abstract
BACKGROUND Renal side effects of nonsteroidal anti-inflammatory drugs (NSAIDs) are acute renal failure due to an impaired perfusion caused by inhibition of prostaglandin synthesis, acute allergic interstitial nephritis as well as acute toxic tubular necrosis. Moreover, chronic renal failure may occur due to a chronic interstitial nephritis or an analgesic nephropathy that is characterized by capillary sclerosis and papillary necrosis in addition to chronic interstitial nephritis. In contrast to acute renal insufficiency that may already occur after a single NSAID dose, analgesic nephropathy is a disease caused by long-term intake of NSAID compound analgesics and predominantly affects the middle and old age. CASE REPORT An 18-year-old patient with a 4-year history of NSAID compound analgesic intake presented to the urology department with right-sided flank pain and increased serum creatinine. An obstruction as well as nephrolithiasis were ruled out and the patient was referred to the medical department. Urinalysis showed leukocyturia, mild microhematuria as well as proteinuria of 2.2 g/day whereupon a diagnostic kidney biopsy was performed. Histology revealed a chronic nonpurulent destructive interstitial nephritis. After cessation of analgesic intake, the serum creatinine level fell to the normal range; however, a reduced creatinine clearance persisted indicating chronic renal damage. CONCLUSION The present case is remarkable in that chronic renal damage due to intake of a compound analgesic was already observed in an 18-year-old patient. In this context, the permission of NSAID compound analgesics and their free over-the-counter sale to adolescents need to be critically questioned.

Abstract
The objective of the present work was to evaluate the teratogenic effects of the interaction between acetylsalicylic acid (ASA) and ethanol on the epithelium of the lingual mucosa in rat fetuses. On the 10th pregnancy day, a single intraperitoneal ethanol dose (2.96 g/kg body weight) (Group I), ASA (200 mg/kg body weight) (Group II) and ASA plus ethanol, in the same doses (Group III), or saline (Group IV - control), were administrated. The epithelial alterations were assessed by means of histological and morphometric methods, on posterior dorsal, anterior dorsal and ventral regions of the tongue. ASA reduced, in rat fetuses, the ethanol deleterious effects on nuclear size in the epithelial prickle cell of the lingual mucosa. On the other hand, ASA did not influence the effects of ethanol in both epithelial layers of the lingual mucosa, when the nuclear shape, cell volume or epithelial layers thickness were evaluated.
