Abstract
The present study aims to evaluate the protective effect of Crataegus azarolus berries decoction extract (CAB-DE) against acetic acid-induced ulcerative colitis as well as the mechanisms implicated in such protection. Adult male Wistar rats were separated into seven groups: Control (H2O), acetic acid (AA), AA + various doses of CAB-DE (100, 200, and 400 mg/kg, b.w.,p.o.), and AA + sulfasalazine (100 mg/kg, b.w.,p.o.) or gallic acid (50 mg/kg, b.w.,p.o.) during 10 days. All rats were kept fasting overnight and ulcerative colitis was induced by rectal infusion of AA (300 mg kg-1, b.w.) (3%, v/v, 5 mL kg-1 b.w), for 30 s. The colon was rapidly excised and macroscopically examined to measure ulcerated surfaces and the ulcer index. In vitro, we found that CAB-DE exhibited a high antioxidant activity against DPPH radical (IC50 = 164.17 ± 4.78 μg/mL). In vivo, pretreatment with CAB-DE significantly protected the colonic mucosa against AA-induced damage by stimulating mucus secretion, reducing ulcer index as well as histopathological changes. Also, CAB-DE limited the oxidative status induced by AA in the colonic mucosa, as assessed by MDA and H2O2 increased levels and the depletion of both enzymatic activities and non-enzymatic levels. In addition, AA intoxication increased iron and calcium levels in colonic mucosa and plasma, while CAB-DE pretreatment regulated all intracellular mediators deregulation and significantly reduced inflammatory markers such as CRP (1.175 ± .04 ─ .734 ± .06 μg/dl) and ALP (161.53 ± 5.02 ─ 98.60 ± 4.21 UI/L) levels. We suggest that CAB-DE protected against AA-induced ulcerative colitis due in part to its antioxidant and anti-inflammatory properties.

Abstract
OBJECTIVE The aim of the present study was to investigate the effects of Grape seed extract (GSE) and exercise training on Doxorubicin (Doxo)-induced cardio, hepato and myo toxicities in healthy rats. METHODS Thirty male Wistar rats were randomly divided into five groups and daily treated by intraperitoneal route during two months either with ethanol 10% (Control); Doxo (1.5 mg/kg); Doxo + exercise (1.5 mg/kg + swimming exercise for 30 min twice a week); Doxo + GSE (1.5 mg/kg + GSE 2.5 g/kg); Doxo + GSE + exercise (1.5 mg/kg + GSE 2.5 g/kg + swimming exercise for 30 min twice a week). At the end of the treatment, tissues were collected and processed for the determination of oxidative stress (OS), intracellular mediators, energy fuelling biomarkers, carbohydrate metabolism parameters and muscle histopathology. RESULTS Doxo provoked OS characterised by an increased lipoperoxidation (LPO) and protein carbonylation and decreased antioxidant enzyme activities. Doxo also affected intracellular mediators, disturbed carbohydrate metabolism and energy fuelling in skeletal muscle as assessed by down-regulated Electron Transport Chain (ETC) complex activities leading in fine to altered skeletal muscle structure and function. CONCLUSION Almost all Doxo-induced disturbances were partially corrected with GSE and exercise on their own and more efficiently with the combined treatment (GSE + exercise).

Abstract
OBJECTIVES Ferroptosis is an iron-dependent, non-apoptotic mode of cell death characterized by excessive accumulation of reactive oxygen species (ROS). It plays an important role in the occurrence, development and treatment of various cancers, but little is known regarding the role of ferroptosis in hematologic malignancies. This review elaborates the regulatory mechanism of ferroptosis and the treatment opportunities for targeting ferroptosis in hematologic malignancies. METHODS A systematic literature review through PubMed was conducted to summarize the published evidence on the therapeutic potential of targeting ferroptosis in hematological malignant tumors. Literature sources published in English were searched, using the terms ferroptosis, leukemia, myelodysplastic syndrome, lymphoma and multiple myeloma. RESULTS More and more small molecules have been found to induce ferroptosis in hematologic malignancies through targeted iron metabolism and lipid peroxidation, and some ferroptosis inducers have been proved to have synergistic effect with other chemotherapeutic drugs. CONCLUSION This paper discusses the significance of ferroptosis in hematologic malignancies and provides a new way for the treatment of hematologic malignancies, and more experimental studies should be conducted in future.

Abstract
Trigonella foenum graecum (Fenugreek) is used in traditional phytomedicine for its anti-inflammatory, antiseptic, antidiabetic, and several other therapeutic virtues. The current study was intended to investigate the protecting effects of fenugreek seeds' aqueous extract (FSAE) using experimentally ethanol (EtOH)-induced gastric peptic ulcer in rats, as immense alcohol consumption can lead to gastric ulcer. Sixty adult male Wistar rats were divided into 6 groups of 10 each: control, EtOH (4 g/kg body weight [b.w.]), EtOH + several doses of FSAE (50, 100, and 200 mg/kg b.w.), and EtOH + Omeprazole (OM, 20 mg/kg orally [p.o.]). Animals were p.o. pretreated with FSAE for 21 days and exposed to a single oral administration of EtOH (4 g/kg b.w.) for 2 h. Gastric ulcer in rats was induced with a single dose of EtOH. Ulcer index, malondialdehyde (MDA), hydrogen peroxide (H2O2), and thiol groups (-SH) content in stomach, and antioxidant enzymes superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) were measured. Our recorded results showed that EtOH induced gastric damage, evidenced by the level of oxidative stress markers such as MDA and H2O2 in rats exposed to EtOH. However, significant increases in the activities of antioxidant enzymes were recorded, such as SOD, CAT, and GPx, and a decrease in nonenzymatic antioxidants, such as (-SH). Moreover, histopathological examinations showed the presence of lesions associated with severe tissue damage in the untreated rats. Interestingly, FSAE meaningfully protects against all gastric damages caused by EtOH. We propose that FSAE exhibits protective effects in EtOH-induced peptic ulcer in rats. This protection might be related to its antioxidant and anti-inflammatory properties as well as its opposite effects on some studied intracellular mediators.

Abstract
Acute myeloid leukemia (AML) is a heterogeneous disease with poor prognosis and limited treatment strategies. Determining the role of cell-extrinsic regulators of leukemic cells is vital to gain clinical insights into the biology of AML. Iron is a key extrinsic regulator of cancer, but its systemic regulation remains poorly explored in AML. To address this question, we studied iron metabolism in patients with AML at diagnosis and explored the mechanisms involved using the syngeneic MLL-AF9-induced AML mouse model. We found that AML is a disorder with a unique iron profile, not associated with inflammation or transfusion, characterized by high ferritin, low transferrin, high transferrin saturation (TSAT), and high hepcidin. The increased TSAT in particular, contrasts with observations in other cancer types and in anemia of inflammation. Using the MLL-AF9 mouse model of AML, we demonstrated that the AML-induced loss of erythroblasts is responsible for iron redistribution and increased TSAT. We also show that AML progression is delayed in mouse models of systemic iron overload and that elevated TSAT at diagnosis is independently associated with increased overall survival in AML. We suggest that TSAT may be a relevant prognostic marker in AML.

Abstract
BACKGROUND Diarrhea is a multifactorial gastrointestinal disorder responsible for about 5 million deaths annually. The chemical composition, the antioxidant activity of Crataegus azarolus berries aqueous extract (CABAE) as well as its protective effects against castor oil-induced diarrhea, oxidative stress, and inflammation in rat were studied. METHODS Sixty male rats were used and divided into six groups of ten animals in each: Control (C), castor oil (CO), CO+various doses of CABAE (100, 200, and 400 mg/kg b.w., p.o.), and CO+loperamide (LOP, 10 mg/kg b.w., p.o.). KEY RESULTS The CABAE showed relatively high levels of total polyphenols, flavonoids, and tannins. The LC-HRESIMS technique allowed the identification of 5 phenolic compounds and the major component is quinic acid. In vivo studies showed that CABAE protected against castor oil-induced diarrhea and intestinal fluid accumulation. The CABAE counteracted castor oil-induced lipoperoxidation, preserved GSH and thiol groups levels, and prevented the depletion of antioxidant enzyme activities, such as superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx). The CABAE administration also protected against castor oil-induced inflammatory markers (ALP and CRP) increase. More importantly, castor oil induced an increase of intracellular mediators, such as hydrogen peroxide, free iron, and calcium, while CABAE pretreatment significantly reversed them to near control levels. CONCLUSION The Crataegus azarolus berries aqueous extract significantly protected against diarrhea due in part to its antioxidant and anti-inflammatory properties.

Abstract
This study aimed to evaluate the influence of the carob powder (CP) and sweet whey powder (WhP) inclusion into weaning feed on the gut morphology, hemato-biochemical parameters, and antioxidant biomarkers. The addition of 10 g/kg (basal diet +10 g/kg of CP, of WhP) or the mixture (5 g/kg of CP and 5 g/kg of WhP) in the rabbit's standard diet was assessed. A total of 40 weaned New Zealand White rabbits (4 weeks old) was distributed according to body weight (BW) into four treatments (n = 10) and the feed additives were provided for 7 weeks. Tissue samples and blood were obtained after slaughter. Final BW, daily weight gain, feed conversion ratio, intestinal morphology, and carcass dressing were positively affected by CP-WhP treatments compared with the control diet. Also, CP-WhP treatments significantly increased total proteins, calcium and iron levels, fecal cholesterol excretion, total antioxidants capacity, superoxide dismutase, and catalase in different tissues and significantly decreased total cholesterol, triglycerides, and glucose in blood serum. These changes were associated with a diminution of blood tumor necrosis factor alpha, lipid peroxidation, and carbonyl proteins in rabbit tissues. Both the additives separately and especially in the mix may enhance productive performance, protein profile, gut function, immunity, and antioxidant activity, with reducing lipid peroxidation, essential inflammatory mediator, and protein-carbonyl residues of growing rabbits. These findings suggest that CP-WhP dietary supplementation provides novel insights into a variety of bioactive compound mixtures with different beneficial modes of actions.

Abstract
Simple Summary In this review, the authors propose a crosswise examination of cytarabine-related issues ranging from the spectrum of clinical activity and severe toxicities, through updated cellular pharmacology and drug formulations, to the genetic variants associated with drug-induced phenotypes. Cytarabine (cytosine arabinoside; Ara-C) in multiagent chemotherapy regimens is often used for leukemia or lymphoma treatments, as well as neoplastic meningitis. Chemotherapy regimens can induce a suboptimal clinical outcome in a fraction of patients. The individual variability in clinical response to Leukemia & Lymphoma treatments among patients appears to be associated with intracellular accumulation of Ara-CTP due to genetic variants related to metabolic enzymes. The review provides exhaustive information on the effects of Ara-C-based therapies, the adverse drug reaction will also be provided including bone pain, ocular toxicity (corneal pain, keratoconjunctivitis, and blurred vision), maculopapular rash, and occasional chest pain. Evidence for predicting the response to cytarabine-based treatments will be highlighted, pointing at their significant impact on the routine management of blood cancers. Abstract Cytarabine is a pyrimidine nucleoside analog, commonly used in multiagent chemotherapy regimens for the treatment of leukemia and lymphoma, as well as for neoplastic meningitis. Ara-C-based chemotherapy regimens can induce a suboptimal clinical outcome in a fraction of patients. Several studies suggest that the individual variability in clinical response to Leukemia & Lymphoma treatments among patients, underlying either Ara-C mechanism resistance or toxicity, appears to be associated with the intracellular accumulation and retention of Ara-CTP due to genetic variants related to metabolic enzymes. Herein, we reported (a) the latest Pharmacogenomics biomarkers associated with the response to cytarabine and (b) the new drug formulations with optimized pharmacokinetics. The purpose of this review is to provide readers with detailed and comprehensive information on the effects of Ara-C-based therapies, from biological to clinical practice, maintaining high the interest of both researcher and clinical hematologist. This review could help clinicians in predicting the response to cytarabine-based treatments.

Abstract
Myelodysplasticsyndrome (MDS) and acute myeloid leukemia (AML) are clonal hematopoietic stem cell diseases leading to an insufficient formation of functional blood cells. Disease-immanent factors as insufficient erythropoiesis and treatment-related factors as recurrent treatment with red blood cell transfusions frequently lead to systemic iron overload in MDS and AML patients. In addition, alterations of function and expression of proteins associated with iron metabolism are increasingly recognized to be pathogenetic factors and potential vulnerabilities of these diseases. Iron is known to be involved in multiple intracellular and extracellular processes. It is essential for cell metabolism as well as for cell proliferation and closely linked to the formation of reactive oxygen species. Therefore, iron can influence the course of clonal myeloid disorders, the leukemic environment and the occurrence as well as the defense of infections. Imbalances of iron homeostasis may induce cell death of normal but also of malignant cells. New potential treatment strategies utilizing the importance of the iron homeostasis include iron chelation, modulation of proteins involved in iron metabolism, induction of leukemic cell death via ferroptosis and exploitation of iron proteins for the delivery of antileukemic drugs. Here, we provide an overview of some of the latest findings about the function, the prognostic impact and potential treatment strategies of iron in patients with MDS and AML.

Abstract
We investigate the antioxidant activity and protective effects of the aqueous leaf extract of Pistacia lentiscus (AELPL) against ulcerative colitis induced by acetic acid infusion through the rectum in Wistar rats. Phytochemical analyses allowed the identification of numerous phenolic compounds in P. lentiscus leaves such as flavonoids (isoquercetin and luterolin), flavonols (catechin, rutin, and kaempferol), phenolic acids (ellagic and dicaffeoylquinic), and tanins. Acetic acid exposure induced macroscopic colonic mucosal lesions with hemorrhage, congestion, edema, and the development of an expected oxidative stress state revealed by an increase in lipoperoxidation and carbonylation of proteins and a decrease in sulfhydryl (SH) group levels and antioxidant enzyme activities such as superoxide dismutase, catalase, glutathione-S-peroxidase, and glutathione transferase, as well as an increase in the inflammatory cytokine, interleukin-6, in the colon and plasma. Administration of acetic acid also increased plasma and tissue levels of hydrogen peroxide and rates of iron and free calcium, whereas AELPL significantly and dose-dependently attenuated all the previous biochemical alterations and intracellular mediator perturbations. In conclusion, the AELPL exhibited a potent cytoprotective effect against acetic acid-induced colitis in rats, mainly through its antioxidant and anti-inflammatory activities.

Abstract
Despite its crucial importance in numerous physiological processes, iron also causes oxidative stress and damage which can promote the growth and proliferation of leukemic cells. Iron metabolism is strictly regulated and the related therapeutic approaches to date have been to restrict iron availability to tumor cells. However, since a new form of iron-catalyzed cell death has been described, termed ferroptosis, and subsequently better understood, iron excess is thought to represent an opportunity to selectively kill leukemic cells and spare normal hematopoietic cells, based on their differential iron needs. This review summarizes the physiology of iron metabolism and its deregulation in leukemia, the known ferrotoposis pathways, and therapeutic strategies to target the altered iron metabolism in leukemia for the purposes of initiating ferroptosis in these cancer cells.

Abstract
Rosa canina is a well-known medicinal plant used in folk remedy that alleviates various disorders, including inflammation, gastritis, and diarrhea. The objective of this investigation was to identify and quantify the phenolic components of R. canina methanolic extract (RCME) and to determine its protective action with dextran sulfate sodium (DSS)-generated mice colitis model. RCME chemical analysis was done using Liquid Chromatography-Electrospray Ionization-Tandem Mass Spectrometry, and experimental animals received RCME at different doses before colitis induction by oral DSS administration during 7 days. Another group received sulfasalazine as a positive control. Colitis damages and RCME benefits were assessed using histopathological and biochemical changes and improvements. Many phenolic compounds have been identified. In addition, the DSS intoxication induced an alteration of colonic epithelium associated with an oxidative stress state. DSS administration led to an increase or decrease of intracellular mediators such as free iron and ionizable calcium. RCME consumption effectively protected against colonic histological/biochemical alterations induced by DSS intoxication providing support for the traditional use of this plant.

Abstract
Iron, an indispensable element for life, is involved in all kinds of important physiological activities. Iron promotes cell growth and proliferation, but it also causes oxidative stress damage. The body has a strict regulation mechanism of iron metabolism due to its potential toxicity. As a cancer of the bone marrow and blood cells, leukemia threatens human health seriously. Current studies suggest that dysregulation of iron metabolism and subsequent accumulation of excess iron are closely associated with the occurrence and progress of leukemia. Specifically, excess iron promotes the development of leukemia due to the pro-oxidative nature of iron and its damaging effects on DNA. On the other hand, leukemia cells acquire large amounts of iron to maintain rapid growth and proliferation. Therefore, targeting iron metabolism may provide new insights for approaches to the treatment of leukemia. This review summarizes physiologic iron metabolism, alternations of iron metabolism in leukemia and therapeutic opportunities of targeting the altered iron metabolism in leukemia, with a focus on acute leukemia.

Abstract
Cinnamon bark and evergreen oak acorns, natural sources of functional ingredients, are effective for those suffering from diarrhea, constipation and irritable bowel syndrome. This study aimed to evaluate the dissimilar phytochemical composition and the opposite potential actions of Cinnamomum cassia bark (ACCE) and Quercus ilex aqueous extracts (GIAE) on gastrointestinal (GI)-physiological activities and disruptions. An HPLC-PDA/ESI-MS assay was used to identify the distinctive qualitative and quantitative profiles of phenolic compounds. The GI-physiological action of both extracts on gastric emptying (GE) and gastrointestinal transit time (GIT) were evaluated using the phenol-red colorimetric method and a test meal containing charcoal/gum arabic in water. Loperamide (LOP)-induced colonic constipation and delayed emptying of the stomach were used to explore the reverse effects of ACCE/GIAE on GI disorders. HPLC-PDA/ESI-MS showed that the main phenolic compounds detected in ACCE are trans-cinnamic acid, quinic acid, protocatechuic acid and rosmarinic acid, while gallic acid, quinic acid and protocatechuic acid are the major chemical constituents found in GIAE. GIAE at two doses (150 and 300 mg kg−1) exerted a reduction of GE (66.40% and 60.87%, respectively) compared to a control group (70.25%). However, ACCE at the same concentrations induced contradictory actions on GE/GIT in comparison to GIAE and antagonistic synthetic pharmacological drugs in rats. The protective effect of CCAE against constipation induced by LOP in rats was accompanied by a strong antioxidant property related to moderation of intracellular-mediator disorders. An absence of toxic actions was revealed in the case of the hematological profile and biochemical parameters. Hence, in-depth investigations of these nutrients of both extracts may help future researchers to derive the underlying mechanisms and potential molecular targets for the development of physiologically functional foods and future therapies. Cinnamon bark and evergreen oak acorns, natural sources of functional ingredients, are effective for those suffering from diarrhea, constipation and irritable bowel syndrome.![]()

Abstract
Thyme is a rich source of bioactive phytochemicals and it is frequently used in folk-medicine to treat gastroenteritis irritations. The current study was performed to examine the potential of Thymus vulgaris aqueous extract (TV-AE) to protect against delayed gastric emptying (DGE) and colonic constipation in rats. Stomach ulcer was caused by a single oral dose administration of indomethacin (INDO) (30 mg kg−1 of body weight). Constipation was induced following intravenous intoxication of rats with vinblastine (VINB) (2 mg kg−1 of body weight) for one week. The effect of TV-AE at two graduated doses (100 and 200 mg kg−1) on DGE, gastrointestinal transit (GIT) and constipated rats and biochemical parameters was estimated using phenol red, charcoal meal test and colorimetric methods, respectively. The phytochemical-profile of TV-AE was explored using high-performance liquid chromatography coupled with photodiode array detection and electrospray ionization-mass spectrometry (HPLC-PDA/ESI-MS). INDO and VINB caused a significant reduction in (P < 0.05) DGE and GIT and colonic motility dysfunction. TV-AE consumption remarkably (P < 0.05) attenuated the DGE (from 58.56% to 69.871%) and difficulty in evacuating stools (from 48.5 to 55.5 fecal pellets per rat) and balanced the GIT (65% to 71%). These GI-ameliorative effects were accompanied by reversed INDO/VINB-related oxidative changes, lipid-metabolism alteration and intracellular pathway moderation. HPLC-PDA/ESI-MS-analysis identified several chemical constituents including rosmarinic acid, quinic acid, luteolin-7-o-glucoside, protocatechuic acid and trans-cinnamic acid. Thus, TV-AE bioactive components may be used as medicinal substances to regulate/attenuate gastrointestinal–physiological activities and disturbances, which support its pharmacological use. Thyme is a rich source of bioactive phytochemicals and it is frequently used in folk-medicine to treat gastroenteritis irritations.![]()

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ficus carica fruit, a source of bioactive functional ingredients, have been traditionally long time used for its medicinal benefits as they improve the digestive system, treating constipation and used as a natural laxative. AIM OF THE STUDY The recent study was investigated the ameliorative effect of Ficus carica L. aqueous extract (FCAE) on delayed gastric emptying and ulcerative colitis-improved motility disturbances in dextran sulfate sodium (DSS)-induced acute colitis in rats. MATERIALS AND METHODS Wistar rats were assigned randomly and received 5% DSS for seven days. Ulcerative colitis diagnosis was confirmed by clinical signs, visible fecal blood and histopatological evaluation. The estimation of the action of colitis on TGI and constipation as well as the protective effect of extract, the intestinal biochemical and physiological parameters were measured using the charcoal meal test, loperamide (Lop)-induced constipation as well as spectrophotometric assays. FCAE (150 and 300 mg kg-1) was administered orally once per day for seven days 1 h after the loperamide treatment. Phenol-red colorimetric method was used to explore the action of FCAE on gastric emptying process. RESULTS Ulcerative colitis caused a significantly gastrointestinal motility inhibition in normal rats and notably aggravated the constipation in LOP group. Oppositely, FCAE oral intake significantly increased levels of the gastrointestinal transit ratio and gastric emptying by accelerating of their times. Moreover, constipation severity induced by colitis was remarkably reduced in the FCAE treatment group, as demonstrated by a marked management of fecal parameters, water content, oxidative stress indicators, lipid metabolism, and intracellular mediators. Phytochemical analysis of FCAE revealed the presence of carbohydrates, polysaccharides, phenolic acids as gallic acid, chlorogenic acid, syringic acid and ellagic acid, and flavonoids (e.g. rutin, catechin, epicatechin and apeginine). CONCLUSIONS The obtained results indicated that FCAE exhibits a natural laxative effect without provoking diarrhea and ameliorates functional gastrointestinal (GI) and motility disorders thus justifying its traditional usage.

Abstract
Grape seed powder (GSP) contains high amount of bioactive polyphenols usually used as nutritional supplement or food preservatives due to their antioxidant and scavenging properties. The purpose of the present work was to evaluate the safety of increasing dosage GSP (w/w) of 0.5%, 5%, 10% and 20% corresponding to 0.4, 4, 8 and 16 g/kg bw respectively, when administered sub-chronically to Wistar rats in a 2 month-repeated dosing oral toxicity trial. Overally GSP had no effect on food intake, decreased body weight gain without affecting brain, liver, heart or kidney relative weight. GSP did not alter haematology except an increase in platelets, slightly decreased plasma transaminases, creatinine, urea and xanthine oxidase activity, without affecting uricemia, glycemia, triglyceridemia and cholesterolemia. GSP did not affect intracellular mediators as calcium, free iron or H2O2, but exerted real anti-oxidative properties in the four selected organs as assessed by lower lipoperoxidation and carbonylation, higher non protein thiols and antioxidant enzyme activities as CAT, GPx and SOD. Besides GSP exerted anti-inflammatory properties as supported by lower plasma IL17 A and CRP and higher IL10 and adiponectin. Histopathologically GSP provoked the dilation of heart and kidney arterioles and increased the size of the hippocampal dentate gyrus reflecting higher neurogenesis as assessed by Ki-67 labeling. Under the experimental conditions of the current study, GSP appeared as highly safe even when administered at very high dosage and could find potential applications in a variety of biotic or abiotic stresses-induced multi-organ dysfunction.

Abstract
Spleen is the largest lymphoid organ and obesity is related to an elevated risk of immunity dysfunction. The mechanism whereby fat adversely affects the spleen is poorly understood. This study was designed to assess the effectiveness of grape seed and skin extract (GSSE) and orlistat (Xenical, Xe) on high-fat diet (HFD)-induced spleen lipotoxicity. Obese rats were treated either with GSSE (4 g/kg body weight) or Xe (2 mg/kg body weight) or GSSE+Xe and monitored for weight loss for 3 months. Animals were then sacrificed and their spleen used for the evaluation of lipotoxicity-induced oxidative stress and inflammation as well as the putative protection afforded by GSSE and Xe treatment. HFD induced body weight gain and glycogen accumulation into the spleen; ectopic deposition of cholesterol and triglycerides and an oxidative stress characterized by increased lipoperoxidation and carbonylation; inhibition of antioxidant enzyme activities, such as catalase, glutathione peroxidase, and superoxide dismutase; depletion of zinc and copper; and a concomitant increase in calcium. HFD also increased plasma pro-inflammatory cytokines, such as interleukin (IL)-6, IL-17A, tumour necrosis factor alpha, and C-reactive protein, and decreased plasma IL-10 and adiponectin. Importantly, GSSE counteracted all the deleterious effects of HFD on spleen (i.e., lipotoxicity, oxidative stress, and inflammation) and the best protection was obtained when combining Xe+GSSE. Combining GSSE with Xe prevented against fat-induced spleen lipotoxicity, oxidative stress, and inflammation; this combination may be beneficial in other diseases related to the spleen.

Abstract
In the CNS, including the optic nerve, oligodendrocytes play a critical role in the myelination of axons. Oligodendrocytes are exceptionally sensitive to insults to the CNS, such as injury, ischemia, or inflammation, which result in the loss of oligodendrocytes and myelin and eventually secondary axon degeneration. Oligodendrocytes are sensitive to excitotoxic insults mediated by overactivation of their AMPA ionotropic glutamate receptors. Phenolic compounds, which are widely distributed in fruits and vegetables, received the great attention of scientists due to their antioxidant activities and free radical scavenging abilities. Chlorogenic acid (CGA) has been demonstrated to possess potent neuroprotective activities against oxidative stress in various cellular models and pathological conditions. Hence, CGA protect against oxidative stress and excitotoxic insults mediated by AMPA receptors and that the protective mechanisms involve free radical scavenging, Ca2+ handling in the cytosol, and modulating antioxidant enzyme system. CGA was associated with the protein kinase A (PKC) signaling pathways transduction. Caspases and calpains have been studied as apoptotic mediators and cell death in this model of AMPA toxicity. Inhibitors of caspases initiators, caspases 1, 8, and 9, the upstream of caspase 3 effectors, have totally abrogated the protective activity of CGA. Inhibitors of calpains also totally abrogated the protective activity of CGA. In addition, a potential role for the CGA in inhibiting Bax in oligodendrocyte cell model undergoing AMPA is inducing excitotoxic death. Our results indicate that CGA exhibits a protective potential via antioxidant and apoptosis caspases and calpains dependent against AMPA-mediated excitotoxicity, and these finding indicate that CGA is able to be a good candidate for preventive approach for neurodegenerative disorders associated with loss and damage in oligodendrocytes and AMPA-mediated excitotoxicity.

Abstract
The phytochemical composition and the effect of the green and ripe Opuntia ficus-indica juice on some gastrointestinal (GI) physiological parameters such as stomach emptying and small-intestinal motility and permeability were determined in rats administered multiple concentrations of the prickly pear juice (5, 10, and 20 mL kg-1, b.w., p.o.). Other separate groups of rats were received, respectively; sodium chloride (0.9%, b.w., p.o.), clonidine (α-2-adrenergic agonist, 1 mg kg-1, b.w., i.p.), yohimbine (α-2-adrenergic antagonist, 2 mg kg-1, b.w., i.p.), and loperamide (5 mg kg-1, b.w., p.o.). In vivo reverse effect of juice on GI physiological parameters was investigated using a charcoal meal test, phenol-red colorimetric method, loperamide-induced acute constipation, and castor oil-caused small-bowel hypersecretion. However, the opposite in vitro influence of juice on intestinal permeability homeostasis was assessed by the Ussing chamber system. Mature prickly pear juice administration stimulated significantly and dose dependently the GI transit (GIT; 8-26%) and gastric emptying (0.9-11%) in a rat model. Conversely, the immature prickly pear juice reduced gastric emptying (7-23%), GIT (10-28%), and diarrhea (59-88%). Moreover, the standard drugs have produced their antagonistic effects on GI physiological functions. The permeability of the isolated perfused rat small-intestine has a paradoxical response flowing prickly pear juices administration at diverse doses and maturity grade. Most importantly, the quantitative phytochemical analyses of both juices showed a different composition depending on the degree of maturity. In conclusion, the prickly pear juice at two distinct phases of maturity has different phytochemical characteristics and opposite effects on GI physiological actions in rat.

Abstract
Recently, the biosafety and potential influences of nanoparticles on central nervous system have received more attention. In the present study, we assessed the effect of aluminium oxide nanoparticles (Al2O3-NPs) on spatial cognition. Male Wistar rats were intravenously administered Al2O3-NP suspension (20 mg/kg body weight/day) for four consecutive days, after which they were assessed. The results indicated that Al2O3-NPs impaired spatial learning and memory ability. An increment in malondialdehyde levels with a concomitant decrease in superoxide dismutase activity confirmed the induction of oxidative stress in the hippocampus. Additionally, our findings showed that exposure to Al2O3-NPs resulted in decreased acetylcholinesterase activity in the hippocampus. Furthermore, Al2O3-NPs enhanced aluminium (Al) accumulation and disrupted mineral element homoeostasis in the hippocampus. However, they did not change the morphology of the hippocampus. Our results show a connection among oxidative stress, disruption of mineral element homoeostasis, and Al accumulation in the hippocampus, which leads to spatial memory deficit in rats treated with Al2O3-NPs.

Abstract
Artemisia campestris L. has been widely used in alternative medicine to treat digestive system diseases, particularly gastroesophageal disorders. In the present investigation, we studied the putative protective effect of Artemisia campestris aqueous extract (ACAE) against gastro-esophageal reflux (GER)-induced esophagitis in rats. The experimental ophagitis was induced by the ligation of the pylorus as well as the junction between the forestomach and the corpus. We firstly found that ACAE administration at 100, 200 and 400 mg/kg, b.w., p.o. significantly protected GER-induced macroscopic and histological injuries in the esophagus tissue. Our extract also counteracted GER-induced esophagus lipoperoxidation, restored the depletion of antioxidant enzyme activities such as superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) as well as thiol groups levels. Furthermore, we showed that acute GER provoked an increase in esophagus mucosa hydrogen peroxide (H2O2), free iron and calcium levels, whereas ACAE treatment reversed all GER-induced intracellular mediators' disturbances. In conclusion, we suggested that ACAE had potent protective effects against esophagitis due, in part, to its antioxidant properties as well as its opposite effect on some intracellular mediators.

Abstract
Lithium (Li) is a relevant mood stabilizer metal for the treatment of bipolar disorder (BD), as it protects from both depression and mania and reduces the risk of suicide. However, Lihas some clinical concerns as a narrow therapeutic index requiring routine monitoring of the serum level. The present study was designed to analyze the cardio-toxic side effect of Li and the ability of grape seed and skin extract (GSSE) to protect the heart against such toxicity. After 30days of exposure to Li (0, 2, 5 and 100mg/kg bw) and prevention with GSSE (4000mg/kg bw), rats were killed by decapitation and their heart processed for Li-induced oxidative stress. Data mainly showed that Li increased lipoperoxidation and protein carbonylation, it decreased superoxide dismutase and glutathione peroxidase activities, altered acetylcholinesterase (AChE) activity and increased the pro-inflammatory cytokine interleukin 6 (IL-6). Interestingly, GSSE efficiently alleviated all the deleterious effects of Li especially in low therapeutic doses. Based on our results, GSSE could be proposed as a nutritional supplement to mitigate the cardiotoxic side effects of lithium.

Abstract
BACKGROUND Massive alcohol drinking can lead to gastric ulcer. In the present study we investigated the gastroprotective effect of Citrus sinensis peel aqueous extract (CSPE) and Hesperidin (H) in ethanol (EtOH) induced oxidative stress and peptic ulcer in rats. METHODS Seventy adult male Wistar rats were divided into seven groups of 10 each: control, EtOH (4 g/kg b.w.), EtOH + various doses of CSPE (100, 200 and 400 mg/kg, b.w.), EtOH + Hesperidin (50 mg/kg, p.o.) and EtOH + Omeprazole (OM, 20 mg/kg, p.o.). Animals were perorally (p.o.) pre-treated with CSPE during 15 days and intoxicated with a single oral administration of EtOH (4 g/kg b.w.) during 2 h. Gastric ulcer was induced in rats with a single dose of ethanol (EtOH). Ulcer index, gene expression of gastric cyclooxygenase-2 (COX-2), tumor necrosis factor alpha (TNF-α), malondialdhyde (MDA), hydrogen peroxide H2O2 and Thiol groups (-SH) content in stomach and antioxidant enzymes superoxide dismutase (SOD), catalase (CAT) and gluthation peroxidise (GPx) were measured. Furthermore, histopathological examinations were performed. RESULTS The results showed that ethanol induced gastric damage, improving oxidative stress markers level such as MDA (121 ± 4.45 nmol/mg proteins) and H2O2 (24.62 ± 1.04 μmol/mg proteins), increased pro-inflammatory cytokine (TNF-α level), as well as the expression of COX-2 in the ethanol group. However, a significant depletion of enzymatic and non-enzymatic antioxidants were observed, such as, GPx (72%), SOD (57.5%), CAT (41.6%) and -SH (50%). The lesions were associated with severe histopathological damage. The both Citrus sinensis peel aqueous extract (CSPE) and hesperidin significantly protect against all gastric damages caused by ethanol administration in rats. CONCLUSIONS We propose that CSPE and hesperidin exhibit protective effects in EtOH-induced peptic ulcer in rat. This protection might be related in to part its antioxidant properties as well as its opposite effects on some studied intracellular mediators.

Abstract
Irinotecan, a chemotherapy drug, can cause acute diarrhea immediately after administration. Hence, the present study was designed to investigate the gastrointestinal (GI) disturbances after an intraperitoneal (IP) administration of irinotecan in rats.Twenty Wistar rats were separated into two groups of ten. Group A was considered as a control group (NaCl, 0.9%). Group B was treated with irinotecan at a single dose of 200mgkg-1. The rats were observed for defecation. For the enteropooling test, the animals were sacrificed by decapitation 1h post-treatment. The small intestine was excised and the fluid was milked into a graduated tube and the volume was measured. After centrifugation of intraluminal liquid, the electrolyte concentrations in the supernatants were measured by flame photometry. Oxidative stress parameters and intracellular mediators as well as the MPO activity were determined in intestinal mucosa by colorimetric methods Our result indicated that irinotecan produces an intestinal fluid accumulation and electrolyte transport disorders. These effects were associated with augmented intestinal MPO activity and oxidative damage such as an elevation of MDA production and a depletion of enzymatic and non-enzymatic antioxidants. More than that, drug administration provoked intracellular mediator disturbances such as a free iron, H2O2 and calcium levels. In conclusion, the data suggest that irinotecan caused a gastrointestinal stress via oxidative stress-induced disturbances in water and electrolyte transport in the intestinal mucosa in rats.

Abstract
The synthesis of hybrid nanomaterials has greatly increased in recent years due to their special physical and chemical properties. However, information regarding the environmental toxicity associated with these chemicals is limited, in particular in the aquatic environment. In the present study, an experiment was performed in which the marine bivalve (Ruditapes decussatus) was exposed for 14days to 2 concentrations of zinc oxide-decorated Au nanoparticles (Au-ZnONPs: Au-ZnONP50=50μg/L; Au-ZnONP100=100μg/L). The stability and resistance of Au-ZnONPs in the natural seawater were assessed by combining transmission electron microscopy and dynamic light scattering. Inductively coupled plasma-atomic emission spectroscopy revealed uptake of these nanoparticles within clams and their ability to induce metallic deregulation. The results obtained indicate that Au-ZnONPs induce biochemical and histological alterations within either the digestive gland or gill tissues at high concentration. This was deduced from the significant increase in H2O2 level, superoxide dismutase and catalase activities and malondialdehyde content. Furthermore, the toxicity of Au-ZnO nanoparticles was linked with the increase of intracellular iron and calcium levels in both tissues. Histological alterations in gill and digestive gland were more pronounced with Au-ZnONP100 and this is likely related to oxidative mechanisms. Gill and digestive gland are differentially sensitive to Au-ZnONPs if the exposure concentration is higher than 50μg/L. In conclusion, the parameters considered here could constitute reliable biomarkers for evaluation of hybrid nanoparticles toxicity in environmental model organisms. In addition, based on the results obtained, gill and digestive gland of R. decussatus could be proposed as models to detect harmful effects of hybrid nanoparticles.

Abstract
The purpose of this study is to examine the gastrointestinal disorders after injection of vinblastine (2 mg kg-1 b.w. i.v.) in rats. Animals were divided into two equal groups: Group 1 was considered as a control group (NaCl, 0.9%). Group 2 was treated with intravenous injection of vinblastine for 7 days. Loperamide (2 mg kg-1) was injected in a saline solution subcutaneously to induce constipation in another group of rats during the same period. Fecal parameters of the different groups have been determined. At the end of the experiment, animals were anaesthetized and sacrificed by decapitation. The intestinal mucosa specimens were examined for lipid peroxidation, sulfhydryl groups (-SH) and protein carbonylation as well as antioxidant enzyme activities and intracellular mediators. Gastrointestinal motility was realized by the test meal (10% charcoal in 5% gum arabic). In result, statistically significant decreases in the fecal number and water content collected during 24 h were detected in the vinblastine group, but less important than loperamide control group. The animals treated with vinblastine, showed also a significant decrease (13%) of GIT, lower than that of loperamide (34%). The intestinal tissues from vinblastine-treated rats were showed a significant increase in lipoperoxydation and H2O2 production as well as a significant depletion of enzymatic and non-enzymatic antioxidants. Added to that, a disruption of intracellular iron and calcium levels was observed. Therefore, the present study provide the first strong evidence that vinblastine induced numerous disruptions in gastrointestinal which are related to oxidative stress and intracellular mediators disorders.

Abstract
Recent studies demonstrate that glyphosate exposure is associated with oxidative stress and some neurological disorders such as Parkinson's pathology. Therefore, phytochemicals, in particular phenolic compounds, have attracted increasing attention as potential agents for neuroprotection. In the present study, we investigate the impact of glyphosate on the rat brain following i.p. injection and the possible molecular target of neuroprotective activity of the phenolic fraction from Morus alba leaf extract (MALE) and its ability to reduce oxidative damage in the brain. Wistar rats from 180 to 240 g were i.p. treated with a single dose of glyphosate (100 mg kg-1 b.w.) or MALE (100 μg mL-1 kg-1 b.w.) for 2 weeks. Brain homogenates were used to evaluate neurotoxicity induced by the pesticide. For this, biochemical parameters were measured. Data shows that MALE regulated oxidative stress and counteracted glyphosate-induced deleterious effects and oxidative damage in the brain, as it abrogated LDH, protein carbonyls, and malonyldialdehyde. MALE also appears to be able to scavenge H2O2 levels, maintain iron and Ca2+ homeostasis, and increase SOD activity. Thus, in vivo results showed that mulberry leaf extract is a potent protector against glyphosate-induced toxicity, and its protective effect could result from synergism or antagonism between the various bioactive phenolic compounds in the acetonic fraction from M. alba leaf extract.

Abstract
It is unknown whether gender has an impact on brain injury in obesity, and, if so, whether treatment with grape seed and skin flour could exert a protective effect. Both male and female rats were fed a standard diet (SD) or a high fat diet (HFD) during eight weeks and treated with high dosage grape seed and skin flour (GSSF). Fat-induced oxidative stress was evaluated into the brain with a special emphasis on transition metals determination. HFD induced male-cholesterol overload (+78.12%) and an oxidative stress status characterized by increased lipoperoxidation (+68.97%), carbonylation (+40.28%), decreased antioxidant enzyme activities as glutathione peroxidase (-61.07%) and manganese-superoxide dismutase (-35.47%) but not catalase. Additionally HFD depleted the brain from manganese (-71.31%) and dropped glutamine synthetase activity (-36.16%), without affecting copper nor iron nor their associated enzymes. HFD also altered intracellular mediators as superoxide anion (+36.12%), calcium (+44.41%) and also calpain (+76.54%) a calcium dependent protease. Importantly all these alterations were detected exclusively in male brain and were efficiently corrected upon GSSF treatment. In conclusion, GSSF has the potential to alleviate the deleterious lipotoxic effect of HFD treatment that occurred in male brain and perhaps in post-menauposal female brain.

Abstract
The present study aimed to investigate the inhibitory effect of chamomile decoction extract (CDE) on intestinal glucose absorption as well as its protective role against high fat diet (HFD)-induced obesity and lipotoxicity in rats. We used the Ussing chamber system to investigate the effect of CDE on intestinal transport of glucose. Male Wistar rats were fed HFD for six weeks to provoke obesity. CDE (100mg/kg, b.w. p.o.) has been per orally administered to HFD fed rats. Ex vivo, we found that CDE significantly and dose-dependently increased intestinal absorption of glucose. In vivo, HFD increased the body, liver and kidney weights, while CDE treatment showed a significant protective effects. High fat diet induced also a lipid profiles disorder and a disturbances in kidney and liver function parameters. Moreover liver and kidney lipotoxicity is accompanied by an oxidative stress status characterized by increased lipoperoxidation, depletion of antioxidant enzymes activity and non-enzymatic antioxidant (-SH groups and GSH) levels as well as increased levels of free iron, hydrogen peroxide (H2O2) and calcium. However, treatment with CDE alleviated all the deleterious effects of HFD feed. These findings suggest that chamomile decoction extract can be used as functional beverage against obesity, hyperglycemia and hyperlipidemia.

Abstract
This study aimed to investigate the antiulcer and antioxidant activities of myrtle berry seed aqueous extract (MBSAE) in a peptic ulcer model induced by ethanol in male Wistar rats. MBSAE is rich in total polyphenols, total flavonoids, and unsaturated fatty acids, particularly linoleic (18:2) and oleic (18:1) acids. MBSAE also exhibited in vitro antioxidant activity using 2,2-diphenyl-1-picrylhydrazyl (DPPH) (IC50 = 172.1 μg/mL) and superoxide anion (IC50 = 200.24 μg/mL) scavenging activities. In vivo, MBSAE provided dose-dependent protection against ethanol-induced gastric and duodenal macroscopic and histological alterations. Also, it inhibited secretory profile disturbances and lipid peroxidation, and preserved normal antioxidant enzyme activities and nonenzymatic antioxidant levels. More importantly, we showed that acute alcohol intoxication increased gastric and duodenal calcium, hydrogen peroxide, and free iron levels, whereas MBSAE treatment protected against intracellular mediator deregulation. In conclusion, we suggest that MBSAE has potent protective effects against alcohol-induced peptic ulcer in rat. This protection might be related in part to its antioxidant properties as well as its opposite effects on some studied intracellular mediators.

Abstract
Obesity is associated with an oxidative stress status, which is defined by an excess of reactive oxygen species (ROS) vs. the antioxidant defense system. We report in this present work, the link between fat deposition and oxidative stress markers using a High Fat Diet-(HFD) induced rat obesity and liver-oxidative stress. We further determined the impact of chronic administration of 3-keto-1, 5-BPs 1 (a & b) (40μg/kg/8 weeks/i.p.) on liver's level. In fact, exposure of rats to HFD during 16 weeks induced body and liver weight gain and metabolic disruption with an increase on liver Alanine amino transférase (ALAT) and Aspartate aminotransférase (ASAT) concentration. HFD increased liver calcium level as well as free iron, whereas, it provoked a decrease on liver lipase activity. HFD also induced liver-oxidative stress status vocalized by an increase in reactive oxygen species (ROS) as superoxide radical (O2), hydroxyl radical (OH) and Hydrogen peroxide (H2O2). Consequently, different deleterious damages as an increase on Malon Dialdehyde MDA, Carbonyl protein PC levels with a decrease in non-protein sulfhydryls NPSH concentrations, have been detected. Interestingly, our results demonstrate a decrease in antioxidant enzymes activities such as superoxide dismutase (SOD), catalase (CAT), glutathione peroxidases (GPx) and peroxidases (POD). Importantly, 3-keto-1,5-bisphosphonates treatment corrected the majority of the deleterious effects caused by HFD, but it failed to correct some liver's disruptions as mineral profile, oxidative damages (PC and NPSH levels) as well as SOD and lipase activities. Our investigation point that 3-keto-1,5-bisphosphonates could be considered as safe antioxidant agents on the hepatic level that should also find other potential biological applications.

Abstract
In the present study, we investigated the effect of grape seed and skin supplement (GSSS), on lactating dairy ewes' production. Ten dairy pregnant ewes from northern Tunisia were allocated to two groups: control diet (C) and supplemented with 20 % (w/w) GSSS. The experiment lasted for 8 weeks and took place after 2 months of lambing. During the experiment, daily milk yield and milk composition were determined. Supplementation of the diet with GSSS increased milk production (P < 0.001), calcium (P < 0.01), free iron (P < 0.01) and urea content (P < 0.001) but had no effect on milk fat nor protein. From these data, it is concluded that the inclusion of GSSS in sheep diets increased significantly ewes' milk yield.

Abstract
Context Myrtle, Myrtus communis L. (Myrtaceae), is a medicinal plant well known for its richness in phenolic compounds and its beneficial effects for the treatment of gastrointestinal disorders.Objective In the present work, the protective effect of the myrtle berry seed aqueous extract (MBSAE) against esophageal reflux (ER)-induced damage in esophagus mucosa as well as the mechanisms implicated was determined.Materials and methods In this respect, adult male Wistar rats were used and divided into seven groups: Control, ER, ER + various doses of MBSAE, ER + famotidine or ER + gallic acid. The ER was induced and animals were per orally (p.o.) treated with MBSAE or reference molecules during 6 h. The phytochemical screening was determined using colourimetric analysis.Results MBSAE is rich in total polyphenols and anthocyanins and exhibited an important in vitro antioxidant activity. In vivo, we firstly found that ER led to marked macroscopic and histopathological changes in esophagus. The results showed, also, that the ER was accompanied by a state of oxidative stress as assessed by an increase of lipid peroxidation, a decrease of the sulphhydryl groups and glutathione levels, as well as antioxidant enzyme activities depletion. MBSAE abrogated all morphological, histopathological and biochemical alterations. We showed also that ER increased esophageal calcium, hydrogen peroxide (H2O2) and free iron levels while MBSAE treatment protected against intracellular mediators deregulation.Conclusion Our data suggest that MBSAE exerted a potential protective effect against ER-induced damage in rat esophagus, at least in part, due to its antioxidant properties.

Abstract
Chronic kidney disease (CKD) is a syndrome characterized by progressive and irreversible deterioration of renal function linked to slow destruction of renal parenchyma, eventually terminating in death when sufficient number of nephrons are damaged. Oxidative stress is commonly observed in CKD patients resulting from an imbalance between overproduction of reactive oxygen species (ROS) and impairment of defence mechanisms. Grape seed extract (GSE) is a polyphenolic mixture exhibiting antioxidant and anti-inflammatory properties. We conducted an interventional pilot study of supplementation with GSE capsules (GSE group, n = 23) or placebo (control group, n = 10) on CKD patients. Blood and urine samples were collected at baseline and after a six-month-long supplementation period to determine some renal function biomarkers, as well as antioxidant, anti-inflammatory and haematological parameters. GSE improved glomerular filtration rate (GFR) and proteinuria, increased the anti-oxidant status as assessed by high plasma catalase and superoxide dismutase and also lowered lipoperoxidation and carbonylation. GSE ameliorated inflammation by decreasing CRP, triglyceridemia and counteracted anemia and thrombocytopenia. Supplementation with 2 g GSE/day for six months improved some kidney function parameters of CKD patients and this beneficial effect of GSE seems to be mediated at least partly by its antioxidant and anti-inflammatory properties.

Abstract
INTRODUCTION Lung fibrosis is a common side effect of the chemotherapeutic agent bleomycin and current evidence suggests that reactive oxygen species play a key role in the development of lung injury. We examined whether grape seed and skin extract (GSSE), a polyphenolic mixture exhibiting antioxidant properties, is able to protect against bleomycin-induced lung oxidative stress and injury. METHODS Rats were pre-treated during three weeks either with vehicle (ethanol 10% control) or GSSE (4g/kg), then administered with a single high dose bleomycin (15mg/kg) at the 7th day. RESULTS Bleomycin increased lung lipoperoxidation, carbonylation and decreased antioxidant enzyme activities as catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GPx). Bleomycin also induced copper depletion from the lung and iron accumulation within the lung, but had no effect on either zinc nor manganese. Correlatively bleomycin decreased the copper associated enzyme tyrosinase, increased the zinc dependent lactate dehydrogenase (LDH) and did not affect the manganese dependent glutamine synthetase. GSSE efficiently counteracted almost all bleomycin-induced oxidative stress, biochemical and morphological changes of lung tissue. CONCLUSION Data suggest that GSSE exerts potent antioxidant properties that could find potential application in the protection against bleomycin-induced lung fibrosis.

Abstract
BACKGROUND The aim of this study was to evaluate the protective effects of subacute pre-treatment with chamomile (Matricaria recutita L.) decoction extract (CDE) against stimulated neutrophils ROS production as well as ethanol (EtOH)-induced haematological changes and erythrocytes oxidative stress in rat. METHODS Neutrophils were isolated and ROS generation was measured by luminol-amplified chemiluminescence. Superoxide anion generation was detected by the cytochrome c reduction assay. Adult male wistar rats were used and divided into six groups of ten each: control, EtOH, EtOH + various doses of CDE (25, 50, and 100 mg/kg, b.w.), and EtOH+ ascorbic acid (AA). Animals were pre-treated with CDE extract during 10 days. RESULTS We found that CDE inhibited (P ≤ 0.0003) luminol-amplified chemiluminescence of resting neutrophils and N-formyl methionylleucyl-phenylalanine (fMLF) or phorbolmyristate acetate (PMA) stimulated neutrophils, in a dose-dependent manner. CDE had no effect on superoxide anion, but it inhibited (P ≤ 0.0004) H2O2 production in cell free system. In vivo, CDE counteracted (P ≤ 0.0034) the effect of single EtOH administration which induced (P < 0.0001) an increase of white blood cells (WBC) and platelets (PLT) counts. Our results also demonstrated that alcohol administration significantly (P < 0.0001) induced erythrocytes lipoperoxidation increase and depletion of sulfhydryl groups (-SH) content as well as antioxidant enzyme activities as superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx). More importantly, we found that acute alcohol administration increased (P < 0.0001) erythrocytes and plasma hydrogen peroxide (H2O2), free iron, and calcium levels while the CDE pre-treatment reversed increased (P ≤ 0.0051) all these intracellular disturbances. CONCLUSIONS These findings suggest that CDE inhibits neutrophil ROS production and protects against EtOH-induced haematologiacal parameters changes and erythrocytes oxidative stress. The haematoprotection offered by chamomile might involve in part its antioxidant properties as well as its opposite effect on some intracellular mediators such as H2O2, free iron, and calcium.

Abstract
Arsenic is a metalloid found in water, soil, and air from natural and anthropogenic sources, and is commonly found in inorganic as well as organic forms. The clinical use of arsenic trioxide (As2O3) in the treatment of acute promyelocytic leukemia (APL) is limited by its cardiotoxic side effects. Grape seed and skin extract (GSSE) is a polyphenolic mixture with antioxidant properties. This study aimed to evaluate the protective effect of GSSE on arsenic-induced cardiac oxidative stress and injury. Animals exposed to 2.5 mg/kg As2O3 for 21 days exhibited a relevant increase in heart lipoperoxidation, protein carbonylation, and inflammation, as well as a drop in the activity of antioxidant enzymes such as catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GPx). In addition, As2O3 disturbed heart lipidemia and lipase activity, transition metals distribution and the associated enzymes, intracellular mediators such as calcium and the associated calpain activity, as well as myocardial architecture. Treatment with 4 g/kg GSSE protected against most of the deleterious effects provoked by As2O3. Our data suggest that GSSE has the potential to protect against As2O3-induced cardiotoxicity.

Abstract
OBJECTIVES The present study was carried out to determine the antidiarrheal effects of myrtle (Myrtus communis L.) berries seeds aqueous extract (MBSAE) from Tunisia as well as the involvement of its antimicrobial and antioxidant properties in such protection. METHODS Adult male wistar rats were used and divided into six groups of ten each: control, Castor oil, Castor oil + Loperamide and Castor oil + various doses of MBSAE. Animals were per orally (p.o.) pre-treated with MBSAE for one hour and intoxicated by castor oil acute oral administration. KEY FINDINGS Our results demonstrated that the MBSAE is rich in total and condensed tannins and exhibited a broad spectrum of antibacterial activity. In vivo, we found that MBSAE administration induced a significant dose-dependent protection against diarrhoea and intestinal fluid accumulation. Castor oil-induced intestinal hypersecretion was accompanied by an oxidative stress status in the intestine. More importantly, we showed that acute diarrhoea was accompanied by an increase in intestinal mucosa hydrogen peroxide (H2 O2 ), calcium and free iron levels while MBSAE pre-treatment reversed all castor oil-induced intracellular mediators disturbances. CONCLUSIONS We suggest that MBSAE had a potent protective effects against castor oil-induced acute diarrhoea due in part to its antioxidant and antimicrobial properties.

Abstract
The present study has been designed to investigate the ameliorative effect of grape seed proanthocyanidins (GSP) on cadmium (Cd)-induced oxidative damage in rat erythrocytes. Twenty four male Wistar rats were divided into four groups: control, GSP-treated group (100 mg kg(-1) body weight (BW)), Cd-treated group (cadmium chloride, 5 mg kg(-1) BW), and GSP + Cd-treated group in which GSP was orally pre-administered 90 min before Cd intoxication for 4 weeks. At the end of the experimental period, blood samples were collected by cardiac puncture and were processed for various biochemical estimations. The extent of oxidative damage in isolated rat erythrocyte membrane was assessed by measuring lipid peroxidation, enzymatic and non-enzymatic content, calcium ion (Ca(2+))/magnesium ion (Mg(2+))-ATPase and sodium ion (Na(+))/potassium ion (K(+))-ATPase activities, free iron, calcium, hydrogen peroxide (H2O2) concentration, and osmotic fragility. Our results unveiled that Cd intoxication significantly increased the erythrocyte lipid peroxidation markers and decreased the activity of enzymatic and non-enzymatic markers in erythrocytes. Conversely, GSP pretreatment significantly prevented the decrease in the activities of antioxidant enzymes and membrane-bound ATPases. GSP also restored the levels of iron, calcium, and H2O2 in Cd-treated rats. Conformational changes in erythrocytes of various groups were also determined using morphological and ultrastructural electron microscopic analysis. The findings of our study clearly revealed that GSP affords superior protection against Cd-induced reactive oxygen species generation, lipid peroxidation, and free radical generation in Cd-treated rats, which presumably reflects the ability of this flavonoid to protect erythrocytes and lymphocytes of rats from the toxic effects of Cd.
