Abstract
BACKGROUND/OBJECTIVES Cyclosporine A (CSA) dosing has been complicated by considerable intra-patient and inter-patient variability in pharmacokinetics, which is affected by different factors. We aimed to assess the various factors that might affect the CSA dose and its plasma level. PATIENTS AND METHODS This retrospective study included paediatric cancer patients who underwent allogeneic hematopoietic stem cell transplant at the Children's Cancer Hospital Egypt 57357 from matched related donors with CSA as graft versus host disease prophylaxis. The CSA initial dose was 1.5 mg/kg IV Q12H. Then, it was titrated according to the level and drug toxicity. Cyclosporine A trough levels were assessed two to three times per week using the Emit 2000 cyclosporine-specific assay. Moreover, factors that may affect cyclosporine levels, such as age, sex, weight and the antifungal used, were analyzed to determine their effect on CSA plasma levels. RESULTS There were 119 patients included in the study. The median age was 10 years; and 43% of them used voriconazole as a prophylactic antifungal. The multivariate analysis revealed that female patients, those >9 years or on voriconazole reached the target level at low initial CSA doses. A higher probability (93%) of reaching the desired plasma level with doses 1.5 mg/kg IV Q12H was observed among patients >9 years, and on voriconazole. While those who were ≤9 years and not on voriconazole required doses >1.5 mg/kg IV Q12H, with an 89% probability of reaching the desired level. CONCLUSION This study suggests that the initial CSA dose should consider the patient's age and the antifungal used. Patients >9 years and/or on voriconazole may require lower initial CSA doses and could start with 1.5 mg/kg IV Q12H.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Cerastes cerastes is a snake found mainly in the Egyptian desert. Many studies were performed to explain the possible snake venom's pharmacological therapeutic effect in different autoimmune diseases. One of the most common auto-immune diseases is rheumatoid arthritis. Rheumatoid arthritis is characterized by a high release of pro-inflammatory and immune-modulatory cytokines. The reduction of these markers can indicate how effective is the administered drug. AIM OF THE STUDY This study aims to explore the potential pharmacological effects of cerastes venom in experimentally-induced RA in rats using Complete Freund's adjuvant - via different mechanisms - by assessing various tissue and serum parameters. MATERIALS AND METHODS The rats were assigned to negative control group, cerastes control group, positive control group, dexamethasone-treated group, infliximab-treated group, and cerastes-treated group. The study ended on the 20th day when serum and tissue samples were prepared for further evaluation of reduced glutathione, malondialdehyde, rheumatoid factor, tumor necrosis factor-α, interleukin-6, and nuclear factor kappa-light-chain-enhancer of activated B cells as well as relative expression of phosphorylated Janus-kinase, phosphorylated signal transducers and activators of transcription, nuclear factor erythroid 2-related factor 2, and receptor activator of nuclear factor Kappa-B ligand. In addition, a histopathological examination of different groups' knees joints, and spleen was done. RESULTS The results showed a significant improvement of arthritis induced in the cerastes-treated group in contrast to the positive control group in all assessed parameters. In addition, significant improvement of arthritis was observed in the histopathological examination of different groups' knees joints, and spleen. CONCLUSION These results revealed that cerastes snake venom has potent anti-inflammatory and immunomodulatory effects and can be used in the management of arthritis.

Abstract
Parkinson's disease (PD) drugs treat symptoms without inhibiting progression. In recent years, finding novel therapeutic medications that can halt disease progression has become crucial. Research on antidiabetic medicines is valuable in these investigations because of the parallels between the two disorders. Using Rotenone (ROT), a frequently used PD model, the possible neuroprotective benefits of Dulaglutide (DUL), an extended-acting glucagon-like peptide-1 agonist, were considered. Twenty-four rats were randomly assigned to 4 groups to complete this experiment (n = 6). 0.2 ml of the vehicle (1 ml of dimethyl sulfoxide (DMSO) diluted in sunflower oil) was administered to the standard control group subcutaneously with a 48-hour pause. The second group was administered ROT 2.5 mg/kg SC every 48 h for 20 days as a positive control group. The third and fourth groups were administered one dose of DUL each week (0.05 and 0.1 mg/kg SC, respectively) to their regimens. The mice received ROT (2.5 mg/kg SC) every 48 h for 20 days after receiving DUL for the initial dose (96 h later). The current study focused on the DUL's ability to preserve usual behavioral function, enhance antioxidant and anti-inflammatory pathways, inhibit alpha-synuclein (α-syn), and increase parkin levels. It is concluded that DUL acts as an antioxidant and an anti-inflammatory to protect against ROT-induced PD. However, more studies are required to support this finding.

Abstract
OBJECTIVE: Among other types of cancerous lesions, lung cancer is one of the prevalent causes of death. Trigonelline is a plant alkaloid, a significant constituent in coffee, and has shown health benefits in several disorders. The present study aims to investigate the potential therapeutic role of trigonelline in lung cancer. MATERIALS AND METHODS: Seventy-five BALB/C mice were assigned to five groups and treated for 150 days as follows (1): normal control group; (2) trigonelline only (50 mg/kg/ P.O) daily for the last thirty days; (3) urethane (1.5 g/kg B.w/i.p) at day one and sixty; (4) urethane and carboplatin (15 mg/kg i.p) for the last thirty days; and (5) urethane and trigonelline for the last thirty days. Tumor size was measured while blood and lung were collected for biochemical, western blotting analysis, and histological examinations. RESULTS: Urethane demonstrated significant changes in all biochemical and molecular parameters and histological examinations. In animals pretreated with urethane, trigonelline significantly reduced tumor size and restored Nrf2, NF-кB p65, Bcl-2, Cyclin D1, ICAM-1, and MMP-2, along with improving cGMP and active caspase three and refining histological architectures. CONCLUSIONS: Nrf2 signaling may be a promising therapeutic target for adenocarcinoma protection or management. Due to its multiple therapeutic effects on Nrf2, cyclin D1, NF-кB pathways, and the BAX/Bcl2 axis, trigonelline significantly induced cell cycle arrest and apoptosis. https://www.europeanreview.org/wp/wp-content/uploads/Graphical_Abstract-1.jpg.

Abstract
OBJECTIVE: Despite its evident renal toxicity, vancomycin is considered an effective glycopeptide antibiotic against life-threatening positive bacterial contagions. The current study aimed to investigate the potential protective effects of carvacrol as well as its underlying mechanism against vancomycin-induced nephrotoxicity. MATERIALS AND METHODS: The animals were randomly classified into four groups (8 rats per group). Group I, which served as a control group, received only vehicles. Group II received a single i.p. injection of 50 mg/kg of carvacrol for seven days. Group III received vancomycin (200 mg/kg, i.p.) as a singular daily dose for seven days. Carvacrol was administered to Group IV seven days prior to the daily vancomycin dose. RESULTS: The results revealed that carvacrol minimized vancomycin-induced renal injury as evidenced by lower serum cystatin C levels and kidney injury molecule-1 (KIM-1), in addition to a decline in renal damage caused by vancomycin as indicated in histopathological assessment. Furthermore, carvacrol significantly attenuated oxidative stress parameters and inflammatory mediators. Moreover, it downregulated Keap1, mitogen-activated protein kinase (p38MAPK), and nuclear factor kappa B (NF-κB) genes and proteins, along with controlling the NF-κB inhibitory protein (IkBα) and nuclear factor erythroid 2-related factor 2 (Nrf2) genes and proteins observed through streaming its genes. A molecular docking technique was also used to investigate the potential interactivity between carvacrol and proteins involved in regulating oxidative injury and inflammatory responses. CONCLUSIONS: The current study findings revealed that carvacrol administration before vancomycin could be a promising therapeutic approach for maceration of renal damage stimulated by vancomycin via controlling IkBα/MAPK and Keap1/Nrf2 signaling molecules. https://www.europeanreview.org/wp/wp-content/uploads/graphical-abstract-1.jpg.

Abstract
BACKGROUND Lung cancer has risen to the top of the list of cancer-related deaths worldwide. Aliskiren is a direct renin inhibitor. AIM This study aims to investigate the impact of cell signaling of Renin-Angiotensin system (RAS)/NF-κB on lung cancer by investigating the potential therapeutic effects of aliskiren for lung cancer treatment in urethane-induced lung cancer in mice. METHODS Male BALB/c mice were randomly assigned to one of five treatment groups for 150 days, including (1) normal control; (2) aliskiren (25 mg/kg/i.p) daily, (3) urethane at a dose of 1.5 g/kg (i.p) at Day 1 and 60 (nonsmall cell lung cancer[NSCLC] group) (4) NSCLC mice received carboplatin (15 mg/kg/i.p) every other day for the last 4 successive weeks and (5) NSCLC mice treated with aliskiren daily. Tumor size was determined based on blood sampling, and lungs were isolated for biochemical analysis, western blot analysis assay, and histopathological examination. RESULTS Urethane demonstrated significant changes in all biochemical and molecular parameters and histological patterns. Aliskiren-treated mice had significantly lower levels of NF-κB p65, Bcl-2, cyclin D1, ICAM-1, MMP-2, and Nrf2, with an increase in the catalytic activity of caspase-3 due to its RAS inhibitory mechanism. The combined urethane administration with aliskiren demonstrated a significant improvement in the histopathological examination. CONCLUSION RAS/NF-B cell signaling is a potential therapeutic target for preventing and treating lung adenocarcinoma, evidenced by the fundamental cytotoxic mechanism and attenuation of metastasis and angiogenesis induced by the treatment of NSCLC mice with aliskiren.

Abstract
Leurieus quinquestriatus (LQ) is a type of Egyptian scorpions. Prior studies have established the potential use of scorpion venoms in treating several autoimmune diseases. Therefore, the current study investigates the possible pharmacological effect of LQ venom in CFA-induced arthritis - through different mechanisms - by assessing different serum and tissue parameters. This study was divided into two phases: phase I was conducted to determine the lowest therapeutic dose of LQ scorpion venom, whereas phase II investigated the potential therapeutic effect of the chosen dose of LQ venom on induced arthritis through different mechanisms. The Wistar albino rats were divided equally and randomly into normal control group, LQ control group, arthritis control group, infliximab-treated group, and LQ-treated group. On day 20, blood and tissue samples were collected for further analysis of serum and tissue biomarkers as well as histopathological examination. The results revealed a potential therapeutic effect of LQ venom on arthritic-induced rats through a significant decrease in Rheumatoid Factor, Janus Kinase, Signal transducers and activators of transcription, Receptor activator of nuclear factor Kappa-B ligand, Tumor Necrosis Factor-alpha, Interleukin-6, Nuclear factor kappa-light-chain-enhancer of activated B cells and Malondialdehyde by 57%, 66%, 64%, 62%, 75%, 59%, 38%, and 69%, respectively as well as a significant increase in reduced glutathione, and Nuclear factor erythroid 2-related factor 2 by 102% and 360%, respectively. Histopathological examination of knee joint and spleen also revealed a substantial improvement, indicating the possible utilization of LQ venom in the treatment of rheumatoid arthritis.

Abstract
Nephrotoxicity is an indication for the damage of kidney-specific detoxification and excretion mechanisms by exogenous or endogenous toxicants. Exposure to vancomycin predominantly results in renal damage and losing the control of body homeostasis. Vancomycin-treated rats (200 mg/kg/once daily, for seven consecutive days, i.p.) revealed significant increase in serum pivotal kidney function, oxidative stress, and inflammatory biomarkers. Histologically, vancomycin showed diffuse acute tubular necrosis, denudation of epithelium and infiltration of inflammatory cells in the lining tubular epithelium in cortical portion. In the existing study, the conservative consequences of scopoletin against vancomycin nephrotoxicity was investigated centering on its capacity to alleviate oxidative strain and inflammation through streamlining nuclear factor (erythroid-derived-2) like 2 (Nrf2)/heme oxygenase-1 (HO-1) signaling and prohibiting the nuclear factor kappa B (NF-κB)/mitogen-activated protein kinase (p38 MAPK) pathway. With respect to vancomycin group, scopoletin pretreatment (50 mg/kg/once daily, i.p.) efficiently reduced kidney function, oxidative stress biomarkers and inflammatory mediators. Moreover, histological and immunohistochemical examination of scopoletin-treated group showed remarkable improvement in histological structure and reduced vancomycin-induced renal expression of iNOS, NF-κB and p38 MAPK. In addition, scopoletin downregulated (Kelch Like ECH Associated Protein1) Keap1, P38MAPK and NF-κB expression levels while upregulated renal expression levels of regulatory protein (IκBα), Nrf2 and HO-1. Furthermore, molecular docking and network approach were constructed to study the prospect interaction between scopoletin and the targeted proteins that streamline oxidative stress and inflammatory pathways. The present investigations elucidated that scopoletin co-treatment with vancomycin may be a rational curative protocol for mitigation of vancomycin-induced renal intoxication.

Abstract
BACKGROUND Methotrexate (MTX) is used potently for a wide range of diseases. However, hepatic intoxication by MTX hinders its clinical use. OBJECTIVES The present study was conducted to investigate the diallyl disulfide (DADS) ability to ameliorate MTX-induced hepatotoxicity. METHODS Thirty-two rats were randomly divided into four groups: normal control, DADS (50 mg/kg/day, orally), MTX (single i.p. injection of 20 mg/kg) and DADS+MTX. Liver function biomarkers, histopathological examinations, oxidative stress, inflammation, and apoptosis biomarkers were investigated. Besides, an in vitro cytotoxic activity study was conducted to explore the modulatory effects of DADS on MTX cytotoxic activity using Caco-2, MCF-7, and HepG2 cells. RESULTS DADS significantly reduced the increased serum activities of ALT, AST, ALP, and LDH. These results were confirmed by the alleviation of liver histopathological changes. It restored the decreased GSH content and SOD activity, while significantly decreased MTX-induced elevations in both MDA and NO2 - contents. The hepatoprotective effects were mechanistically mediated through the up-regulation of hepatic Nrf-2 and the down-regulation of Keap-1, P38MAPK, and NF- κB expression levels. In addition, an increase in Bcl-2 level with a decrease in the expression of both Bax and caspase-3 was observed. The in vitro study showed that DADS increased MTX antitumor efficacy. CONCLUSION DADS potently alleviated MTX-induced hepatotoxicity through the modulation of Keap-1/Nrf-2, P38MAPK/NF-κB and apoptosis signaling pathways and effectively enhanced the MTX cytotoxic effects, which could be promising for further clinical trials.

Abstract
Chemotherapeutic drugs are used effectively to manage wide types of malignancies, but their therapeutic use is limited due to their associated hepatic intoxication. The current study sheds light on the effect of phytochemicals berberine (BBR) and umbelliferone (UMB) on methotrexate (MTX)-induced hepatic intoxication. Forty-eight rats were allocated to normal, BBR (50 mg/kg orally for 10 days), UMB (30 mg/kg orally for 10 days), MTX (20 mg/kg at the 5th day), BBR+MTX, and UMB+MTX. With regard to MTX, the results of this investigation reveal potent amelioration of MTX hepatotoxicity by BBR and UMB through reduction of the elevated serum levels of ALT, ALP, AST, and LDH confirmed by the attenuation of histopathological abrasion in liver tissues. BBR and UMB markedly restored antioxidant status. More importantly, BBR resulted in reducing P38 mitogen-activated protein kinase (P38MAPK), nuclear factor kappa-B (NF-κB), and Kelch-like ECH-associated protein 1 (Keap-1) genes and enhanced mRNA expression of Nrf-2 (P < 0.05). Interestingly, in silico studies via molecular docking pinpointed the binding modes of BBR and UMB to the binding pocket residues of P38MAPK, NF-κB, and Keap-1 and demonstrated a promising inhibition of Keap-1, P38MAPK, and NF-κB. BBR and UMB reduced the expression of pro-apoptotic protein Bax and apoptotic protein caspase-3 as well as increased the expression of anti-apoptotic protein Bcl-2. Therefore, BBR and UMB may denote promising therapeutic agents that can avert hepatic intoxication in patients receiving MTX.

Abstract
Methotrexate (MTX) is a promising chemotherapeutic agent. Its medical use is limited by induced nephropathy. Our study was designed to explore the reno-protective effect of diallyl disulfide (DADS), an organosulfur compound of garlic oil, on MTX-induced nephropathy. Adult rats were randomly divided into 4 groups; normal control, DADS (50 mg kg-1 day-1 , p.o.), MTX (20 mg/kg, i.p.) and DADS+MTX. DADS significantly decreased serum creatinine, urea, uric acid, and albumin levels with an improvement of final body weight. Additionally, DADS markedly attenuated MTX-induced elevations in renal MDA and NO 2 - contents with an increase in GSH content and SOD activity. Mechanistically, DADS effectively down-regulated mRNA expression level of renal p38 and NF-κB. Additionally, DADS positively regulated the NRF2 gene with a remarkable inhibition of Keap-1 gene. Furthermore, DADS up-regulated BCL2 protein and remarkably suppressed the expression of both BAX and caspase-3 proteins. Overall, DADS has favorable renal protection against MTX-induced nephropathy via modulation of Keap-1/NRF2, p38/NF-κB, and BCL2/BAX/caspase-3 signaling. PRACTICAL APPLICATIONS: Diallyl disulfide is one of the organosulfur compounds of garlic oil. Our study demonstrated that DADS substantially alleviated the decline of kidney function and renal injury induced by MTX. The antioxidative, anti-inflammatory, and anti-apoptotic properties may constitute an important part of its therapeutic applications via regulation of p38/NF-κB, Keap-1/NRF2, and BCL2/BAX/caspase-3 signaling pathways. Therefore, DADS could be a potential therapeutic adjunct in cancer chemotherapy to decrease the associated side effects of MTX. It should be further explored clinically as a protective agent for MTX-treated cancer patients.

Abstract
OBJECTIVES Lung cancer is one of the most frequent types of cancers that lead to death. Sildenafil is a potent inhibitor of phosphodiesterase-5 and showed potential anticancer effects, which has not yet been fully evaluated. Thus, this study aims to investigate the potential anticancer effect of sildenafil in urethane-induced lung cancer in BALB/c mice. METHODS Five-week-old male BALB/c mice were treated with either (i) normal saline only, (ii) sildenafil only 50 mg kg-1/ P.O every other day for the last four successive weeks, (iii) urethane 1.5 gm kg-1 i.p (at day 1 and day 60), (iv) carboplatin after urethane induction, or (v) sildenafil after urethane induction. KEY FINDINGS It was shown that sildenafil significantly increased the levels of cGMP and Caspase-3 with a reduction of NF-κB, Bcl-2, Cyclin D1, intercellular adhesion molecule 1, matrix metalloproteinase-2 levels and normalisation of Nrf2 along with pronounced improvement in the histological patterns. CONCLUSIONS These results indicated that sildenafil markedly induces cell cycle arrest, apoptosis and inhibits the metastatic activity through activation of cyclic guanosine monophosphate/protein kinase G pathway and down-regulation of cyclin D1 and nuclear factor kappa light chain enhancer of activated B cells with downstream anti-apoptotic gene Bcl-2, which underscores the critical importance of future using sildenafil in the treatment of lung cancer.

Abstract
BACKGROUND Asthma is a complex inflammatory disease which affects multiple individuals worldwide especially pediatric ages. AIMS This study aimed to assess the possible protective effect of carvacrol, as natural antioxidant anti-inflammatory drug, against bronchial asthma induced experimentally in rats. MAIN METHODS Rats were randomly allocated into 5 groups; a normal control group, control drug group received only carvacrol, an asthma control group, a standard treatment group receiving dexamethasone (DEXA) and carvacrol treatment group. Bronchial asthma was induced by sensitization with i.p dose followed by challenge with intranasal dose of ovalbumin (OVA). 24 h after the last challenge, absolute eosinophil count (AEC) were determined in bronchoalveolar lavage fluids (BALF). Immunoglobulin E (IgE) was determined in serum. Inflammatory biomarkers like Interleukin-4 (IL-4), interleukin-5 (IL-5), interleukin 13 (IL-13), tumor necrosis factor-alpha (TNF-α) and interferon-gamma (IFN-γ) were also measured in BALF. Nitrosative stress biomarker namely inducible nitric oxide synthase (iNOS) was determined in BALF as well as oxidative stress biomarkers namely superoxide dismutase (SOD), glutathione (GSH) and malondialdehyde (MDA) were determined in lung tissue. Additionally, histopathological study, immunohistochemical study of UCN and western blot analysis of SP-D were performed. KEY FINDINGS Carvacrol administration significantly reduced the values of AEC, IgE, IL-4, IL-5, IL-13, TNF-α, IFN-γ, iNOS and MDA, while it significantly increased the values of SOD and GSH as compared to the asthmatic group. Histopathological, immunohistochemical and western blot study reinforced the biochemical results. SIGNIFICANCE Carvacrol may be a promising protective agent against bronchial asthma induced experimentally in rats.

Abstract
Nicorandil ameliorated doxorubicin-induced nephrotoxicity; this study aimed to show and explain the mechanism of this protection. A precise method was elucidated to study the effect of nicorandil on doxorubicin-induced nephrotoxicity in rats depending on the critical inflammation pathway TLR4/MAPK P38/NFκ-B. Adult male rats were subdivided into four groups. The 1st group was normal control, the 2nd group received nicorandil (3 mg/kg; p.o., for 4 weeks), the 3rd group received doxorubicin (2.6 mg/kg, i.p., twice per week for 4 weeks), and the fourth group was combination of doxorubicin and nicorandil for 4 weeks. Nephrotoxicity was assessed by biochemical tests through measuring Kidney function biomarkers such as [serum levels of urea, creatinine, albumin and total protein] besides renal kidney injury molecule-1 (KIM-1) and cystatin C], oxidative stress parameters such as [renal tissue malondialdehyde (MDA), reduced glutathione (GSH), SOD, catalase and nrf-2], mediators of inflammation such as [Toll like receptor 4 (TLR-4), Nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kB), p38 MAPK, Interleukin 1 beta (IL-1 β), and Tumor necrosis factor alpha (TNF-α)] and markers of apoptosis [BAX and Bcl-2 in renal tissue]. Finally, our data were supported by histopathology examination. Nicorandil pretreatment resulted in a significant decrease in nephrotoxicity biomarkers, oxidative stress markers, inflammatory mediators and prevented apoptosis through decreasing BAX and increasing Bcl-2 in renal tissues. Nicorandil prevented all the histological alterations caused by doxorubicin. Nicorandil is a promising antidote against doxorubicin-induced nephrotoxicity by neutralizing all toxicity mechanisms caused by doxorubicin through normalizing inflammatory cascade of TLR4/MAPK P38/NFκ-B.

Abstract
The current study was designed to explore the protecting effects of vitamin D and losartan in treatment of rheumatoid arthritis (RA). Animals were allotted to five groups: Group I received vehicles only (vehicle control). Group II was administered complete Freund's adjuvant (CFA) and did not receive any medication. The remaining three groups (III, IV, V) were given CFA followed by treatment with leflunomide, vitamin D or losartan, respectively for two weeks. Compelling increment in tumor necrosis factor (TNF-α), interleukin 6 (IL-6), rheumatoid factor (RF), erythrocyte sedimentation rate (ESR), malondialdehyde (MDA) level, white blood cells (WBCs), total cholesterol (TC) and triglycerides (TGs) was revealed in arthritic rats. This was associated with marked decline in glutathione (GSH) level, red blood cells (RBCs), hemoglobin (Hb), Platelets (Plts), hematocrit (Hct) and high density lipoprotein cholesterol (HDL). vitamin D or losartan significantly decreased TNF α, IL-6, RF, ESR, MDA, TC, TGs, WBCs and significantly increased RBCs, Hb, Hct, Plts and HDL. It could be concluded that vitamin D and losartan are able to repress the alterations associated with adjuvant-induced arthritis (AIA). This preserving effect might be partially attributed to antiarithritic, hypolipidemic and antianemic properties.

Abstract
Context: Prevalence of bronchial asthma massively increases worldwide, while the frequent therapies are still not sufficient. Polydatin, a naturally occurring glycoside, was known as to have anti-inflammatory and anti-oxidant effects. Objective: The current study aimed to investigate the possible protective effect of polydatin against experimental bronchial asthma in rats. Material and methods: Bronchial asthma was induced by ovalbumin (OVA) sensitization and challenge. Rats were randomly allocated into five groups; Group I (normal control group); Group II (asthma control group) received OVA; Group III (reference standard treatment group) received dexamethasone (1 mg/kg/day); Group IV (treatment group) received polydatin (200/mg/kg); and Group V (polydatin control group). The inflammatory biomarkers interleukin-4 (IL-4), IL-5, IL-13, tumor necrosis factor-alpha, interferon-gamma and absolute eosinophil count in bronchoalveolar lavage fluid (BALF), as well as serum immunoglobulin E were assessed, coupled with the oxido-nitrative stress biomarkers malondialdehyde and glutathione reduced levels and superoxide dismutase activity in the lung tissue, besides inducible nitric oxide synthase level in BALF. Western blot analysis of surfactant-D and immunohistochemical assay of urocortin (UCN) expression in the lung was performed. Results: Polydatin significantly reduced the inflammatory mediators and restored the normal values of oxidative and nitrosative stress biomarkers. It also significantly reduced the expression of surfactant-D and UCN as compared to asthma control. The histopathological study strongly augmented the biochemical results. Discussion and conclusions: Polydatin may be a promising protective agent against experimentally induced bronchial asthma. Modulation of SP-D and UCN expressions seems to mediate such protective effects.

Abstract
We report a case of transient blindness, part of a TURP syndrome, in a 65 year old man undergoing TUR of the prostate under centro-neuron block. Irrigating fluid consisted of 1.5% glycine. As a result, serum levels of glycine increased to 12,470 mols.l-1 (N176-332 mumols.l-1). We attribute this loss of vision to glycine toxicity.

Abstract
The aim of this investigation was to study the effect of dentin depth and patient's age on the shear bond strength of one dentin adhesive (ART Bond), using an Instron Universal testing machine at a cross-head speed of 0.5 mm/min. Forty human molar teeth were used and were divided into two main groups, twenty each representing two age groups of patients, i.e., between 20 to 30 years and between 30-40 years of age. Every group was further subdivided into two subgroups of different dentin depths, i.e., superficial and deep. Results were recorded in Kg/Cm2 and converted into MPa units, then tabulated and statistically analyzed. A Duncan's range statistic test at P < or = 0.05 showed statistically significant differences between the bond strength values for both age groups at different dentin depths, with the superficial dentin showing higher bond values, and there were also statistically significant differences between the bond strength values of the two age groups at the same dentin depth, with the older age group showing higher bond values.
