Objective: Elucidation of the protective effect of lutein against carbofuran induced toxicity in Wistar rats.Methods: Male Wistar rats were assigned into 5 groups of five animals. Group I normal received sunflower oil, Group 2 received carbofuran (5 mg/kg b. w.) alone. Group 3-5 received carbofuran plus lutein (50, 100 and 200 mg/kg body weight) respectively. Carbofuran and lutein administration were continued for 14 d. Neurobehavioural markers such as rotarod, grip strength test and pain threshold tests were carried out. After sacrifice, tissues were analysed for marker enzymes, antioxidant enzymes as well as oxidative stress markers.Results: Low dose of carbofuran was found to produce neurobehavioral problems as seen from the decreased retention time during rotarod test, endurance capacity in grip strength test and increased endurance capacity in pain threshold test. They were found to be significantly reversed by oral lutein administration. Administration of lutein restored the decreased acetylcholinesterase produced by carbofuran. Serum and tissue marker enzymes such as lactate dehydrogenase, creatine kinase and gamma-glutamyltransferase, which were increased by carbofuran were decreased by lutein administration. Lutein administration also reduced oxidative stress parameters which were increased by carbofuran.Conclusion: The results showed that carbofuran induced toxicity in male Wistar rats was reversed by carotenoid lutein.

Background: Growing evidence supports relationship between depression and inflammation. The hypothesis of involvement of inflammatory pathways in depression is supported by the findings of increased levels of proinflammatory cytokines. So, we decided to evaluate the effect of sitagliptin on depression using forced swim test (FST) and possible effects of sitagliptin on serum oxidative stress markers and cytokine gene expression in rat hippocampus.Methods: FST model was used to evaluate antidepressant effect in male wistar rats. Rats in group I (control group) were given normal saline, group II (standard group) were given fluoxetine, group III and IV (test groups) were given sitagliptin 5 mg/kg and sitagliptin 9 mg/kg respectively. All the drugs in all groups were given per orally. At the end, animals were sacrificed and blood was collected. Hippocampus of rat brain was dissected out. Serum oxidative stress markers and hippocampal pro inflammatory cytokine gene expression analysis was carried out.Results: Sitagliptin 5 mg/kg and 9 mg/kg showed reduction in depressive symptoms and hippocampal cytokine gene expression in comparison to control. In case of serum oxidative stress markers, there was statistically significant reduction in nitric oxide levels with stagliptin 9 mg/kg. Although there was a decrease in the levels of catalase and increase in the levels of glutathione with standard and test groups, the results were not statistically significant.Conclusions: The present study showed significant antidepressant effect activity of standard and test groups. Hence, further research should be carried out to substantiate above results.

Abstract. This study was designed to investigate the hepatorenal protective effects of trévo, on cadmium-induced renal and hepatic injury in male Wistar rats. Methods. Fifteen healthy male Wistar rats were divided into three groups of five rats per group. Group I (control); group II (35mg/kg cadmium chloride (CdCl2); Group III (2 ml/kg trévo+ CdCl2. The rats were treated with trévo (2ml/kg orally) and administered CdCl2 3 hrs later. Twenty-four hours after the last administration rats were sacrificed and blood was collected via cardiac puncture and processed for hematological parameters and assessment of urea, creatinine (CREA), and uric acid (UA), alanine aminotransferase (ALT), aspartate aminotransferase (AST), and albumin (ALB). The liver and kidney were excised and processed for markers of oxidative stress. Results intraperitoneal administration of 35 mg/kg of CdCl2 caused a significant increase in serum concentration of urea, CREA, UA, AST, ALT, while the concentration of ALB was significantly lower (P<0.0001). CdCl2 caused a significant reduction in packed cell volume, hemoglobin while the total white blood cell count, neutrophils, lymphocytes, monocytes, eosinophils, and basophils were increased. Oxidative stress was significantly pronounced in the liver and kidney of rats exposed to CdCl2 as observed in the high concentration of malondialdehyde, decreased concentration of glutathione, the activity of catalase, superoxide dismutase, and glutathione-S-transferase. Pretreatment with trévo was able to significantly prevent the anemic, oxidative damage, renal and hepatic injury initiated by CdCl2. Conclusions. The study reveals that trévo is effective in attenuating cadmium-induced hepatorenal toxicity in male Wistar rats.

Over the years, Formaldehyde (FA) has been linked to increased generation of reactive oxygen species (ROS), leading to oxidative stress and cognitive decline. However limited numbers of studies have shown the effect of eugenol on FA induced toxicity in Wistar rats. Therefore this study aimed at investigating the effects of eugenol on the FA induced toxicity in Wistar rats. A total of twenty male Wistar rats where divided into four groups: (Group I. 150 mg/kg eugenol; Group II, 5 mg/kg FA; Group III, 150 mg/kg eugenol + 5 mg/kg FA; Group IV/control, 2ml/kg distilled water) for thirty days. FA and eugenol were administered orally. Rats were humanely sacrificed under 0.8 mg/kg ketamine anaesthesia administered intraperitoneally. Cognitive tests using Morris water maze and Novel object recognition test were carried out, Oxidative stress parameters, acetylcholine activity and histometric analysis of hippocampal Cornu Ammonis (CA 1 and 3) pyramidal neuronal cells. Administration of FA resulted in significant (p<0.05) increased activity of malondialdehyde (MDA), intra-mitochondrial accumulation of 8-hydroxydeoxyguanosine (8-OHdG), reduced activity level of superoxide dismutase (SOD) and acetylcholine levels. However co-administration of eugenol and FA resulted in significant (p<0.05) enhancement of cognitive ability and also significantly (p<0.05) reduced MDA and 8-OHdG levels, and increased SOD and acetylcholine levels. Our results indicate that eugenol would provide therapeutic value against FA induced oxidative stress and cognitive impairments.

The present investigation was carried out to evaluate the hepatoprotective effect of probiotic fermented milk (FM) containing Lactobacillus rhamnosus GG and Lactobacillus casei strain Shirota, alone as well as in combination with chlorophyllin (CHL) as an antioxidant agent in male Wistar rats administered aflatoxin-B1 (AFB1). AFB1 was injected intraperitoneally at the rate of 450 μg/kg body weight per animal twice a week for 6 weeks, maintaining an equal time interval between the two consecutive AFB1 administrations. A total of 125 male Wistar rats were randomly allocated to five groups, each group having twenty-five animals. Group I was offered FM containing L. rhamnosus GG and L. casei strain Shirota. Group II was administered AFB1 and served as the control group; group III was administered FM-AFB1, in which besides administering AFB1, FM was also offered. Group IV was offered CHL and AFB1, and group V was offered both FM and CHL along with AFB1. The rats were euthanised at the 15th and 25th week of the experiment and examined for the biochemical and hepatopathological profile. A significant reduction in thiobarbituric acid-reactive substances (TBARS) was observed in the FM–CHL–AFB1 group compared with the AFB1 control group. FM alone or in combination with CHL was found to show a significant (P < 0·05) hepatoprotective effect by lowering the levels of TBARS and by enhancing the activities of antioxidant enzymes such as glutathione peroxidase, superoxide dismutase, catalase and glutathione-S-transferase, indicating that probiotic FM alone or in combination with CHL possesses a potent protective effect against AFB1-induced hepatic damage.

The effect of concurrent exposure of toxic concentrations of lead and endosulfan were evaluated on oxidative stress parameters in male wistar rats. Group I served as untreated control whereas Group II received drinking water containing lead as lead acetate @1000 ppm (Pb1000). Group III was exposed to feed containing technical grade endosulfan @ 100 ppm (E100). Group IV was exposed to Pb (1000) +E (100). All the treatments were given daily for 28 days. Combination of lead and endosulfan modified the indices of oxidative stress in the parameters such as lipid peroxidation, reduced glutathione, superoxide dismutase and catalase in rats as compared to their individual compounds. The results suggest that the combination of these individual compounds may have the potential to modify oxidative stress produced by single compounds in male rats

Abstract Introduction: AAzathioprine and Methotrexate are both used in the treatment of cancer; and are classified as cytotoxic drugs with reported adverse effects such as oxidative damage to the DNA/RNA, the testes and sperm cells. This study, therefore, tested the hypothesis that AAzathioprine and Methotrexate administrations impair the morphology and functions of the testes in adult male wistar rats. Methods: AAzathioprine (50-150mg per day) and Methotrexate (2.5mg per week) are used in the treatment of cancer in adult Man. We tested the hypothesis that AAzathioprine and Methotrexate impair the morphology and functions of testes in rats. Forty adult male wistar rats (150-230g) were employed in the study: Control Group I received physiological saline while Experimental Groups II - V received oral administrations of 5mg/kg/bodyweight of AAzathioprine per day, 15mg/kg/bodyweight of AAzathioprine per day, 8mg/kg/bodyweight of Methotrexate per week and 20mg/kg/bodyweight of Methotrexate per week respectively for 35 days. Results: Histological examinations of the testes of rats of Groups II - V showed dose-dependent morphological anomalies such as fewer collagen ibers of connective tissues, disrupted seminiferous tubules and scanty spermatozoa when compared to rats of Group I. Statistical analyses showed dose-dependent elevated levels (P≤0.05) of superoxide dismutase and malondialdehyde in testes homogenates of rats of Groups II - V when compared to rats of Group I. This implied increased oxidative stress in rats of Groups II - V. Evaluations of Follicle Stimulating Hormone and Testosterone showed dose-dependent significantly elevated levels (P≤0.05) in rats of Groups II - V when compared to rats of Group I. Conclusions: Our findings are consistent with the stated hypothesis.
