Background: To investigate the effect of Withania somnifera (WS) in preventing the damage caused by alcohol on testis. Methods: Adult male Wistar rats were divided into 4 groups. Group A-control, Group B-WS 200 mg orally, Group C-alcohol 4 g/kg orally, and Group D-WS + alcohol. The sperm parameters were examined. Testicular tissues were examined for biochemical (glutathione [GSH] peroxidase, superoxide dismutase, catalase (CAT), malondialdehyde [MDA]) analysis, and histopathological changes. Results: Biochemical parameters revealed tissue oxidative stress in alcohol group which was evidenced as increase in MDA level and reduction in CAT and GSH activities in testes which was reduced in co-treatment group. WS significantly reduced alcohol-induced sperm shape abnormality and sperm count. The alcohol-induced changes in histopathologic findings were partially reversed by treatment with WS. Conclusion: These observations suggest that the antioxidant property of WS might have contributed for its ability to ameliorate the testicular toxicity caused by alcohol.

The kidney is especially a susceptible organ to toxic injuries by drugs and toxin, because of a high blood supply and the presence of cellular transport systems that cause accumulation of these compounds within the nephron epithelial cells. Glomerular, tubular and interstitial cells frequently encounter significant concentrations of medications and their metabolites, which can induce changes in kidney function and structure. Renal toxicity can be a result of hemodynamic changes, direct injury to cells and tissue, inflammatory tissue injury and/or obstruction of renal excretion.Gentamicin is potent broad spectrum antibiotic therapeutic agent used in a number of infective conditions. Because of the obvious mediation of Reactive Oxygen Species in Gentamicin induced renal damage. Several antioxidant agents have been used to block Gentamicin nephrotoxicity.There is a proven converse relationship between the consumption of antioxidant rich plants incidence of human diseases. A primary goal of this study is to present the scientific evidence for the use of common herb Adhatoda zeylanica as supplementary in the gentamicin treated acute renal failure (ARF) subjects. The beneficial effect of A. Zeylanica against gentamicin nephrotoxicity, possibly depends on its ability to scavenge the gentamicin induced free radicals.This study demonstrates the effectiveness of the extract improved with the polarity of the solvents over a period of 10 days and the plant has the potential to ameliorate Gentamicin nephrotoxicity.

Objective:The objective of the study was to evaluate the nootropic activity of hydroalcoholic extract of Achyranthes aspera leaves using elevated plus maze and radial arm maze.Methods: Adult Wistar rats were allotted to three groups; Group 1 served as control, Groups 2 and 3 received 200 mg/kg and 400 mg/kg of AA extract, respectively, orally for 2 weeks after which the extent of improvement of memory was assessed.Results: AA showed nootropic activity in both elevated plus maze and radial arm maze. 200 mg/kg of AA extract showed better improvement in learning and memory compared to 400 mg/kg. Conclusions:These results indicate that AA leaves extract clearly exhibited the improvement in learning and memory.
