Introduction: Aluminium is most prevalent and third most abundant element in earth crust after oxygen. Its exposure in high concentration can accumulate in many organs that damage various organs in living organisms like humans and animals. Although aluminum (Al) is known to induce oxidative damage through various mechanisms including binding to negatively charged phospholipids on the membrane of various tissue cell which are rich in PUFA.Hence,this study was aimed to find the potential role of ashwagandha on aluminum induced testicular toxicity. Methods: Animals were segregated into 4 groups of 6 rats in each. The control group, the Ashwagandha treated group, the Aluminum intoxicated group, pretreated with Ashwagandha with Aluminum intoxicity group. Testicular tissue was removed and were stored in 10\% formalin saline and histopathological slides were done . A part of the tissues were processed for estimation of MDA and GSH level. Results: In the present study administration of aluminum in rats showed a significant decrease in the testicular tissue level of GSH and sperm count, as well as increase in the level of MDA and sperm morphology in aluminum treated group compared to normal control. Treatment with Ashwagandha showed a significant increase in testicular GSH level, sperm count and decrease in MDA level sperm morphology. Conclusion: The results of this study revealed that oral Aluminum Chloride administration induced adverse oxidative effects on the exposed animals and treatment with W. somnifera reduced the extent of aluminium chloride-induced tissue injury

Objective. To evaluate the antioxidant capacity and protective effect of aqueous and hydroalcoholic extracts of Senecio rhizomatus Rusby in rat erythrocytes subjected to oxidative stress with hydrogen peroxide (H2O2). Methodology. This study used an experimental design. The extracts were obtained through maceration with 96{\textdegree} ethanol (SeR96), 70{\textdegree} ethanol (SeR70), 50{\textdegree} ethanol (SeR50) and through infused water (SeRAc). Secondary metabolites were identified through colorimetric reactions and precipitation. In each extract, we could determine the capacity to eliminate 2,2-diphenyl-1-picrylhydrazyl radical (DPPH), the reduction of ferric ion and the total polyphenol content. In addition, the activity on the plasma membrane redox system (PMRS) was evaluated in each extract. The protection against oxidative stress in erythrocytes was evaluated by determining the content of reduced glutathione (GSH) and malondialdehyde (MDA). Results. Alkaloids, flavonoids, phenolic compounds, sesquiterpene lactones and sugars were identified in all the extracts. The total polyphenols content showed a correlation with the reduction of ferric ion (r=0.885) and with DPPH radicals elimination (r = -0.899), where the one with the highest antioxidant capacity was SeR50. Thus, the SeR50 (all concentrations) and SeR70 (100 μg/mL concentration) significantly increased the PMRS activity compared to the control group. After inducing oxidative stress in erythrocytes, all the extracts maintained the GSH level and inhibited MDA formation significantly compared to the H2O2 group. Conclusion. The antioxidant capacity of hydroalcoholic extracts (96{\textdegree}, 70{\textdegree}, 50{\textdegree}) and aqueous infusion of Senecio rhizomatus Rusby is related to the content of polyphenols. They increase the plasma membrane redox system activity in rat erythrocytes and protect them from oxidative stress induced with H2O2, showing an increase in the concentration of reduced glutathione and a decrease in malondialdehyde.
