摘要: Cadmium (Cd) is a well-known nephrotoxicant inducing kidney damage via oxidative stress. Since the critical target organ of Cd toxicity, this study was designed to evaluate protective effects onion (Allium cepa L.) and garlic sativum aqueous extracts on Cd-induced renal stress in male Wistar rats. The control group received double distilled water alone challenged with 3CdSO4 · 8H2O (as Cd) (1.5 mg/100 g bw/day per oral) alone. Extract-treated groups were pre-treated varied doses (0.5 ml 1.0 ml/100 g bw/day and/or extract for 1 week after which they co-treated (1.5 mg/100 g bw/day 3 weeks. results showed that levels lipid peroxidation (LPO) glutathione-S transferase (GST) significantly (P < 0.001) increased rats relative group. More so, glutathione (GSH), superoxide dismutase (SOD), catalase (CAT) Na+/K+-ATPase decreased Treatment Cd-intoxicated (P < 0.05) restored alterations these parameters While treatment high dose exerted significant dose-dependent restoration parameters, elicited pro-oxidant effect, their respective low dose. Our suggests may exert reduction LPO enhanced antioxidant defense. These may, therefore, be useful nutritional option alleviating damage.
