【 摘 要 】

BackgroundAcetaminophen (APAP)-induced toxicity is a predominant cause of acute hepatic and renal failure. In both humans and rodents toxicity begins with a reactive metabolite that binds to proteins. This leads to mitochondrial dysfunction and nuclear DNA fragmentation resulting in necrotic cell death. Pleurotus ostreatus (an edible oyster mushroom) is well recognized as a flavourful food, as well as a medicinal supplement. In the present study, we evaluated the role of Pleurotus ostreatus in the protection against APAP-induced hepato-renal toxicity. We also explored the mechanism by which Pleurotus ostreatus exerts its effects.MethodsNinety adult male Swiss albino mice were divided into three groups (30 mice/group). Mice were offered normal diet (control and APAP groups), or diet supplemented with 10% Pleurotus ostreatus (APAP + Pleurotus ostreatus) for 10 days. Mice were either treated with vehicle (control group, single intra-peritoneal injection.), or APAP (APAP and APAP + Pleurotus ostreatus groups, single intra-peritoneal injection, 500 mg/kg), 24 hours after the last meal.ResultsAPAP increased serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST) glutamate dehydrogenase (GDH), creatinine, blood urea nitrogen (BUN), urinary kidney injury molecule-1 (KIM-1), and hepatic and renal malondialdehyde (MDA) content. APAP decreased hepatic and renal glutathione (GSH) content, as well as glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) activities. Supplementation with Pleurotus ostreatus significantly reduced APAP-induced elevated levels of ALT, AST, GDH, creatinine, BUN, KIM-1and MDA, while GSH level, and GSH-Px and SOD activities were significantly increased. Our findings were further validated by histopathology; treatment with Pleurotus ostreatus significantly decreased APAP-induced cell necrosis in liver and kidney tissues.ConclusionsWe report here that the antioxidant effect of Pleurotus ostreatus opposes mitochondrial dysfunction and oxidative stress accompanying APAP over-dose, with subsequent clinically beneficial effects on liver and kidney tissues.
