Malathion, widely used organophosphorus insecticide worldwide, induces oxidative liver damage type; cimetidine is an antagonist of histamine H2-receptor, it has been shown to be an inhibitor of various CYP45o isoforms. Male Wistar rats weighing 200-250 g were studied, exposed to malathion orally for 3 weeks （0.15 mg/kg/day, 2 mg/kg/day, 15 mg/kg/day） and cimetidine 10 mg/kg/day. Malathion plus cimetidine affect susceptibility to oxidative stress and possibly modifies the antioxidant defense capacity directly or indirectly.展开更多
