Abstract We investigated the effect of aluminium phosphide exposure (10 mg/kg body weight) on lipid peroxidation and antioxidant defence system in different regions of rat brain. A significant increase in lipid peroxidation in cerebrum, cerebellum and brain stem was observed in aluminium phosphide-exposed rats, which was accompanied by a marked decrease in the activities of antioxidant enzyme, superoxide dismutase and catalase. A decline in the activity of glutathione reductase was also observed, however, no change was seen in the activity of glutathione peroxidase following aluminium phosphide administration. Decreased levels of non-protein thiols and total sulfhydryl groups were also observed after aluminium phosphide treatment. It seems evident that aluminium phosphide exposure significantly enhanced neuronal lipoperoxidative damage with concomitant alterations in the antioxidant defence status thus having serious bearing on the functional and structural status of the central nervous system.
