Abstract
The present study investigated the protective effect of melatonin on the tissue peroxidative damage in cyclophosphamide (CP) induced hepatotoxicity. Male albino rats of 250±20 gm were categorized into three groups. Two groups were administered CP (150 mg/kg/day intraperitoneally for 2 days) to induce hepatotoxicity; one of these groups received melatonin treatment (5 mg/kg intraperitoneally for 2 days 30 minutes prior CP administration). Group one served as the control. The extent of liver damage in CP-induced rats was evident from the increased activities of serum aminotransferases (ALT), alkaline phosphatase(ALP) and lactate dehydrogenase(LD); whereas melatonin pretreatment prevented the rise in these marker enzymes. Evaluation the changes of non enzymatic antioxidants glutathione along with malondialdehyde levels in the experimental groups. In CP-administered rats the antioxidant molecules showed depleted levels (p<0.05), in comparison with the control group. However the extent of lipid peroxidation and the abnormal antioxidant status were normalized in melatonin pretreated rats. Melatonin exerted cytoprotection towards liver organ at a dose of 5mg/kg/day. Histopathological examination also confirmed the protective efficacy of melatonin which may be efficacious as a hepatoprotectant in cyclophosphamide-induced liver toxicities.
