title: Prophylactic action of melatonin against cyclophosphamide-induced oxidative stress in mice.
abstract: The present study investigated the prophylactic influence of melatonin against cyclophosphamide-induced oxidative stress in mouse tissues. Lipid peroxidation, reduced glutathione (GSH), glutathione disulphide (GSSG), glutathione peroxidase (GSH-Px) and serum phosphatase levels were analyzed in brain, spleen liver, lungs, kidney and testes. Fifteen days oral administration with melatonin (0.1 mg/kg bw per day) before treatment checked the augmentation of the level of lipid peroxidation, blood GSSG and acid phosphatase caused by an acute treatment with a radiomimetic drug, cyclophosphamide (75 mg/kg bw). Cyclophosphamide-induced depletion in the level of GSH, GSH-Px and alkaline phosphatase was made up statistically significant by chronic melatonin administration given orally. The results indicate the antioxidative properties of melatonin resulting into its prophylactic property against the cyclophosphamide-induced biochemical alterations. The finding support the idea that melatonin is a potent free-radical scavenger and antioxidant.
