Abstract
Melatonin in low doses of (0.05 and 0.5 mg/kg) administered to senescent rats in winter and summer inhibited free radical oxidation and LPO. The antioxidant effect of melatonin increased with increasing the dose of the hormone. Changes in test parameters were more pronounced in winter, but the directionality of changes did not depend on the duration of the light period.
