ABSTRACT

Melatonin (MEL) was investigated for protection against the anthracycline antibiotic doxorubicin (Dox) that is well known for its oxidative damage to various body organs. It was aimed to have a comparison of this protection to heart, liver and kidney in the treated subjects. In this study, groups of mice were treated with Dox and melatonin and their individual or combined effects were evaluated by assessing lipidperoxidation, non-protein sulfhydryls (NP-SH) and nitrate/nitrite (NO) contents in these tissues. Plasma aminotransferases, LDH and CK-MB enzyme activities were measured. Moreover, these tissues were subject to histopathological assessment. MEL co-treatment significantly prevented any rise in lipidperoxides more significantly in heart and liver as compared to kidney. In tandem, MEL prevented a decline in GSH that was observed by Dox alone in liver and kidney. Dox significantly increased total NO levels in all the tissues. Melatonin at both dose levels could not afford protection against nitrosative stress. MEL in combination treatment provided significant (P < 0.01) decline in CK-MB at both the doses and only 5 mg/kg dose significantly prevented a rise in LDH activity and prevented any histopathological change. Melatonin, probably by behaving as an antioxidant prevented Dox-induced lipidperoxidation in heart, liver and kidney tissues and a decline in NP-SH. However, administration of MEL is able to decrease parameters of oxidative, and nitrosative stress in heart and liver more effectively than kidney.
