摘要
The rate of free-radical oxidation in rat heart with experimental hyperthyroidism (EH) was estimated after Melaxen and Valdoxan administration. It was found that the content of protein carbonyl groups increased if the pathology developed in cardiomyocytes. This indicated that they were oxidized. Increased concentrations of primary lipid peroxidation products (diene conjugates), inhibition of aconitate hydratase activity, and accumulation of citrate were noted. Injection of Melaxen and Valdoxan to rats with EH normalized these parameters. The melatonin-correcting capability of the used drugs and the antioxidant activity of melatonin probably facilitated normalization of free-radical homeostasis in rat cardiomyocytes with the pathology.
