[The role of antioxidants in the action of thyroxine on myocardial functional properties in rats]

Abstract

In conditions of excessive hormones in the blood, alpha-tocopherol increases the cardiomyocytes antioxidant defence, partially prevents the enhancement of the heart tissue sensitivity to induced peroxide oxidation of lipids, and considerably diminishes disorders in the heart contractile function. Under the same conditions, reduced glutathione no only does not exert its defensive action, but even decreases the heart resistance against hypoxia.
