title: [The role of thyroid hormones in prevention of disorders of myocardial contractile function and antioxidant activity during heat stress].
abstract: The stress of heat under conditions of immobilisation induced an obvious depression of the cardiodynamic parameters. This correlated well with intensification of lipoperoxydation and a drop in the myocardial antioxydant activity. Small doses of thyroid hormones prevented the decline of the parameters, normalisied myocardial free-radical homeostasis in result of activation of superoxyddysmutase, catalase, and general antioxydant activity.
