title: [Changes of catecholamine content in the myocardium in thyrotoxicosis].
abstract: Experimental thyrotoxicosis was induced in rats and rabbits. The content of catecholamines was significantly decreasing in the myocardium of rabbits in the presence of severe thyroidine-induced toxicosis. The noradrenaline concentration was especially low in the ventricles. The histochemical examination of the myocardium of rats revealed a reduction of catecholamines fluorescence, which indicates a decrease in their amount in the adrenergic structures.
