title: [Morphological manifestations of anthracycline cardiomyopathy in the ventricular myocardium of the rat].
abstract: Cardiomyopathy and plastic contractile myocardial insufficiency were simulated in Wistar rats by an anthracycline antibiotic rubomycin. The myocardium in conditions of DNA-dependent RNA synthesis suppression was studied using polarization, electron microscopy and the method of cardiomyocyte isolation. During anthracycline cardiomyopathy in the absence of necrotic and necrobiotic myocardial injuries there was a smaller depression of cardiomyocyte population and their nuclei in the right ventricle (23 and 22% respectively) than in the left ventricle (38 and 39% respectively). It was concluded that a smaller amount of cardiomyocyte population was in the phase of intensive protein synthesis in the right than in the left ventricular myocardium.
