COMPARATIVE CHARACTERISTICS OF QUALITATIVE CHANGES IN ULTRASTRUCTURES OF MYOCARDIAL EMBRYOS OF RATS IN NORMAL AND AFTER THE EFFECT OF ETHANOL IN DURING 1- TH-28-TH DAY OF POSTNOTAL ONTOGENESIS

Abstract
Qualitative changes in the ultrastructure of the ventricular myocardium of the embryos of the control group (normal) and the experimental (effect of ethanol) on the various stages of postnatal ontogenesis in normal and after the action of ethanol were compared in the article. For this study, methods of electron microscopy were used, with the help of which electronic micrographs were obtained. The analysis of the data showed significant differences in the ultrastructure of the contractile apparatus of cardiomyocytes during the early stages of postnatal feeding of rats. It has been established that alcoholic andoxication involves the contraction of sarcomers with subsequent fragmentation, disorientation of actin and myosin threads. The degree of violation of the ultrastructure of the cardiomyocytes of the experimental group depended on the period of postnatal development.
