UDC 611.08: 611: 611.12 + 611.16 morphology of contractile cardiomyocytes and vessels IN PREGNANT rats AND their pups exposed to HEMIC HYPOXIA I. V. Zadnipryany, O. S. Tret'yakova, T. P. Sataieva, W. Zukow Medical Academy named after S.I. Georgievskiy Federal State Autonomous Educational Institution of Higher Education "Crimean Federal University" Kazimierz Wielki University, Bydgoszcz Summary The performed morphological analysis of cardiomyocytes and myocardial vessels in 12 pregnant rats and 16 newborn pups exposed to the hemic hypoxia induced by NaNO2 revealed some similar degenerative and destructive changes which were more pronounced in pups. The main morphological characteristics of hypoxic myocardial damage in pregnant and newborn rats were presented in the form of phenomena of mixed dystrophy, swelling and destruction of endothelial cells and contractile cardiomyocytes along with the lysis of myofibrils, perivascular edema, capillary hyperemia, emptiness and spasm of the arterioles and contracture changes. Revealed pathological changes in the myocardium reflect the onset of myocardiodystrophy processes in pregnant rats and their newborn pups. Keywords: hemic hypoxia, cardiomyocytes, vessels, myocardium, pregnant rats, pups.
