[Structural-metabolic characteristics of the myocardium in acute hemorrhage and hyperbaric oxygenation].
Histochemical and pathomorphological changes in the myocardium in acute loss of blood and hyperbaric oxygenation were investigated in experiments on 130 white rats. It was established that acute loss of blood brought about an activation of phosphorylase, a decrease in the content of glycogen, an inhibition of the activity of cytochrome oxidase and succinic dehydrogenase in the myocardium. Foci of dystrophy were formed in the subendocaridal zone of the two ventricles and septum. Oxygenobarotherapy contributed to normalization of the level of activity of enzymes, preservation of glycogen, reduced the extent of manifestation of dystrophic changes in myocardiocytes. Hyperbaric oxygenation of healthy animals led to changes in the enzymatic activity in the myocardium. Dystrophic changes were noted in individual myocardiocytes. The data obtained testify to a direct influence of oxygen on metabolism of the myocardial cells.
