Effect of acute hypoxia on the concentrations of potassium and phosphorus in the cardiomyocyte of a pregnant animal during early organogenesis.
The concentrations of potassium and phosphorus in the cardiomyocyte cytoplasm of the Wistar rat were measured by means of electron probe microanalysis. Pregnancy was accompanied by a decrease in cytoplasmic phosphorus concentration and an increase in cytoplasmic potassium concentration. Acute hypoxia modified the concentrations of these elements in the cytoplasm.
