Abstract
The cytoplasmic concentrations of elements (K, P) in the cytoplasm of rat (Wistar) cardiomyocytes have been determined by electron probe microanalysis. The intracellular content of potassium and phosphorus was determined in early organogenesis and in unfertilized animals. A decrease in the cytoplasmic concentration of phosphorus and an increase in potassium concentration were shown in pregnant animals. Acute hypobaric hypoxia was shown to change the cytoplasmic contents of both elements. The data obtained are discussed in terms of activation of the ion transport system aimed at compensation for cell acidosis and lactosis induced by development of hypoxic deenergization in pregnant animals.
