title: [Electron probe microanalysis of the potassium and phosphorus content in cytoplasm of cardiomyocytes of pregnant rats after an acute hypoxia incident].
abstract: The concentration of the elements (K, P) in the cytoplasm of rat (Wistar) cardiomyocytes has been determined by the electron probe analysis. The intracellular content of potassium and phosphorus was determined in early organogenesis and in unfertilized animals. In pregnant animals, a decrease in the cytoplasmic concentration of phosphorus and an increase in the concentration of potassium were registered. It was shown that the acute hypobaric hypoxia changes the content of both elements in the cytoplasm. The data obtained are discussed in terms of the activation of the ion transport system, which is aimed at compensating the cellular acidosis and lactosis induced by the development of hypoxic deenergization in pregnant animals.
