[The enzymatic activity of transmembrane ion transport in the early stages of hypertension].

A study is presented of the activity of Na(+)- K(+)-, Mg2(+)- and Ca2(+)-ATP-ases, lipid spectrum of the erythrocytic membranes and the content of intracellular sodium and potassium in 26 patients with borderline arterial hypertension (BAH) and 41 patients with hypertensive disease, stage I (HD). It was shown that these patients revealed an essential reduction of Na(+)-K+ATP-ase. The diagnostic and differential diagnostic value of these tests is discussed.
