title: Calcium and sodium transport in gestational hypertension.
abstract: The enzymatic activities of Na+/K+ ATPase and Ca2+ ATPase were determined on erythrocyte membranes from 9 normotensive and 9 gestational hypertensive pregnant women near term. A reduction in the activity of the Na+/K+ ATPase and a relative increase in the activity of the Ca2+ ATPase were found in the hypertensive patients, possibly due to a conformational alteration of erythrocyte membranes. This observation supports the possible role of the transmembrane cation transport in the pathogenesis of gestational hypertension.
