[Variations in ATPase activities of erythrocytic membrane and endocytic ionic levels in cases with pregnancy induced hypertension].
The ATPase activities of erythrocytic membrane and endocytic ionic concentration were determined in 30 cases with pregnancy induced hypertension (PIH), 25 normal pregnancies and 20 non-pregnant controls. The activities of Na(+)-K(+)-ATPase and Ca(++)-ATPase were found significantly lower in PIH than those in the controls, but Mg(++)-ATPase activity revealed no Na+ and Ca++ values were significantly higher while Mg++ obviously lower in those with PIH than in the controls, and K+ was almost the same in the three groups. These findings suggested a close relationship between the pathogenesis of PIH and the abnormal ATPase activities and ionic levels.
