The effect of antihypertensive therapy on abnormal leucocyte sodium transport in essential hypertension

Abstract

Sodium transport in leucocytes of essential hypertensives was studied in physiological media. Untreated hypertensives have depressed values for the total and ouabain-sensitive sodium efflux rate constant. Treatment with diuretics abolished this abnormality. These results are compatible with the presence of a circulating inhibitor of sodium transport in essential hypertension.
