Erythrocyte Nai, Nai/Ki and ouabain-sensitive and ouabain-insensitive 86Rb uptake (K transport) were measured in whole blood of 16 normotensive and 19 hypertensive white male subjects, within seconds or minutes after withdrawal of blood. Erythrocyte Nai and Nai/Ki were reduced (p less than 0.05), and ouabain-sensitive 86Rb uptake was increased (p less than 0.01) in hypertensive subjects. In a separate group of hypertensive white male subjects, an inverse correlation was found between erythrocyte Nai/Ki and ouabain-binding sites per erythrocyte (r = 0.85, p less than 0.01, n = 9). The abnormalities of erythrocyte cation fluxes in hypertensive subjects are similar to those induced by aldosterone in vascular smooth muscle cells and by glucocorticoid administration in the erythrocytes of human subjects, suggesting similarities in pathogenesis.
