摘要：
The effect of the angiotensin-converting enzyme inhibitor, captopril, on Na+/H+-exchange activity and on Ca2+-ATPase mediated Ca2+-efflux was investigated in red blood cell membranes of patients with essential hypertension. The erythrocyte Na+/H+-exchange rate was measured as the difference in H+-efflux rate when measured in the presence or absence of Na+. The erythrocyte Ca2+-transport. mediated by Ca2+-ATPase was assayed as the erythrocyte Ca2+-efflux rate. Our data show that captopril, in vitro and in vivo, inhibits the Ca2+-ATPase mediated Ca2+-efflux rate in human erythrocytes, while in vivo it stimulates the erythrocytes Na+/H+-exchange rate.
