摘要：Angiotensin II stimulated 45Ca2+ release from bovine adrenal glomerulosa cells. It also decreased the influx of 45Ca2+ into glomerulosa cells. The effects were observed within 2 min of hormone addition and were blocked by Saralasin a competitive inhibitor of angiotensin. Des-Phe8-angiotensin II, a biologically inert analog, was inactive in this system. Angiotensin II also inhibited the influx of 133Ba2+ and 54Mn2+, whereas 51Cr6+ and 57Co2+ were unaffected. Alterations in 45Ca2+ fluxes were seen with concentrations of angiotensin that stimulate aldosterone biosynthesis in bovine glomerulosa cell preparations. These results suggest that calcium plays a key role in angiotensin-stimulated aldosteronogenesis.
