    Abstract:
    A prolonged infusion with ANF (20 micrograms/kg/h for 7 days) induced atrophy of zona glomerulosa cells and lowering of basal plasma concentration of aldosterone in rats whose hypothalamo-hypophyseal-adrenal axis and renin-angiotensin system had been interrupted by the simultaneous administration of dexamethasone/captopril and maintenance doses of ACTH/angiotensin II. Chronic ANF treatment also caused comparable reductions in the aldosterone response of zona glomerulosa cells to the acute stimulation with angiotensin II, potassium and ACTH. These data are interpreted to indicate that ANF exerts an inhibitory effect on the growth and secretory activity of rat zona glomerulosa, and that the mechanism underlying this action of ANF does not involve blockade of renin release or ACTH secretion.
