摘要
To assess the role of endogenous neurotensin (NT) in the regulation of adrenocortical function, adult rats were given [D-Trp(11)]-NT, a specific NT-receptor antagonist (NT-A), subcutaneously, 4 nmol day(-1) for 7 days. NT-A raised the concentration of aldosterone in circulating blood, without affecting ACTH or corticosterone, and induced a marked hypertrophy of the zona glomerulosa. These effects of NT-A were reversed by the simultaneous administration of equimolar doses of NT. These results suggest that endogenous NT exerts a specific tonic inhibitory influence on the zona glomerulosa in rats.
