To investigate the possible role of hormones in gastric mucosal protection, the effect of prostaglandin F2 beta, dimercaprol, or cysteamine on ethanol-induced gastric erosions, and of cimetidine on gastric erosions caused by aspirin was studied in intact, adrenalectomized, medullectomized, ovariectomized, or thyroidectomized rats. Cimetidine was administered at a low dose that did not inhibit hydrogen ion secretion. Adrenalectomized animals failed to exhibit the usual mucosal protective response to prostaglandin F2 beta, sulfhydryls, or cimetidine. Ovariectomy or thyroidectomy did not influence mucosal protection with these agents. The inhibition by total adrenalectomy of mucosal protection was not reversed by large intragastric doses or by parenteral administration of prostaglandin F2 beta. Adrenal medullectomy alone significantly diminished (by approximately one-third) ethanol-induced gastric mucosal injury; prostaglandin F2 beta or sulfhydryl drugs produced significant additional protection. Replacement therapy with glucocorticoids (triamcinolone, corticosterone) but not with mineralocorticoids (deoxycorticosterone, 9 alpha-fluorocortisol) restored the cytoprotective effect of prostaglandin F2 beta and sulfhydryls in adrenalectomized rats. The generation of prostaglandin E2- and prostaglandin I2-like activity in the gastric mucosa was unaltered by adrenalectomy. These studies suggest a permissive role for glucocorticoids in gastric mucosal protection induced by prostaglandins, sulfhydryls, and cimetidine.
