The effect of adrenal insufficiency on the plasma concentrations of two vasoactive hormones, vasopressin and angiotensin II, was studied in conscious dogs. In addition the role of vasopressin in the maintenance of blood pressure during adrenal insufficiency was studied using [1-(beta-mercapto-beta, beta-cyclopentamethylenepropionic acid),2-(O-methyl)tyrosine]arginine vasopressin, a specific antagonist of the vasoconstrictor action of vasopressin. Dogs were bilaterally adrenalectomized and maintained on daily cortisol and deoxycorticosterone acetate injections. Withdrawal of steroids for 4 days resulted in a 4-fold increase in plasma vasopressin concentration (P less than 0.05) and a 3-fold increase in plasma angiotensin II concentration (P less than 0.001); mean arterial pressure did not change significantly. Administration of the vasopressin antagonist in adrenalectomized dogs maintained on steroids had no effect on blood pressure. In marked contrast, vasopressin blockade in dogs with adrenal insufficiency decreased mean arterial pressure by 22 +/- 5 mm Hg (P less than 0.001). These results demonstrate the plasma angiotensin II and vasopressin concentrations increase during adrenal insufficiency in conscious dogs, and that vasopressin plays an important role in blood pressure regulation in this hypovolemic state.
