Abstract

This study was designed to examine the effect of adrenal steroid hormones on the response of the toad bladder to vasopressin. Aldosterone enhanced the short-circuit current response, the osmotic water flow response, and the urea permeability response to vasopressin. Since aldosterone also enhanced the short-circuit current response and the osmotic water flow response to adenosine 3′,5′-monophosphate, the steroid effect on the bladder's response to vasopressin appears to be at a step beyond the stimulation of adenyl cyclase.
