Sodium transport inhibition by amiloride reduces basolateral membrane potassium conductance in tight epithelia.

C W Davis, A L Finn.   

Abstract

In toad and frog urinary bladder, electrophysiological data suggest that inhibition of transepithelial sodium transport by mucosal amiloride results in a decrease in basolateral membrane conductance. These results were confirmed by showing that amiloride addition caused a decrease in basolateral membrane potassium permeability.
