title: Effects of Ag+ on frog skin: interactions with oxytocin, amiloride and ouabain.
abstract: Different biological effects of Ag+ (10(-4) M) were found depending on its presence in the outer or the inner solution bathing the frog skin. A marked increase in the electrical conductance and an interference with the action of oxytocin and amiloride were found only when Ag+ was added to the outer solution. Results suggest that Ag+ affects several transport processes, in particular the permeability of the Na entry pathways.
