Summary
Diamide, a thiol-oxidizing agent, blocks cAMP-mediated stimulation of Na and water transport when added to the outer solution bathing frog skin. No inhibition was found with diamide in the inner solution. These effects may be due to a perturbation of the thiol-disulfide status of specific components of the outer membrane of the epithelium.
