Abstract
Ouabain at low concentrations was shown to stimulate the transport of Na+ in the isolated toad bladder as measured by the short-circuit current. At higher concentrations it inhibited the SCC. Increasing the K+ concentration to 14 mM antagonized the inhibitory effect of ouabain, but this higher level of K+ appeared to enhance slightly the stimulatory effect of a lower concentration of ouabain although the significance of the difference was statistically questionable.
