[In vitro evaluation of cutaneous potentials in the triton, Pleurodeles waltlii Michah., by measuring transepithelial potentials].
Surface potentials previously measured in vivo have been approximately evaluated in vitro by means of an experimental device allowing a simultaneous record of transepithelial potential differences in 2 areas of the same skin piece cut out along the proximo-distal direction of the anterior limb of Pleurodeles waltlii. These potentials are thus explained by unequal transepithelial potential differences in the proximal and distal areas of the same skin sample.
