Effects of Cadmium on the Impedance Locus of the Abdominal Skin of the Bullfrog (Rana catesbeiana)

Abstract

An impedance locus consisting of two superimposed semicircular arcs was revealed on the abdominal skin of the bullfrog. The decrease of skin resistance upon epidermal application of Cd (2 mM), which was related to Na active transport, proved to be due solely to the reduction in the size of the high frequency arc.
