Evaluation of transport pathways for Na+ across frog skin epithelium by means of presteady-state flux ratio.

K Eskesen, J J Lim, H H Ussing.   

Abstract

A method is described that makes it possible to separate the sodium fluxes through the isolated frog skin into sets characteristic of the cellular and the paracellular pathway, respectively. If there are two significant pathways for the ion, and if they differ with respect to flux ratio as well as mean passage time, the flux ratios for the individual pathways can be obtained from a set of inward and outward tracer fluxes, covering the time from the addition of the tracers until the achievement of constant fluxes in both directions.
