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.
本文描述了一种方法，该方法能够将通过离体蛙皮的钠通量分别分离为细胞途径和细胞旁途径所特有的通量集。如果离子存在两条重要途径，并且它们在通量比以及平均通过时间方面存在差异，那么可以从一组内向和外向示踪剂通量中获得各个途径的通量比，这些通量涵盖了从添加示踪剂到双向达到恒定通量的时间段。
