Abstract

A net inward fluid reabsorption (salt-linked flow) has been observed in isolated skin epithelium (split skin) with the same magnitude as in whole skin when identical NaCl Ringer solutions were used to bathe both sides. Split skins also respond to a hyperosmotic sucrose solution bathing the outer (epithelial) surface by generating an outward osmotic flow. A non-linear relationship between osmotic flow and the osmotic gradient has been found in split skin similar to that found in whole skin.

摘要

当使用相同的氯化钠林格溶液同时冲洗隔离皮肤上皮（劈开的皮肤）的两侧时，观察到其存在净内向液体重吸收（盐相关流动），其程度与全皮相同。当用高渗蔗糖溶液冲洗劈开皮肤的外（上皮）表面时，劈开皮肤也会产生外向渗透流。在劈开皮肤中发现渗透流与渗透梯度之间存在非线性关系，这与在全皮中发现的情况类似。
