A technique is described fro measurement of rate of fluid reabsorption in a segment of the rat cauda epididymidis in vitro. The basal rate was 2-63 +/- 0-22 mul/cm2/30 min and was dependent on temperature and inhibited by 2,4-dinitrophenol, suggesting that fluid reabsorption is an energy-dependent process. About 50% of the fluid reabsorption was dependent on intraluminal sodium ions. This Na+-dependent component was inhibited by addition of amiloride to the intraluminal fluid and ouabain to the peritubular fluid.
本文描述了一种体外测量大鼠附睾尾段液体重吸收速率的技术。基础速率为2.63±0.22微升/平方厘米/30分钟，且依赖于温度，并受到2,4-二硝基苯酚的抑制，这表明液体重吸收是一个能量依赖过程。约50%的液体重吸收依赖于管腔内的钠离子。向管腔内液体中添加氨氯吡脒以及向管周液体中添加哇巴因可抑制这种依赖钠离子的成分。
