Abstract

In isolated intestine of the European Flounder, cyclic AMP and theophylline induce a reduction of the negative transmural potential difference and short circuit current, increase severalfold the passive permeability for chloride and abolish the active transport of this ion. These effects are very different from those described in mammals.

摘要

在欧洲比目鱼的离体肠段中，环磷酸腺苷（cAMP）和茶碱可导致跨壁负电位差和短路电流降低，使氯离子的被动通透性增加数倍，并消除该离子的主动转运。这些效应与在哺乳动物中所描述的效应有很大不同。
