Vasopressin causes dilation of the intercellular spaces of the mucosal epithelium in toad bladder, an effect previously thought to result from enhanced net transepithelial water transport. Under conditions of zero net fluid transport, vasopressin exerted the same effect in seven tissues, which indicates that the width of the intercellular spaces cannot be taken as a reliable index of net transepithelial fluid transport.
血管加压素可使蟾蜍膀胱黏膜上皮细胞间间隙扩张，这一效应先前被认为是由上皮细胞间液体净转运增强所致。在液体净转运为零的情况下，血管加压素在七种组织中产生了相同的效应，这表明细胞间间隙的宽度不能被视为上皮细胞间液体净转运的可靠指标。
