When active Na+ transport across the toad urinary bladder was abolished by ouabain, a 'reversed' short circuit current could be induced by an Na+ concentration gradient. This reversed current was increased by vasopressin and inhibited by amiloride and appears to represent net Na+ movement 'backwards' through epithelial cells which normally participate in active Na+ transport across the bladder.
当哇巴因消除蟾蜍膀胱的主动钠转运时，钠浓度梯度可诱导出“反向”短路电流。这种反向电流会因血管升压素而增加，因阿米洛利而受到抑制，它似乎代表钠通过正常参与膀胱主动钠转运的上皮细胞“反向”净移动。
