Vasopressin increases bulk water flow across the toad bladder. To resolve whether this flow proceeds primarily between or through the surface epithelial ceils, the maximum intercellular flow rate was calculated. Since the experimental flow rate is 28 times the calculated maximum, bulk water flow is
## Abstract Because melatonin mimics the effects of microtubular disruptive agents (e.g., colchicine) in various cellular systems, we have examined its effect on water transport in the toad urinary bladder. Microtubules are essential to vasopressinβstimulated water transport in this tissue and are
