The surface ultrastructural changes accompanying membrane retrieval in amphibian bladder tissues following removal of the hormone mezerein (MZ) are investigated. An apparent membrane internalization process using SEM following withdrawal of vasopressin (ADH) is reported. The time-response surface studies of the apical membrane internalization process following withdrawal of MZ is presented. Observations suggest that mezerein can mimic the actions of ADH in the induction of surface changes indicative of endocytosis. Further, these observations suggest that the protein Kinase C may participate in the overall process of cycling of water channels in toad urinary bladders.
