Abstract
We have been studying the urinary bladder of the toad, Bufo marinus, as a model transporting epithelium which actively moves sodium from urine to body fluids [1, 2]. The results of two recent studies, which relate to the functional structure of this tissue and to how itspermeability properties are modified by vasopressin, will be presented.
Supported in part by grants from the John A. Hartford Foundation, Inc, and by the United States Public Health Service, research grants HE-06664 from the National Heart Institute and AM-04501 from the National Institute of Arthritis and Metabolic Diseases.
Work performed during tenure of a USPH Service Special Fellowship (1-F 3HE-18, 528).
