The urinary bladder of the tortoise, Damonia subtrijuga, acidified its mucosal surface and increased the pH at its serosal surface in vitro. 2. 2. Acetazolamide reduced this acid-base transport, apparently by reducing the H + or HCO 3 - available for transport. 3. 3. Betazole increased acid-base transport, apparently by increasing the H + or HCO 3 - available for transport, and by increasing the permeability of the mucosal epithelial cells. 4. 4. HCO 3 - at the mucosal surface increased, and at the serosal surface decreased, acid-base transport. © 1972.Mahidol UniversityBiochemistry, Genetics and Molecular BiologyArticleSCOPUS10.1016/0300-9629(72)90476-8
