Abstract:

1. 1. Sudden decreases in the osmotic gradient across the skin due to the replacement of water of the bath by 115mM NaCl had no effect on water uptake of intact or hypophysectomized toads. 2. 2. A concomitant decrease in the urine production was observed in intact but not in hypophysectomized animals. 3. 3. Addition of amiloride chlorydrate (0.25 mM) to the 115mM NaCl bath induced a significant decrease in water uptake both in intact and in hypophysectomized toads. 4. 4. The osmotic permeability coefficient (LPD) increased significantly during the osmotic gradient reduction with 115mM NaCl plus 0.25mM amiloride or 230 mM sucrose in both groups. 5. 5. No changes in the plasmatic osmolarity were detected during the development of these responses to the osmotic gradient reduction. 6. 6. These results are consistent with the hypothesis of short-term changes in the natripheric and hydrosmotic fluxes of water across the skin and in urine production triggered by the osmotic gradient reduction. The possible participation of arginine vasotocin in these responses is discussed. © 1987.
