Angiotensin II Suppresses Water Absorption Through the Ventral Skin of Japanese Tree-Frogs in vitro.

We previously described two different water absorption systems in the ventral skin of the Japanese tree-frog, Hyla arborea japonica : i.e., a rapid enhanced flow, which is observed in dehydrated tree-frogs or those stimulated by adrenaline β-agonists or vasotocin, and a slow basal flow, which is observed in normally hydrated frogs during the non-breeding season. The rapid flow is completely blocked by ouabain, which has no effects on the slow basal flow. In the present experiment, we show that the vaso-constrictive hormone angiotensin II completely inhibits basal water absorption, but has no effect on rapid water absorption. These results confirm our previous finding that the two water absorption systems in the ventral skin of the Japanese tree-frog are independent of each other.
