Abstract
Urea is accumulated in considerable amounts (>100 mM) in the blood of the euryhaline toadBufo viridis, under conditions of adaptation to high salinities. Salt adaptation increases active transport of urea (inward direction) in the skin, which was measuredin vitro. The active transport of urea is insensitive to ADH, and was inhibited nearly 50% by 0.5 mM phloretin. This transport system is different from the facilitated diffusion of urea which has been studied extensively in the toad urinary bladder, and may offer a simple model system for the study of active urea transport.This publication has 8 references indexed in Scilit:
