Takada et al., Am J Physiol 1996
:
The response to acetylcholine (ACh) can be used as a marker for larval-type bullfrog skin because apically applied ACh induces an increase in short-circuit current (SCC) in larval-type but not adult-type skin ... ACh , carbamylcholine, and choline stimulated SCC in skin that had been cultured with aldosterone ( 5 x 10 ( -7 ) M ) supplemented with prolactin ( PRL ; 2 micrograms/ml ) ... Atropine and d-tubocurarine each inhibited the ACh induced stimulation of SCC in skin so cultured

:
The short-circuit current (SCC) across the skin, far from being inhibited by amiloride, was stimulated by both amiloride and ACh
