Increased Na+ excretion by the skin of Rana pipiens after NaCl loading.
In vivo the frog skin excretes sodium and the sodium excretion is increased in response to a NaCl load. The sodium excretion can be demonstrated in vitro, and the rate of excretion is greater in skin from NaCl-loaded animals than from control, non-loaded animals. Unidirectional 22Na flux experiments on paired frog skins, as well as 22Na and 24Na bidirectional flux experiments measured in vitro, confirm the above finding that net sodium excretion occurs in response to the NaCl load.
