Fig. 1. Effect of the addition of 10 µmol l-1 dopamine (DA) to
30
saline solution in isolated perfused posterior gills of
Chasmagnathus granulatus. (A) Time course of a representative
experiment. (B) Means plot. Dopamine significantly induces transepithelial
potential differences (Vte)
(*P<0.01; N=5). After 40-60 min of dopamine
application, Vte becomes not significantly different from
the control value.
