[Cyclic AMP and control of ion exchanges in the fish intestine].
In isolated intestine of the European Flounder, cyclic AMP and theophylline induce a reduction of the negative transmural potential difference and short circuit current, increase severalfold the passive permeability for chloride and abolish the active transport of this ion. These effects are very different from those described in mammals.
