[Angiotensin II-acetylcholine interaction on the mechanical response of the isolated rat stomach].
This research was carried on denervated isolated rat stomach. Mechanical response to Ach treated with three different ATN II concentrations was recorded. No competitive antagonism was observed so that no common receptor can be supposed. The apparent noncompetitive antagonism may be ascribed to the action of ATN II on P and T Ca++ activating systems.
