[Effect of acetylcholine on the tail artery reaction in rats].
The response to acetylcholine (10(-5) g/ml) was studied on the rat tail artery perfused with Krebs buffer. Perfusion with acetylcholine produced vasodilation (by 69%) in arteries pre-constricted with transmural nerve stimulation. Atropine (10(-6) g/ml) blocked more than 95% of this response. Acetylcholine had a vasodilating effect on arteries pre-constricted with norepinephrine.
