Evidence that acetylcholine-mediated hyperpolarization of the rat small mesenteric artery does not involve the K+ channel opened by cromakalim.
1. Acetylcholine causes a concentration-dependent hyperpolarization of the rat small mesenteric artery (diameter at 100 mmHg, 200-400 microns). In the absence of tone the average potential change was from approximately -60 to -75 mV. In the presence of tone induced by endothelin-1 (20 nM), acetylcho...
