Halothane inhibition of acetylcholine-induced relaxation in rat mesenteric artery and aorta.


PURPOSE The effect of halothane was compared on acetylcholine (ACh)-induced relaxation of the mesenteric artery and the aorta in rats. METHODS The responses of isolated rat aortic and mesenteric arterial ring segments precontracted with phenylephrine to ACh (10(-8)-10(-5) M), in the presence of halothane 0-3%, were compared using isometric force tension… (More)
