Fig. 3From: Effect of phenylephrine and endothelium on vasomotion in rat aorta involves potassium uptakeRepresentative recordings of vasomotion to PE in intact aortic rings. The vascular tissue was pre-incubated in a KRB buffer without calcium for 10 min before PE was added; and then, the KRB buffer was changed by normal KRB buffer to account for the experiment. The arrows indicate when the 10−7 M PE or Ca2+ (0.1–1.0 mM) was added to the bathBack to article page
