From: Effect of phenylephrine and endothelium on vasomotion in rat aorta involves potassium uptake
Effect of PE and ACh on K+ uptake in rat aortic rings. Intact aortic rings were incubated with PE alone (10−7 and 10−5 M) or ACh alone (10−6 and 10−5 M). The results are expressed as %K+ uptake versus control. The %K+ uptake was calculated as the ratio between total 86Rb uptake in absence or presence of vasoactive substances (control). **P < 0.01, *P < 0.05 versus 10−7 M PE or 10−6 M ACh, respectively
