From: Effect of phenylephrine and endothelium on vasomotion in rat aorta involves potassium uptake
Role of protein kinase G on K+ uptake in rat aortic rings. Endothelium-intact aortic rings with 10−7 M PE were pre-incubate in absence or presence of 10−4 M l-NNA (a), and endothelium-denuded aortic rings with 10−8 M SNP were pre-incubated in the absence or presence of 10−6 M KT-5823 (b). Aortic rings without endothelium were preincubated (10 min) with SNP. l-NNA was added 30 min before PE, and, when pertinent, KT-5823 was added 15 min in advance. *P < 0.05 and **P < 0.01 versus control, ## P < 0.01 versus PE, and $$ P < 0.01 versus SNP
