Influence of contractile agonists on the mechanism of endothelium‐dependent relaxation in rat isolated mesenteric artery

This study demonstrates directly that the relative contribution of nitric oxide (NO) and an NO synthase‐independent repolarization to acetylcholine‐evoked relaxation in rat isolated mesenteric resistance arteries is determined by the processes which mediate pre‐contraction. Noradrenaline‐induced con...
