we have analyzed the contractile response of rabbit aortic strips in response to maximal effective concentrations of the agonists norepinephrine , angiotensin ii and acetylcholine in the absence and presence of their specific antagonists : phentolamine , saralasin and atropine in order to determine the actions of the antagonists on these functional properties of vascular smooth muscle .
