Escape from tension induced by noradrenaline or electrical stimulation in isolated mesenteric arteries.
Isolated mesenteric arteries, studied under 25-30 mg resting tension, responded to prolonged noradrenaline or electrical stimulation with a 50-500 mg increase in tension from which they subsequently escaped towards resting tension levels.
