Endothelium-dependent contractions of isolated veins can be induced with arachidonic acid and thrombin. Anoxia causes endothelium-dependent contractions in a variety of isolated arteries and veins. Rapid stretch and acetylcholine contract cerebral arteries with, but not those without endothelium. Acetylcholine (and serotonin) cause endothelium-dependent contractions in the aorta of the spontaneously hypertensive, but not that of the normotensive rat.

1 Acetylcholine and angiotensin elicit a contraction of guinea-pig ileum. The metabolic requirements for these actions have been investigated.2 The angiotensin-induced response was far more dependent upon the presence of glucose than was the response to acetylcholine.3 Anoxia and oxidative enzyme inhibition preferentially reduced the angiotensin-induced response.4 The significance of these results is discussed. It is concluded that the response to angiotensin is dependent upon an ATP source distinct from that required by the contractile process. It is further shown that this energy-dependent stage cannot be identified with the indirect, cholinergic component of the angiotensin response in this tissue.
