Endothelium-dependent relaxation induced by angiotensin II and histamine in isolated arteries of dog.

Abstract

In helical strips of dog renal and mesenteric arteries pre-contracted with prostaglandin F2 alpha (PGF2 alpha), endothelium-dependent relaxations were investigated. Removal of the endothelium was shown histologically by staining with silver nitrate and functionally by testing the inability of acetylcholine to induce arterial relaxations. When the endothelium was removed, relaxation of renal arteries to angiotensin (Ang) II was markedly suppressed, whereas relaxations induced by PGI2 or isoprenaline were attenuated only slightly. Removal of the endothelium attenuated the relaxant response of mesenteric arteries to histamine but did not significantly alter the response to PGI2. Treatment with indomethacin caused an additional attenuation of the relaxant response to histamine or a reversal of the Ang II-induced relaxation to a contraction in the arterial strips, from which the endothelium had been removed. Relaxation of renal arteries induced by Ang II and of mesenteric arteries induced by histamine is postulated to result from PGI2 released from the arterial wall. Therefore, it appears that the endothelium is a major site but not the only site responsible for drug-induced release of PGI2.
