Effect of Bradykinin and Acetylcholine on Renal Circulation in Hemorrhagic ShockExperimental Studies in Dogs with Cineradiography and Electromagnetic Flowmeter

摘要

NA;Renal arterial flow and venous washout time was studied in five anesthetized dogs during normotension and hemorrhagic hypotension. Cineradiography at 100 frames/sec was used, and flow measurements were made with an electromagnetic flowmeter directly applied to the renal artery. In hemorrhagic hypotension, acetylcholine and bradykinin caused an increased blood flow lasting 6 to 8 min after a direct injection into the renal artery.
