  Background: Neurohormone-regulated peripheral vascular resistance is considered one of the factors governing blood pressure. This study was designed to evaluate the effect of Arginine Vasopressin (AVP) on contraction of endothelium-intact or denuded rat aorta and mesenteric resistant arteries. Method: The wire myograph technique was used to assess the contractility of the vascular smooth muscles in response to a high-K+, phenylephrine, AVP and inhibitors, etc. The time-course of agonist-evoked contraction was then recorded. The endothelium of the mesenteric resistance arteries and abdominal aorta were denuded by physical abrasion, as evidenced by acetylcholine-induced vasodilation dysfunction. Results: The result revealed that: (1) AVP, but neither high K+ nor phenylephrine, evoke.. View more»
