Beneficial effect of arginine vasopressin on hemorrhagic shock through improving the vascular reactivity

LI Tao, YANG Guangming, XU Jing, LIU Jiancang, LIU Liangming

Frontiers of Medicine 2008, Volume 2, Issue 3,   Pages 248-254 doi: 10.1007/s11684-008-0047-5

Abstract: The vascular reactivity and calcium sensitivity were decreased following hemorrhagic shock.Arginine vasopressin (AVP) was beneficial to endotoxic, infectious/septic and hemorrhagic shock.found that Rho kinase played an important role in the occurrence of calcium desensitization following shockSo we hypothesized that AVP might have beneficial effect on shock via activation of Rho kinase to regulateHemorrhagic shock (40 mmHg for 2 h) Wistar rats were adopted to observe the effects of small dose of
