Abstract

The study was undertaken to find whether microinjection of vasopressin (AVP) into the rostral ventrolateral medulla (rVLM) affects blood pressure (BP) and blood viscosity in rats and to analyze the effects of AVP-ergic mechanism in the rVLM on stress-induced hyperviscosity of rats. The results suggest that the increase of BP and plasma viscosity induced by microinjection of AVP into rVLM and the stress-induced pressor response and hyperviscosity caused by restraining may be mediated by activation of the AVP V_(1) receptor in the rVLM.
