OBJECTIVE The purpose of this study was to investigate the contribution of potential-operated calcium (POC) channels in the mechanisms of the blunted effects of vasoconstrictors on mesenteric resistance arteries during normal pregnancy. METHODS Mesenteric resistance arteries of virgin and term pregnant rats were set up under optimum passive tension in wire myograph systems. Cumulative concentration-response curves of arginine8-vasopressin (AVP) were measured in the absence and presence of… CONTINUE READING
