Fig. 2From: Effects of different vasopressors on the contraction of the superior mesenteric artery and uterine artery in rats during late pregnancyContractile responses to uterotonic agents in rat uterine arteries and mesenteric arteries. Cumulative concentration-response curves to phenylephrine (10− 9 ~ 10− 4 M), norepinephrine (10− 9 ~ 10− 4 M), metaraminol (10− 9 ~ 10− 4 M), or vasopressin (10− 9 ~ 10− 5 M) were constructed. Contractile responses are shown as a percentage of KPSS (potassium depolarizing solution) maximum contractionBack to article page
