Abstract：
:The effects of various vasodilators on the uterine vascular bed were investigated in nonpregnant, oophorectomized sheep with chronically implanted flow probes and catheters inserted into branches of the uterine arteries. A 1 mug dose of estradiol-17beta (0.224 muM) produces a maximum uterine blood flow response after intra-arterial injection. Adenosine (24 muM) and bradykinin (0.02 muM) were observed to increase blood flow to levels achieved by 1 mug of estradiol-17beta. Acetylcholine, isoproterenol, and histamine were less potent in their vasodilator activity. Atropine, propanolol, and diphenhydramine did not inhibit the increase of uterine blood flow induced by estrogens.

abstract：OBJECTIVE:Placental lipid peroxides and thromboxane are abnormally increased in preeclampsia. Thromboxane is a potent vasoconstrictor of the placental vasculature.
