Estradiol suppresses electrically-induced arterial thrombosis by increasing prostaglandin biosynthesizing activity of the aorta in rats

The anti-thrombotic effect of estradiol was studied using an electrically induced thrombus model in rats. Estradiol treatment significantly inhibited the thrombus formation induced by electric shock. In the meantime, a stimulation of prostacyclin biosynthesis by estradiol in aortas was found. This is the first report showing the correlation between the effects of the estradiol on the thrombus formation in an experimental model and on the prostacyclin production by aortas in the same animal system.
