[The effect of oxytocin on contractility of the human uterine artery]

We have studied in this work 30 human uterine arteries which were taken from hysterectomy specimens where the indication for the hysterectomy was obstetrical or gynaecological. The arteries were prepared in strips using furchgott and Bhadrakom's technique that they developed for the isolated aorta of the rabbit so that the authors could study the response to oxytocin on the isolated human uterine artery. When CIK was added to the preparation in which the arteries were, oxytocin had an antagonistic effect which was dose-dependent. The same effect was noted when Cl2Ba was added.
