本工作记录了家兔子宫肌电活动,观察了子宫起搏点的部位及电活动在子宫内的传导。通过12只产后1—3日家兔在体子宫的急性实验,结果表明:产后家兔子宫爆发放电从子宫输卵管端到宫颈端存在着频率梯度及其出现时相的规律性。爆发放电首先出现在近输卵管端且频率最高,随后依次出现在中间部及宫颈端且频率逐渐减低。因此,提示产后家兔子宫起搏点是存在的,其位于子宫的近输卵管端,电活动的传导从近输卵管端到宫端呈现衰减性变化。 This work recorded the rabbit uterine myoelectric activity, observed the site of uterine pacemaker and electrical activity in the womb conduction. The results of 12 acute postpartum rabbits’ in vivo uterus experiments showed that there was a regularity of frequency gradient and its appearance in the uterus from the end of the uterus to the end of the uterus. Explosive discharge first appeared near the end of the fallopian tube and the highest frequency, followed by turn in the middle of the cervix and the end of the frequency and gradually reduced. Therefore, suggesting that postpartum rabbit uterine pacemaker is present, which is located in the uterine proximal tubal end, the conduction of electrical activity from the proximal tubal end to the decay of the uterine end showed decay.
