Abstract:
OBJECTIVETo elucidate the difference between uterus body and cervix under the intervention of Shenghua decoction, and to observe the rabbit uterine muscle in the latest period of pregnancy for the way of myoelectric activity.
METHODPowerLab/8s was used to record myoelectric activity of rabbit muscle in uterus body and cervix which was in a general anaesthesia state induced by urethane.
RESULTMyoelectric activities of rabbit uterine smooth muscle in the latest period of pregnancy was enhanced in vivo by being treated with Shenghua decoction 40 mg x kg(-1) (P < 0.01) while cervix myoelectric activities had no significant change (P < 0.05).
CONCLUSIONMyoelectric activities of rabbit uterine muscle in the latest period of pregnancy are enhanced by being treated with Shenghua decoction so its hemostatic effect can be represented via the constriction of uterus body. Shenghua decoction is beneficial for child delivery because cervix myoelectric activities have no significant change under the intervention of Shenghua decoction while the myoelectric activities of uterus body are increased significantly.
