摘要
研究促性腺激素及类固醇激素对家兔小肠平滑肌功能的影响.取家兔离体小肠平滑肌十二指肠、空肠、回肠的不同肠段,分别置于灌流肌槽中,连接张力传感器,信号输入BL-420E+生物技能实验系统,加入促性腺激素、类固醇激素,分别记录小肠平滑肌的收缩活动.结果表明,促性腺激素可以增大十二指肠和回肠的收缩活动力,减小空肠的收缩活动力;孕酮可以减小十二指肠和回肠的收缩活动力,增大空肠的收缩活动力;雌二醇可以增大十二指肠和空肠的收缩活动力,减小回肠的收缩活动力.不同类型的生殖激素都能够影响家兔小肠平滑肌的收缩功能,影响方式依赖于激素及肠段类型.
This article is to research the influence of gonadotropins and steroid hormone on rabbit small intestines smooth muscle function.The authors took 3different intestinal segments of rabbit's detached small intestine smooth muscle:the duodenum,jejunum,and ileum,put them into the muscular perfusion slot,connected tension sensor,input the signal of BL-420E+biological skills experiment system,added the gonadotropins and steroid hormone to record each contractile activity of small intestines smooth muscles.The result shows that the gonadotropins can enlarge the contractile activity of duodenum and ileum and decrease that of jejunum;Progesterone can decrease that of duodenum and ileum and enlarge the jejunum's;Estradiol,however,can increase the duodenum and jejunum's contractile activity and decrease that of ileum.Reproductive hormones of different types can affect the contractile function of rabbit small intestines smooth muscle,and the way of influence depends on hormone and intestinal segment type.
