[目的]研究十二指肠和空肠内注入大建中汤对消化道收缩运动的影响。[方法]在5只实验动物(犬)肠道的4个部位(胃窦部、十二指肠、近端空肠、远端空肠)分别缝合放置应力传感器,用于测量肠道收缩运动,十二指肠和近端空肠内留置用于注入大建中汤的硅胶管,在实验动物清醒情况下,向十二指肠和近端空肠内注入不同剂量的大建中汤,观察消化道收缩运动变化,并进行统计学处理。[结果]在十二指肠和空肠内注入大建中汤后,注入部位及远端肠道发生了收缩。[结论]大建中汤能促进消化道收缩运动。
[Objective] To study the effect of Dajianzhong decoction injected into the duodenum and jejunum on the contraction of digestive tract. [Method] Stresses were placed at 4 sites (gastric antrum, duodenum, proximal jejunum, distal jejunum) of 5 experimental animals (canine) respectively for measuring intestinal contractile movement, ten Into the duodenum and proximal jejunum indwelling large Jianzhong soup for silicone tube, in experimental animals awake, the duodenum and proximal jejunum were injected with different doses of large Jianzhong soup, observe the contraction of the digestive tract Exercise changes, and statistical analysis. [Result] After injecting Dajianzhong Decoction in the duodenum and jejunum, the contractions occurred in the injection site and distal intestine. [Conclusion] Dajianzhong decoction can promote the contraction of digestive tract.
