Abstract

Psychogenic stress in rabbits caused by fixation of the animal to a frame was accompanied by an increase in duodenal contractile activity. In the jejunum, initial inhibition of motor activity gave way to activation more pronounced in the proximal part. In both parts of the ileum, inhibition of contractile activity was noted. A proximodistal gradient of the excitatory and inhibitory effects on the motility of the small intestine was demonstrated.

摘要

将兔子固定在框架上所引起的心理性应激伴随着十二指肠收缩活动的增加。在空肠中，最初的运动活动抑制被近端更明显的激活所取代。在回肠的两个部分，均观察到收缩活动受到抑制。证实了对小肠运动的兴奋和抑制作用存在近端至远端的梯度。
