title: Changes in contractile activity of the duodenum, jejunum, and ileum under conditions of psychogenic stress in rabbits.
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.
