Contractile activity of gastroduodenal and ileocecal zones during stress in rabbits.
Chronic experiments on rabbits showed that stress modeled by immobilization in the supine position induced different motor reactions in the gastroduodenal and ileocecal zones. Stress inhibited contractile activity in the stomach antrum, distal ileum, ileocecal valve area, and proximal colon and stimulated it in the duodenum. In the pyloric portion of the stomach both the inhibitory and potentiating effects of stress were observed.
