[Role of gastric mechanoreceptivity in formation of food satiety].
We have investigated the modulation of satiety in chronic experiments by stretching (different intensity and duration) stomach and duodenum with elastic intragastric balloon, filled with warm water on polifistuled (esophagus, gaster, duodenum) dogs. Estimation of periodical gastric motor activity was done by multiple determination of glucose concentration level in blood flow portions (blood tap method) towards and out of the brain, as well as liver. It appears that the signal conditioned by gastric stretching occurs to be the constant factor of formation and maintenance satiety condition for prolonged time.
