[Gastric secretory function during enteral feeding].
Dogs with isolated Pavlovian pouches, a gastric fistula according to Basov, and a duodenal fistula were kept on enteral nutrition for 10 days. The nutritive mixture (35 kcal/kg bw) containing protein hydrolysates (2 g), fatty emulsion (2 g), and glucose solution with vitamins (2 g) was administered via a fistula to the intestine by drops daily for 8-9 h and gastric secretion was followed up. Enteral administration of the nutritive mixture stimulated gastric secretion whose intensity depended on the site and rate of its administration. The rate of juice secretion was the highest during administration to the duodenum. Less secretion was noticed during nutritive mixture supply to the jejunum. As the administration rate was raised, the secretion intensity increased. Gastric juice thus obtained was marked by high acidity and comparatively low pepsin concentration.
