[Gastric secretory function and the energy component of the mixtures used in parenteral feeding]

Experiments on dogs with a gastric fustula and Pavlov's (miniature) isolated pouch, kept on a high-standard mixed ration evidenced that intravenous administration of various substances acts on the fundal gastric glands differently. Some of such substances stimulate the secretion of an acid gastric juice (xylitol and ethyl alcohol), while others are inert in this respect (sorbitol, 1.2-propandiol, 1.3-butandiol, fatty intralipid emulsion). Five percent solutions of glucose and fructose do not provoke any significant secretion of juice, although also lead to a short-lived pH fall in the gastric secretion. At the same time the action of the said substances is markedly less intensive than the caseine hydrolysate (TSOLIPK) has an effect on the gastric juice. In the practice of parenteral nutrition with the preparation of nutrative mixtures the ability to provoke the gastric secretion by the ethyl alcohol and xylitol an account should be taken of.
