[Effects of qualitatively different food on acidity and proteolytic activity in different parts of the stomach of patients with duodenal ulcer].
Using an original technique, the authors studied acid-proteolytic activity in the stomach at night in 44 patients with duodenal ulcer before and after 12-h fasting; after meat, starch gel, vegetable oil meals. It was found that long-term fasting does not result in changed acid-proteolytic activity in the stomach body, though reduces a mean acid concentration in the stomach antral-pyloric portion 2-fold. Proteins and carbohydrates do not influence the acidity and produce multidirectional action on proteolytic activity of the stomach content: proteins inhibit, but carbohydrates enhance proteolysis. Vegetable oil results in a moderate decrease of the acidity.
