Abstract
Some drug formulations containing digestive enzymes were shown to stimulate gastric and duodenal secretion owing to low-molecular-weight peptides (LMWPs) generated during isolation of the enzymes from raw biological materials. Similar LMWPs were found in gastric and duodenal ulcerous tissues. It was concluded that, transferred with the blood and the lymph, the LMWPs produced in such tissues continuously stimulate the exocrine function of the pancreas (probably, through a system of immunoreceptors). Persistent pancreatic hypersecretion results in functional failure of the gland and in chronic pancreatitis.
