[Lipolytic activity of the small intestine in patients with duodenal ulcer].
Aspiration biopsy of the mucosa from the beginning of the jejunum was conducted in 43 patients with duodenal ulcer (during exacerbation) and in 15 normal subjects (control group). The biopsy sample was used to study the jejunum activity in providing the initial stages of triglyceride hydrolysis in the area of membrane and intestinal digestion. Monoglyceride lipase activity of biopsy sample homogenate was studied that provided the final stages of triglyceride hydrolysis. As a result of histological investigations of biopsy samples from 34 patients, chronic jejunitis (without atrophy) was diagnosed in 32 of them. Increased lipolytic activity providing the initial stages of triglyceride hydrolysis in the area of intestinal and membrane digestion, and decreased production of monoglyceride lipase by the jejunum have been recorded.
