[The serum content of gastrin-17 and pepsinogen-1 in patients with duodenal ulcerative disease in occupational contact with nitrogenous compounds].

The levels of serum gastrin-17 (G-17) and pepsinogen-1 (P-1) were studied in 54 patients with duodenal ulcerative disease (UD) who worked at chemical plants manufacturing nitrogenous compounds and in 15 healthy individuals (a control group). There are objective data on the time course of changes in the functional characteristics (G-17 and P-1) of the gastric mucosa (GM) in the patients with duodenal UD, which vary with the chemical compositions of hazardous substances and the length of service at a chemical plant. Basic therapy for UD causes positive changes in the functional parameters reflecting the state of GM.
