[Gastric secretion study by maximal pentagastrin stimulation in healthy persons and peptic ulcer patients].

Gastric secretion was investigated in 187 subjects under conditions of maximal stimulation with pentagastrin. Thirty subjects, out of them, were healthy, 30--with gastric ulcer, 110--with duodenal ulcer and 17--with double ulcer localization--in duodenum and stomach. The indices of gastric secretion in duodenal ulcer and ulcer disease with double localization are considerably higher than those on the healthy subjects and differ essentially. With single gastric ulcer they are significantly lower than those of the healthy controls.
