Comparison of mucus substances in gastric juice of normal subjects, duodenal ulcer and dyspeptic patients.

The sugar and nitrogen content of the gastric juice was assessed in 27 patients with duodenal ulceration, 17 patients with dyspepsia, and 27 normal volunteers. Comparing the data for each constituent for each patient using a discriminant function analysis, it was shown that the normal group differed significantly from both the duodenal ulcer group and the dyspeptic group, but that there was only a degree of variation between the two groups of patients.
