Abstract

The electrophoretic patterns of the proteins of the gastric juice of a series of patients with gastric ulcer, a control group, and a group of patients with miscellaneous gastric and systemic diseases were studied, autodigestion being prevented by maintaining the pH of the gastric contents above 7.

A slow moving anodal band (band 2) was present in 50% of the observations on gastric ulcer patients, whereas this band was present in only 10% of the patients who did not have a gastric ulcer.
