[Quantitative changes in gastric juice proteases in dogs during ulcer formation in the stomach].
Disc-electrophoretic investigation of proteases of the gastric juice of dogs under normal conditions and in experimental atophan ulcer of the stomach demonstrated that in fasting dogs ulceration was accompanied by marked quantitative changes in the protease spectrum. Fraction No. 6 showed a significant elevation against the background of total reduction of proteolytic fraction of the gastric juice in sham feeding of ulcerated dogs. Sham feeding replete ulcerated dogs indicated a marked increase of fractions No.1 and No.2. The noted changes of the gastric juice protease spectrum may be of ulcerogenic significance.
