[Proteolytic enzymes of the gastric mucosa in the dog].
12 proteolytic fractions were obtained with disc--electrophoresis from the gastric mucosa in healthy dogs. 5 proteases (I group) were only found in fundus and gastric body whereas 7 those (II group) were found in antrum as well. Study of the fractions proteolytic activity revealed two of them to be active in pH 1.0-5.0; two in pH 4.0-5.0; one in pH 1.0-2.0; the area of other proteases activity involved 3-4 units of pH. The considerable amount of proteases and the large area of their activity seem to secure the protein hydrolysis in the stomach in different pH values of eaten food.
