[Gastric secretion of white rats with an experimental stress stomach ulcer].
The quantity of gastric juice, its acidity and enzymophoretic proteolytic fractions are evaluated in white rats with experimentally induced gastric stress ulcer. Stress ulcer in rats is caused by immobilization and cooling at 0 to 4 degrees C for a duration two hours. It is established that rats with experimental stress ulcers release an increased amount of gastric juice with normal acidity. In the gastric juice of healthy rats a proteolytic fraction is discovered, while in rats with experimentally induced stress ulcer of the stomach two and occasionally three proteolytic induced stress ulcer of the stomach two and occasionally three proteolytic fractions are found. In the discussion due consideration is given to the fact that some of the pathological fractions may play a certain causative role in the formation of gastric ulcers.
