In the model of acute ulcers induced by acid ethanol, showing a protective effect of a dose-dependent α-LA and its tryptic hydrolyzate. Effect hydrolysates significantly higher than the native protein and is dependent on proteolytic exposure process. The most pronounced anti-ulcer effect in experiments with animals (rats) showed low molecular weight peptides derived from proteolysis long. Caused in an experimental model of acidified ethanol necrotic damage in the gastric mucosa was less or absent if the stomach 30 minutes before initiation of ulcers treated hydrolysates α-LA. The corresponding absolute patronage ulcer damage - the dose was for the native α-LA 280 mg / kg, for the most effective low molecular weight hydrolyzate III α-LA 2 mg / kg body weight of the animal. There is reason to believe that an important role in the mechanism of the protective action of peptides α-LA playing their antioxidant properties. Research has shown that during proteolysis α-LA formed hydrolysates antioxidant activity which correlates with their antiulcer effectiveness.
