        Antiulcerative Activity of Milk Proteins Hydrolysates

        Several studies have shown the protective effect of dairy products, especially α-lactalbumin and derived hydrolysates, against induced gastric ulcerative lesions. The mucus strengthening represents an important mechanism in the defense of gastrointestinal mucosa. Previously, a hydrolysate from casein (CNH) and a hydrolysate from whey protein concentrate rich in β-lactoglobulin (WPH) demonstrated a stimulatory activity on mucus production in intestinal goblet cells. The aim of this work was to evaluate the possible antiulcerative activity of these two hydrolysates in an ethanol-induced ulcer model in rats. All tested samples significantly reduced the ulcerative lesions index (ULI), compared with the saline solution, using doses of 300 and 1000 mg kg−1 body weight with decreases up to 66.3% ULI. A dose–response relationship was found for both hydrolysates. The involvement of endogenous sulfhydryl (SH) groups and prostaglandins (PGs) in the antiulcerative activity was evaluated using their blockage. The antiulcerative activity of WPH showed a drastic decrease in presence of N-ethylmaleimide (from 41.4% to 9.2% ULI). However, the CNH antiulcerative properties were not significantly affected. The cytoprotective effect of WPH appears to depend on a PG-mediated mechanism. In conclusion, CNH and WPH demonstrated in vivo antiulcerative properties and represent a promising alternative as protectors of the gastric mucosa.
