The study was performed to clarify a protectiveeffect of barley and oats on gastric stress ulcerogenesis. Draftclassified barley flour(75% yields) without any treatment ofheating and addition of humidity, and Canadian oats flour(57%yields) as the materials of soluble dietary fiber,β-(1→4),(1→3)-glucan were used.Gastric stress ulcerogenesis induced by water immersion wereconducted using SDjcl rats 5 weeks old(7 rats in one group).
The results were as follows :
1. The contents of soluble dietary fiber andβ-(1→3)-glucan contents in barley flour and oatsflour were 4.60% and 5.54%, and 3.40% and 4.75%, respectively.
2. The strong anti-ulcerogenesis was observed in rats fed on allthe diets containing 10% and 5% of barley and/or oats.
3. The protective effect of barley flour was equivalent to that ofoats flour in spite of the different β-(1→3)-glucan contents.
4. The protective effects of 5% barley and oats diets reduced byabout 50% the protective effects of 10% diets, respectively.
Key Words: gastric stress ulcer,β- (1→3)-glucan,soluble dietary fiber, barley, oats. |
