Outline of Final Research Achievements

We investigated the relation between gut microbiota and gastric acid secretion, and the effect of Japanese apricot (JA) on the microbiota. Healthy Japanese subjects with H.pylori-/atrophic gastritis- (Group A) and H.pylori-/atrophic gastritis+ in which gastric acid secretion has markedly reduced (Group D) were enrolled. This trial composed of 4 parts (Part 1: Group A vs Group D before JA, Part 2: all cases before vs after JA, Part 3: before vs after JA in Group A, Part 4: before vs after JA in Group D). Significant differences were observed in not the diversity but the structure of the gut microbiota in some parts of the trial. In Part 1, c_Clostridia at the class level and o_Clostridiales at the order level were significantly different. In Part 4, Bacteroidetes at phylum level was significantly different. These results show that gastric acid might be related to the structure of the gut microbiota, and JA might alter the structure in the reduced gastric acid condition.

Academic Significance and Societal Importance of the Research Achievements

梅エキス投与による腸内細菌叢改善が証明されれば、病変の発生を予防する広大なる戦略構築に貢献する一助となることが予測され、健康増進に大きな福音となることが考えられる。
