| Outline of Final Research Achievements |
We examined the effects of Lactobacillus paracasei during pregnancy and lactation on in mice fed a high-fat diet. Lb. paracasei reduces the content of liver lipids in pups of high-fat diets. It is thought that ingesting Lb. paracasei affects the formation of bacterial flora in dams.
The probiotic of Lb. paracasei was examined. Lactobacillus casei was used as a control. Lb. paracasei showed high tolerance for the gastric juice although the tolerance for bile acid was low. Cholesterol and bile acid binding abilities of Lb. paracasei was higher than L. casei. Therefore, it was suggested that Lb. paracasei may be effectively applied as probiotics Lactobaillus.

| Academic Significance and Societal Importance of the Research Achievements |
Lactobacillus paracasei NFRI 7415は、生きたまま腸に到達し、腸内細菌叢の改善に役立つと同時に、乳酸菌のコレステロール低下作用が脂質代謝や腸管免疫に影響を与えていることが示唆された。本研究の成果は、妊娠・授乳期の母親と乳児の生活習慣病予防と健康増進に寄与する新規なプロバイオティクス効果を有する食品素材となり得ると考える。
