Outline of Final Research Achievements

In order to elucidate the mechanism of preventive actions by plant-derived polyphenols for periodontal diseases, we examined the ameliorating effect of Jixueteng and French pine bark extract on gingival microcirculation disorder caused by P. g infection. Administration of Jixueteng to P. g-infected mice improved the gingival capillary network disorders to non-infected control levels. In addition, administration of Jixueteng or pine bark extract showed significant improvement in hyperemia of the palate gingiva caused by ischemia.
Furthermore, the inhibitory effects of the pine bark extract on the biofilm formation by P. g, A. a and S. m were evaluated. The number of viable bacteria was dose-dependently decreased and the accumulation of bacterial cells was inhibited. The results suggest that plant-derived polyphenols may useful to prevent periodontal diseases by suppressing plaque formation and improving gingival blood circulation.

Academic Significance and Societal Importance of the Research Achievements

歯周炎は細菌感染に起因する炎症性疾患であり、歯周組織の破壊は局所で産生される活性酸素種(ROS)の関与が指摘されている。様々な生理活性が認められる植物ポリフェノールは、抗酸化作用を有するとともに実験的歯周炎での歯槽骨吸収を抑制することが報告されている。その抑制機序の一環として、鶏血藤や松樹皮抽出物が歯垢形成抑制作用を有し、P. gingivalis により惹起される実験的歯周炎における歯周組織の毛細血管障害を改善することが本研究で明らかとなった。このことは、日常的に摂取する安全性の高い食品類を用いて歯周炎予防が可能であることが示されたことになる。
