| Outline of Final Research Achievements |
The bacterial solutions (Pg, Fn, or PgFn) or PBS (Control) were injected into the tail vein of pregnant mice once a day from 8 days at gestation to 10 days at gestation or from 13 days at gestation to 15s day at gestation.
Our results showed that (i) Pg and Fn injected into the tail vein of pregnant mice stayed in placentas, that (ii) the Pg and Fn in placentas involved with growth and development of fetus, and that (iii) the effects of injection of periodontal pathogens from 13 days at gestation to 15 days at gestation were worse than those from 8 days at gestation to 10 days at gestation. In addition, we suggested that (i) the gene expressions of inflammatory mediators in placentas of mice to which periodontal pathogens were injected were tend to higher than those in placentas of control mice and (ii) the gene expressions of inflammatory mediators in placentas of mice to which Fn were injected were most increased in placentas of mice to which periodontal pathogens were injected.
