Research Abstract

歯周病の病原菌であるグラム陰性菌は、全てその外膜成分として内毒素を保有している。今回実験に供した内毒素は、歯周病原性グラム陰性菌から抽出した。Porphyromonas gingivalis ATCC33277、FDC381、実験動物に強い病原性を示す16-IFI株およびその継〓を繰り返した16-IRT株を用いた。Provotella intermediaは、ATCC25611、ATCC33563株を使用した。Actinobacillss actinomy et-emcomtansはY4株、Fusobacterium nucleatumはATCC25586株、Eikeuella corrodensはFDC1073株を供討した。内毒素であるlipopolysaccharideは、water-phenol法によって抽出した。実験的ペリクルは、ヒドロキシマパタイトビーズを血清あるいは唾液でcoatした。LPSの量は、リムルステストを指標として測定した。抽出LPS標品をSDS-PAGE後、silver染色したところ、P.gingivalisの全ての株、F.nucleatum株のLPSは繰り返しの0-拾原多糖体をもつことから、smooth型のwildタイプに属することがわかった。一方P.intermedia、A.actinomycetemcomitans およびE.corrodensのLPSは0-拾原多糖体側鎖を持たないことからrough型のLPSに属することがわかった。今まで報告してきたようにrough型のLPSは、供請した動物およびヒトの赤血球を凝集したことを確認できた。また唾液や血清をcoatした実験的ペリクルへの付着は、赤血球凝集能のあるrough型LPSに顕着であった。P.gingivalisのLPSの実験的ペリクルおよびヒドロキシマパタイトへの付着は、ほとんど認められなかった。in vitroの今回の実験結果は、歯周病原性グラム陰性球菌がin vivoでどのような役割りを果たしているかを考えると(1)、菌の歯周局所への定着因子、(2)歯周組織体にセナント質へ吸着して組織障害を起こしていることが考えられる。
