以下の実施例において、本発明を例証するが、本発明はこれら実施例の記載に限定されるわけではない。
全12匹(1ヶ月モデル、2ヶ月モデル、3ヶ月モデル各4匹ずつ)のビーグル犬(雄、10〜12ヶ月齢)を使用した。歯周病の発症機序としては、歯周ポケットに食べ物や歯垢が堆積することによって感染を起こし歯周病へと発展する。その際、炎症によって歯槽骨の吸収(退縮)が起こる。したがって、本モデルのように糸を巻くことで、歯周ポケットに食べ物や歯垢が堆積しやすくなり、歯周病が引き起こされる。図1にその模式図を示す。図1において、左図は糸を結紮したモデル作製時の模式図であり、時間がたつと右図のように歯槽骨の吸収(退縮)が起こる。
IL−6は、常法にしたがってELISAで測定した。その結果を表1および図11に示す。
なお本明細書において引用された全ての先行技術文献は、参照として本明細書に組み入れられる。
本実施例に用いたビーグル犬(雄、10〜12ヶ月齢)骨欠損モデルは、静脈麻酔下、左右それぞれに、近心小臼歯部より歯肉弁を作製して歯槽骨を露出させ、大臼歯歯根分岐部に歯科用バーにて直径5mmの3壁性骨欠損を作製したものである。 左臼歯の骨欠損部位にはコラーゲン基材(AteloGeneTM)に混入したNFκB デコイを、右臼歯の骨欠損部位には同様に混入したスクランブルデコイを、それぞれ埋没投与した。使用したデコイは、上記実施例と同様1 mg/100μlになるように調製して用いた。デコイの埋没投与後、歯肉弁を復位して縫合した。手術後2週間で歯肉弁は治癒し、外部からの感染刺激等は遮断された。また、手術直後から術後4週間までの間、2週間間隔でレントゲン撮影することにより、骨欠損修復過程を観察した(図12)。
