Research Abstract

消化管運動の最終的な組織である平滑筋について、Hirschsprung病(以下H病)無神経節腸管ではこれまで着目されていなかった。そこでH病モデルラットを用いてH病無神経節腸管平滑筋の収縮特性について検討をおこなった。これまでに無神経節腸管平滑筋にはSubstance P(以下SP)刺激による張力は低下しているがSPレセプターは正常に発現しているという報告がある。無神経節腸管平滑筋のSPに対する収縮特性について検討した。前述のように腸管を処理し、細胞内カルシウム濃度-張力の測定をおこなった。定常状態を0%、高濃度カリウム溶液による脱分極による張力、細胞内カルシウムを100%とした。正常腸管:SP投与時張力624.03%、[Ca^<2+>]i78.09%。Rho kinase inhibitor(Y-27632)前投与時張力233.30%、[Ca^<2+>]i45.03%。無神経節腸管:SP投与時張力658.07%、[Ca^<2+>]i 54.16%、Y-27632前投与時張力102.55%、[Ca^<2+>]i69.49%。正常腸管でのSPによる張力は624%と有意に上昇したが、[Ca^<2+>]iの上昇度は変化がなかった。Y-27632投与により、Rho kinaseの関与する経路を遮断したところ、[Ca^<2+>]iの上昇度は変化せず、SPによる張力のみが233%に低下した。これによりH病モデルラットの正常腸管収縮にはRho kinaseが関与していることが判明した。次にHomo typeの無神経節腸管では、SP投与により658%の張力がえられたが、[Ca^<2+>]iの上昇は認めなかった。Y-27632を投与した場合には[Ca^<2+>]iは変化なく、張力は102%に低下した。以上より無神経節腸管平滑筋のSPレセプター以下の収縮メカニズムは正常腸管と同様にRho kinaseを介した経路が存在することが判明した。
