chronic constriction of the sciatic nerve and pain hypersensitivity testing in rats

慢性の神経因性疼痛は、中枢または末梢神経系への損傷に起因する、人口の1,2の7から18パーセントに影響を与え、流行と衰弱状態です。症状は、自発的（のようなうずき、燃焼、電気ショック）の痛み、dysaesthesia、感覚異常、アロディニア（痛みは通常は非痛み刺激に起因する）と痛覚過敏を（痛み刺激に対する応答の増加）が含まれています。感覚症状は、不眠やうつ病などの行動障害との併存である。慢性神経因性疼痛を勉強する末梢神経損傷を模倣するいくつかの動物モデルが開発されている、最も広く使用されているの一つは、ベネットと謝（1988年）一方的な坐骨神経の慢性狭窄損傷（CCI）3（ 図1）。ここでは、CCIとテストの疼痛過敏を実行するための手法を提案する。 CCIは、次のようにすることによって公開された一方の側の坐骨神経で、全身麻酔下で行われる親族切開し、中殿浅と大腿二頭筋の筋肉の間に結合組織を切断する。四クロム腸の字だけ閉塞するために、1ミリメートルの間隔で坐骨神経の周りにゆるく結んが神経鞘の血流を逮捕されていません。傷は皮膚の筋肉やステープルで縫合閉鎖しています。疼痛過敏症テストを開始する前に、動物は、その後24時間の手術から回復するために許可されています。 行動テストのために、ラットを試験装置に配置され、テスト手順に慣らすために許可されています。テストエリアは、坐骨神経の分布範囲内に後足の半ばに底表面（ 図2）です。機械的な撤退のしきい値は機械的に電子の動的足底のフォン·フレイ角膜知覚計またはマニュアル·フォン·フレイ毛4を使用して負傷し、無傷の後肢の両方を刺激することによって評価されています。機械的な撤退のしきい値は、作用する最大圧力です。（グラム）足の撤退をトリガします。第一ハーグリーブスら （1988）によって記述され、熱回収の遅延の測定については、後足は足鎮痛メーター5,6を使用して、透明なガラス表面からの放射熱のビームにさらされている。熱刺激に撤退レイテンシが負傷し、無傷の両方の後肢の足撤退のための時間として記録されます。以下CCI、負傷した足に機械的な撤退のしきい値と同様に、熱回収の遅延は、ベースラインの測定と無傷の足（ 図3）と比較して、両方とも大幅に減少しています。疼痛過敏症テストを組み合わせた末梢神経損傷のCCIモデルでは、慢性の神経因性疼痛を変更するには、潜在的な治療薬の有効性を検討するためのモデルシステムを提供します。私たちの研究室では、病因に神経免疫相互作用の役割を調べるために後肢の熱的、機械的な感度と一緒にCCIを活用神経因性疼痛の治療と。
