The experiments were performed on Wistar rats anaesthetized with urethane (1g/kg). The vibration (120-150Hz, 1mm) was applied to the mandible and the reflex activity was recorded bilaterally from the masseter, temporal and digastric muscles. Experiment I: To establish an experiment model, effective parameters such as vibration frequency, direction of vibration, and jaw position (muscle length) to elicit TVRs were determined. Experiment II: Using the established experimental model, We examined effects of hypertonic saline (5%) and mustard oil (20% in mineral oil) injection into the temporal muscle on TVRs. A vibration frequency of 150Hz in horizontal direction and jaw opening position of 7mm apart at the opposing incisor were determined to be the most effective parameters for TVRs. Both chemicals injected into the temporal muscle reduced the TVR amplitude, and the effect of mustard oil was more than that of hypertonic saline. However, the modulatory effect varied among the muscles tested. In conclusion, effective parameters to elicit TVRs were determined and the change in sensitivity of muscle spindles was suspected to be a factor that affect the response of TVRs to noxious stimuli applied to the jaw closing muscles.", "subitem_description_type": "Abstract"}, {"subitem_description": "ラット閉口筋に微小振動刺激を与え誘発される緊張性振動反射(TVR)を指標に閉口筋の興奮性を評価する実験モデルの確立と、この実験モデルを用いて痛み刺激が筋紡錘の活動性にどのような影響を及ぼしているかについて筋電図学的に研究した。実験にはWistar系ラットを用いた｡麻酔はウレタン(1g/kg)を静脈内投与して行った｡高頻度微小振動(120-150Hz、1mm)を発生する振動モータを用い、下顎骨を振動させることで閉口筋に誘発されるTVR応答を両側咬筋、側頭筋ならびに顎二腹筋筋電図にて記録した｡実験Ⅰ)TVR誘発実験モデルを確立するために、振動の頻度、振動方向、開口量について至適TVR誘発条件を調べた｡実験Ⅱ)前項Ⅰで得られた実験モデルを用いて、高張食塩水(5%)あるいはマスタードオイル(20% in mineral oil)を片側側頭筋に注入しTVRに与える影響について検討した｡至適TVR誘発条件を、振動頻度は150Hz、振動方向は水平方向、開口量は7mmと決定した｡5%食塩水あるいはマスタードオイルの注入によって閉口筋に誘発されるTVR応答は変調された｡両刺激溶液ともTVR応答は注入前より減弱され、その減弱はマスタードオイルでより強く得られたが、その変調様式には記録した筋の種類によって相違が認められた｡以上の結果から、至適TVR誘発条件が設定され、痛み刺激が筋紡錘の活動性を変化させる可能性が示唆された｡",
