体感诱发电位检查腰骶神经根病变的意义

本文采用自制的针电极和改进的方法,记录了50例正常人在分别刺激胫后神经和节段性(根性)皮神经(腓肠和腓浅)时的腰髓电位(LP)和皮层电位(CP);接着又记录和观察了48例单侧L_5或S_1神经根受压患者上述神经受刺激时的LP和CP。结果发现:节段性皮神经刺激的LP异常率达85%,其CP为48%;胫后神经刺激的LP异常率为33%,其CP仅为8%。     

体感诱发电位检查脊髓型颈椎病的意义

应用正中神经和胫后神经ＳＥＰ分别对３１例脊髓型颈椎病患者进行了检测和分析。结果发现：正中神经ＳＥＰ异常２３例（７４％），主要表现为Ｎ１３波幅降低或消失，常伴有Ｎ９～Ｎ１３延长，胫后神经ＳＥＰ异常２７例（８７％），其中有４例所测得正中神经ＳＥＰ正常，主要表现为ＬＰ～Ｐ４０延长或Ｐ４０消失。正中神经和胫后神经ＳＥＰ对评价颈髓功能均有一定价值，二者结合观察意义更大。     

实验性骶_1神经根损伤对家猫体感诱发电位的影响

作者观察了12只猫在不同程度骶神经根受损后刺激胫后神经和腓肠神经诱发的腰髓电位(LP)和皮层电位(CP)的改变。结果发现:S_1神经根受损时,刺激腓肠神经诱发的LP改变最明显,其CP次之;刺激胫后神经诱发的LP改变较小,其CP无显著变化。SEP的改变特征主要表现为波幅下降,而潜伏期无明显变化。

亚硒酸钠对离体蟾蜍脊髓背根电位的影响

本文观察亚硒竣钠对离体蟾蜍脊髓背根电位的作用。结果表明:亚硒酸钠对背根电位(DR-DRP、VR-DRP)的幅度呈现先增高后降低的双相效应。用蔗糖间隙法记录证明亚硒酸钠对背根有去极化作用。通过进一步的实验分析认为:亚硒酸钠所诱发的自发性背根电位是其对中间神经元活动影响的结果。并结合有关资料对亚硒酸钠的作用机制作了初步探讨。     

大鼠后肢皮、肌神经及穴位区诱发脊髓背根电位的传入纤维类别分析

采用分级刺激、直流电阻滞、Novocain阻滞等方法系统分析了大鼠后肢腓肠(皮)神经、腓肠肌神经及拟承山穴区ⅠⅡⅢ类传入纤维诱发的脊髓背根电位(DRP)。结果表明:上述皮、肌神经及穴位区ⅠⅡⅢ类纤维均可诱发负DRP;皮神经DRP主要系Ⅱ类纤维所诱发;肌神经及穴位区DRP主要系Ⅲ类纤维所诱发。本工作为突触前抑制理论与针刺镇痛原理的研究提供了新资料。     

新生期注射辣椒素对成年大鼠脊髓背根及背表面电位的影响

新生期给大鼠注射辣椒素(50mg/kg),于成年时,电刺激腓肠神经诱发的A-DRP和CDP-p_1波,其幅度、时程、潜伏期以及波面积积分值等参数,与对照组相比,均无显著差异。而C-DRP和CDP-p_2波大都缺如。这与外周神经复合动作电位的变化一致。结果提示:Ⅳ类传入纤维机能的长期丧失,对粗纤维传入诱发脊髓的初级传入末梢上PAD似无明显影响, 而对细纤维传入效应有取消作用。
