目的：研究大鼠腓深神经传入纤维在脊髓胶状质（ＳＧ）的投射定位。方法：按照跨神经节溃变的原理，用抗氟化物酸性磷酸酶（ＦＲＡＰ）法和显微测量进行定量分析。结果：大鼠腓深神经向ＳＧ的纵向投射主要为Ｌ２～Ｌ６上部。Ｌ２～Ｌ６各节段ＳＧ水平向眉毛状反应带长所测均值分别为０．７６１、０．８２５、０．８８７、０．８９８、０．８１９ｍｍ，而腓深神经向Ｌ２～Ｌ６上部各节段ＳＧ水平向投射所测均值分别在０．４１４～０．４８１、０．３６２～０．５１４、０．３３５～０．４７２、０．３３９～０．４３７、０．３７２～０．４３９ｍｍ的范围。结论：腓深神经投射区主要位于ＳＧ的中间带偏内。
Objective: To study the projection localization of deep peroneal nerve afferent fibers in the glial lineage (SG) in rats. Methods: According to the principle of trans-ganglion degeneration, quantitative analysis was carried out by means of FRAP method and microscopic measurement. RESULTS: Longitudinal projection of the deep peroneal nerve to SG was mainly in the upper part of L2 ~ L6. L2 ~ L6 each segment of SG horizontal eyebrow reaction length measured mean values were 0.761,0.825,0.887,0.898,0.819mm, while the deep peroneal nerve L2 ~ L6 upper section Segment SG horizontal projection measured mean were 0.414 ~ 0.481,0.362 ~ 0.514,0.335 ~ 0.472,0.339 ~ 0.437,0.372 ~ 0.439mm range. Conclusion: The deep peroneal nerve projection area is mainly located in the middle of SG.
