为了解大鼠腓浅神经传入纤维在脊髓胶状质（ＳＧ）的投射定位，按照跨神经节溃变原理，用抗氟化物酸性磷酸酶（ＦＲＡＰ）法和显微测量进行定量研究。结果显示：大鼠腓浅神经向ＳＧ的纵向投射主要为Ｌ２～６，Ｌ２～６各节段ＳＧ水平切面“眉毛状反应带”弧形长均值分别为０．７９５、０．８４９、０．９１３、０．９２１、０．８５２ｍｍ；而腓浅神经向Ｌ２～６各节段ＳＧ水平切面投射均值分别为０．４４７～０．５３３、０．３８４～０．５６１、０．３５１～０．５９８、０．３３８～０．６１１、０．３８３～０．５６１ｍｍ的范围。结果表明，腓浅神经反应带占据ＳＧ中间区域
In order to understand the projection localization of the peroneal nerve afferent fibers in the glia (SG) of the spinal cord, a quantitative study using anti-fluoride acid phosphatase (FRAP) and microscopic measurements was performed according to the principle of trans-ganglion degeneration. The results showed that the longitudinal projection of the superficial peroneal nerve to SG was mainly L2 ~ 6, and the average length of arc-shaped “eyebrows” zone of the SG horizontal section of L2 ~ 6 was 0.795,0.849,0 respectively. 913,0.921,0.852mm; mean projection of superficial peroneal nerve L2 ~ 6 segments of the horizontal section of the average projection of 0.447 ~ 0.533,0.384 ~ 0.561,0.351 ~ 0. 598, 0.338 ~ 0.611, 0.383 ~ 0.561 mm. The results show that the peroneal nerve reflex zone occupies the middle of the SG region
