大鼠腋神经一级传入纤维在脊髓胶状质定位投射的定量分析——FRAP法

THE QUANTITATIVE ANALYSIS OF THE ORIENTATIONAL PROJECTIONS OF THE PRIMARY AFFERENT FIBERS OF THE AXILLARY NERVE TO THE SG OF SPINAL CORD IN RATS __FRAP METHOD

用抗氟化物酸性磷酸酶（ＦＲＡＰ）法和显微测量，对大鼠腋神经一级传入纤维在脊髓胶状质（ＳＧ）的定位投射进行了定量分析。大鼠腋神经向ＳＧ的纵向投射主要在Ｃ５～Ｃ７，Ｃ５～Ｃ７各节段ＳＧ水平向“眉毛状反应带”宽所测均值（ｍｍ）分别为０．８７２、０．９２０、０．９６０，而腋神经向Ｃ５～Ｃ７各节段水平向投射所测均值（ｍｍ）分别在０．３９０～０．５０８、０．４３２～０．６０５、０．４９７～０．

The quantitative analysis of the orientational projections of primary afferent fibers of the axillary nerve to the substantia gelatinosa (SG) of spinal cord in rats were made by adopting fluorideresistant acid phosphatase (FRAP) method and micromeasurement technique. The longitudinal projection of the axillary nerve to SG was found in C5～C7. The mean value of horizontal “eyebrowlike” reactive zone of the SG in C5～C7 was measured as 0872mm, 0920mm and 0960mm, respectively. And the mean value measured in the horizontal projection of axillary nerve to C5～C7 was respectively 0390～0508mm, 0432～0605mm and 0497～0658mm. (WT5HZ〗
