摘　　要：目的研究大鼠臂丛 5条主支感觉纤维在脊髓胶状质的定位投射。方法按照跨神经节溃变的原理 ,采用酸性磷酸酶法。结果大鼠臂丛 5条主支的感觉纤维在脊髓胶状质的纵向投射 ,主要到脊髓C5上段至T1上段胶状质 ,少数动物还投射至C4 下段及T1中下段。其横向投射主要位于胶状质内侧半及胶状质外侧半内侧 1 / 3区域 ,部分动物C7上段至T1上段的投射占居胶状质外侧半内侧 2 /Objective To study the orientational projection of sensory fibres of brachial plexus’five branches onto the substantia gelatinosa(SG) of the spinal cord in rats.Method The model with transganglionic degeneration was established and then observed by using acid phospatase technique.Results It was found that the afferent fibers of the brachial plexus′five branches were longitudinally projected onto the SG chiefly from the upper segment of C 5 to the upper segment of T 1,and in a few rats,also onto the lower segment of C 4 and the middle and lower segment of T 1,transversally projected mainly onto the medial half of the whole SG and 1/3 of lateral half of the SG against the medial,and in some rats,onto the SG from the upper segment of C 7 to the upper segment of T 1,covering 2/3 of lateral half of the SG against the medial.
