With CB-HRP method (injections into 5 muscles of anterior and posterior extremities) and Golgi technique, the corresponding sections of spinal cords were observed on same aged rats of the identical parent rats. Comparing the cell numbers of the lateral groups of anterior horns, the former (CB-HRP) revealed twice as many as the cell numbers of the latter (Golgi). As to the surface densities of the white matter dendrites (WMD) in the lateral funiculi from the neurons of the lateral groups of the anterior horns, the density revealed by injection of CB-HRP to the tibialis anterior is 2-9 times more than that in Golgi sections. All of WMD revealed in CB-HRP sections could extend into the peripheral portions of the lateral funiculi, and quite a few of them even form a subpial marginal plexus, that is one example of Golgiphobic dendrites (GBD). For labeled medial cell groups of the anterior horn with CB-HRP, their dendrites could reach to the ependymal layer of the central canal (another GBD). These two types of GBD were not present on the Golgi material. The significance of GBD was also discussed.
采用CB-HRP法（注入前后肢的5块肌肉）和高尔基技术，在同一亲代大鼠的同龄大鼠上观察脊髓的相应切片。比较前角外侧群的细胞数量，前者（CB-HRP法）显示的细胞数量是后者（高尔基技术）的两倍。至于前角外侧群神经元在外侧索中的白质树突表面密度（WMD），向胫骨前肌注射CB-HRP所显示的密度比高尔基切片中的密度高2至9倍。CB-HRP切片中显示的所有WMD都可延伸至外侧索的周边部分，其中相当一部分甚至形成软膜下边缘丛，这是疏高尔基树突（GBD）的一个例子。对于用CB-HRP标记的前角内侧细胞群，它们的树突可到达中央管的室管膜层（另一种GBD）。这两种类型的GBD在高尔基材料上未出现。还讨论了GBD的意义。
