摘　　要：应用雄性家兔12只,将20%HRP溶液100μl沿左肾门注入肾的纤维膜下.结果:在所有家兔的双侧脊神经节内均发现有标记细胞,计有1316个,其中同侧有1075个,占81.68±1.06%;对侧有241个,占18.31±1.06%.肾经交感神经传入的节段分布于:同侧T_(10)-L_4节段,但T_(12)-L_2节段较集中,有842个,占78.32±1.25%,对侧分布于T_(11)-L_2节段,而T_(12)-L_2较集中,有194个,占80.49±2.55%.标记细胞的大小甚为悬殊,细胞中以中小型细胞为主,占81.15±1.07%.The segmental distribution of kidney afferent neurons was investigated by using the method of HRP retrograde transport in 12 rabbits 1316 labeled cells were found in the bilateral spinal ganglia,with 1075 cells (about 81.68±1.06%) on the ipsilateral and 241 cells (about 18.31±1.06%) on the contralateral.The labeled afferent neurons were found to be distributed in ipsilateral dorsal root ganglia T_(10)-L_4,concentrating mostly between T_(12)-L_2 and in the contralateral dorsal root ganglia T_(11)-L_2,concentrating mostly between T_(12)-L_2,The labeled cells varied greatly in size.Their diameters ranged from 15μm to 120μm,most of them between 15～49μm The results suggested some new ideas about the kidney afferent neurons.
