摘要
本实验用HRP法对家兔子宫初级感觉神经元在脊神经节的节段性分布规律进行了研究。酶标细胞出现在T_(9)~Co_(1)脊神经节范围内。较集中于L_(2~5)和S_(3、4)脊神经节,尤以L_(4)和S_(3)节最多。而L_(6、7),S_(1)节很少。胸腰段与骶尾段酶标细胞数的比约为5:1。兔子宫以源自颈部标记神经元数量较多。源自子宫体中部的标记神经元分布较少,上、卜两部标记的神经的数量相近。子宫各部感觉的传入节段一致。子宫的初级感觉神经元,以小细胞为主,中细胞次之,大细胞最少。初级感觉,均传入同侧脊神经节中,左右未见交叉现象。
The distribution of the primary sonsory neurons from the uterus was studied in 20 female rabbits by the HRP method.The results were as follows:The HRP-labeled cells were found in all the spinal ganglia from T_(9)to Co_(1),but they were highly concentrated in two groups,namely L_(2~5)and S_(3~4).There were more labeled cells in the lumbar group than in the sacral group with the highest freguency in L_(4)and S_(3)ganglion in each group respectively.There were only a few labeled cells in L_(6~7)and S_(1)spinal ganglia.The ratio of labeled cells in the thoracic and lumbar ganglia to those in the sacral and coccygeal was about 5:1.The number of labeled cells was largest following injection of HRP in the uterine cervix,smallest in the middle of the body and intermidiate in the upper and lower rogions of the uterine body.There is no difference in the distribution of labeled cell from different regions of the uterus.The majority of labeled cells were small,only a few were large ones.
