摘要
本实验用HRP逆行追踪法对大鼠肾上腺交感神经节前神经元进行了定位研究,并对中间外侧核4个亚核的性质及其与脑干、下丘脑的联系进行了讨论。其结果如下:实验组11只大鼠都有标记细胞,对照组2只大鼠均无标记细胞。标记细胞位于注射侧T_1—L_1脊髓节段,主要位于中胸段,以T_(10)节段最多。标记细胞主要集中于中间外侧核本部,占细胞总数的85.12％。细胞体以梭形为主,成群或单个排列。延髓无标记细胞。
The authors determined the situation of the sympathetic preganglionic neurons of rat adrenal gland in spinal cord with retrograde tracing HRP method, discussing the nature of 4 subnuclei of intermediolateral nucleus and the relationship between those neurons and brain stem or hypothalamus. The results were as follows: Labelled cells were observed in the spinal cords of all 11 rats in experimental group,but no labelled cells were found in 2 rats in control group. The labelled cells were observed in the spinal cord from T_1to L_1 segments,ipsilateral to the side of the injecton. The labelled neurons were mainly located in the tenth thoracic segment. The cells primarily presented in nucleus intermediolateralis thoracolumbalis pars principlis (85.12％ of the total labelled cells). Cell bodies were mostly spindleshaped, distributed in group or singleness. No labelled cells were found in the medulla oblongata.
