用Nissl氏和weil氏染色法比较研究了41例大白鼠、猫和人缰核的细胞构筑。根据细胞的形态与分布,缰核均可分为内侧与外侧两个部分。内侧缰核均不能分出亚核;而外侧缰核的腹外侧区却存在着一个中、大细胞相对集中区,为外侧缰核腹外侧亚核。定量研究结果显示,大白鼠缰核的神经细胞密度最高,其次是猫,人缰核的细胞密度最低,而三者的内侧缰核细胞密度均高于外侧缰核,经统计学处理均有极显著意义。胶质细胞指数正相反,人缰核的胶质细胞指数最高,猫其次,大白鼠最低。上述结果提示,人缰核的功能比猫和大白鼠的可能更活跃、更发展。
The cell construction of 41 rats, cats and human habenucleus was compared with Nissl’s and Weil’s staining. According to the morphology and distribution of cells, habenula can be divided into two parts inside and outside. Medial habenula can not be separated sub-nuclear; while the lateral ventricular haunch nucleus in the vena cava but there is a relative concentration of large cells, the lateral vena cynocephala lateral ventricle. The results of quantitative study showed that the density of neurons in the habenula of rats was the highest, followed by that of cats. The density of the human habenucleus was the lowest, while the density of the medial habenula was higher than that of the lateral habenula, and statistically significant Significant. Glial cell index is the opposite, human habenular glia cell index highest cat second, the lowest in rats. The above results suggest that human habenular nucleus function may be more active and more developed than cats and rats.
