- 尼氏小体:尼氏小体是存在于神经元细胞体和树突中的可变大小的离散颗粒状物质,由RNA和多核糖体组成,能被碱性染料(如亚甲基蓝)染色,给细胞带来条纹状的外观。
1 ?尼氏体 1)嗜染质:又称尼氏体(Nissl bodies):光镜下呈小块状或颗粒状,HE染色染成紫 蓝色。电镜下嗜染质由密集平行排列的粗面内质网和游离核糖体构成。 2 ?尼氏小体 1.染色质溶解 染色质溶解(chromatolysis)是指神经细胞胞浆尼氏小体(Nissl bodies)(即粗面内质网)的溶解。 3

The size and Nissl bodies of the anterior horn motor cells were apparently normal, but only 2 cell groups, medial and lateral, could be identified. 前角运动细胞大小及尼氏体正常,分群不如正常胎儿明显,只能分出内、外侧两群。 - 2
Results the Nissl bodies in the spinal cord and the DRG neurons were observed to have pyknosis, accompanied by collapse and karyolysis of Nissl body. 结果D组脊髓和DRG神经元的尼氏体体积减小,并且有尼氏体的脱失和溶解。 - 3
The major lesions included dissolution of Nissl bodies, pyknosis, and incrustation of neuronal surface in the cerebral cortex, thalamus, hippocampus, cerebellum and spinal cord. 主要病变包括大脑皮质、丘脑、海马、小脑和脊髓的神经细胞尼氏体溶解、核浓缩和细胞表面结痂。
