尼氏体

1
组髓鞘及尼氏体病变明显减轻。
The neuropathies in myelin sheath and Nissl body were markedly attenuated in group K.
2
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。
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.
3
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。
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.

尼氏体
神经元胞体或树突内大的嗜碱性团块和颗粒，又名“嗜染质”。旧称嗜色体。轴突及其起始胞体部则无。为尼氏(Nissl，1892)首先发现，故得名。在一些大型运动神经元，尼氏体大而多，色染深蓝或紫色，常给神经元胞体以虎斑外观，又称虎斑小体。亦可依该体的大小、染色深浅等，对神经元进行分类。
