本文主要研究神经细胞分裂像的特征,分裂像出现的部位,数量,形态特点及神经细胞分裂和非神经细胞分裂的鉴别以及神经细胞在分裂末期胞体是如何分离的。切除成年大白鼠双侧顶叶正中部4×3×1mm~3的大脑皮质,术后第四天取大脑组织固定,切片,用苏木素-伊红和尼氏染色。观察结果为: 1.实验动物中有38％大脑皮层中出现35个明显的神经元分裂像。以第Ⅴ层最多。神经元分裂大多见于创伤区附近正常组织内,其距离为37～1,239.5μm范围内。 2.大脑皮质的锥体细胞进入有丝分裂期仍呈锥体形,细胞有明显的极性。 3.根据神经元特有的形态——锥体型、细胞的极性(有顶树突)和胞质内的特有物质(尼氏体)的有无作鉴别。
In this paper, we mainly study the characteristics of neuronal cell division, the location, quantity, morphological characteristics of the split images, the identification of neural cell division and non-neuronal cell division, and how the neural cells separate at the end of division. The cerebral cortex of 4 × 3 × 1mm ~ 3 in the middle of bilateral parietal lobe of adult rats was excised. The brain tissue was fixed and sectioned on the fourth day after operation, and stained with hematoxylin-eosin and Nissl. The observation results were as follows: 1. There were 35 obvious neuronal schizophrenia in 38% of the cerebral cortex in experimental animals. The fifth floor up to. Most neurons were found in the normal tissue near the wound area, the distance between 37 ~ 1,239.5μm range. 2. Pyramidal cells of the cerebral cortex into the mitosis into pyramidal shape, the cells have obvious polarity. 3. According to neuron-specific morphology - pyramidal, cell polarity (apical dendrites) and the cytoplasm of the unique material (Nissl) whether or not to identify.
