摘　　要：为探明三黄鸡小脑皮质各层的细胞构筑和GABA免疫反应神经元在其小脑内的分布情况,采用尼氏染色和免疫组织化学SABC技术,对10羽三黄鸡的小脑进行了研究。研究发现:三黄鸡小脑皮质各层的细胞构筑与北京鸭、乌鸡、鸽子和非洲鸵鸟的大体相似;GABA免疫阳性细胞位于小脑皮质的蒲肯野细胞层中,阳性较明显;小脑中央核也有大量阳性神经元,多数呈梭形或不规则多边形,多数神经元胞质呈强阳性染色。以上结果表明:GABA阳性神经元在三黄鸡小脑皮质各层均有分布,GABA可能在介导小脑复杂功能中发挥重要作用。In order to investigate the cytoarchitecture of cortex and the distribution of GABA-immunopositive cells in the cerebellum of Sanhuang chicken,the cerebellums of ten Sanhuang chicken were studied by Nissl staining and SABC techniques.The results showed that the cytoarchitecture of cerebellar cortex of Sanhuang chicken was similar to that of Pekin duck,silky fowl,pigeon and African Ostrich.GABA-immunopositive cells were located in the Purkinje cell layer of cerebellar cortex,and their immunopositive were especially strong.A large number of GABA-immunopositive cells were also distributed in the cerebellar nuclei,which taking on fusiform or irregular polygon and their cytoplasm were intensively stained.The results of the present study demonstrated that GABA-immunopositive cells were distributed in the cerebellar cortex,which had a vital influence on maintaining cerebellar complicated function.
