摘要
[目的]为今后研究肉鸽免疫功能提供其免疫器官的形态学、组织学观察依据。[方法]选取40日龄的肉鸽,摘除法氏囊、脾脏和胸腺进行形态学观察;通过制作常规石蜡切片,苏木精—伊红染色,显微照相进行组织学观察。[结果]40日龄肉鸽法氏囊黏膜上皮完整,黏膜固有层腔上囊小结数量减少,体积变小,中间出现空泡,淋巴细胞减少;法氏囊小结中皮质和髓质界限不明显,小结周围有大量的结缔组织增生,导致法氏囊免疫功能降低。脾脏各组织结构发育趋于完善,细胞排列紧密。胸腺髓质中淋巴细胞较少,可见胸腺小体;皮质中淋巴细胞较多。[结论]40日龄的肉鸽法氏囊开始萎缩,免疫功能降低,而脾脏和胸腺免疫功能正常。
[ Objective ]To provide morphological and histological foundation for the further study on immune function of immune organs of boiler pigeon. IMethodslThe 40-day-old boiler pigeons were chosen in this study, and the main immune organs, including bursa of Fabricius, spleen and thymus, were collected to prepare paraffin sections by HE staining method and were morphologically observed and mierophotographed. [Results]The structure of nmcosa epithelium of bursa of Fabricius was intact. The number of nodule in lamina propria layer of bursa of Fabricius mucosa was fewer, and the size of the nodule was smaller. In lamina propria layer, the vacuoles were observed and the number of lymphoeytopenia was fewer. The margin between the cortex and medulla of the nodule in bursa of Fabricius was not obvious, and the proliferation of a large number of connective tissue surrounding the nodule was observed, which resuhed in the immune function reduction of bursa of Fabricius. The development of the tissues and structures of spleen were mature, and the cells arranged closely. The number of lymphocytopenia in the medulla of thymus was fewer, and the thymie corpuscle was observed. The number of lymphoeytopenia in the cortex was more. [ Conelusion ] The bursa of Fabricius of 40-day-old boiler pigeon was atrophied, and its immune function was reduced. The immune function of spleen and thymus was normal.
