摘要: 研究了番鸭法氏囊柄部淋巴组织的分布及组织学结构。番鸭法氏囊柄部分布有多量的淋巴组织,以法氏囊柄的背侧淋巴组织分布面积最大、数量最多。其组织学结构包括淋巴相关上皮、上皮内淋巴细胞、圆顶区、淋巴滤泡以及高内皮静脉,其结构与其他粘膜相关淋巴组织相似。研究结果表明,分布于法氏囊柄部的淋巴组织是一种粘膜相关淋巴组织。Abstract: The distribution and histology of lymphoid tissue in the Fabricius’bursal stalk were studied.There were large amount of lymphoid tissue in Fabricius’bursal stalk.The largest distribution area and the great quantity were at the dorsum of the stalk.The bursa-associated lymphoid tissues included follicle associated epithelia (FAE), intro-epithelial lymphocyte (IEL), dome area, lymphoid follicles and highendothelial venules.Their structures were similar to other mucosa-associated lymphoid tissues (MALT).The results indicated that the lymphoid tissue of Fabricius’bursal stalk was one kind of the MALT.
