摘要
通过光镜技术对野生鲻(Mugil cephalus)的脾脏和头肾进行研究发现:脾脏外有薄层结缔组织纤维被膜覆盖,被膜向内延伸将脾脏分成不规则小叶,无明显小梁,含大量淋巴细胞、血细胞、粒细胞,黑色素巨噬细胞中心较多,脾脏中可见较多并行排列的动脉、静脉和神经束,有椭圆体;头肾与肾脏分离,分左右2叶。头肾为网状淋巴样组织,外被膜极薄,无明显的小梁,无肾单位,分为红血细胞聚集区和白细胞聚集区,有黑色素巨噬细胞中心,相对于脾脏,头肾中的动脉和静脉的数量较少。研究结果表明:头肾和脾脏组织是鲻的重要造血器官和免疫器官。
The morphology and histology of spleen and head-kidney in Mugil cephalus were studied by hght microscope. It was found that the surface of the spleen was covered with a thin layer of fibroid connective tissue capsule which extended inwards, dividing the spleen into irregular lobules. The spleen, without obvious trabcula, was chiefly composed of large quantities of lymphocytes, granulocytes, blood ceils and melano- macrophage centers. Many arteries, veins and nerve bundles in parallel arrangement and ellipsoids were found in spleen. The head-kidney had two lobules, separated from the kidney. The head-kidney as a reticular lymphoid tissue, with no nephron and obvious trabcula, was covered with a very thin layer of fibroid cormective tissue capsule as well. There were red blood cell centers, leukocyte centers, melano-macrophage centers in head-kidney. There were fewer arteries and veins in head-kidney compared to spleen. The results showed that the spleen and head-kidney tissue were the major hematopoietic organ and immune organ in the species.
