摘要
应用光镜和电镜技术观察了花鲈头肾的显微与超显微结构.结果表明,花鲈头肾是一个重要的造血和免疫器官.头肾实质无肾单位,主要由淋巴组织和血窦构成,可分为淋巴细胞聚集区和粒细胞聚集区.电镜下观察显示,花鲈头肾主要由淋巴细胞、浆细胞、单核细胞、巨噬细胞和粒细胞组成,根据胞浆内特殊颗粒的形态结构和大小将粒细胞分为Ⅰ、Ⅱ、Ⅲ型粒细胞.
Microstructure and ultrastructure of the head kidney of Lateolabrax japonicus were investigated with light microscope and electron microscope. The results, showed that the head kidney of L japonicus was an important organ for hematopoiesis and immunity. Actually, there is no nephron in the parenchyma in which lymphocyte-aggregate and granulocyte-aggregate region were found. It can be distinguished as lymphoid tissue and blood sinuses. Various kinds of immune ceils were found in the head kidney of L japonicus, including lymphocytes, plasma cells, monocytes, maerophages and granulocytes, which can be divided into Ⅰ granulocytes, Ⅱ granulocytes, Ⅲ granulocytes according to the morphology and size of the special granules in cytoplasm.
