摘要
通过光镜和电镜观察发现，草鱼（Ｃｔｅｎｏｐｈａｒｙｎｇｏｄｏｎｉｄｅｌｕｓ）头肾器官有两种静脉（头肾静脉和门静脉）和丰富的血窦。淋巴细胞主要分布在门静脉及其血窦周围，形成淋巴细胞聚集区。粒细胞主要分布在头肾静脉及其血窦周围，形成粒细胞聚集区。头肾含有大量的免疫细胞，其中淋巴细胞约占６２２％，粒细胞约占３６６％，单核细胞和巨噬细胞约占１２％。本研究检测了不同生长发育期的草鱼头肾器官重量及其免疫细胞数量。结果说明草鱼头肾器官重量随体重和鱼龄（特别是体重）的增加而增加，头肾免疫细胞总数则随头肾重量增加而相应增加，但是每毫克头肾组织的免疫细胞数则通常是稳定在１００—１３２万个之间，均值１１７３（±９９８）万个。
Under light and electron microscope,the head kidney of grass carp was found to have two type of veins:head-renal and portal veins,and a number of sinusoids with extensive lumina The lymphocytes of head kidney were distributed around portal veins and its sinusoids,forming lymphocyte aggregate region,while granulocytes distributed around head-renal veins and its sinusoids,forming granulocyte aggregate region The head kidney contained a number of immune cells,comprised approximately 62 2% lymphocyte,36 6% granulocytes,1 2% monocytes and macrophages The weight of head kidney organ and amounts of its immune cells were examined for each grow stage of grass carp It was shown that total weight of head kidney increased with body weight and age However,The development of the head kidney correlates better with weight than with age Total number of immune cells of head kidney increased correspondingly with head kidney weight In general,the number/mg weight of head kidney stabilized from 100 to 132 ten thousand,the mean was 117 3(±9 98)ten thousand
