本文用光镜(Wright氏染色和组化反应)和透射电镜观察鳙鱼外周血细胞.在Wright’s染色的血涂片上,可以区分:红细胞、淋巴细胞、血栓细胞、单核细胞和颗粒细胞.淋巴细胞是数目最多的白细胞,而单核细胞的数目较少.电镜观察下,红细胞的细胞器较少,只有一些囊泡样体和少量线粒体.血栓细胞由于有大量的液泡和边周微管而与小淋巴细胞有较大区别.虽然单核细胞在体积和形态上酷似颗粒细胞,但单核细胞有更丰富的粗面内质网和游离核糖体,而颗粒细胞含更多的特殊颗粒.颗粒细胞有两种类型:Ⅰ型颗粒细胞和Ⅱ型颗粒细胞.这两种颗粒细胞都是嗜中性粒细胞,是同一种细胞的不同发育时期.本文还描述了这两种颗粒细胞的重要特征.
In this paper, we observed the peripheral blood cells of catfish by light microscopy (Wright’s staining and histochemical reaction) and transmission electron microscopy. On Wright’s stained blood smears, they were divided into erythrocytes, lymphocytes, thrombus cells, monocytes and granulocytes. Cells are the largest number of white blood cells, while the number of mononuclear cells.Electron microscopy, erythrocytes organelles less, only some of the vesicle-like bodies and a small amount of mitochondria .Thrombocytes due to a large number of vacuoles and peripheral microtubules and Small lymphocytes are quite different. Although mononuclear cells resemble granulosa cells in size and morphology, monocytes have richer endoplasmic reticulum and free ribosomes, while granulocytes contain more specific granules. There are two types of cells: type I granulosa cells and type II granulosa cells, both of which are neutrophils that are at different developmental stages of the same cell.The important features of both granulosa cells are also described herein .
