| 摘 要： | 采用电子显微镜技术研究了不同渗透压条件下美国红鱼外周血细胞超微结构的变化。在海水中，红细胞为长椭圆形，核较小，无细胞器；淋巴细胞呈不规则圆形，核大，有伪足；单核细胞胞胞质中有少量的线粒体，核大且不规则；血栓细胞多呈泪滴状或纺锤状；粒细胞分为Ⅰ型和Ⅱ型粒细胞，Ⅰ型粒细胞中具有较多高电子密度的颗粒，Ⅱ型粒细胞中有密集的细管样结构。在淡水中，各类血细胞的核膜均有不同程度的水肿现象，红细胞核略有膨胀；淋巴 |

| Abstract: | The changes of ultrastructure of the periperal blood cell of Sciaenops ocellatus under different osmotic pressure are studied using electron microscope in this paper. In sea water, the shape of erythrocyte is long elliptic and nucleus is small. There are no organs in cytoplasm. The shape of lymphocyte is irregular liscular, and nucleus is very big. It has pseugopodiums. There are few mitochondrias in cytoplasm of the monocyte. The shape of most thrombocytes looks like a teardrop or a spindle. Particle cell has two types.There are some high electron dense particles in the cytoplasm of type I. There are many tubules in the cytoplasm of type II. In fresh water, the membrance of all cells nucleus expands little or more. The nucleus of erythrocyte expands a little. The pseudopodiums of lymphocyte becomes small and there are mitochondrias in cytoplasm. There are many big mitochondrias in cytoplasm of the monocyte. There is a hollow in nucleus of the therombocyte. The particle of type I cells is big, but its number decreases and electron dense becomes lower. Mitochondrias and RER are many and big. And there are some things swallowing in vacuole. The structure of type II particle cells changes little. |
