| 摘 要： | 利用电镜技术观察海水鱼类牙鲆鳃小片的基本结构及其免疫相关细胞的分布和形态。牙鲆的鳃小片主要由扁平上皮细胞和柱细胞构成 ,血窦腔极为发达。鳃小片在功能上可分为两个区 :气体交换区和免疫区。气体交换区位于上半部分 ,血窦内主要分布着红细胞 ;免疫区位于鳃小片基部 ,血窦腔中分布着各种免疫相关细胞 :淋巴细胞、单核细胞、中性粒细胞和酸性粒细胞。此外 ,还观察到了泌氯细胞和粘液细胞。研究结果证明 ,牙鲆的鳃在局部粘膜免疫中具有重要的作用 ,是鱼类免疫体系中的有机组成成分之一

| Abstract: | The gill lamella structure and its immune cells of Bastard Halibut, Paralichthys olivaceus (Themminck & Schlegel) were observed by transmission electron microscope. The gill lamella was composed of squamous epithelium cells and pillar cells. The blood sinusoid cavity was very large. Functionally, the gill lamella could be divided into gas exchange region and immune region. Gas exchange region located in the upper half with many erythrocytes in the blood sinusoid, while the immune region located in the lower half with lymphocytes, monocytes, neutrophils and eosinophils granule cells in the blood sinusoid. Moreover, the chloride secreting cells and mucous cells were also observed. The results showed that the immune cell types existing in the gill tissue were completed and they might play some extent roles in the fish local immune competence. |
