【摘要】 应用红细胞C3b受体花环试验和红细胞天然免疫粘附肿瘤细胞花环试验方法,证实兴国红鲤(Cyprinuscarpio.var.singguonensis)、玻璃红鲤(C.carpio.var.wananensis)、荷包红鲤(C.carpio.var.wuyuanensis)及瓯江彩鲤(C.carpio.var.color)的红细胞表面都存在C3b补体受体,均可形成花环;红鲤的红细胞免疫粘附能力存在着种群间差异,上述2种花环试验的花环率大小的顺序均是:兴国红鲤>荷包红鲤>瓯江彩鲤>玻璃红鲤,差异都极显著(P<0.01);4群体红鲤的红细胞均具有吞噬作用。结果证实,鱼类红细胞免疫功能在机体防御病原的过程中占有重要地位。更多还原

【Abstract】 The red common carp of four populations were employed, which were Xingguo red common carp (Cyprinus carpio.var.singguonensis), glass red common carp (C.carpio.var.wananensis), purse red common carp (C.carpio.Var.wuyuanensis) and Oujiang color common carp (C.carpio.var.color). The tests of erythrocyte C3b receptor rosettes and erythrocyte native immune adhering tumor cell rosettes were conducted, and for each test, twenty individuals were collected in each population. The results confirm that there are C3b receptors on the surface of red blood cells in the four populations of red common carp, of which the C3b receptors can all form rosettes. But among the four populations, the adhering ability of red cell is different. The rosette percentages of both tests follow the order of Xingguo red common carp>purse red common carp>Oujinag color red common carp>glass red common carp, and the difference was highly significant (P<0.01). The red cells of the four populations are of phagocytotic ability. The conclusion is that the erythrocyte in fish plays an important role in defending antigen.更多还原
