Agglutinin activity in hemolymph of Chinese shrimp and induction effect of Vibrio

Experiments showed the agglutinin activity in the hemolymph of both spring wild parents and autumncultured individuals of the shrimp Penaeus chinensis Osbeck with the body length of 12 - 16 cm as all 32. Thehemolymph of the above shrimps showed agglutinant reaction to all A-, B- and O-type human erythrocytes, with thereaction titer equal to that of rabbit blood cells. However, the agglutinin activity level was enhanced after being in-duced by Vibro, which was 128 after 24 h of induction and reached the peak value 256 after 48 h of induction, thendecreased gradually.

中国对虾血淋巴液中的凝集素

用饱和硫酸铵盐析、S 2 0 0 HR凝胶层析、DEAE sepharose离子交换层析从中国对虾 (Penaeuschi nensis)血淋巴液中分离出 1种凝集素 ,通过SDS PAGE测定 ,该凝集素由 2个亚基组成 ,分子量分别为80 0 0 0、750 0 0 ;此凝集素能凝集牛、马、鼠、兔、鸡、羊和人A、B、O型红细胞 ,其凝集活性不被D 甘露糖、D 果糖、D 乳糖、乙酰半乳糖、神经氨酸、D 葡萄糖、D 半乳糖和D 岩藻糖抑制 ;其最适血凝 pH为 6～ 8,Ca2

中国对虾血淋巴凝集素的血凝活性与促噬活性

１９９９年８月，运用血凝活性测定法分别检测中国对虾血淋巴凝集素、血淋巴液、血细胞、肌肉、肠、肝胰腺和甲壳的血凝活力，并运用■啶橙血细胞吞噬测定法检测血细胞的吞噬活力，同时测定了经注射中国对虾副粘病毒提纯液后血淋巴凝集素血凝活力及血淋巴液抗菌活力、酚氧化酶活力、溶菌活力。结果表明，血淋巴凝集素主要分布在血淋巴液和血细胞中；该凝集素对人（Ａ、Ｂ、Ｏ型）、鸡和兔红细胞及其醛化红细胞的凝集具有一定专一性；对血细胞吞噬异物具有促进功能；注射副粘病毒提纯液后，血淋巴凝集素凝集活力变化和血淋巴液抗菌活力、酚氧化酶活力。溶菌活力变化相一致。
