产生凝集素的

MethodsRats were divided into two groups: control group and experimental group. The rats' thymus index, production of their serum agglutinin and macrophoge's phagocytic function were tested.

方法将小鼠随机分成空白对照组和复方大枣口服液组，通过对小鼠胸腺指数、血清凝集素产生及巨噬细胞吞噬机能的试验，观察口服液对小鼠免疫机能的影响。

The galanthus nivalis agglutinin is one kind of plant mannose combine agglutinin, it can integrate on the glycoprotein acceptor of insect enteron epithelial cell, and produces partial or system poisons to the insect and suppresses its growth.

雪花莲凝集素是目前与害虫治理有关且研究得比较多的一种单子叶植物甘露糖结合凝集素，能结合到昆虫消化道上皮细胞糖蛋白受体上，对昆虫产生局部或系统毒害后果，抑制害虫生长发育繁殖。

The Nature of Antibodies and the Immune Response in Rainbow Trout.

抗体是由抗原免疫后产生的，与某一抗原专一性地结合，特异性程度高；而凝集素是天然存在的，不需经过免疫而产生，能与多种抗原发生凝集反应，具有非特异性。

Different plant expression vectors had been respectively transferred into upland cotton cultivars Jinman12, Jinmian7, Xinluzao1 and Jihe321 via Agrobacterium tumfaciens transformation. These vectors carried cryIAc3 gene, which encodes Bacillus thuringiensis δ-endotoxin, under the control of chimeric OM promoter, CaMV 35S promoter, and cotton leaf curl virus RP promoter respectively; snowdrop lectin gene (Galanthus nivals agglutinin, gna) trans-regulated by rolC promoter controlled TGAla factor; and multivalent expression construct of both cryIAc3-cpti fusion gene and gna gene. A large number of transgenic plants and their progenies had been obtained.

为了提高外源基因的表达量，延缓害虫产生耐受性，本文通过将携带有分别在高效复合OM启动子，CaMV35S启动子及棉花曲叶病毒RP启动子控制下的苏云金杆菌杀虫毒蛋白基因cryIAc3；反式调节因子增强韧皮部表达的雪花莲外源凝集素(Galanthus nivals agglutinin，GNA)基因；以及同时含有cryIAc3、豇豆胰蛋白酶抑制剂基因和gna三价抗虫基因的植物表达载体，以根农杆菌介导法分别将这些表达载体导入了陆地棉新陆早1号、晋棉7号、晋棉12号和冀合321等我国西北棉花主要栽培品种，经体细胞胚再生获得了大批转基因再生植株。

The overall structure of ACF and ACF-2 are very similar, and it is also similar to that of habu Ⅸ/Ⅹ-bp and that of habu Ⅸ-bp come from Trimeresurus flavoviridis.

由于中央loop的结构交换，ACF-1和ACF-2的凝集素活力丧失，但却产生了新的活力，即结合凝血因子factor Ⅹ的活力。

These results indiacated that tranferring macrophages combinedwith cytokines could be a new adoptive immunotherapy protocol foradvanced cancer,and rTNF used in vivo locally could induce andactivate macrophages to kill tumor cells.Monocytes when activatedunderwent a series of phenotypic and functional changes includingthe expression of IL-2R which may provide an important immunoregu-latory pathway.The presence of lectin-like molecules on thesurface of monocytes and tumor cells may bring theeffector/target cells together,thus facilitating the inductionof apoptosis in target cells by triggering the production ofcytolytic factors and the modification of target of targer cell surface anti-gens.(such as HLA-DR).

综合以上结果可以得出以下结论：转输巨噬细胞并结合细胞因子的联合应用是肿瘤继承性免疫中的又一新的、有潜力的方法；抗肿瘤细胞因子rTNF可通过激活巨噬细胞在体内抑制对其不敏感的肿瘤细胞的生长；人单核细胞在一定条件下激活后，可表达IL-2R，进而一方面增强其自身对IL-2的敏感性，另一方面在体内也具有调节T细胞功能的作用；单核细胞和肿瘤细胞上存在的凝集素类受体可促使两种细胞之间在凝集素介导下相互接近，并诱发单核细胞产生细胞毒因子，以及通过调节靶细胞上表面抗原的表达，促进诱导靶细胞的细胞凋亡。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。
