Blastomyces albicans is a kind of dimorphism fungus which includes yeast phase and hypha phase The cell wall is rich of β-glucans which can be recognized by phytohemagglutinin-like inherent immunity receptor Dectin-1, induce phagocytosis and bactericidal action of phagocytes and cytokines release.

白色念珠菌是以酵母相和菌丝相存在二态性真菌，其细胞壁富含葡聚糖，葡聚糖可被植物凝集素样固有免疫受体Dectin-1识别，引发吞噬细胞的吞噬和杀菌作用，并释放大量细胞因子。

This paper reports the results of preliminary study on the specificity of red blood cell antigens from varieties of carp (Cyprinus carpio L.).

用血球凝集和血清吸收试验的方法，对若干个鲤鱼品种及鲤鱼人工雌核发育系的红血球中的某些同种异型抗原纯合性进行了初步研究。

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。

Swine enteropathogenic E. colis were rejuvenescenced and 6 of them were selected to prepare blood serum. We had tested the reactance of cross agglutination and agar diffusion between the strains and the blood serums. No. 300 and No. 343 were selected because they had highly cross reaction. To test superantigen of No.300 and No.343, the antigens made by both of them immunized piglets, and then we detected the serum 0D values with indirect ELISA. The OMP and PF of No. 300 and No. 343 were extracted for SDS—PAGE and westen-blotting.

本研究针对10株猪致病性大肠杆菌，经复壮后选取致病性强的6菌株作为供试菌株，制备免疫血清与这6菌株的多种抗原分别进行交叉凝集试验和琼脂扩散试验，根据各菌株抗原的交叉反应程度，筛选出抗原交叉程度高的菌株300和343，检测两菌株超抗原的毒性作用，以不同方式制备抗原免疫仔猪，用间接ELISA检测免疫效果，并提取菌株300和343的外膜蛋白和渗透因子经SDS—PAGE及免疫印迹试验，进行相关分析。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。
