菌毛

Results It showed that there was only one 31ku band,which indicated that the fimbriae of actinomyces viscosus 5951 was composed of the same subunits of 31ku molecular weight.

结果 显示分子质量为31ku一条单一的色带，表明粘放菌5951菌毛是由相同的分子质量为31ku的亚基组成。

We also discovered that selenium can decrease hematolysis and effects function of vacuole toxin of HP. morphological conversion from spiralto coccoid forms occurredwhen HP was caltured with selenium and most of coccoid forms had fragmentary flagella and pilus; the effection of selenium to activity of urease, catalase, alkaline phosphatase is not exist or not evidence; selenium enable pET32a-vacA-E. coli BL21 which can express VacA produce yellow lipochrome, and the color become deeper with increasing of concentration of selenium; selenium can decrease expression of recombined VacA by restrain the growth of pET32a-vacA-E. coli, but can not influence activity and gene equence of VacA; selenium can enhance the suppression effect of recombined VacA for gastric cancer cell, depress the index of cell multiplication and the forming rate of colony, decrease the number of cell in S period, increase total of cell in G period; After purified, the recombined VacA can be identified by VacA antibody.

结果：体外实验结果表明：一定浓度的硒作用HP后，HP菌落数量随着硒浓度的增加而减少，菌落颜色由灰白色变为砖红色，溶血现象随硒浓度的增加和作用时间的延长而逐渐消失，HP的形态由弯曲形变为球形或椭圆形，鞭毛及菌毛出现脱落现象；硒对尿素酶、过氧化氢酶、碱性磷酸酶活性无影响或影响不明显；一定浓度的硒能使表达VacA的pET32a-vacA-E.coli BL21工程菌产生脂溶性砖红色色素，颜色随硒浓度增加而加深；一定浓度的硒通过抑制pET32a-vacA-E.coli BL21工程菌的生长，减少重组VacA表达量，但不影响其空泡毒活性及编码基因序列；硒能增强重组VacA对胃癌细胞的抑制作用，使细胞分裂指数和集落形成率降低、S期细胞数量减少，G1期细胞总数增加；纯化后的VacA重组蛋白可被VacA抗体识别，具有良好的抗原性。

These data indicate that hCD46 is a kind of crucial pilus receptor that mediates the host specific adhesion by N. gonorrhoeae, and the hCD46 minigene, pCD46, can be used to develop transgenic mice model for the study of gonococcal diseases.

提示hCD46是菌毛介导的淋病奈瑟菌特异性黏附于人黏膜细胞的一种重要受体，hCD46小基因可用于淋病奈瑟菌感染转基因小鼠模型的制备。

Methods Four pairs of primers were designed from toxin sub-unit A gene, O139 special gene, Haemolytic subunit A gene and Toxin coregulated pilus subunit A gene. Multiplex PCR was established to simultaneously detect those four genes.
