查询词典 alkaline

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。

食品中必不可少的盐，预防甲状腺病加的碘，发面用的碱，人们吃海鱼、对虾、海带、鱼肝油、产自海洋的药品、营养品。

But the result of improvement soil translated alkaline soil into alkalier soil. Not onlu it is unavoidable and subsisted of stabilization in commix tier of gypsum, but also it destroyed direct improvement process. It is imported find what solved seepage problem of gypsum in the study. In configured duality structure of improvement soil, it needs abundance seepage gypsum in commix tier into noncommix tier in order to losing seepage capacity reduce in all deepness of improvement soil.

碱土改良过程中石膏渗漏损失最高可达到石膏施入量的40%以上，而改良结果碱土只转化为重碱化土；在石膏混合层内，它是一种不可避免的、稳定存在的且直接破坏土壤改良进程逆流；因此解决石膏渗漏问题亦是在本文研究工作中的重要发现：配置二元结构改良碱土中，正需要石膏混合层中大量石膏渗漏，以改良非石膏混合层，并使整个计划改良深度内的渗漏损失降为零。

Methods The contents of fluorides in water in and around a large size chemical factory were under monitoring. 545 workers and children living in polluted area and 75 villagers living around as control were selected to be measured such indexes as chronic pharyngitis and coryza, urine fluorine, dental fluorosis, secretory immunoglobulin A and the alkaline resistance of skin.

Several coterminous bands could be observed by PAGE of natural Eisenin Ⅰ and several coterminous peaks of Eisenin Ⅰ were also detected with MALDI-TOF-MS when the molecular weight of three main peaks are 24, 645, 25, 052 and 25, 281, separately. The amino acid composition of Eisenin Ⅰ(pI. 8) is specilized with high content of acidic amino acids and low content of alkaline amino acids; At the same time, the content of Ser and Thr are quite high and that of Lys, Met, Phe and Trp are quite low. Eisenin Ⅰ is highly homologous with serine proteases.
