METHODS: The bile was treated with 3 different methods, including the 2D-Clean-up kit group: the bile sample was dissolved with lysis buffer (contains: 7 mol/L carbamide, 2 mol/L thiourea, ammonium persulfate with mass concentration of 0.4 g/L, 65 mmol/L dithiothreitol, carrier ampholytes with mass concentration of 0.2 g/L).

将标本分别按3种不同方法进行处理：①2D-Clean-up试剂盒处理胆汁标本：用裂解液，7 mol/L尿素，2 mol/L硫脲，质量浓度为0.4 g/L的过硫酸铵，65 mmol/L二硫苏糖醇，质量浓度为0.2 g/L的载体两性电解质溶解沉淀过夜。

In conclusion, our studies indicated that, by reducing the concentration of corticoid, increasing the GH concentration, dietary glutamine could maintain the N balance in the body, induce the intestinal glutamine extraction from blood, maintain the glutamine store in muscle tissue and plasma, decrease the glutamine flux from muscle tissue and protein catabolism. As the key fuel of intestinal mucosa and lymphocytes, exogenous glutamine maintained the intestinal structure, function and the CD4〓/CD8〓 ratio. In addition, glutamine normalized the SIgA containing cells'quantity and distribution through stimulating the IL-6 gene expression.

综合分析本研究的试验结果，我们认为，日粮中的外源性Gln可通过降低断奶应激后血清中皮质醇浓度，升高生长激素的浓度维持体内N的平衡，降低肠粘膜细胞从血浆中摄取的Gln，减少骨骼肌蛋白质的分解，维持骨骼肌和血浆中Gln浓度，维持淋巴细胞亚群中CD4〓/CD8〓比例；提供肠粘膜细胞能源和代谢的前体，维持肠粘膜正常的屏障结构和功能，通过刺激IL-6的表达，维持肠粘膜中SIgA分泌细胞的数量和肠道的局部免疫功能，并最终提高断奶仔猪的生产性能和抗病能力。

A simple and efficient method for concentration of enteroviruses from water sample was established based on the membrane adsorption-elution method combined with eluant concentration.

文章摘要：在膜吸附-洗脱和洗脱液浓缩相结合的基础上，建立了一种简便实用的水中肠道病毒浓缩方法，通过实时定量RT-PCR检测，比较了不同材料和不同孔径的微孔滤膜对病毒的吸附效果；对膜洗脱方式进行了改进；研究了在洗脱液浓缩过程中，PEG浓度对于病毒回收率的影响。

Kidney stones form when the concentration of calcium in the kidney tubules gets to a critical concentration.

肾结石形式时，钙的浓度在肾小管进入一个关键的浓度。

The observation and monitoring were carried out for one year. Improvements resulted from the project include suspended particles, transparency, concentration of chlorophyll A, total organic carbon, total nitrogen. Factors that did not show obvious improvement include electrical conduction, concentration of nitrate nitrogen, ammonia nitrogen, nitrous nitrogen, phosphate salts. Finally, factors that were influenced by environment include water level, temperature, pH, total phosphorus, chloride salts.

历经一年的试验，因设备投入而改善之因子为溶氧、浊度、悬浮固体、透明度、叶绿素a、总有机碳、总氮等7项，无明显变化之项目为导电度、硝酸盐氮、氨氮、亚硝酸盐氮、磷酸盐等5项，受环境影响因子为水位、水温、pH、总磷、氯盐等5项。

It's result that the parameters for good performance should be as follow:17% the concentration of PS,5% the concentration of PVP,20S for pre-evaporation time and 4% DMAC contration in the coagulation bath.

此次实验结论是在聚砜含量17%，PVP含量5%，预蒸发时间20S和凝固浴浓度4%的条件下，制备出的聚砜平板膜的性能良好、表面具有较高孔隙率。

Furthermore, the structures of DNA molecules varying with concentration of new modification agent were studied, and it was found that when the new modification agent concentration was 1:1000, DNA molecules were successfully fixed and extended on the modified mica surface and well-distinguished DNA strands were imaged by AFM.

并进一步观察了不同DAPS浓度下DNA分子的吸附行为，发现当DAPS/甲醇体积比浓度为1：100时，DNA分子呈现出大而复杂的形态，发生了分子内和分子间的碱基相互配对；当体积比浓度为1：3000时，即没有分子内和分子间的碱基相互配对，也

The concentration of sodium tungstate impacts on the activation energies notably. The activation energies increase the concentration of sodium tungstate is improved.

研究取得以下成果： 1在化学镀Ni-Co-P磁性薄膜的配方中添加钨酸钠可以显著提高沉积速率和镀膜的磁性能。

In the solution,low concentration sulfate ions was determined by a direct titration with barium perchlorate as titrant and thorin as the indicator;the concentration of calcium ions was determined by a direct EDTA titration using Calcon carboxylic acid sodium salt as the indicator.

先用高氯酸将固体混合物溶解形成水溶液，然后以钍试剂为指示剂，用高氯酸钡溶液滴定溶液中的微量硫酸根，并用EDTA法以钙红为指示剂滴定溶液中的钙离子，从而可以计算出钙基脱硫剂的固硫率(表示为脱硫后固体混合物中的钙硫化)。

"If you drink too much water it lowers the concentration of salt in your blood so that it is lower than the concentration of salt in cells," says Professor Robert Forrest, aconsultant in clinical chemistry and forensic toxicology atthe Royal Hallamshire Hospital in Sheffield.
