These two traditional Chinese medicine has a strong antibacterial activity and, more importantly, they have an advantage that lower toxicity than traditional disinfectant drug - Formocresol, CP. In order to help in the developmentof new strategies to prevent or eliminate the infection byE. faecalis, thereby improving treatment results in endodontics and give a reference to clinical application, In this research , using traditional Drug formocresol and the current most respected calcium hydroxide ( calcium hydroxide mixed with propylene glycol ) as the conventional control, we investigated the antimicrobial activity of Chinese herbs cinnamic aldehgd and Chinese gallnut against E. faecalis in root canals in vitro.

上述两种中药都具有很强的抗菌作用，更重要的是它们作为中药具有较传统消毒药物—甲醛甲酚、樟脑酚毒副作用小的优点，本研究通过离体牙根管消毒实验，并用传统消毒药物甲醛甲酚及当前最受推崇的氢氧化钙制剂做为常规对照，对两种中药的抗粪肠球菌性能进行评价，以期探讨更有效且安全的抑制或杀灭粪肠球菌的方法，提高根管治疗的成功率，为临床应用提供一定参考。

It's a pitch that's won him more games over the last two years than any other hurler in major league baseball, a pitch that's turned him into the ace of the most famous sports franchise in the world.

这个球种让他在过去二年赢得比其他在大联盟中的投手更多的胜场数。这个球种让他成为全世界最有名的运动集团的王牌投手。

Based on data collected at four stations in Daning River in the spring of 2004 and 2005, phytoplankton community structure, vertical distribution, abundance, biomass, C contents, diversity index, richness index and evenness index were studied. The causes of eutrophication and water blooms in Daning River were analysed and control measures were then put forward. The dominant species were Asterionella Formosa, Cryptomonas ovata, Cyclotella caspia, Stephanodiscus neoastraea in the spring of 2004 and those were Pandorina morum, Eudorina elegans, Cyclotella caspia, Cryptomonas ovata in the spring of 2005. Average cell densities, biomass, C contents in the spring of 2004 and 2005 were 171.1×10^5 cells/L, 12.2 mg/L, 1732.2g C/L and 113.1×10^5 cells/L, 10.1 mg/L, 1395.9g C/L, respectively.

报道了大宁河2004年春季和2005年春季浮游藻类的种类组成、垂直分布、数量、生物量以及C含量的调查结果，并应用多样性指数、丰富度指数和均匀性指数对其水质进行了综合评价；对大宁河蓄水后出现的富营养化现象和春季发生&水华&的原因进行了探讨，同时提出了控制水体富营养化的建议。2004年春季，藻类优势种为美丽星杆藻、卵形隐藻、里海小环藻和新星形冠盘藻；2005年春季的优势种为实球藻、空球藻、里海小环藻和卵形隐藻。2004年和2005年的细胞密度、生物量和C含量分别平均为171.1×10^5 cells/L，12.2 mg/L，1732.2g C/L和113.1×10^5 cells/L，10.1 mg/L，

To identity the strains of Eimeria conserved in our laboratory are purebred,11 strains of 6 Eimeria species were separated by single-oocyst method and infected chicken of 1—5 days old.

为了建立鸡球虫纯株，选用1~5日龄雏鸡，采用琼脂块单卵囊分离法对实验室保存的6种11株鸡球虫进行纯化，并选用2周龄雏鸡，对每个虫种/株选取1个单卵囊分离物进行增殖和种类鉴定。

On the basis of the ligamental reticulated carbon foam by Klett J W in 2000 and hollow microsphere carbon foam by Bruneton E in 2002, a hollow microsphere/ reticulated composite carbon foam was prepared by microstructural optimization, carbonization and graphitization respectively.

在Klett J W等人于2000年制备的韧带网络型碳泡沫和Bruneten E等人在2002年制备了一种空心微球碳泡沫材料结构的基础上，分别经过微观结构优化、碳化、石墨化处理，制备出了一种空心微球/网络复合型碳泡沫材料。

Micrococcal lysis assay of the milk samples showed that the cDNA was efficiently expressed in the mammary glands with similar expression levels ranging from 60 to 87 mg/L. Different tissues of each vector-injected mouse were assayed for transcription of hLYZ mRNA by dot-blotting and for expression of hLYZ activity by Micrococcal lysis assay. The results showed that expression of the three recombinant vectors was mainly restricted to mammary glands with some degrees of ectopic expression in spleen, intestines and/or kidney.

注射后72 h采集乳样，经微球菌溶解实验证明，3组小鼠乳汁中hLYZ的表达量分别为87、69、60 mg/L；从每组小鼠的12种组织提取总RNA，经Dot blotting检测证明，三种重组载体除在乳腺中表达外，p205C3LYZ还在小鼠的脾和肠、pBJLYZ在脾、pBCLYZ在脾和肾中具有一定的异位表达；在有hLYZ mRNA转录的上述脏器中用微球菌溶解试验均可检测到hLYZ活性。

One half of the ball may be made from one type of foam and the other half of the ball may be made from another type of foam.

球的一半由一种泡沫材料制成，而球的另一半由另一种泡沫材料制成。

Ball two, one is a floating ball valve, which can be a floating ball in the valve chamber, relying on both ends of the compression ball and stable sealing seat.

球阀有两种，一种是浮动球阀，即球体在阀腔内可浮动，依靠两端的密封座压紧球体而稳定。

Valve type Use the search for a match with the valve, should first look at four kinds of basic types of throttle control valve, that is, cage ball, rotating ball valve, eccentric butterfly valve and valve.
