Results: There was high detectable rate of Salmonella serotype Derby. Salmonella serotype Agona, and Salmonella serotype Anatum, in both kinds of specimens except high detectable rate of Salmonella serotype Typhi in clinical specimens. Group B of Shigella was the most and Group D took second place. While S. flexneri 2a was detected mostly and 2b was the second.

结果：检出的沙门菌血清型中除临床标本中检出的较多的伤寒沙门菌外，德尔卑沙门菌、阿贡纳沙门菌、肠炎沙门菌和鸭沙门菌在两类标本都有较高的检出率；志贺菌都以B群居多，D群次之，B群中以福氏2 a型检出率最高，2b型次之。

As a continuation of our previous research on syntheses of tetrahydrofuro[3,2-b]furan-1(5H)-one, Dr. Zhang Yi-Jun started the total synthesis of pallavicinin B in 2002, and made strategic achievement in building the bicyclo[3.2.1]octane skeleton.

基于我们小组多年来对具有四氢呋喃并γ-丁内酯子结构的天然产物全合成研究的兴趣，从我们小组张怡隽博士就已经开始了pallavicinin B的全合成研究，并取得了阶段性的进展：成功构建了骨架中下半部的二环[3.2.1]辛酮。

The layers can increase obviously the destiny of microstructure, magnetic properties Br, Hcb, m and compressive strength of the NPMC bonded by plastic. The epoxy coating can improve effectively the corrosion resistance of the NPMC and delay the rust of NdFeB particles, especially the pycno-film of the cathodal electrophoresis epoxy resin plays a dominant role in the achievements. The investigation of the temperature stability of the NPMC bonded by plastic, whose NdFeB magnetic particles are NFZ-1 and Nd〓Fe〓B/α-Fe,〓 made in China, shows that their ergo-temperatures vary with their components.

环氧树脂涂层能有效地改善塑料粘结NdFeB永磁复合材料的耐蚀性，延缓锈蚀的发生，特别是致密的阴极电泳环氧树脂涂层对塑料粘结NdFeB永磁复合材料具有更为优异的防腐作用；国产的NdFeB磁粉（NFZ-1和Nd〓Fe〓B/α-Fe、〓）制成的塑料粘结永磁复合材料的温度稳定性的研究表明〓纳米晶合金制成的塑料粘结永磁复合材料使用温度应不超过100℃，NFZ-1制成的塑料粘结永磁复合材料可在120℃以下工作，Nd〓Fe〓B/α-Fe制成的塑料粘结永磁复合材料可在140℃以下工作。

Immunohistochemistry stain shows: A lot of positive express of NF-κB were found in the cytoblast and endochylema of operated group plantaris and the activity express of iNOS wasn't found in control.

3免疫组化结果显示：正常对照组骨骼肌细胞基本无NF-κB表达，实验组骨骼肌细胞可见胞核及胞质大量NF-κB表达。

The cows were detected with B-mode ultrasound scanner with a 5.0 MHz linear probe designed for intrarectal placement at 30 days after insemination.

使用AMI-900型便携式兽用B超诊断仪的5.0MHz的线阵探头，通过直肠对配种后30d的母牛进行了妊娠探查，主要目的是探讨B超在生产应用中对肉牛早期妊娠诊断的适用性和意义。

According to one conserved sequences of phage GIL01 from Bacillus thuringiensis,a pair of primers was designed.With overnight cultivations of 35 B.t standard strains and one fermentative strain MZ1 as templates,PCR results showed that 16 strains,which may be lysogenic strains,produced the product with the size about 750 bp as anticipated.

根据苏云金杆菌(Bacillus thuringiensis， B.t)溶原性噬菌体GIL01(GenBank Accession Number： AJ536703)的同源序列设计一对引物，用35株B.t标准菌株和生产菌株MZ1(血清型H3a3b)的过夜培养物作模板，结果有16株菌株包括MZ1能扩增出大小约为750 bp的预期产物，推测这16株菌为溶原菌。

Activated NF-κB was a restricted step of pancreatopathy; PKC inhibitor could limit the activation of NF-κB by restraining activation of PKC, then attenuate the cytokine releasing and alleviate inflammatory reaction.

应用蛋白激酶C抑制剂，通过抑制蛋白激酶C的激活，能阻断NF-κB的活化，减少细胞因子的过度释放，减轻炎症反应。

It is found that there is a co-relationship between the boron isotope and chemical composition of magmatic tourmaline: the δ〓B value increases with increasing Al and Li in Y-site of tourmalines. The low δ〓B values (-41. 1～-39. 01‰) in Altay No. 3 pegmatite, which is one of the lowest values found by now, imply that non-marine evaporites might exist in magma source, or the pegmatitic magma had been assimilated by them during its intrusion and emplacement.

阿尔泰3号伟晶岩最初形成的结构带中电气石的B同位素组成是目前所发现的最低值之一(-41.11～-39.01‰)，指示形成伟晶岩脉的初始岩浆可能由含非海相蒸发岩的泥质岩经变质深熔作用形成，或是伟晶岩岩浆在上侵定位过程中同化了含非海相蒸发岩地层的结果。

Western blotting confirmed that the low activity of b-lactamase in E. coli Top10 pcs+ resulted from a lower amount of b-lactamase in its periplasm.

由此可见，周质内低含量的b-内酰胺酶是导致E.coli Top10 pcs+细菌氨苄青霉素抗性降低的原因。

Objective To establish a sensitive and specific gene probe method for detection of Staphylococcal enterotoxin B gene.
