歧化

We designed primers according to the sequence of Genbank from Bifidobacterium breve and have cloned the putative isomerasekey gene and several fragments from the genome DNA of Lactobacillus acidophilus .

Firstly, normal mice was given orally by SM(qd×2d), and the dysbacteriosis were caused in them ,and then they were given orally by STM,these mice were formed experimental salmonellosis models ,finally these salmonellosis models were treated by bifidobacterium ,and count respectively the cfu/g of STM number in the mice excrement during different time of therapy,detect the index numbers of liver and spleen respectively, detect content of TNF-a in blood and in spleen respectively.

先用硫酸链霉素给正常小鼠灌胃2d，出现菌群失调症状，再用STM灌胃造成小鼠STM感染，使用两岐双岐杆菌液干预治疗STM感染小鼠，检测不同治疗时间各组小鼠粪便STM菌落数、肝脾指数、血及脾中TNF-a的含量。采用SPSS12.0统计软件包进行数据处理分析，统计学方法采用双因素重复测量资料的方差分析、单因素随机化设计的方差分析、卡方检验、多组均数比较的非参数秩和检验。结果：随着治疗天数的增加，STM菌落数逐渐减少，未干预组、生理盐水组及双歧杆菌组比较结果均为P＜0.01；组间比较，双歧杆菌组STM数下降最快。

The levels of SOD and CAT significantly increased and MDA decreased in bifidobacterium group compared to radition damage group.Electronic microgragh of spine neurocyte and neurogliocyte showed that cytoplasm,cytoblast and plastiosome were significantly engorged ,and neurogliocyte apoptosised in earlier period. TLR2mRNA increased in C group compared to B group by RT-PCR. Cytochrome C in kidney increased in C group compared to B group, but bcl-2,NF-Кb decreased. Conclusions : Enteroclysm is better compared to intragastric administration.

双歧杆菌处理组肝组织中SOD和CAT水平明显高于放射损伤组(P.01)，同时MDA明显低于放射损伤组(P.01)；电镜结果显示：放射损伤组与双歧处理组的细胞浆、细胞核和线粒体均明显肿胀，双歧处理组同时具有早期凋亡现象；RT-PCR结果显示：双歧处理组TLR2mRNA的表达明显高于放射损伤组；免疫组化结果显示，双歧处理组Cytochrome C的表达明显优于放射损伤组，而NF-кBp65和bcl-2则相反。

Herbs, annual or perennial. Stem sometimes woody at base, simple or dichotomously branched.

一年生或多年生草本茎有时在基部木质化，简单或二歧分枝。

Proteomic comparison of glucose- and lactose-grown cells revealed that lactose and glucose were catabolized via the same degradation pathway, and the rate of glucose assimilation was higher than that of lactose.

长双歧杆菌NCC2705在乳糖中生长快于葡萄糖，它们的降解途径是相同的；转醛缩酶和丙酮酸激酶发生了翻译后修饰作用，推测转醛缩酶在43T和47S发生了磷酸化，而丙酮酸激酶在65S发生了磷酸化。

Obtained by is omerizing gum rosin with a catalyst , mainly consists of dehydroabietic acid , important component for making potassium soaps , raw material for adhesives and chewing gum .

歧化松香是一种改性松香，主要成分是去氢枞酸。性能稳定，常制成钾皂，用作合成橡胶的乳化剂，以改善和提高橡胶性能，也是制造胶粘剂及口香糖的重要原料。

The conversion of the high-boiling components and low-boiling components of silane to valu- able methylchlorosilane by catalytic cracking and disproportionation catalyzed by acid treated active carbon andγ-Al_2O_3 was studied.

用酸处理的活性炭和γ-Al_2O_3组成双段催化剂，通过有机硅高沸物和低沸物的裂解歧化反应制备了甲基氯硅烷，考察了反应温度、质量空速等因素对反应的影响。

The results prove that in pulse radiolysis experiments a Cu intermediate may also be involved and will give a clue to the mechanism of toxicity of 〓.

该结果为配合物在歧化〓的过程中被氧化成Cu提供了证明，并且为〓在生物体内的毒害来自于其氧化性提供了新的佐证。

The results indicated that the adsorbance of adsorbed CO in the presence of alkali and rare-earth metal oxide decreased, and thus suppressed the nick loss in the form of Ni〓 in the POM process.

CO-FTIR的结果表明，锂和镧的添加可明显减少CO在NiO/γ-Al〓O〓上的吸附，从而抑制反应过程中羰基镍的生成和流失，同时也抑制了CO的歧化积碳和在表面进一步氧化成CO〓。3。

The main component dehydroabietic acid and little component abietic acid, neoabietic acid, levopimaric acid and pulustic acid of a few types disproportionated rosin were determinated quantitatively by selecting the proper order of derivative, differential wavelength difference, scanning rate and quantitative method.

通过选择合适的求导阶数、微分波长差、扫描速度和定量方法，对不同批号的歧化松香中的主成分脱氢枞酸和微量组分枞酸、新枞酸、左旋海松酸及长叶松酸进行了测定(其中左旋海松酸和长叶松酸测定的是合量)，实验结果令人满意。
