The inhibitory effect of the volatilizable metabolites of two antagonists to P.funerea was analyzed in contrast with the inhibitory rate of the control . Gvirens , with the highest inhibitory rate of 59.7%, had more excellent and stable inhibitory activity and the effect was more relative with the time, but the inhibitory rate of B.firmus was less relative with the time and the inhibitory effect of B.firmus became stable after 72 hours.

两种颉抗菌代谢物中不同成份的抑菌效应试验表明，G.virens产生的多糖、粗脂肪、蛋白质对P.funerea孢子萌发有抑制作用，粗脂肪、蛋白质更明显，其中蛋白质抑制效果较稳定；B.firmus产生的粗脂肪可完全抑制P.funerea的孢子萌发，多糖、蛋白质抑制效果也较稳定，但多糖效果更好。

Results After injection before examination,heart rate and blood pressure decreased temporarily in most of patients of group A(P.05).While there was a conspicuous increase in heart rate and blood pressure in the patients of group B(P.05).There was no pain or discomfort in the patients of group A.The phenomena such as nausea and vomition,begma could be found in most of patients of group B.

结果 A组患者在给药后呈一过性心率的减慢、血压降低(P.05)，镜检中无明显的不适反应；B组大多数患者镜检过程中心动过速、血压升高(P.05)，出现了不同程度的恶心、呕吐、呛咳等不适反应。

The electric potential difference UAB between points A and B in an electric field is equal in strength to the work WAB done on a positive unit charge moved form A and B.

电场中AB两点间的电势差等于把单位正电荷从A点移到B点电场力所做的功。

Results: Wallerian degeneration was observed in the proximal and distal ends of all grafts of nerves harvested at 2 weeks post-engraftment; infiltration of T lymphocytes at the grafts in group B was significant, less T lymphocytes were seen in group C, D and E, while no T lymphocytes were seen in group A and F.

结果：术后2周，所有移植段近端，移植远端神经均有不同程度Wallerian变性，B组移植段见明显T淋巴细胞浸润，C，D，E组次之，A组及F组未见T淋巴细胞。B组以大量成纤维细胞增生为主，A，F组以SC增生为主，C，D，E组介于两者之间。

Therefore, it is important to ask whether both Oct-2 and NF-κB participate the MEK/ERK dependent G-CSF expression. G-CSFp-(-289~+25)-Luc, CSF-box-deleted G-CSFp-(-145~+25)-Luc, or octamer-mutated Oct-mut-G-CSFp-(-289~+25)-Luc reporter plasmids were used to investigate the importance of CSF-box and octamer in response to LPS.

在G-CSF的启动子上有两段已被发现对其活性相当重要的序列：CSF-box及octamer，根据过去研究及本实验室未发表的实验结果，此两段序列分别由NF-κB以及Oct-2所结合；於是我们推测MEK/ERK讯息传递路径的下游可能透过NF-κB及Oct-2来调控G-CSF表现。

A and B isomers could interconvert each other by an inversion of the imine nitrogen atom. In this work, we investigated the substituent effects and solvent effects. This study used the most popular one of density functional theory method unrestricted hybrid Becke three-parameter Lee-Yang-Parr (B3LYP) with the 6-31+G basis set to compute the reaction and activation energies of B/A thermal isomerization.

腙分子的异构化过程藉由转动亚胺基上的氮原子，使腙分子由A 型结构转变成B 型结构(Scheme1)，本研究运用密度泛函数理论中最常被使用的B3LYP，搭配6-31+G基底函数，计算腙分子异构化过程的活化能以及反应热，并且考虑取代基与溶剂效应对能量所造成的影响。

The diblock copolymer of styrene and chloromethyl-4-vinyl-benzene was obtained by means of reverse addition fragmentation chain transfer reaction living free radical polymerization. The chloromethyl groups in PS-b-PCVB were transformed into azidomethyl groups, and then into 1,2,3-triazol groups via click chemistry. The diblobk copolymer containing 1,2,3-triazol groups was thus obtained. The results from NMR spectra suggested a complete transformation from chloromethyl groups to triazol groups.

通过可逆加成－断裂链转移聚合活性自由基聚合方法制备了聚（苯乙烯－b-对氯亚甲基苯乙烯）二嵌段共聚物，其中的氯亚甲基侧基经叠氮化反应后与丙炔醇进行点击反应，最终得到了含有1，2，3-三氮唑官能团的聚苯乙烯二嵌段共聚物，核磁共振谱表征结果证明，PS-b-PCVB中的氯亚甲基完全转变成了1，2，3-三氮唑基团。

In addition, we found that 4-phenyl-l,2,4-triazolinium N-ylides reacted withvarious electron-deficient olefins to afford pyrrole derivatives in good yields via 1,3-dipolar cycloaddition oxidative ring fission, In some cases, tetrahydropyrrolo[1,2-b]triazole and pyrrolo[1,2-b]triazole, which are stable and are not aromatized orcleaved in the reaction conditions, could be isolated, This is a facile and novel route forthe synthesis of pyrrole derivatives.

此外，本文研究了五员三氮杂环化合物4-苯基1，2，4-三氮唑的N-叶立德，发现在氧化剂存在下与缺电子烯烃发生1，3-偶极环加成反应生成的吡咯并[1，2-b]三氮唑，在大多数情况下开环生成吡咯衍生物，反应条件温和，收率良好，是合成吡咯衍生物的一个新的途径。

If only enough rope is available for a belay from one bank, A crosses as above. C ties into the main belay rope and also ties on alight retrieving cord held by Band is belayed by A. This retrieving line is necessary since it would probably be impossible to throw the rope back to B after C crosses.

如果绳子的长度只够从一边作确保，A仍像上述过溪，C要套入胸部绳圈中由A作确保工作，同时要有另外一条回收绳连接到B手上作主绳的回收工作，这条回收绳是必要的因为C过溪之后几乎不可能将主绳抛回去给B。

Methods 414 patients who underwent ERCP were divided at random into 3 groups; group A (n=158) receiving perioperative intravenous cimetidine, 800mg/day for 3 days; group B (n=147) having hypodermic octreotide, 0.1mg, 30 minutes before and 4 hours after ERCP; group C (n=109) being given boluses of placebo.

方法将414例患者随机分为A、B、C三组，A组(158例)分别于术前一日、当日及术后一日给予西咪替丁(800mg/d，静脉滴注)，B组(147例)分别于术前30min及术后4h内给予生长抑素类似物奥曲肽0.1mg皮下注射，C组(109例)给予安慰剂。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""
