Methods: This paper investigated the changes of serum protein sulfhydryl and non-protein sulfhydryI of children suffering from cold, diarrhea and pneumonia.

观察小儿上感、腹泻和肺炎时血清蛋白巯基和游离巯基的变化。

A higher level of sulfhydryl compounds wasobserved as fruit stored at low temperature.

低温贮藏时果实组织虽保持较高的巯基化合物水平，但巯基化合物DTT处理并不影响荔枝褐变的进程。

Results show that, by using thionyl chloride and N,N-dimethyl formamide as chlorinating reagent and dichloromethane as solvent and taking -15℃ as reaction temperature, Z-iomer crystals with pale white color and stable to temperature can be obtained with an overall yield of 70%.

以2-（2-氨基噻唑－4-基）－2-甲氧亚氨基乙酸为原料，经盐酸化、氯代等反应合成了Z-2-（2-氨基噻唑－4-基）－2-甲氧亚氨基乙酰氯盐酸盐；氯代时以用亚硫酰氯和N，N-二甲基甲酰胺的混合物代替五氯化磷作氯化剂，并考察了温度和溶剂对氯代产物中Z-异构体和E-异构体收率的影响。

Cinnabarinus at 150 mg/L.The influences on bioactivity of substituted pyrazole and pyrimidine were discussed respectively: pyrazoles substituted with phenyls at 3 position had higher activity than thiophen and compounds with R_1=methyl had higher activity than that with R_1= hydrogen, pyrimidines substituted with methyl at 2 (R_3) and 5 (R_3) position and phenyl at 6 position were most active.

本论文对吡唑及嘧啶取代基对活性的影响分别进行了讨论，可知：吡唑3位为取代苯基的化合物杀菌活性优于取代噻吩的，吡唑4位(R_1)为甲基的杀菌活性高于R_1为氢的活性；嘧啶的2位(R_3)为甲基，5位(R_1)为甲基，6位为无取代基的苯基时活性最好。

Its beneficial widespread effect on health is attributed to sulphur compounds and particularly to thiosulfinates. Odorless and stable, alliin is the most abundant sulfur compound in whole, unbruised Garlic. When the clove of garlic is cut or crushed, the enzyme alliinase is released from its compartment and transforms S-allyl-L-cysteine sulfoxide or alliin into diallyl thiosulfinate allicin, the characteristic compound of garlic flavor. This very unstable thiosulfinate is rapidly degraded to related organosulfur compounds. Allicin is often thought of as the "active ingredient" in Garlic, and has been the subject of numerous scientific studies, but its a fairly unstable compound that likes to react with itself.

蒜氨酸(S-烯丙基-L-半胱氨酸亚砜，alliin)是完整、未受损大蒜里面含量最丰富的硫化物，并且非常稳定，它存在于大蒜的细胞质里；当细胞受损时，蒜氨酸酶从细胞液向细胞质释放，蒜氨酸和蒜氨酸酶接触被迅速转化为一系列新的化合物—蒜辣素及其相似物，蒜辣素(双烯丙基硫代亚磺酸酯，allicin)被认为是大蒜中最重要的活性成分，但它相当不稳定，易于自身反应。

The obtained results show that the primary and secondary alcohols areconverted in good yields, whereas tertiary alcohol and phenol are unreactive.

当原料分别为乙醇、正丁醇、仲丁醇、苯甲醇和苯乙醇时，目标产物碳酸二乙酯、正丁基乙基碳酸酯、仲丁基乙基碳酸酯、苯甲基乙基碳酸酯和苯乙基乙基碳酸酯的产率分别为67.3、52.3、56.7、37.6和32.8％。

To understand the reaction of tetrakis hydroxymethyl phosphonium chloride with collagen protein,the interactions of THPC with polycaprolactam,poly vinyl alcohol or ethylenediamine which were used as the model substances of amido,hydroxy and amino groups of collagen protein were examed.

通过研究THPC与聚己内酰胺、聚乙烯醇、乙二胺的酰胺基、羟基、氨基的反应，间接证明THPC主要与胶原蛋白的氨基结合，可与氨基以n∶n=1.0∶2.2形成交联，THPC与羟基和酰胺基均有少量结合，并在pH=8.0时结合量最高。

Robinson Cano slugged a two-run homer and Johnny Damon worked a bases-loaded walk to open scoring in the second inning, and the Yankees added six more runs in the fourth with the benefit of two passed balls and a wild pitch.

洋基在2局下靠著 Robinson Cano 的2分全垒打和大门在满垒时选球眼的启动下打下3分。洋基之后又在第4局靠著2次捕役和1次暴投打下6分。

While many in Yankeeland were hoping to land a "true"# 1 in Santana earlier this winter, Andy Pettitte dismissed the idea that Wang was anything but an ace, calling him "a stud."

当很多洋基球员与球迷在早先冬季会议时希望洋基可以交易到真正的第一号先发投手桑塔那时，派提特不认同王建民不是王牌投手的这个想法，认为王建民是一个一流的选手。

This process is the result of the imbalance between matrix metalloproteinases zymogen activations and interaction of the active forms with specific tissue inhibitors of metalloproteinases.

本实验以大鼠为模型旨在研究急性胰腺炎中基质金属蛋白酶-2(MMP-2)与基质金属蛋白酶特异组织抑制物-2(TIMP-2)在胰腺组织中的表达，探讨其与急性胰腺炎时器官损伤程度的相关性。
