METHODSThe compounds were prepared by using 2ethylpyridine, through the Whol Ziegler reaction, the Williamson reaction and aminolysis. The effects for ability of memory in mice were measured by swimming maze test.

方法］以2乙基吡啶为原料，经WholZiegler反应、Williamson反应及氨解反应得到2［1（2吡啶）乙氧基］乙酰4取代哌嗪，采用水迷宫法观察所合成的化合物对小鼠记忆力的影响。

Methods Compound 3 was got via the formation of the amide from 2-chloro-3-amino-4-methyl pyridine and 2-chloronicotinoyl chloride, and then nevirapine was acquired by the aminolysis of 3 with cyclopropylamine in an autoclave, followed by the intramolecular nucleophilic substitution.

以2-氯－3-氨基－4-甲基吡啶为原料，依次与2-氯烟酰氯缩合成化合物3、再与环丙胺高压氨解、最后发生分子内亲核取代反应，成功合成了奈韦拉平。

Reported that approximately 15% of patients who were treated with intravenous N-acetylcysteine had an anaphylactoid reaction within 2 hours after the initial infusion and that increasing the infusion time from 15 to 60 minutes did not alter the rate of adverse events.

Kerr等人报道大约15%的静脉注射N-乙酰半胱氨酸的病人在首次注射后2小时内出现过敏样反应，增加注入时间在15-60分钟内并不会改变副反应的发生率。

To the most suitable nitrogen source for the growth of black spot disease of Araliaceae was the complete protein peptone which was stronger than comparison, glutanic acid, asparagine,alanin, potassium nitrate, nitrate of soda, ammonium sulfate, ammonia water, ammonium chloride.

对刺五加黑斑病菌最适合生长的氮源为完全蛋白胨强于对照，强于谷氨酸，强于天门冬酰胺，强于丙氨酸，强于硝酸钾，强于硝酸钠，强于硫酸铵，强于氨水，强于氯化铵。

The results showed that precursor feeding (phenylanine, sodium acetate and benzamide) and mixed sugar as production medium resulted in significant increase of taxol production not only in the one-liquid-phase cultures of Taxus chinensis var. mairei but also in the two-liquid-phase cultures. And the integrated function of precursor feeding and mixed sugar in the two-liquid-phase cultures gave more significant increase of taxol production significant increase of taxol production, which was four times more than that of the control (the one-liquid-phase culture without precursors and mixed sugar).

结果表明前体饲喂（苯丙氨酸，醋酸钠和苯甲酰胺）和蔗糖与麦芽糖配伍作为生产培养基糖源不仅对红豆杉细胞悬浮培养，而且对其两液相培养的紫杉醇产量提高均有明显的促进作用，与对照组相比，在南方红豆杉细胞两液相培养中，采用前体饲喂和蔗糖与麦芽糖配伍作为生产培养基糖源，紫杉醇产量提高4倍多。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
