Results showed that TDI induced toxic action on spermatogenic cell,while the chondriosome was its target within the length and concentrations.

结果表明：在本实验染毒时间和染毒剂量范围内，TD I对雄性的生殖毒性主要表现为对各级生精细胞均有一定的毒性作用，作用的靶点是细胞内的线粒体；TD I通过影响各种酶的活性，干扰了睾丸组织的有氧代谢和无氧供能，抑制了细胞对能量的利用，损伤了各级生精细胞，导致生精上皮不可逆的损害，从而造成了其对雄性生殖系统的损伤；TD I对雄性生殖细胞的核酸代谢以及DNA合成有一定影响。

Chalcone synthase (CHS, EC 2. 3.1. 74), is the first key enzyme in the biosynthesis of plant flavonoids, and the key enzyme of plant secondary metabolism. It has great influence on plant physiological function.

查尔酮合成酶(chalcone synthase，CHS，EC 2.3.1.74)，是植物类黄酮物质合成途径中的第一个酶，也是植物次生代谢途径中的关键酶之一，对植物具有非常重要的生理意义。

In the third part of this dissertation, based on the leading compound ACPD, we design and asymmetric syhthesized two analogues: 56 and 57 by using Seebach's self- regeneration strategy to synthesize α,α-disubstituted amino acid as the key step.

论文的第二部分，我们利用我们所开发的合成α，α双取代氨基酸的方法，以对甲基苯甲醛为原料，经过分子内付克烷基化、氧化银氧化和氢化等16步反应，完成了代谢型谷氨酸受体拮抗剂-AIDA的不对称合成。

Till now, Studies on Sorangium have mainly been carried out on its intriguing, novel and diverse bioactive metabolites and the genes for synthesis of these metabolites. However, to our knowledge no studies on the cellulolytic activity, the unique and basic property of Sorangium among myxobacteria have been reported yet.

目前国内外关于堆囊菌的研究大都仅仅局限于新颖、功能不同的活性代谢产物的筛选和鉴定以及代谢产物合成功能基因寻找和改造方面，而对于堆囊菌能降解纤维素大分子底物这一有别于其他粘细菌的自身独特的、最基本的特性，目前尚未见到相关的研究报道。

The obtained terephthalaldhydic acid semicarbazone has such advantages as simple process and high purity (above 99% after post treatment), and can be used as standard in enzymoimmunoassay of semicarbazide.

本发明成功合成了呋喃西林代谢物氨基脲的衍生物氨基脲缩对醛基苯甲酸，合成步骤简洁，经过后处理，纯度高达99％以上，完全可以用作标准品，为以后人们对氨基脲的酶联免疫检测研究提供了方便的途径，可以满足国内对其研究的需要。

The quality of purified 2-KGA from its fermentation products was up to industrial standard. In addition, several hexoses, such as D-glucose and D-sorbitol can be utilized to synthesize 2-KGA by this newly-mixed culture. The growth and anabolism of the B529-V6 were studied in 4M〓 and 300M〓 fermentor respectively. The results showed that its growth and anabolism were affected by carbon sources, ratio of D-glucose and L-sorbose, nitrogen sources, growth factors, inoculum quality and culture condition including the initial pH value, temperature and ventilation.

新菌系B529-V6表现出了较强的高浓度L-山梨糖耐受能力、较高的底物代谢速率和较高的2-KGA转化能力，在8％山梨糖浓度的发酵培养基中培养48h，糖酸转化率较对照菌系提高了5.94％；山梨糖浓度提高至10％，其生长代谢受影响程度较小，且能不同程度地利用葡萄糖和山梨醇为底物，合成维生素C前体-2-酮基-L-古龙酸（2-KGA），其发酵产物2-KGA经反相高效液相色谱分析其质量符合工业化生产要求。

The expression of phosphorylase gene in stigma and style may beinvolved in regulating glucose metabolism and glucoprotein synthesis during pollengermination and pollen tube growth.

磷酸化酶基因在柱头和花柱中的活跃表达可能与花粉萌发和花粉管生长过程中的葡萄糖代谢和糖蛋白合成有关；磷酸化酶可能参与雌蕊及颖果发育过程中过渡性淀粉和储藏性淀粉的合成、分解和转运。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。
