Each medicine used in the study totally has obivious effect on lens sodium-pump. Either on the molecular and cellular level or on the histological and organic level , they all have their distinctive demonstration. 1.Ouabain、Digoxine、DMSO decrease the expression of αsubunit of sodium pump on mRNA level , the cell morphology and ultramicroscopic structure demonstrated destructive effect,it indicates the cause of cataract of the medicines.2.D-thyroxine、Amphotericin B、Vitamin E increase the expression of αsubunit of sodium pump on mRNA level ,from the demonstration of the cell morphology and ultramicroscopic structure ,it indicates the medicines have protective or anti-distructive effect on lens.3.The medicines have isoform-specific action on lens sodium-pump,it indicates exploitting isoform-specific medicine has a promising clinical application.4. Lens sodium-pumps are inhibited probably lead to cataract, so in clinical medication, especially to the cardiovascular doctor, while he is using the sodium-pump inhibitors, he should pay more attention to adjust the dosage and duration of the drug therapy. 5. To creat the animal model of cataract through inhibiting lens sodium-pump, whether it can be a kind of classical method or not, it is worthy of further research.

本研究所选用的药物对晶状体钠泵均有明显的影响作用，在分子水平、细胞水平、组织器官水平均有特异的表现：1、哇巴因、地高辛、二甲基亚砜三种药物可降低晶状体钠泵α亚单位在 mRNA水平的表达，在细胞形态和超微结构上表现为损伤效应，提示了其潜在的导致白内障的可能。2、D甲状腺素、两性霉素B、维生素 E三种药物可升高晶状体钠泵α亚单位在 mRNA水平的表达，从细胞形态和超微结构上的表现，提示了其对晶状体有保护作用或抗损伤效应。3、药物作用于晶状体钠泵具有重整异构特异性，提示了开发出特异的具有重整异构作用的药物是极有临床应用前景的。4晶状体钠泵抑制后可能导致白内障的发生，故临床用药，尤其是心内科医生在使用这些钠泵抑制剂时应注意调整用药剂量及药物疗程。5 通过抑制晶状体钠泵来制作白内障动物模型能否成为一种经典的制作方法，还有待于进一步研究。

Essentially all phenomena in chemistry find explanations in the quantum atom, while chemistry and physics undergird molecular biology, which, since the discovery of DNA in the 1950s, dominates modern biology.

从本质上讲所有的化学现象都可以在量子原子中找到答案。而自二十世纪五十年代发现DNA以来一直占据现代生物学主导地位的分子生物学，在背后支撑它的是化学和物理学。

Results show that the unfolding of TIM is highly cooperative and no folding intermediate was detected in the experimental conditions used. The thermodynamic parameters of TIM during guanidine denaturation were calculated according to a two-state unimolecular unfolding model.

结果表明，用不同测量方法得到TIM的变性过程均高度协同，没有观察到折叠中间态，应用单分子二态去折叠模型计算了TIM去折叠的热力学参数。

The reaction takes place as soon as 3a is dissolved in solution. With the presence of a tethering terminal vinyl group bound to the vinylidene ligand, the [2+2] cycloaddition of two C=C double bonds readily occurred.

当有一乙烯基键结在丙二烯基上，分子内的两个碳碳双键会马上发生[2+2]的环化加成反应。

The presence of a gem-diphenylmethylene moiety at the vinylidene ligand with the appropriate terminal vinyl or alkynyl group along with the proper steric environment implements such a novel reactivity in the ruthenium vinylidene complexes.

因此推测丙二烯基与末端的不饱和键确实可以进行一些分子内的反应，但是gem-diphenylmethylene 官能基需位於适当的立体位置方可进行。

Effect of relative molecular mass on shear stability of the polymer solution was investigated by means of ultrasonic instrument and rotary viscosimeter.

His associates insisted Salah has had to be assigned round-the-clock bodyguards due to threats on his life from extreme right-wing Jewish elements in the wake of the Mercaz Harav yeshiva shooting massacre.

他的同夥坚持萨拉赫已被指派二十四小时的保镖，因为威胁他的生命，由极端右翼的犹太分子在经历了mercaz harav神学院开枪屠杀。

Started from D-tyrosine, we obtained the tetramic acid 96 using Jouin reaction. The assembly of the second fragment 109 was stared from 1,4-butandiol,using asymmetric alkylation reaction developed by Oppolzer as a key step. Coupling of the tetramic acid 96 with 109 provided the key intermediate 110 according to Yoshii\'s procedure. After remove protective group and Sharpless epoxidation, we obtained the key intermediate 113. Its macrocyclization to form the final product is in progress.

本论文的第二章主要对Macrocidin A开展了合成工作，我们从D构型的酪氨酸出发，经过官能团转换；利用Jouin反应生成Tetramic acid 96，另外一个片断从1，4-丁二醇开始经过多步反应生成碘化物104，利用Oppolzer发展的手性樟脑磺酰胺为辅基参与的不对称烷基化反应，引入手性甲基，生成关键中间体109，接着通过Yoshii发展的方法连接96和109生成110，经过Sharpless不对称环氧化反应建立环氧化合物，然后脱去保护基得到关环前体113，分子内的Mitsunobu反应进行关大环反应正在进行之中。

It can grow all right in high salt Since twenty century , molecular biology and bio-technology have a large development , agriculture and physic have been speedily development too ,especially after the plan of human genome was successfully implemented ,more people engaged in bio-technology industry .but the area of the bio-technology study was very extensive , Ocean Rhodotorulas have been studied by people at beginning, on the end of 1980s , Ocean Rhodotorulas separation from sea and Japan was the first succeed in cultivation by zymolysis , the Ocean Rhodotorula of cultivation was used for a good nutrimental to feed for fish and shrimp.

二十世纪以来，分子生物学与生物技术得到了迅猛发展，在农业和医药业都得到了飞速发展，尤其是人类基因组计划的成功实施，使人们更多的从事着生物技术行业，但是生物技术研究的范围很广，所以对于海洋红酵母的研究还处于刚刚起步阶段，上世纪80年代日本最早分离到海洋红酵母，然后发酵培养，用做鱼虾的营养饲料。
