9、学和植物学相比；微 生物学研究还只是刚刚开始。 2. In ancient times, the existence of microbes was hypothesized and they might be the responsible agent of diseases, which was pure speculation(推断) as there was no microscope at the time. 在古代, 人们认为有微生物存在而且微生物可能是传染病的致病原；但当时 没有显微镜；所以这一切纯属猜测。 3. The first one who suggested taxon

When a patient, particularly the elderly is prescribed frequently to take more than one thera

16、peutic agent, drug interactions resulting in toxicity will occur. 所有医生都应该负起责任解决药品滥用所引起的各种社会问题。药物用得恰当；将是人 类的一大福音；用得不当；则可能毁了人类。病人，特别是老年病人(经常性使用一种 以上治疗药物的话；往往会发生产生毒性药物的相互作用。 4. At one time, it was essential for the physician to have broad botanical knowledge, because they had to possess the ability and

17、 skill to select proper plants from which to prepare his own crude medicinal preparations. 以前；医师必须具备很广泛的植物学知识；因为他要懂得挑选适当的植物的能力和技巧；2/7页 并将它们制备成简单的药物制剂。 5. The study of biochemical and physiological effects of drugs and their mechanisms of action is termed as pharmacodynamics, whose uniqueness lies ma

18、inly in that its attention is focused on the characteristics of the drug. As a broader science, it borrows freely from both the theories and experimental techniques of the drug. As a broader science, it borrows freely from both the theories and experimental techniques of physiology, bio chemistry, i

19、mmunology, and pathology. 对药物的生化生理作用及其活性机制的研究叫做药效学；该学科的独到之处主要在于其 关注的要点是药物的特征。药效学作为一门边缘学科；大量借鉴了生理学、生物化学、 免疫学、病理学等学科的理论和实验技术。Unit 5 1. To fight against disease, the immune system generates proteins known as antibodies that bind to invading organisms. But the real case is that the immune system is not

20、to develop a specialized antibody each time it is faced with a new pathogen. In fact, the immune system select the most effective one by mass screening of its antibody repertoire, thus identifying the ones that work best. 为了对抗疾病；免疫系统生成了被称为抗体的蛋白质；它们附着于入侵细菌。但实际情 况是免疫系统并不能在每次面对一个新的病原体时都制造出一种特殊的抗体：实际上；

A parallel synthesis and a split-and-mix synthesis are different with that in a parallel synthesis, all the products are assembled sep

23、arately in their own reaction containers, while in a split-and-mix synthesis, the related compounds are mixed up in the same reaction vessel, which reduces the number of containers required. 平行合成和分裂混合合成的不同在于, 在平行合成中每个化合物都留在自己的反应器 中；而在分裂混合合成中；相关化合物都混合在同一容器中；这种方法极大地减少了 所需容器的数量。 5. At the end of a spli

24、t-and-mix synthesis, all the molecules attached to a single bead are found to be of the same structure. Chemists pull out from the mixture the beads that bear biologically active molecules and then, use sensitive detection techniques to determine the molecular makeup of the compound attached. 在分裂混合合

25、成过程结束时；可以发现所有附着于一个小珠上的分子结构都一样。化 学家们从混合物中分离出具有生物活性分子的小珠, 然后利用灵敏的探测技术来确定附 着的化合物的分子结构。Units 6 1.

29、s been shown that they are neither truly random nor haphazard, but that sampling occurs without preconceived selection of species. 尽管许多产生大量用于高通量筛选的样品的采样程序已经具有随机的特征；但是已有结果 表明他们并不是随机的；也不是任意的；除非采样是在没有先入为主的种类选择下进行的。 5. Three main research approaches are used in drug discovery and development processes:

30、(1) bioactivity or mechanism of action-directed isolation and characterization of active compounds, (2) rational drug design-based modification and analog synthesis, and (3) mechanism of action studies. 在药物发现和开发程序中应用的三种主要思路是，生物活性或作用机制为导向的分离及 活性化合物的鉴定；基于修饰或类似物合成的合理药物设计；作用机制研究。Unit 7 1. Absorption is

31、the process of a drug entering systemic circulation from its site of administration. Except direct injection into the blood vessels, other routes of administration involve the transport of cell membrane. 吸收是药物自用药部位进入血液循环的过程。除直接注入血管者外；一般的 给药方法都要经过细胞膜的转运。 2. Drug absorption, especially those orally ad

32、ministered drugs, depends on many factors, such as the intrinsic characteristics of the drug, dosage form, food, patient age and the like. 很多因素都可以影响药物的吸收,特别是口服药物的吸收；如药物本身的性 质；剂型；食物；患者年龄等。 3.

Analytical chemistry

35、aims to resolve two questions: what it is and how much it is, that is qualitative analysis and quantitative analysis. Qualitative analysis is to identify the elements,4/7页 ions and compounds contained in a sample while quantitative analysis is to determine the exact quantity. 分析化学的核心任务在于解决两个问题，一个是有什

36、么：另一个是有多少；也就是定性 分析和定量分析。定性分析是指鉴别所含的物质而定量分析是测定物质的准确含量。 2. Analytical chemistry has expanded beyond the bounds of just chemistry, and many have advocated using the name analytical science to describe the field. Even this term falls short of recognition of the role of instrumentation development and ap

37、plications. One suggestion is that we use the term analytical science and technology. 分析化学的发展已经超出了化学的边界；因此有人提议用分析科学来描述这个领域。但 是；该名词忽视了仪器发展和应用的作用；有人建议使用“分析科学和技术”这一名词。 3.

38、h arise constantly in our society. They adopt proven methodologies to new kinds of materials or to answer new questions about their composition and their reactivity mechanisms. 分析化学家致力于提高已有技术的可靠性以更好的满足社会中频繁出现的化学检测的 需求。他们将已证实的方法学应用于新型材料；或回答关于其组成及反应机理的新问题。 4. Qualitative tests may be performed by sele

39、ctive chemical reactions or with the use of instrumentation. For example, the formation of a white precipitate when adding a solution of silver nitrate to a dissolved sample indicates the presence of chloride. Infrared spectra will give “fingerprints” of organic compounds of their functional groups.

40、 定性鉴别可能通过选择性的化学反应或者仪器分析来完成。例如当把硝酸银溶液滴加到 一份溶解样品中；生成白色沉淀就说明了样品中存在氯离子。而红外光谱可以给出有机 化合物或官能团的“指纹” 5. The first phase in the testing of banned substances is called fast-screening phase, in which qualitative analysis such as GC or LC is adopted to test suspicious samples. In the second phase, GC-MS is emplo

41、yed for further testing of those suspicious samples. Finally, spectrophotometry or GC is applied for accurate quantification. 违禁药物检查的第一阶段称作快速筛选阶段；通常采用气相色谱或液相色谱等定性分析 方法检查出可疑样本：第二阶段使用气质联用对可疑样本进一步检测：最后；应用分光 光度法或气相色谱进行准确定量。Unit 9 1.

Apart from the intravenous route of d

44、rug administration, where a drug is introduced directly into the blood circulation, all other routes of administering systemically acting drugs involve the absorption of drug from the place of administration into the blood. 除了静脉注射这一给药途径可以直接进入血液循环外；所有其他全身性作用的药 物的给药途径都涉及药物从给药地点吸收进入血液的过程。 4. Biopharmac

45、euticals are pharmaceutical products consisting of (glyco) proteins, and they have a number of characteristics that set them aside from low molecular weight drugs. 生物药剂是含有，糖(蛋白的药物制剂；它们具有许多与小分子量药物不同的特性。 5. In safety testing and clinical test programs of biopharmaceuticals, questions have to be addressed regarding species specific responses, selection of dosing schedules and route of administration, and the possible occurrence of immunogenicity. 在生物制剂安全性试验和临床试验计划中；必须将重点放在种属特异性应答、给 药途径和给药方案的选择以及可能发生的免疫原性上。Unit 11 1.
