Introduction to PhysiologyIntroductionPhysiology is the study of the functions of living matter. It is concerned with how an organism performs its varied activities: how it feeds, how it moves, how it adapts to changing circumstances, how it spawns new generations. The subject is vast and embraces the whole of life. The success of physiology in explaining how organisms perform their daily tasks is based on the notion that they are intricate and exquisite machines whose operation is governed by the laws of physics and chemistry.Although some processes are similar across the whole spectrum of biology—the replication of the genetic code for or example—many are specific to particular groups of organisms. For this reason it is necessary to divide the subject into various parts such as bacterial physiology, plant physiology, and animal physiology.To study how an animal works it is first necessary to know how it is built. A full appreciation of the physiology of an organism must therefore be based on a sound knowledge of its anatomy. Experiments can then be carried out to establish how particular parts perform their functions. Although there have been many important physiological investigations on human volunteers, the need for precise control over the experimental conditions has meant that much of our present physiological knowledge has been derived from studies on other animals such as frogs, rabbits, cats, and dogs. When it is clear that a specific physiological process has a common basis in a wide variety of animal species, it is reasonable to assume that the same principles will apply to humans. The knowledge gained from this approach has given us a great insight into human physiology and endowed us with a solid foundation for the effective treatment of many diseases.The building blocks of the body are the cells, which are grouped together to form tissues. The principal types of tissue are epithelial, connective, nervous, and muscular, each with its own characteristics. Many connective tissues have relatively few cells but have an extensive extracellular matrix. In contrast, smooth muscle consists of densely packed layers of muscle cells linked together via specific cell junctions. Organs such as the brain, the heart, the lungs, the intestines, and the liver are formed by the aggregation of different kinds of tissues. The organs are themselves parts of distinct physiological systems. The heart and blood vessels form the cardiovascular system; the lungs, trachea, and bronchi together with the chest wall and diaphragm form the respiratory system; the skeleton and skeletal muscles form the musculoskeletal system; the brain, spinal cord, autonomic nerves and ganglia, and peripheral somatic nerves form the nervous system, and so on.Cells differ widely in form and function but they all have certain common characteristics. Firstly, they are bounded by a limiting membrane, the plasma membrane. Secondly, they have the ability to break down large molecules to smaller ones to liberate energy for their activities.生理学简介介绍生理学是研究生物体功能的科学。
2012药学英语翻译
Unit 1 Green pharmacy-herbal medicine1) Plant kingdom once was mere pharmacy of the human race, but now when you get into the modern pharmacy, plant-derived drugs have been hardly found.2) Although today the number of plant-based drugs has been decreased, the effective chemicals in many tables, capsule and bottle-contained drugs are originated from plant kingdom.3) Among chemical substances contained in plants, some must be toxic, but some must be drugs available to us.4) During the millions of years since man came to the earth, he has been doing experiments on a variety of plants about him.5) There exist mistrust, suspicion and hostility between the orthodox medicine and herbal practitioners for many years, which are threatening the possibility of establishing good working relationship.6) When we think of the effectiveness of quinine, the great contributions made by herbal medicine to medical science are quite evident.7) However, in the past few decades, the number of newly-introduced drugs has obviously decreased.8) The medical legacy of our motherland is an inexhaustible new-drug treasure, which remains us to tap with new methods.9) If pharmacological method had not been introduced to the study of vinca rosea, the discovery of vincaleukoblastine would have been postponed by many years.10) Western medicine hardly believes that someone who knows nothing of a disease mechanism could be capable of curing it.Unit 2 How does human body fight disease?People tend to believe that antibiotics were invented by human being, but in fact, they are purely natural products. Since Alexander Fleming, a British biologist discovered anti-microbial substance released by the Penicillium fungi in 1928, it has been learned that this substance can produce powerful antibiotic effect. In fact, antibiotics, are exactly manufactured by organisms, namely, bacteria and fungi, which people aim to destroy. After Fleming’s discovery of penicillin, Selma Walksman in 1943 isolated Streptomycin from a soil bacterium, Streptomycus griseus. Scientists have not made it clear completely why organisms can produce antibiotics. This question has become the topic for discussion.Why antibiotics are useful in medicine is that they can not only kill microbes, but also not kill the body cells as they do to the microbes, body cells are entirely different from those of bacteria cells, so that they can avoid being destroyed at the same time. Thus, antibiotics are called “magic bullet”because they may be particularly used to aim at certain microbes. This feature of antibiotics also makes them essentially different from anti-microbial agents: the latter tends to have poison to a majority of cells, whether the cells of bacteria or the body cells.Unit 3 Drug dependenceStudies indicate that drug dependencies both a health problem and a social concern. The drug dependence affects not only individual’s health but also the public health at the same time. The drug use has obviously and severely negative effects on the human brain and physical health. But drug abuse and addiction have huge and potential threat, because whether the drug is used directlyor indirectly has become the main transmitting ways for many severe communicable diseases, AIDS, hepatitis and pulmonary tuberculosis in particular, plus violent behaviors, etc. The drug addiction is such a complicated and widely health-associated problem that we must duty-boundly put the measures about the public health, extensively-launched education, prevention, treatment and scientific research into our total strategy. Science is offering the foundation to the exploration of public health, which keeps the opposite attitude to the extensively-accepted point of view. It thinks that the drug dependents are made to lose all abilities by drugs, so they cannot rectify their own behaviors. It also offers the suggestions of the foundation for revising the total strategy, so as to reduce the negative effects produced by injection of drugs on the individual and society.Unit 4 The scope of pharmacology1) The science that drugs act on the human body is known as pharmacology, while the scientists who studies this science is called pharmacologist.2) Pharmacology is not a science which can be studied alone, but one that is closely related to other sciences.3) Pharmacologist should not only learn the normal reaction process, but also know how the functions of the human body are affected by diseases.4) If the drug is properly used, it will be a boon to the human race, if not, it will destroy the human race.5) In the first half of the 20th century, the fantastic development has been achieved in the pharmacological field.6) The human race makes constant efforts not only for increasing life expectancy, but also for more healthy life.7) If a patient, the old in particular, constantly uses more than one therapeutic agent, the correlation of the drugs causing toxin tends to occur.8) The clinician is interested primarily in the drugs that are useful in the prevention, diagnosis, and treatment of human disease.9) As most of the natural drugs are now highly purified and differ little from synthetic chemical drugs, the interests of the clinicians in pharmacognosy are correspondingly limited.10) Pharmacodynamics, as a border science, borrows greatly from both the subject matter and the experimental techniques of physiology, biochemistry, microbiology, immunology, genetics, pathology and so on.Unit 5 Combinatorial chemistry and new drugs1) 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 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.2) In a process called combinatorial chemistry, chemicals generate a large number of related compounds and then screen the collection for the ones that could have medicinal value.3) In a parallel synthesis, chemists often use a so-called microtiter plate to assemble all the products separately in their own reaction vessels.4) A parallel synthesis and a split-and-mix synthesis are different with that in a parallel synthesis, all the products are assembled separately in their own reaction containers, while in a split-and-mixsynthesis, the related compound are mixed up in the same reaction vessel, which reduces the number of containers required.5) At the end of a split-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.Unit 6 Drug discovery and natural products1) Plant natural products have had, and continue to have, an important role as medicinal and pharmaceutical agents, not only as purified isolates and extractives, but also as lead compounds for synthetic optimization.2) Plant secondary metabolites also show promise for cancer chemoprevention, which has been defined as “the use of non-cytotoxic nutrients or pharmacological agents to enhance intrinsic physiological mechanisms that protect the organism against mutant clones of malignant cells”.3) Nevertheless, the vast majority of the world’s quarter of a million plant species has not been evaluated in pharmaceutical screens, and the small percentage that has been tested has generally been screened for activity against only a few therapeutic targets.4) Although many sampling programs designed to generate large numbers of samples for high-throughput screening programs have been characterized as random, it has been shown that they are neither truly random nor haphazard, but that sampling occurs without preconceived selection of species.5) Three main research approaches are used in drug discovery and development processes：（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.Unit 7 New drugs and drug delivery systems1) Every drug has its innate pharmacological characteristics. With the right dosage, frequency of administration and route of administration, most patients can get the expected pharmacological eficacy.2) But to different patients, there may be certain ,or even very obvious differences. Patients’physique, quality of drug, microorganisms and environmental factors can all affect drug fuctioning. They can enhance or decrease drug efficacy.3) The main factors that produce individual differences are the differences in drug absorption, distribution, biotransformation and elimination.4) In order to achieve the goal of maximum efficacy and minimum side effect for every patient, it is far from enough just to select drugs according to their pharmaceutical functioning.5) Other factors that influence the efficacy of different drugs must be taken into account, and appropriate therapies should be made according to the particular conditions of different patients. These therapies must be adjusted in time in the course of treatment to conform to patients’changed conditions until they recover.Unit 8 What analytical chemists do ?1) Analytical chemistry aims to resolve two questions:what it is and how much it is, that isqualitative analysis and quantitative analysis. Qualitative analysis is to identify the elements, ions and compounds contained in a sample while quantitative analysis is to determine the exact quantity.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 application. One suggestion is that we use the term analytical science and technology.3) Analytical chemists work to improve the reliability of existing techniques to meet the demands for better chemical measurements which 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.4) Qualitative tests may be performed by selective 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 indicateds the presence of chloride. Infrared spectra will give “fingerprints” of organic compounds or their functional groups.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 employed for further testing of those suspicious samples. Finally, spectrophotometry or GC is applied for accurate quantification.Unit 9 Nonclinical development of biopharmaceuticals1) The development of a new therapeutic agent involves a multidisciplinary group in many years of work, and with the development of genetic engineering and the production of monoclonal antibodies, it is likely that even more agents should be produced.2) The activity of biopharmaceuticals depends on their complicated conformation based on secondary, tertiary and quaternary structures. These structures cannot be fully defined with our present set of analytical techniques and approaches for potency testing.3) Apart from the intravenous route of drug administration, where a drug is introduced directly into the blood circulation, all other routesof adminstering systemically acting drugs involve the absoption of drug from the place of adminstration into the blood.4) Biopharmaceuticals are pharmaceutical products consisting of (glyco)proteins, and they have a number of characteristics that set them aside from low molecular weight drugs.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.Unit 10 The package insert and prescription1) The information the package insert contains is derived from data supplied by investigators and submitted by pharmaceuticalfirm to the FDA, including the chemical structure of the drug, a summary of its pharmacological and toxicological action, its clinical indications and contraindications, precautions, reported adverse reactions, dosage recommendations, and available dosage forms.2) The physician may exercise his professional judgment in the use of any drug. However, if he deviates from the instructions in the package insert and adverse reactions occur, he must beprepared to defend his position in court if there is a malpractice suit.3) If a severe reaction occurred and litigation followed, how would a court react if a physician admitted to the use of this drug for the treatment of some diseases in view of the prohibitions in the package insert? Would the published clinical study, plus the physician’s judgment in prescribing the drug, suffice?4) The FDA cannot requirea pharmaceutical firm to include a new use for the drug product in the insert even if it has been clinically tested and found useful for a given problem. But, if a new use for a drug is not yet included in the package insert, the manufacturer cannot advertise his product for that particular use.5) Today, the FDA’s regulatory scope and authority include ensuring the safety and purity of foods, drugs, medical devices, nutritional supplements, vaccines and cosmetics. Of particular concern to the anesthesiologist is the timely access to drug evaluation, pharmacologic, and medical device data. With the dramatic upsurge in the number of new prescription drugs and over-the-counter supplements, the need for up-to-date drug information has never been more crucial.Unit 11 Development od new drugs(1)1) Formerly, drugs were extracted from natural plant and animal sources. Therapeutic use was empirical and based on traditional experiences.2) The strategies of the drug research include occasional discoveries, random molecular combination, and a planned research of synthesis of a certain specific chemical element.3) Although this is a ideal method of the development of new drugs, it is expensive and there is no guarantee of success.4) When a drug is used by millions of people, it is sure to develop unhealthy response, though this harm is not too big to particular people.5) Most drugs have a maximum safe dose, if the dose exceeds the limited extent, it will produce toxic side effects.6) Penicillin, one of the most powerful bacterium-killers in the world, was incidentally discovered by Fleming.7) The pharmacological experiment of a new drug will determine whether the drug has the desired medicinal functions in model systems.8) The addition of awareness of the biochemical mechanism will make the development of new drugs more rational.9) Extensive formal toxicological tests are required before new drugs can be used on patients.10) Now chemists and biologists attach importance to research fields of molecular biology, biochemical pharmacology, and so on.Unit 12 Development od new drugs(2)1) The rationale for the development of new drugs should be to provide better drugs, better in the sense of being either more effective, safer or cheaper.2) The promotion representative of the pharmaceutical manufacturer has been trained to promote a certain new product.3) The clinical evaluation of new drugs should be made after the study on animals proves effective.4) A new drug evaluation in man can be considered in four phases, each of which should be doneunder the strict supervision.5) Dose-ranging study should only be performed in volunteers who are informed about the implications of the tests, and who give their consent freely.6) As dose-ranging study may have a certain dangerous nature, it can only be carried out under medical supervision.7) A large scale of clinical trials in phase 3 will establish the new drug’s profile of action and frequency of adverse effects.8) The large cost of the drug development is borne by the pharmaceutical industry, which justifiably expects to recoupe it when the product is finally marketed.9) Information about new drugs published in well-established journals is more believable than the introductions by the representatives living on promotion.10) Heavy investment used in promotion of new drugs has not only led to the use of undistinguished new drugs but also raised the cost of the drugs.Unit 13 The impact of pharmaceutical care on drug therapy1) The focus of pharmaceutical care is to optimize drug therapy, minimize drug-related problems, and improve self-management for the purpose of achieving the optimal outcome to improve the patients’ quality of life.2) Diabetes mellitus is a group of metabolic diseases characterized by chronic hyperglycemia resulting from defects in insulin secretion, insulin action, or both. Ultimately, it is likely to lead to complications.3) The Pharmaceutical Care process for the patients in the Intervention Group consists of three sections. One of them is provided at hospital, then seamless care at the time of discharge from hospital and the last in the ambulatory setting.4) Pharmaceutical care has a clear benefit and positive impact on patient’s HRQoL, which is feasible in the hospital and in the community setting.5) The result of the study demonsreates that patients who do not receive intensified PC have a higher chance of deteriorationg their quality of life.Unit 14 FDA’s responsibilities and activities1) Before a new drug goes to the market and is widely used, the manufacturer should get the license from the corresponding authorized government agency(Drug Safety Commiittee in Britain; Food and Drug Administration in USA;Medical Products Agency in Sweden and etc).2) The new drug probably has been taken by more than 3000 healthy volunteers or patients in controlled studies before marketed unless it is only designed for some orphan diseases in small scale trials.3) At the present stage, most of the pharmacological effects are well-known and the side effects caused by overdosages have been documented. However, the recognition of unpredicted toxic and side effects are rarely known by humans until after the extensive use of the drugs.4) Continuous use of beta receptor blocking drug practolol for a comparative period of time may produce a syndrome of ocular mucosa and dermis, which had been discovered after several years.5) In similar manner, when thalidomide was discovered to make pregnant women who had taken the medicine during their early pregnancy bear babies with limb deformity, it had been sold on market for a few years.Unit 15 Good manufacturing practices(GMP)1) GMP is probably the most widespread quality system followed across the pharmaceutical industry as a whole. GMP compliance is a requirement within the R&D environment for the manufacture and testing of clinical trial materials (both drug product and API) and for commercial manufacture and testing of these materials.2) Although the FD&C Act requires all drugs (products and APIs) to be manufactured to cGMP, the regulations 21CFR parts 210 and 211 are only mandatory for the manufacture of drug products and not APIs. It is only with the issue of ICH Q7 A that the worldwide pharmaceutical industry finally received detailed guidance for manufacture of APIs for boh commercial and R&D purposes.3) There have been distinct and fundamental differences between USA regulation and EU/UK requirements for GMP. The US required all drugs to be made to GMP requirements and performed inspections throughout the world in support of these requirements. In the UK, only drug products and biological manufacturers (not APIs, except some specified antibiotics) were inspected by the regulatory authority fot compliance to GMP.4) An API is normally prepared by chemical processes and even if purification is involved at each stage of manufacture, impurities in APIs can not be removed thoroughly. Therefore, trace impurities are allowed to be present in drug product to a limited extent.5) Harmonization with the US through a Mutual Recognition Agreement（MRA）is seen as a big saving of inspection resources to both the EU and the USA, through mutual acceptance of API facility inspection reports.。

Text B How Does FDA Approve New Drugs?Under current law, all new drugs need proof that they are effective, as well as safe, before they can be approved for marketing. But it’s important to realize that no drug is absolutely safe. There is always some risk of an adverse reaction. It’s when the benefits outweigh the risks that FDA considers a drug safe enough to approve.1.outweigh [a u tˊweɪ] vt. 在重量上超过；在重要性或价值方面超过根据现行法规，对于所有新药，只有经确认安全、有效，才会被批准上市。
但是，我们应该意识到没有所谓绝对安全的药物，认识到这一点是很重要的。
任何药物都可能有不良反应。
因此，只有认定某种药物的益处大于其风险时，FDA 才会认为某种药物足够安全，可批准其上市。
In fact, it was only 25 years ago that U.S. drug law first embraced the idea of risk vs. benefit that now the key to new drugs approval. Providing evidence of safety before marketing was first required by Federal Food, Drug and Cosmetic Act in 1938, but not until the Drug Amendments of 1962 did firms also have to show a drug’s effectiveness before marketing. Before any drug gets on the market today, FDA decides—as quickly as a thorough evaluation allows—whether the studies submitted by the drug’s sponsor(usually the manufacturer) show it to be safe and effective for its intend use.1.embrace [im'breis] vt. 包括; 包含；接受；信奉, 皈依vt. & vi.拥抱n.拥抱, 怀抱2.cosmetic [kɔz'metik]n.化妆品adj.化妆用的; 美容的；装点门面的Federal Food, Drug and Cosmetic Act联邦食品、药品和化妆法案3.Drug Amendments [ə'mendmənts] 药品法修正案4.thorough ['θʌrəu] adj.彻底的；十足的；考虑周到的5.sponsor ['spɔnsə] vt.赞助, 发起, 主办n. 申办者事实上，直到25年前美国药品管理法才刚刚引入“风险-益处评估”的概念。
药学英语课文3翻译
Foods That Fight Cancer抗癌症的食物Foods That Fight CancerDiet is now considered a major weapon(武器) against cancer. The National Cancer Institute （协会）estimates that about one-third of all cancers are linked to diet, and recent research indicated（指出）that what you eat may help to significantly reduce your risk.Cancer develops over a long time, which means that you have years-typically decades（数十年）-in which to hinder（阻碍）or promote it. Researchers are finding that what you eat may interfere（妨碍）with cancer growth at various stages. For example, certain foods can block (v.阻碍) the chemicals that initiate（开始）cancer. Antioxidants（抗氧化剂）, found in some vitamins and minerals（矿物）, can snuff（消灭）out oxygen free radicals（基础；原子团）, substances that are thought to make cells more susceptible（易受影响的）to cancer, and they can even repair some of the cellular damage that has been done. And some food-wheat bran in particular-has been shown to shrink（收缩）precancerous（癌症前期的）cells.A recent review（评论）of 17 studies from 17 nations reveals that people who eat the most fruits and vegetables have about half the cancer rates of those who eat the least. That includes cancers of the lung, colon（结肠）, breast, cervix（宫颈）, esophagus（食道）, oral cavity（口腔）, stomach, bladder（膀胱）, pancreas（胰腺）and ovary（卵巢）. In fact, some research suggests that frequent consumption（肺痨;消耗）of fruits and vegetables can cut the risk of lung cancer even in smokers. “It is almost mind-boggling（难以理解的）,” says Tim Byers, an epidemiologist （流行病学家）with the U. S. Centers for Disease Control and Prevention, “that ordinary fruits and vegetables can be so effective against such a potent（有效的）carcinogen（致癌物质）as cigarette smoke.”One of the most studied antioxidants in vegetables and fruits thought to protect against cancer is beta-carotene（B-胡萝卜素）, concentrated（聚集）in deep green, yellow and orange vegetables such as carrots, sweet potatoes and spinach（菠菜）. Fruits high in beta-carotene include apricots （杏）and cantaloupes（哈密瓜）. In test-tube（试管）studies at Harvard University, beta-carotene had a direct toxic effect on cells taken from malignant（有害的）tumors（肿瘤）. It also reduced the growth of lung-cancer cells and altered（改变）the proteins needed for tumors to grow.Research also shows that beta-carotene can change in the body to retinoid acid（视黄酸）, a substance used in clinical trials to treat certain cancers.Here are some of the foods that contain cancer-fighting chemicals.Tomatoes. One of the compounds in tomatoes that is thought to reduce the risk of cancer is lycopene（番茄红素）, the pigment（色素）that makes tomatoes red. Lycopene, an antioxidant that is also found in watermelons and apricots, quenches（结束）certain cancer- triggering oxygen free radicals.Having little lycopene in your blood is associated with a higher risk of pancreatic cancer, according in a Johns Hopkins University study. People with pancreatic cancer showed lower levels of lycopene compared with healthy individuals. Those with the least blood lycopene had over five times the risk of pancreatic cancer as healthy people with the most blood lycopene.Lycopene is present in tomato products, including sauces（酱油）, tomato paste and even ketchup（番茄酱）.Green Vegetables. A recent Italian study showed that dark-green leafy vegetables lower the risk of many cancers. Spinach, broccoli（西兰花）, kale（甘兰）and dark-green lettuces（油麦菜）are chock-full of antioxidants, including beta-carotene, folate and lutein，. A good rule ofthumb: the darker the vegetable, the more antioxidants within.Citrus（柑橘类）Fruit. “Eat oranges, grapefruits（葡萄柚）, lemons and limes as often as possible,”says toxicologist Herbert Pierson, a former project officer with the National Cancer Institute. He calls citrus fruit an all-around cancer package because it possesses every class of natural substances (carotenoids（类胡萝卜素）, flavonoids（黄铜）and others) that individually have neutralized（中立的）powerful chemical carcinogens in animals.Citrus fruit may be particularly effective in reducing the risk of pancreatic cancer. One study found that in a group of Swedes, those who ate a citrus fruit almost daily reduced the risk of pancreatic cancer by one-half to more than two-thirds, as compared with eating citrus fruit less than once a week.Cruciferous（十字花科的）Vegetables. Cruciferous vegetables, such as cabbage, cauliflower, Brussels sprouts, broccoli, kale, mustard greens and turnips, may reduce the risk of breast cancer. In fact, researchers at Eppley Institute for Research in Cancer and Allied diseases at the University of Nebraska at Omaha found that feeding animals cabbage and collard greens (also a cruciferous vegetable), along with a low-fat diet, reduced the incidence（发病率）of mammary（乳腺癌）cancers. Eat cruciferous vegetables raw（生食）or lightly cooked. Overcooking may destroy the indoles（吲哚）, compounds found in these vegetables that may protect against cancer.Cruciferous vegetables may also work to head off stomach and colon cancer. Research conducted in Utah revealed（显示）that men who ate the most cruciferous vegetables had a 70 percent lower risk of colon cancer than those who ate the least of such vegetables.Soybeans. Soybeans contain at least five compounds believed to（抑制）cancer. In fact, one of the compounds is chemically similar to the drug tamoxifen （三苯氧胺）, which is routinely used to treat estrogen-dependent（雌性激素）breast cancer and is now being tested in a large clinical trial to see if it can prevent the disease. In animal studies, soybean constituents have been found to block colon, skin and other cancers by possibly slowing the growth and division（分割）of cancer cells.Wheat Bran. Wheat bran may lower the risk of colon cancer. A double-blind（双盲）study of patients at The New York Hospital-Cornell Medical Center found that two one-ounce servings of wheat bran cereal（谷类）a day caused premalignant colon polyps（息肉）to shrink within six months. Most remarkable, say researchers, is that such a small amount of food could have such an impact within a short period of time, illustrating（图解）that dietary intervention（饮食干预）may work even after precancerous warning signs have appeared.Low-Fat Milk. While the saturated（饱和的）fat in milk seems to promote certain cancers, another substance in milk may deter（阻止）them. Researchers at Roswell Park Cancer Institute in Buffalo, N. Y., discovered, not surprisingly, that drinkers of whole milk had higher odds than non-milk-drinkers of developing cancers of the oral cavity, stomach, colon, rectum, lung, bladder, breast and cervix. But they also found that those drinking low-fat milk were less likely than non-milk-drinkers to develop cancers of the oral cavity, stomach, rectum and cervix. Why? Scientists suspect（猜想）that elements（基础）such as calcium, riboflavin, or vitamins A, C, and D (present in whole milk, too, but apparently less effective) may act as anti-cancer agents in ways not yet understood.To get the most cancer-protective compounds from your diet, strive（努力）for five or more servings of fruits and vegetables daily, advises the National Cancer Institute. One serving means one-half cup of most cooked or raw fruits or vegetables, one cup of raw leafy vegetables, onemedium（半生的）piece of fresh fruit, or six ounces of fruit juice or vegetable juice. The ideal diet is low in fat and calories, high in fiber, and it includes a variety of nutrient-rich foods such as fruits, vegetables, whole grains, beans, seeds, nuts（坚果）and, if desired, low-fat animal proteins.翻译：抗癌的食物现在饮食开始被考虑作为抵抗癌症的主要武器。

Lead CompoundsBefore any medicinal chemistry project can get underway, a lead compound is required. A lead compound will have some property considered therapeutically useful. The property sought will depend on the tests used to detect the lead compound, which in turn depends on the drug's target. The level of biological activity may not be particularly high, but that does not matter. The lead compound is not intended to be used as a clinical agent. It is the starting point from which a clinically useful compound can be developed. Similarly, it does not matter whether the lead compound is toxic or has undesirable side effects. Again, drug design aims to improve the desirable effects of the lead compound and to remove the undesirable effects.1.seek [si:k] vt. & vi.寻找; 探寻vi.企图; 试图vt.请求, 征求;2.in turn ①依次, 轮流地；②相应地；转而3.target ['tɑ:ɡit]n.

Text B How Does FDA Approve New Drugs?Under current law, all new drugs need proof that they are effective, as well as safe, before they can be approved for marketing. But it’s important to realize that no drug is absolutely safe. There is always some risk of an adverse reaction. It’s when the benefits outweigh the risks that FDA considers a drug safe enough to approve.1.outweigh [a u tˊweɪ] vt. 在重量上超过；在重要性或价值方面超过根据现行法规，对于所有新药，只有经确认安全、有效，才会被批准上市。
但是，我们应该意识到没有所谓绝对安全的药物，认识到这一点是很重要的。
任何药物都可能有不良反应。
因此，只有认定某种药物的益处大于其风险时，FDA 才会认为某种药物足够安全，可批准其上市。
In fact, it was only 25 years ago that U.S. drug law first embraced the idea of risk vs. benefit that now the key to new drugs approval. Providing evidence of safety before marketing was first required by Federal Food, Drug and Cosmetic Act in 1938, but not until the Drug Amendments of 1962 did firms also have to show a drug’s effectiveness before marketing. Before any drug gets on the market today, FDA decides—as quickly as a thorough evaluation allows—whether the studies submitted by the drug’s sponsor(usually the manufacturer) show it to be safe and effective for its intend use.1.embrace [im'breis] vt. 包括; 包含；接受；信奉, 皈依vt. & vi.拥抱n.拥抱, 怀抱2.cosmetic [kɔz'metik]n.化妆品adj.化妆用的; 美容的；装点门面的Federal Food, Drug and Cosmetic Act联邦食品、药品和化妆法案3.Drug Amendments [ə'mendmənts] 药品法修正案4.thorough ['θʌrəu] adj.彻底的；十足的；考虑周到的5.sponsor ['spɔnsə] vt.赞助, 发起, 主办n. 申办者事实上，直到25年前美国药品管理法才刚刚引入“风险-益处评估”的概念。
药学英语第四版课后翻译
药学英语第四版课后翻译Unit One1. A full appreciation of the physiology of a living organism must be based on a soundknowledge of its anatomy. Anatomy does not merely study the separation of parts, but the accurate description of the morphologies and functions of different organs.2.Our daily food intake must match requirements and any excess must be excreted for balanceto be maintained.3.The process of stabilization of the internal environment is called homeostasis and is essentialif the cells of the body are to function normally.4.Human cells have the ability to break down large molecules to smaller ones to liberatesufficient energy for their activities.5.As long as normal conditions are maintained in this internal environment, the cells of the bodycontinue to live and function properly.Unit Two1.Biochemistry asks how the thousands of different biomolecules interact with each other toconfer the remarkable properties of living organisms.2.Enzymes are catalysts that accelerate the rates of biological reactions. Each enzyme is veryspecific in its foundation and acts only in a particular metabolic reaction.3.One of the most fruitful approaches to understand biological phenomena has been to purify anindividual chemical component, such as protein, from a living organism and to characterize its chemical structure or catalytic activity.4.The chemical principles that govern the properties of biological molecules include thecovalent bonding of carbon with itself and with other elements and the functional groups that appear in common biological molecules, etc.5.The basic unit of DNA is a linear polymer of four different monomeric subunits,deoxyribonucleotides, arranged in a precise linear sequence.Unit Four1.The science of the effects on the body is called pharmacology, and the scientists who study itare pharmacologists. Pharmacology is not a science that can be studied on its own, but that closely related to other branches of science. Pharmacologists should not only understand he normal processes that take place in the body, but know how the functions of the body are affected by disease.2.For physicians and medical students, the scope of pharmacology is not so expansive as itscommon definition. The clinician is interested primarily in drugs that are useful in the prevention, diagnosis, and treatment of human disease, or in the prevention of pregnancy.3.All physicians should share the responsibility to resolve kinds of sociological problemscaused by the abuse of drugs. Properly used, drugs are great blessing to mankind; improperly used, they could destroy human race. When a patient, particular the elderly is prescribed frequently to take more than one therapeutic agent, druginteractions resulting in toxicity will occur.4.At one time, it was essential for the physician to have broad botanical knowledge, becausethey had to possess the ability and skill to select proper plants from which to prepare his owncrude medicinal preparation.5.The study of biochemical and physiological effects of drugs and their mechanisms of action istermed as pharmacodynamics, whose uniqueness lies mainly 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 physiology, biochemistry, immunology, and pathology.Unit Five1.To fight against disease, the immune system generates proteins known as antibodies that bindto invading organisms. But the real case is that the immune system is not 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.2.In a process called combinatorial chemistry, chemists generate a large number of relatedcompounds and then screen the collection for the ones that could have medicinal value.3.In a parallel synthesis, chemists often use a so-called microtiter plate to assemble all theproducts separately in their own reaction vessels.4. A parallel synthesis and a split-and-mix synthesis are different with that in a parallel synthesis,all the products are assembled separately 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 container required.5.At the end of a split-and-mix synthesis, all the molecules attached to a single bead are foundto 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.Unit Six1.Plant natural products has had, and continued to have, an important role as medicinal andpharmaceutical agents, not only as purified isolates and extractives, but also as lead compounds for synthetic optimization.2.Plant secondary metabolites also show promise for cancer chemoprevention, which has beendefined as “the use of non-cytotoxic nutrients or pharmacological agents to enhance intrinsic physiological mechanisms that protect the organism against mutant clones of malignant cells.”3.Nevertheless, the vast majority of the world’s quarter of a million plant species has not beenevaluated in pharmaceutical screens, and the small percentage that has been tested has generally been screened for activity against only a few therapeutic targets.4.Although many sampling programs designed to generate large numbers of samples forhigh-throughput screening programs have beencharacterized as random, it has been shown that they are neither truly random nor haphazard, but that sampling occurs without preconceived selection of species.5.Three main research approaches are used in drug discovery and development processes: (1)bio-activity 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.Unit Seven1.Absorption is the process of a drug entering（现在分词作后置定语）systemic circulationfrom its site of administration. Except direct injection into the blood vessels, other routs of administration involve the transport of cell membrane.2.Drug absorption, especially those orally administered drugs, depends on many factors, such asthe intrinsic characteristics of the drug, dosage form, food, patient age and the like.3.The distribution of a drug in the body is even and is in a state of dynamic equilibrium, that is,it changes constantly with the absorption and elimination of the drug.4.After a drug enters the blood, it will more or less bind to plasma protein, but this binding isloose and reversible, and is always in a state of equilibrium.5.Bioavailability is the relative quantity and rate of drugs with different dosage forms which areabsorbed and reach the systemic circulation; it is concerned with the intensity and speed of drug action.Unit Eight1.Analytical chemistry aims to resolve two questions: what it is and how much it is, that isqualitative analysis and quantitative analysis. Qualitative analysis is to identify the elements, ions and compounds contained in a sample while quantitative analysis is to determine the exact quantity.2.Analytical chemistry has expanded beyond the bounds of just chemistry, and many haveadvocated using the name analytical science to describe the field. Even this term falls short of recognition of the role of instrumentation development and application. One suggestion is that we use the term analytical science and technology.3.Analytical chemists work to improve the reliability of existing techniques to meet thedemands for better chemical measurements which arise constantly in our society. They adopt proven methodologies to new kinds materials or to answer new questions about their composition and their reactivity mechanisms.4.Qualitative test may be performed by selective chemical reaction or with the use ofinstrumentation. 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 or their functional groups.5.The first phase in the testing of banned substance is called fast-screening phase, in whichqualitative analysis such as GC or LC is adopted to test suspicious samples. In the second phase, GC-MS is employed forfurther testing of those suspicious samples. Finally, spectrophotometry or GC is adopted for accurate quantification.Unit Nine1. The development of a new therapeutic agent involves a multidisciplinary group in many years of work, and with the development of genetic engineering and the production of monoclonal antibodies, it is likely that even more agents should be produced.2. The activity of biopharmaceuticals depends on their complicated conformation based on secondary, tertiary and quaternary structures. These structures cannot be fully defined with our present set of analytical techniques and approaches for potency testing.3. Apart from the intravenous route of drug administration, where a drug is introduced directly into the blood circulation, all other routes of administering systemically acting drugs involve theabsorption of drug from the place of administration into the blood.4. Biopharmaceuticals are pharmaceutical products consisting of (glyco) proteins, and they have a number of characteristics that set them aside from low molecular weight drugs.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.Unit Eleven1) The information the package insert contains is derivedfrom data supplied by investigators and submitted by pharmaceutical firm to the FDA, including the chemical structure of the drug, a summary of its pharmacological and toxicological action, its clinical indications and contraindications, precautions, reported adverse reactions, dosage recommendations, and available dosage forms.2) The physician may exercise his professional judgment in the use of any drug. However, if he deviates from the instructions in the package insert and adverse reactions occur, he must be prepared to defend his position in court if there is a malpractice suit.3) If a severe reaction occurred and litigation followed, how would a court react if a physician admitted to the use of this drug for the treatment of some diseases in view of the prohibitions in the package insert? Would the published clinical study, plus the physician’s judgment in prescribing the drug, suffice?4) The FDA cannot require pharmaceutical firm to include a new use for the drug product in the insert even if it has been clinically tested and found useful for a given problem. But, if a new use for a drug is not yet included in the package insert, the manufacturer cannot advertise his product for that particular use.5) Toda y, the FDA’s regulatory scope and authority include ensuring the safety and purity of food s, drugs, medical devices, nutritional supplements, vaccines and cosmetics. Of particular concern to the anesthesiologist is the timely access to drug evaluation, pharmacologic, and medical device data. With the dramatic upsurge in the number of new prescription drugs and over-the-counter supplements, the need for up-to-date drug information has never been more crucial.Unit Twelve1) Formerly, drugs were extracted from natural plant and animal sources. Therapeutic use was based on traditional experiences.2) Drug development strategies involve serendipity, molecular roulette, programmed basic research with synthesis of specific chemical, etc.3) When a drug is used by millions, there are certain to be adverse reactions even though the risk to any individual is small.4) The pharmacological experiment on a new drug determines whether the drug has the desired profile in model system.5) Chemists and biologists have now attached importance to such fields of research as molecular biology and biochemical pharmacology.。

Passage 1 and 2Overview of the Digestive System-translationOverview of the Digestive SystemConsider for a moment a Big Mac. The purpose in your eating a Big Mac, oth er than simple hedonism, is to assimilate the nutrientsit represents and make them available to build, repair and maintain your own ti ssues, as well as provide energy for studying and occa-sional other pursuits.You may have asked yourself -"Exactly what nutients are present in a Big Mac that I can assimilate?" MacDon ald's comes close tofull disclosure in this regard, but what they don't tell you is that in order to take advantage of these nutrients, you have to provide themeans to carefully break them down into much smaller molecules that can be i mported into blood. Luckily, your digestive system takescare of this very complex process so efficiently that most of the time you don't ev en need to think about it.At its simplest, the digestive system it is a tube running from mouth to anus. This tube is like an assembly line, or more properly, adissembly line. Its chief goal is to break down huge macromolecules (proteins, fa ts and starch), which cannot be absorbed intact, intosmaller molecules (amino acids, fatty acids and glucose) that can be absorbed ac ross the wall ofthe tube, and into the circulatory systemfor dissemination around your body.Consider for a moment a Big Mac. The purpose in your eating a Big Mac, othe r than simple hedonism, is to assimlate the nutrients itrepresents and make them available to build, repair and maintain your own tiss ues, as well as provide energy for studying and occasio-nal other pursuits.The breakdown of foodstuffs like a Big Mac is accomplished through a combin ation of mechanical and enzymatic processes. Toaccomplish this breakdown, the digestive tube requires considerable assistance f rom accessory digestive organs such as the salivaryglands, liver and pancreas, which dump their secretions into the tube. The nam e "accessory" should not be taken to mean dispensible;indeed, without pancreatic enzymes you would starve to death in short order.In many ways, the digestive system can be thought of as a well-run factory in which a large number of complex tasks are performed.The three fundamental processes that take place are:• Secretion: Delivery of enzymes, mucus, ions and the like into the lumen, a nd hormones into blood• Absorption: Transport of water, ions and nutrients from the lumen, across the epithelium and into blood• Motility: Contractions of smooth muscle in the wall of the tube that crush, mix and propel its contentsEach part of the digestive tube performs at least some of these tasks, and diff erent regions of the tube have unique and importantspecializations.Like any well-run factory, proper function ofthe digestive system requires robust control syste ms. Control systems must facilitatecommunication among different sections of the digestive tract (i.e. control on the factory floor), and between the digestive tract and thebrain (i.e. between workers and managment). Control of digestive function is ach ieved through a combination of electrical and hormonalmessages which originate either within the digestive system's own nervous and endocrine systems, as well as from the central nervoussytem and from endocrine organs such as the adrenal gland. Different parts of t hese systems are constantly talking to one another. Thebasic messages are along the lines of "I just received an extraordinary load of fo od, so I suggest you get prepared" (stomach to largeintestine) or "For goodness sake, please slow down until I can catch up with wha t you've already given me" (small intestine to stomach).Finally, a note about differences in digestive anatomy and physiology among animals. The digestive systems of humans, dogs, mice,horses, kangaroos and great white sharks are, to a first approximation, virtually identical. If you look more carefully however, it becomesapparent that each of these species has evolved certain digestive specializations that have allowed it to adapt to a particular diet.These differences become particularly apparent when you compare a carnivo re like a cat with a herbivore like a goat or a horse.Goats and horses evolved from ancestors that subsisted on plants and adapted parts of their digestive tracts into massive fermentationvats which enabled them efficiently utilize cellulose, themajor carbohydrate of p lants.In contrast, cats evolved from animals that lived on the carcasses of other a nimals, and have digestive systems that reflect thishistory-extremely small fermentation vats and essentially no ability to utilize cellulose. Bridging the gap between carnivores and herbivores are omnivores like humans and pigs, whose digestive tracts attest to a histori cal diet that included both plants and animals.
