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.。

药学英语Unit 1Inflammatory reaction induced by local ischemic injury is one of the important pathophysiological characteristics after ischemic stroke, so anti-inflammatory therapy may be an effective strategy for acute ischemic stroke. Enlimomab, an anti-ICAM-1 murine monoclonal antibody, can inhibit the recruitment and activity of polymorphonuclear leukocytes, reduce their adhesion and decrease cerebral infarct size in experimental stroke models. However, a much larger efficacy trial including 625 acute ischemic stroke patients has shown that enlimomab was ineffective on ischemic stroke patients even with a worsening outcome. The therapeutic time window of rt-PA is within 3 hours of ischemic onset. Administration of the drug after more than 3 hours of ischemic onset has no significant therapeutic implications and may even end up with an increased hemorrhagic risk. A study using the animal ischemic model indicated that combination of anti-inflammatory therapy and rt-PA could significantly and might as well extend the therapeutic time window of thrombolysis.局部脑缺血损伤引起的炎症反应是缺血性脑卒中发生后的重要病理生理特征，因此，抗炎治疗策略可能是治疗急性缺血性脑卒中的一种有效方法。

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。

药学英语Unit 1Inflammatory reaction induced by local ischemic injury is one of the important pathophysiological characteristics after ischemic stroke, so anti-inflammatory therapy may be an effective strategy for acute ischemic stroke. Enlimomab, an anti-ICAM-1 murine monoclonal antibody, can inhibit the recruitment and activity of polymorphonuclear leukocytes, reduce their adhesion and decrease cerebral infarct size in experimental stroke models. However, a much larger efficacy trial including 625 acute ischemic stroke patients has shown that enlimomab was ineffective on ischemic stroke patients even with a worsening outcome. The therapeutic time window of rt-PA is within 3 hours of ischemic onset. Administration of the drug after more than 3 hours of ischemic onset has no significant therapeutic implications and may even end up with an increased hemorrhagic risk. A study using the animal ischemic model indicated that combination of anti-inflammatory therapy and rt-PA could significantly and might as well extend the therapeutic time window of thrombolysis.局部脑缺血损伤引起的炎症反应是缺血性脑卒中发生后的重要病理生理特征，因此，抗炎治疗策略可能是治疗急性缺血性脑卒中的一种有效方法。

药学英语课文翻译Unit1药品根据他们的产品或来源药物可以被分为三种：Ⅰ、全合成Ⅱ、天然产物和Ⅲ、由部分合成产物（半合成产物）本书的重点是关于最重要化合物Ⅰ和Ⅲ——这类药物合成。
然而，这并不意味天然产物和其他的药物就不重要。
它们可以被用作有价值的先导化合物，并且它们通常被用作起始原料或作为重要合成产物的中间体。
合成而更加经济的。
在过去的几年里发酵，即微生物工程，已经变得极其重要。
通过现代技术和基因的选择结果，导致了微生物高突变体演变的产生，发酵已经变成了对物质广泛围的选择方式。
真核细胞（酵母和霉菌）和原核细胞（单细菌细胞和放线菌）都被用作微生物。
以下为可获得的生产形式:1.细胞原料（单细胞蛋白质）2.酶3.初级的降解产物（初级酶代物）4.次级的降解产物（次级的代物）在次级代物中，必先提起的是抗生素，以下五种药代表了每年世界围价值170亿美元的药物：青霉素，头孢菌素，四环素，红霉素，氨基糖苷类。
大约有5000种抗生素已经从微生物中分离出来了，但在这些中仅有那些少于100种用于治疗使用。
然而，一定知道，那些衍生物通过部分合成被改进用于治疗。
在过去十年中，单单从β-酰胺半合成的就有五万种药物。
发酵在容积大于400m3的不锈钠发酵罐中进行，避免了微生物噬菌体的污染等等，整个过程必须在无菌条件下进行。
（倒数第五段开始）大量使用的试剂不仅仅是酸（盐酸、硫酸、硝酸、醋酸），还有无机和有机碱（氢氧化钠、氢氧化钾、碳酸钾、重碳酸钾、铵碱、三乙胺、吡啶）。
还有辅助化学物质包括活性炭和催化剂。
所有这些补充的化学物质（比如中间体）在最终产物中可能是杂志的来源。
在1969年，世界卫生组织出版了关于“药品安全质量保护”的论述。
目录2是有关“药品赔偿和安全保护质量的规定”（世界卫生组织，1969年第418号技术报告，目录2；1975年第567号目录1A）这同时变为众所周知的“药品质量管理规”或GMP规，并且这些规定在现在药品生产中也应遵守。
它们形成了联系药品生产质量认证相互组织的基本原则和用于生产设备的视察。
在相当长的一段时间美国药品权利机构，食品药品监督管理局，已出版类似于WHO规定，用于药品生产的标准，严格执行这些规定。
出口药品到美国，如那些最终产品，需要通过FDA常规检查生产设备。
如此仔细的控制应用不仅仅只对产品，还有原材料（控制起始原料）和中间体，显然的生产工艺和卫生设备及存储空间必须满足固定条件。
目前仅少数化合物，如乙酰水酸，对乙酰氨基酚和维生素是大量生产，实际大部分在多用途（多产量）的设备中生产。
特别注意避免通过使用过的设备清洁残留物与其他产品交叉污染。
所有的储存媒介和产品都需要严格区分和保管。
Unit 5 药品发展1 Introduction（介绍）药品研发是一个非常复杂的过程，需要广泛的不同功能的群体之间的协调和沟通。
它是昂贵的，特别是在临床实验的后期阶段，其中包括对数百名病人的研究。
目前估计，一种新药的开发要花费约2.3亿美元（1987美元），并且至最初上市需7-10年的临床前开发阶段（不包括监管后滞）。
药品开发是一项高风险业务：虽然利率不断上升，但在对人类进行首次研究的新的化学实体中，每十个中约只有一个将能称为产品。
候选药物的开发进展，一路上克服“障碍”，减少失败的风险。
失败的典型原因包括不可接受的毒性，缺乏有效性，或与其他竞争产品相比较没有优势。
2 Planning for development(规划发展)评估候选药物是否有可能提供有竞争力的优势，首先强调的是需要有一个目标产品或目标产品简介。
应特别注意与竞争对手的区别。
处方，医疗费用以及药物经济学变得越来越关键（本章稍后讨论）。
目标简介将确定一个候选药物将被开发，随着目标的指示如每日一次给药，起效更快，与主要竞争者相比较副作用更轻。
当候选药物在开发上的改变和在候选药物中或竞争者中得到的新的数据可是药品目标更细化和改进。
该逻辑的下一个步骤是确定发展战略，例如，有适应症先发展，哪些国家以药物上市为目标，然后确定必要的临床研究核心，以达到监管部门的批准和商业上的成功。
本章将描述一个新药的成功开发所需要的主要活动。
所有的这些活动，其中很多事相互关联的，需要认真规划和协作。
收集高质量的药品上市速度是成功的关键。
活动步骤中决定时间去注册项目管理方面是关键途径。
研究开始前的计划和准备以及对问题的监察和管理师非常重要的，以确保关键步骤的如期进行。
随着经济压力和竞争强度的增长，对公司来说重要的是探索出缩短关键步骤的方法。
使原本按顺序进行的活动同时或重叠进行，往往会使风险增大，但从节省时间中获得的分红使得这种策略变得值得。
对新药开发的关键路径通常贯穿于初始化合物的合成，亚急性毒性的研究，然后是临床的过程。
图表2显示了一个典型的候选药物的关键的活动途径。
以下章节强调了药品开发工作的目标和活动。
每个技术学科的活动大致按时间顺序描述。
在任何时间，所有这些领域的工作可能同时进行。
这时间和大量的工作成果对其它学科的工作有直接的影响。
药物研发的主要阶段是临床前（在化合物用于人体的研究），第一阶段（通常在健康志愿者的临床研究），第二阶段（在患者上初始疗效、安全性和治疗剂量的发现研究），第三阶段（在数百名患者身上的研究）。
然后按国家上市申请档案大会后的监管部门进行审查。
3 Chemical development(化学发展)候选药物的迅速发展依赖于有用的足够数量的化合物。
化合物的纯度需要达到一定的标准，以便于它的安全使用（毒理学），医药和临床研究。
最初，化学家将做从小试到中试来调查几种不同的方法对化合物的生产，以确定最适合的合成路线。
这最佳合成路线也许有几种因素组成，例如，最有效，最安全或者产生的废弃物最小。
分析最终产物，中间体和杂质在确定最好的合成方法起重要作用。
持续发展过程和保证药物纯度对分析方法的进展和有效性来说是非常必要的。
在某些情况，杂质量高到无法接受，需要纯化工艺程序，或者对合成路线也要重大的变更。
这主要目的是确保化合物结构是已知的，而且最终原料是越纯越好。
作为一种候选药物的发展，要准备大量的化合物。
这大量的原材料需要不同的试验，常依赖于药物的实际功效，以及化合物的剂型来决定的。
实验场所可被看成一个小型的生产步骤。
在转移到一种植物之前，广泛评估和化学测试以确保任何危险性的变化。
产品被优化，尤其注意发展环保化的废弃物处置方式。
大量商业化药品的生产，一旦批准上市，将会在更大场地或注册过的厂房进行。
4.制剂开发药物剂型是病人的服药方式。
剂型种类是非常多的，从贴剂到吸入剂到用于鼻子的气雾剂。
更为常见的剂型包括口服片剂，胶囊，液体剂型，局部软膏，乳膏和注射剂。
这些剂型或特殊药物的剂型选择最终会被定义。
有时更多简单剂型，例如口服溶液，在早期临床研究中被人类选用。
这也许在高风险药物发展过程中节省了时间，节约了投入资本。
在后期临床研究中以预期销售的形式使用。
不管是何种剂型，药物与其他材料的组合都必须满足一定标准。
最重要的一点是有足够的稳定性。
确保2-3年是稳定的。
剂型的稳定性将决定它的保存期限和建议储存的条件。
之前保存期限的发展也许被限制在几个月。
这将不是问题，只要它在药物临床研究中足以充分使用5 药理学在给人用候选药物前，对该药物的主要药理作用进行大量的研究。
人体系统研究包括心血管，呼吸系统，神经系统；对人体行为的影响同样要研究。
实验有时是看看药物是否会干扰其它药物，因为他的特殊使用或他们的正常使用，很可能伴随着候选药物同时发生。
任何药物的协同作用或拮抗作用应该被研究调查，并向服用药物的人发出必要的警告。
（可能需要进一步的临床研究调查，任何潜在的或被证实的药物的相互作用可能标注在标签上）。
在过量的药物使用的管理中识别出一种常用的物质是适当的，特别是当候选药物的治疗窗是窄的。
6 安全评价动物毒理学实验的目标说明了药物对人的作用是拒绝毒性化合物，识别潜在的靶器官和不良反应作用的时机。
这意味着，在早期人类研究时应特别注意监测这些器官和组织。
重要的是确定毒性作用是可逆或不可逆的，是否可以避免的，若有可能，弄清毒理作用的机制。
将药物的反应与人体的血液浓度和各种动物的血液浓度相关联同样重要。
毒理学研究所需的候选药物在人体的作用效果将与被提议的在服药途径和治疗持续时间的临床研究相关联。
服药剂量的大小和频率，毒理学研究的持续时间是允许药物在人类中测试的主要决定性因素。
国家包括美国、英国、澳大利亚和北欧国家，有涉及的在人的毒性研究两个物种所需要的长度，允许治疗期间的监管指引。
指导方针的要点被后面的章节所引用。
最初，日益增长的剂量的物质的药理作用建立在小动物的急性毒性研究上，通常用两种不同口服方式。
结果提供一种向导通常是用来测试惯性毒性试验的最大剂量，增加剂量水平并鉴定靶器官。
后续亚急性毒性测试的主要目标是决定毒性在动物体的延长，作为人类了解引起的不良反应，是否具有充分的耐药性。
在前两种化合物（非咀嚼类动物）被要求2到4个星期的研究（日常剂量），使用与人类管理的相同路线。
三种剂量水平通常是重要的，低剂量应该是预期的治疗剂量效果，并且最高剂量能够证明一些毒性。
一般的指导评估新的化学物质实体，将毒理学的最低限度时间为14天都必须持续单剂量的调查，这通常是志愿人员在临床一期阶段。
为期30天的毒理学研究需要持续7至10天的临床研究。
临床研究超过7至10天，30天或更多的时间，则需要至少90天的毒理学研究。
这些规定说明有必要去计划提前药物的开发。
今后临床试验的近似时序需要考虑，以便提前安排，并进行相应的毒理学研究，以维持临床程序，避免延误。
两种类型的安全测试时可用来检测（能在人体产生肿瘤的）候选药物的功能。
第一类是短期的体外遗传毒性试验，例如细菌测试。
第二类是类似于在小鼠和大鼠上进行长期的动物致癌研究，他们往往需要二年及长期间覆盖动物的大部分寿命。
使用小鼠和大鼠是因为他们的寿命相对较短，尺寸小，可以随时提供。
此外，这些积累了关于自发性疾病和特殊性肿瘤知识，对解释定义有特别大的帮助。
长期毒理学和致癌研究室为了获得测试认可和最后供市场产品长期管理。
这些研究可能需要在后期的潜伏期，临床阶段初期为支持临床培训。
长期毒理学研究通常包括6个月毒理学学习和这两物种（非咀嚼类）中12个月的学习。
任何在中毒之前发现可以更进一步地调查，例如额外酶在血液样本中的检测。
生殖毒理学涉及研究化合物在生殖能力，胎儿的异常情况，出生后发育情况的效果。
已届生育年龄的妇女对其临床研究，监管当局畸形学研究需要来自老鼠和兔子两种实验数据，同时也需临床男性志愿者数据。
男性试验者临床研究没有生育数据。
繁殖化合物在公开地点和研究计划阶段不同于生殖循环周期。
畸形学研究被计划去查明胎儿异常情况，生殖力研究学去研究化合物在生殖性能方面的效果，出生前后的研究是去研究幼儿的发育。
