医学英语名词解释

Medicine: Medicine comes from the Latin ,mederi -to heal ,which is at the core of medicine. There are many branches of medicine ,but all have something in common. They all seek to heal,from dermatology ,which ties to heal the skin,to psychiatry, which tries to heal the mind.

Scan: In the Magical context, scan is used for the use of ultrasound to provide a visual display of the internal organs and other body structures. In this context the word indicates a means of finding information visually.

Anatomy:Anatomy is the study of the appearance of the structures of the human body including gross anatomy and gross anatomy and microscopic anatomy.

Pharmacology :Pharmacology is the study of drugs, what they are, How they work and what they do. You will look at how the functions of organisms and live tissues are modified by chemical substances.

Endocrine system:Endocrine system is to regulate the various organs within the body and it does this primarily by using hormones , which are produced by glands in the body. Endoscope:Endoscope is a flexible tube inserted into an opening in the body, which is manipulated so that it gets close to the location of the tumor without the need for additional cutting.

Alzheimer's :Alzheimer's is a disease which affects mental, cognitive and motor ability and ultimately often leads to the death of the patient. It also causes considerable distress to the patient themselves and to their carers.

Hyperthyroidism:Hyperthyroidism is the condition which is caused by the effects of too much of the thyroid hormones on tissues of the body.

Physiology:Physiology deals with the functioning of the body and its internal organs;essentially it's the science of the mechanical, physical, and biochemical functioning of human in good health.

cardiovascular system: The cardiovascular system is made up of three components: blood,the heart and the blood vessels. The function of the system is to transport blood throughout the body, with the heart acting as the pump for circulation.

Disease : Disease occurs when there are variations in normal structure or function of the body, causing problems or discomfort to the patient. Disease can be caused by external factors,or genetic or other internal factors.

Prevalence : Prevalence is the overall number of people in specific populations who have been diagnosed with a disease.

Acute care:Acute care is the treatment of a disease or symptoms that require immediate attention, the care generally received by patients in Accident&Emergency.

Introduction to Physiology Introduction Physiology 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 生理学简介 介绍 生理学是研究生物体功能的科学。它研究生物体如何进行各种活动,如何饮食,如何运动,如何适应不断改变的环境,如何繁殖后代。这门学科包罗万象,涵盖了生物体整个生命过程。生理学成功地解释了生物体如何进行日常活动,基于的观点是生物体好比是结构复杂而灵巧的机器,其操作受物理和化学规律控制。 尽管从生物学整个范畴看,生物体某些活动过程是相似的——如基因编码的复制——但许多过程还是某些生物体群组特有的。鉴于此有必要将这门学科分成不同部分研究,如细菌生理学、植物生理学和动物生理学。 要研究一种动物如何活动,首先需要了解它的构成。要充分了解一个生物体的生理学活动就必须掌握全面的解剖学知识。一个生物体的各部分起着什么作用可通过实验观察得知。尽管我们对志愿者进行了许多重要的生理调查,但是实验条件需要精确控制,所以我们当前大多生理知识还是源于对其它动物如青蛙,兔子,猫和狗等的研究。当我们明确大多数动物物种的特定生理过程存在共同之处时,相同的生理原理适用于人类也是合理的。通过这种方法,我们获得了大量的知识,从而让我们对人类生理学有了更深入的了解,为我们有效治疗许多疾病提供了一个坚实的基础。 机体的基本组成物质是细胞,细胞结合在一起形成组织。组织的基本类型有上皮组织,结缔组织,神经组织和肌组织,每类组织都有各自的特征。许多结缔组织中细胞量相对较少,但是有大量的细胞外基质。相比而言,光滑的肌组织由大量密密麻麻的肌细胞通过特定的细胞连接组成。各种器官如脑,心脏,肺,小肠和肝等由不同种类的组织聚集而成。这些器官是不同生理系统的组成部分。心脏和血管组成心血管系统;肺,器官,支气管,胸壁和膈肌组成呼吸系统;骨骼和骨骼肌组成骨骼肌系统;大脑,脊髓,自主神经和神经中枢以及

药理学名词解释(含英文)

1.药物(drug)是指能够影响机体(包括病原体)功能和(或)细胞代谢活动,用于疾病 的治疗、预防和诊断,以及计划生育等方面的化学物质。 1.Drugs are chemicals that alter the function of living systems by interactions at the molecular level and can be used to prevent, diagnose and treat disease. 2.不良反应(adverse drug reaction ADR)是指上市的合格药品在常规用法、用量情况下 出现的,与用药目的无关,并给患者带来痛苦或危害的反应。 3.副作用( side effect)是由于药物作用选择性低,作用范围广,在治疗剂量引起的,与 用药目的无关的作用。 4.毒性反应(toxic effect)是由于用量过大或用药时间过长引起的严重不良反应。 5.后遗效应(residual effect)是指在停药后,血浆药物浓度下降至阈浓度以下时残存的药 理效应。 6.变态反应(allergic reaction)是药物引起的免疫反应,反应性质与药物原有效应无关, 其临床表现包括免疫反应的各种类型。致敏原可以是药物本身或药物代谢产物,亦可能是制剂中的杂质或辅剂。 7.继发反应(secondary reaction)是继发于药物治疗作用之后的不良反应。 8.停药反应(withdrawal reaction)是指患者长期应用某种药物,突然停药后发生病情恶 化的现象。 9.特异质反应(idiosyncrasy reaction)是指少数患者由于遗传因素对某些药物的反应性发 生了变化。特异质反应表现为对药物的反应特别敏感,或出现与在常人不同性质的反应。 10.依赖性(dependence)是药物与机体相互作用所造成的一种状态,表现出强迫要求连续 或定期使用该药的行为或其他反应,其目的是感受药物的精神效应,或避免由于停药造成身体不适应。 11.量效关系(does-effect relationship)药理效应的强弱与其剂量大小或浓度高低呈一定关 系,称剂量-效应关系,简称量效关系。 12.最小有效量(minimal effective does)或最小有效浓度是指引起效应的最小药量或最低 药物浓度,亦称阈剂量或阈浓度。 13.最大效应(maximal effect Emax)在一定范围内增加药物剂量或浓度,效应强度随之增 加。但当效应增强打最大时,继续增加剂量或浓度,效应不再增强。这一药理效应的极限称为最大效应,又称效能(efficacy)。 14.效价强度(potency)用于作用性质相同的药物之间的等效剂量的比较,达到等效时所 用药量较小者效价强度大,所用药量较大者效价强度小。 15.构效关系(structure-activity relationship ,SAR)药物的结构与药理活性或毒性之间的关 系称为SAR。 16.受体(receptor)是细胞在长期进化过程中形成的,对生物活性物质具有识别和结合的 能力,并具有介导细胞信号转导功能的蛋白质。与受体特异性结合的生物活性物质称为配体(ligand)。 17.激动药(agonist)是指既有亲和力又有内在活性的药物,它能与受体结合并激动受体而 产生效应。分为完全激动药和部分激动药。 18.拮抗药(antagonist)是指具有较强的亲和力,而无内在活性,拮抗药与受体结合但不 能激动受体。竞争性拮抗药(competitive antagonist)能与激动药竞争相同受体,但其结合是可逆的,竞争性拮抗药能使激动药的量效曲线平行右移,但最大效应不变。非竞争性拮抗药指拮抗药与受体的结合是相对不可逆的,或能引起受体构象的改变,从而干扰激动药与受体的正常结合,使激动药不能竞争性对抗这种干扰。增大激动药的剂量也不能使量效曲线的最大作用强度达到原来的水平。
