The dosage was geared down to a level which would work on the infected cells but not upset their metabolism 药剂量要减少到既能对受感染细胞起作用，又不损害它们的代谢作用。
Besides its metabolic functions , clinical applications and advance of pharmacological research , process of preparation are emphatic reviewed 本文综述了sam的代谢作用、临床应用和药理研究进展，并重点介绍其制备方法。
Metal speciation and valence variation , transport processes , and microbial metabolism are three important ingredients for metal and radionuclide remediation 金属的种类和价态变化、转移过程以及微生物代谢作用是对金属和辐射生物修复的三种重要的组成部分。
Living organisms also are thought to require a degree of biochemical autonomy , carrying on the metabolic activities that produce the molecules and energy needed to sustain the organism 一般还认为生物也必须具备一定程度的生化自主性，能够进行代谢作用，制造分子和能量来维续这个有机体。
Thus , due to the action of ultra violet rays on the skin , substances are produced in the skin which get into the blood and accelerate the processes of metabolism in the various organs of the body 因此,由于紫外线在皮肤的作用,皮肤里产生一些物质进入血液,可促进人体各个器官的代谢作用。
There were limited reports about the metabolism catalyzed by ugt1a9 . ugt1a9 mainly catalyze the glucuronidation of hydroxyl to produce o - glucuronide . besides , ugt1a9 also catalyze the glucuronidation of carboxyl and hydroxylamine compounds 有关ugt1a9的代谢作用研究不多，从文献报道来看， ugt1a9主要催化羟基上的缀合反应，形成o -葡醛酸苷，此外它也能与羧基、羟肟酸形成葡醛酸苷。
It is thought that extracellular gsh protects the cells from oxidants released by inflammatory cells whilst intracellular gsh neutralizes the ros produced as a result of normal cell metabolism , as well as detoxifying xenobiotics ( 4 ) 研究者认为细胞外的谷胱甘肽可保户细胞免受发炎细胞所释放氧化剂的攻击，而细胞内的谷胱甘肽可中和正常细胞代谢作用以及共栖生物解毒作用所产生的具反应性氧核素。
Extensive pharmaco ? epidemiological study of gsh metabolism and standardized methods of measurement of intracellular gsh applicable in clinical trials are needed in order to better define the clinical application of this new type of therapy 因此，需要对谷胱甘肽代谢作用进行详尽的药物流行病学研究，并建立应用于临床试验中测量细胞内谷胱甘肽水平的标准方法，来进一步规范这个新的治疗方法的临床应用。
Now transgenic cell lines that express the protein encoded by ugt gene were broadly used instead of liver microsomes . the enzyme expressed in cell lines helps to realize the function of a specific gene and will provide direct information related to the isozyme interested ‘为解决上述问题，国际上人们己经广泛采用建立各种ugt转基因细胞系的方式试验，在明确基因构成的倩况下直接获得由特定基因所表达的ugt同工酶， fi什对性地研究该酶对药物的代谢作用。
Secondary treatment is the biological treatment that controls the environment for growing enough quantity of microorganisms to degrade organic substances in the wastewater followed by separating the microorganisms from the treated liquid to achieve the objective of purification . the biological treatment can be either aerobic or anaerobic 二级处理通常系指生物处理而言，主要原理在于控制及培养一定数量之微生物，利用微生物生长代谢作用，来分解去除废水中的有机物，再将处理水和微生物分离，并废弃增殖过剩之微生物量，而达到净化水质之目的。
