Unit SevenText A BiopharmaceuticsBefore the reader can appreciate the meaning and clinical significance of biopharmaceutics, it is necessary to introduce the concept of drug bioavailability.1. appreciate [ə'pri:ʃ ieit] vt.欣赏；感激；领会；鉴别vi.增值；涨价2. bioavailability ['baiəuə,veilə'biləti] n.生物利用度；生物药效率为了使读者能够理解生物药剂学的含义和其对于药物临床应用的重要意义，有必要先给大家介绍一下药物生物利用度的概念。

BioavailabilityThe therapeutic response of a drug is normally dependent on an adequate concentration of the drug being achieved and then maintained at the site or sites of action of the drug. In the case of systemically acting drugs ( i. e. drugs that reach these sites via the systemic circulation) it is generally accepted for clinical purposes that a dynamic equilibrium exists between the concentration of drug at its site(s) of action and the concentration of drug in blood plasma. An important consequence of this dynamic equilibrium is that it permits a therapeutically effective concentration of drug to be achieved at its site(s) of action by adjustment of the concentration of drug in blood plasma. Strictly speaking, the concentration of drug in plasma water (i. e. protein-free plasma) is a more accurate index of drug concentration at the site(s) of action than the concentration of drug in whole plasma since a drug may often bind in a reversible manner to plasma protein. Only drug which is unbound (i. e. dissolved in plasma water) can pass out of the plasma through the capillary endothelium and reach other body fluids and tissues and hence its site(s) of action. Drug concentration in whole blood is also not considered to be an accurate indirect index of the concentration of drug at its site(s) of action since drug can bind to and enter blood cells. However, to measure the concentration of an unbound drug in plasma water requires more complex and sensitive assay methods than to measure the total concentration of both unbound and bound drug in total plasma. Thus, for clinical purposes, drug concentration in blood plasma is usually measured and is regarded as an index of drug concentration at the site(s) of action of the drug and of the clinicaleffects of the drug. However, it should be realized that this is a simplification and may not always be valid. Indeed one should not draw inferences about the clinical effects of a drug from its plasma concentration until it has been established that the two are consistently correlated. It has been assumed that the plasma drug concentration is directly proportional to the clinical effect of that drug.1. systemically [ sistə'mætikəli ] adv.有系统地，有组织地，有条理地，全身地systemic [si'stemik; -'sti:-] adj.系统的；体系的；全身的2. purpose ['pə:pəs] n.目的；用途；意志vt. 决心；企图；打算3. dynamic equilibrium [dai'næmik] [,i:kwi'libriəm] 动态平衡；动力平衡4. plasma ['plæzmə] n.等离子体；血浆5. reversible [ri'və:səbl] adj.可逆的；可撤消的；可反转的n. 双面布料6. capillary endothelium [kə'piləri, 'kæpi-] [,endəu'θi:liəm] 毛细血管内皮7. assay [ə'sei] n.化验；试验vt.分析；化验；尝试vi.鉴定；经检验证明内含成分8. simplification [,sɪmpləfə'keʃən] n.简单化；单纯化9. valid ['vælid] adj.有效的，有根据的；正当的10. draw inferences ['infərəns] 作出推论11. consistently [kən'sistəntli] adv.一贯地；一致地；坚实地12. proportional to [prə'pɔ:ʃənəl] 与……相称，与……成比例通常情况下，药物达到其作用部位、并维持足够的药物浓度，才能发挥疗效。

For example, in Western cultures brides often choose a white wedding dress, while in China the traditional wedding dress is in red. Though white has become the most preferred color for wedding gowns across the world today, this was not a widespread trend before the Victorian era. White became a popular option in 1840, when Queen Victoria wore a white gown at her wedding. The official wedding photograph was widely published, and many brides chose white to become the followers of the Queen. Many people believed that the color white symbolized virginity, though this was not the original intention. As far as the style is concerned, wedding dresses were once typically short in the front with a longer train in the back. This tendency continued until the late 1960s, when it became popular to revert to long, full-skirted designs.婚纱礼服的颜色和款式可取决于婚礼参与者的宗教和文化。
