The contents are mainly divided into three parts: The first part describes mechanism and metabolism rule of natural products and its classification ; The second part is about the growth and development of plants and their mutual relationship, natural biological active substances which are produced in the course of defending plant diseases and insect damages. The third part is not only the function and principle of medicine, anticancer and antioxygen activity of different kinds of natural products such as resin ,essential oil, high molecule, grease and so on but also their application. The fourth is security problem of Plant Natural Products. Through the lessons, we can correctly understand and use the relationship between plants and environment.

其课程分为13章，内容主要分为4大部分，一是阐述植物天然产物的发生机理和代谢规律，介绍相关主要植物种类，并对天然产物进行化学分类；二是讲述植物天然产物和自身生长发育之间的关系、天然产物如何影响植物之间的相互关系、以及植物如何利用天然生物活性物质抵御病虫害的威胁；三是详细描述了各种天然产物，如植物自身生长发育过程中所产生的活性物质、植物与其它生物之间的相互关系中所产生的生物活性物质、植物毒性物质、植物药理活性物质、植物抗生物质、植物树脂、植物精油、植物高分子、植物油脂、植物抗氧化活性成分等，并阐述它们的药理活性、抗癌性、抗氧化性等对人类健康起作用的的功能和原理；四是提出了植物天然产物的安全性问题，并介绍相关案例和介绍相关法规；在此基础上还专门讲述了树脂、精油、高分子、以及油脂类等天然产物的应用。

This procedure can be influenced by a lot of factors, such as hormones, growth factors, et al. Only very few follicles will develop into dominant follicles and ovulation and more than 99% turn atresic. Xiang pigs are a world famous breed of the miniature pig mainly distributed in Guizhou and Guangxi provinces of China.

同时，卵泡的生长和发育也是一个高度协调的生理过程，受多种因素（激素、生长因子、芳香化、金属离子、物理及化学刺激等）的影响和控制，少数卵泡最终发育为优势卵泡并排卵，99%以上的卵泡都将发生闭锁。

Periaqueductal gray neurons exhibit increased responsiveness associated with audiogenic seizures in the genetically epilepsy-prone rat.

总之，听源性惊厥发作诱导PAG内大量神经元表达c-fos基因，揭示了PAG内神经元功能活动的剧烈改变，N'Gouemo［12］的电生理研究也发现，听源性惊厥易感大鼠PAG内许多神经元表现为异常的高反应性状态，而且出现与强直相关的神经元异常放电，这些都进一步说明PAG参与了听源性惊厥发作过程，但其中的神经化学机制尚需进一步探讨。

Immunocytochemistry further revealed that the proteins encoded by these genes accumulated inthe elongating and condensing generative nucleus during development of bicellular pollen, and weremost abundant in the two sperm nuclei within an elongated pollen tube.

免疫细胞化学进一步显示，该编码的蛋白是由这些基因的累积inthe拔节和冷凝生成核的开发过程中bicellular花粉，并weremost丰富，在两个精子细胞核内的一个狭长花粉管。

UV-Vis and continuous variation plot method were used to study the complexation of γ-cyclodextrin with bromocresol green, and the stoichiometric ratio of the complexation was to be 1∶2. Thermodynamic analysis results show an inverse relationship between temperature and complexation constant, and the change of enthalpy, entropy and free energy of the complexation were -39.988 kJ/mol, 86.400 J/ and -14.245 kJ/mol, respectively, which indicating that hydrophobic effect was the main force to form the complexes.γ-Cyclodextrin and bromocresol green complexes were examined by nuclear magnetic resonance, infrared spectrum and molecular modeling analysis, and was may be the group included in γ-cyclodextrin.

采用紫外-可见分光光度法和等摩尔连续变化法研究了γ-环糊精与溴甲酚绿的包合作用，确定了包合物形成的化学计量比为1∶2；采用热力学方法分析了温度与包合常数之间的关系，计算了包合过程的焓变、熵变及自由能变化分别为-39.988 kJ/mol， 86.400 J/和-14.245 kJ/mol，这表明疏水作用力为主要驱动力；采用核磁共振、分子模拟和红外光谱法对包合物进行了研究，确定了包合物的形成，分析认为这可能是基团进入γ-环糊精腔内导致增色效应。

TEM shows that drying by direct heating might result in hard aggregation of the tourmaline powder, while hard aggregation might be avoided by azeotropic distillation. Raman spectroscopy reveals that there are O_H and C_H on the surfaces of the tourmaline powder obtained by azeotropic distillation, which indicates that butoxy is chemically adsorbed on the surfaces of tourmaline particles, but not adsorbed on those formed by direct drying. X_ray powder diffraction shows that the intensity of diffraction peaks decreases after grinding. There is no damage to the tourmaline crystal lattice in the process of direct heating, azeotropic distillation, or ultrafine grinding.

透射电镜分析结果表明，直接加热脱去水或正丁醇会使电气石超细颗粒发生硬团聚，而共沸蒸馏法则可有效防止硬团聚的产生；拉曼光谱结果表明，共沸蒸馏法制备的电气石粉末表面存在O—H和C—H键，说明正丁醇在颗粒表面为化学吸附，而直接干燥法得到的电气石粉末表面则没有；X射线粉晶衍射结果表明，研磨过程降低了粉末衍射峰的强度，但直接加热干燥和共沸蒸馏干燥均未破坏电气石的晶格结构。

Occurrence,migration,tissue localization and quantity changes of CD3+,CD4+,and CD8+ T lymphocyte subpopulations in chicken caecal tonsil was examined immunohistochemically by using the CD3,CD4 and CD8 monoclonal antibodies.

通过免疫组织化学方法，应用CD3、CD4和CD8单克隆抗体研究了CD3+ T淋巴细胞及CD4+和CD8+T淋巴细胞亚群在鸡盲肠扁桃体中的出现、迁移、组织定位分布及数量变化规律等一系列发育过程。

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
