Results: 1.Empirical study: The changes of learning and memory performances and hippocampal morphology were related to ageing. Both short-term and long-term administration of excessive glucocorticoids induced the decrease of learning and memory performances and hippocampal neurodegeneration. Adrenalectomy operated during both infancy and senectitude inhibited the hippocampal structure and function.

结果：1、实验研究：动物学习记忆能力及海马的形态与增龄密切相关，短期、长期给予过量糖皮质激素可造成海马退行性改变和学习记忆功能的降低，幼年期糖皮质激素剥夺可影响动物神经发育和功能，老年期长期糖皮质激素剥夺可加重动物海马退行性病变和学习记忆能力下降。

Skatole is harmful to human animals as well as environment. When human and animals take food which contains skatole or can be converted into skatole, skatole will inevitably interact with digestive enzymes. Skatole absorbed through skin may also interact with digestive enzymes in human and animals. So we studied the effect of skatole on three important digestive enzymes.

粪臭素对人、动物及环境均有一定的危害作用，含有粪臭素或可以转变为粪臭素的外源性食物进入体内后，粪臭素将不可避免地与动物和人体内的消化酶发生作用，人和动物通过皮肤吸收的来自外界环境中的粪臭素也有可能与体内的消化酶发生作用，因此我们研究了粪臭素对几种重要消化酶部分性质的影响。

Basic information such as family tree, medical history, age and weight are entered by studbook keepers, then sent to a central location where the data is analyzed and converted into a "master plan" for breeding.

动物管理员们在"血统簿"中记录动物的家谱、病史、年龄和体重等基本信息，然后将这些信息传输到一个数据中心。研究人员对这些信息进行分析后，会形成一套整体的动物繁殖规划。

The book introduces the animal models representing natural infections ranging from uni- to multicellular and from endo- to ectoparasites in fish, chickens and mammals, including structural and physiological aspects of cell death; Role of apoptosis in non-mammalian host-parasite relationships; thionine-positive cells in relation to parasites; animal models for the study of innate immunity; interaction between sea lice and their hosts; pathophysiology of salmonids cryptobiosis and glossina-transmitted mammalian trypanosomiasis in livestock; avian coccidiosis; interactions betweem fish hosts and monogeneans.

该书介绍了鱼类，小鸡和哺乳动物从单细胞到多细胞和从内寄生虫到外寄生虫的天然传染的动物模型，包括细胞死亡的结构和生理学方向；非哺乳动物宿主和寄生虫关系中细胞凋亡的作用；硫堇阳性细胞与寄生虫的关系；用于先天免疫研究的动物模型；海虱与其宿主的相互作用；鲑鱼隐生想象的生理病理学和家畜中舌蝇传播的哺乳动物锥虫病；鸟类球虫病；鱼类宿主与单殖亚纲动物的相互作用。

We currently have 40,000 sq ft of modern biomedical research facility, including a 10,000 sq ft animal vivarium able to house immunodeficient small animals and large animal species.

公司总部位于美国硅谷，同时在北京拥有4000平方米完整、独立的现代化生物医药研究基地，其中包括1000平方米符合国际标准的动物房，有足够空间、能力饲养小动物及大动物。

The km mouse had lower white blood\|cell count than that of BALB/c and C 57 BL/6J inbred strain;The BALB/c inbred strain had lower eosinophil and basophilic cells tha...

小鼠具有很多的品种品系，是实验动物中培育种类、品系最多的动物，也是医学研究领域应用最广泛的动物。因此

Traditionally, the systematic position of the Bryozoa phylum is regarded as transitional between the protostomes and the deuterostomes.

一般认为它是介于原口动物和后口动物之间的过渡类群。但是，近年来的分子系统学研究已经证实了它的原口动物归属。

From Chaotianmen to Zigui,the Shannon-Weaver diversity index of phytoplankton changes undeely.4 the impact of sediment deposition on zooplankton in the waters studiedAccording to the results of the experiment, we had learnt that the species composition of zooplankton sampled had the same tendence-the species was from less to more, and the biomass was also gradually increasing. Particularly Copepoda had increased significantly in the type and quantity. The main of zooplankton at each sampling situs were protozoa and rotifers.

朝天门江段到秭归江段的浮游植物的Shannon-Weaver多样性指数呈波浪式变化，整体有下降趋势。4研究水域泥沙沉降对浮游动物的影响从本次实验的结果来看，四次采样浮游动物种类组成都有同一个趋势：种类由少到多，生物量也逐渐增大，特别是桡足类在种类和数量上都增加明显，各采样点的浮游动物以原生动物和轮虫为主。

The model had good duplicability and stability through the method of establishing the animal model in which the simple operative method,small wound and convenient nurse was obtained so easilyis that the animal model was spread easily.The study of the change of short and long period was made to provide the experimental base and reason through the animal model.

结论通过自制冲击器冲击兔右侧髋臼软骨，模拟冲击伤机制，初步建立髋臼软骨冲击伤实验动物模型并量化冲击能，通过统计学分析，大体和组织病理学检查，并与国外动物模型相比，本模型重复性和稳定性好，术式操作简单，创伤小，护理方便，易于推广，为研究活体动物髋臼软骨冲击后的短期和长期变化提供实验基础和依据。

Therefore, how to determine inapparent infection and differentiate between infected and vaccinated animals is required for FMD prevention and control.

因此，如何判断隐性感染动物以及区别注苗动物和自然感染动物是口蹄疫防制技术研究的一项重要内容。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
