试验动物

Five species of animal (pig, goat, dog, rabbit and chicken)which representate polyphagia,ruminant, sarcophagy, gnawer and bird species respectively were used as experimental subjects.

本试验选取五种动物为试验对象，分别代表杂食动物、反刍动物、肉食动物、啮齿动物和禽类。

The results showed that when the proportion of the resistant subpopulation within the h-VRSA was low, te level of the toxic factor and its pathogenicity to animals had no difference from that of the standard strain. If proportion of the resistant subpopulation increased the level of coagulase and lecithinase changing from positive from negative and the ring of hemolysis disappeared. The speed of proliferation of the organisms in the animal slowed down and the LD50 increased.

结果 当试验菌株中耐药亚群的比例较少时，其毒力因子及动物致病性检测结果与金葡菌标准菌株无显著差异；随着试验菌株中耐药亚群的比例增加，表现为血浆凝固酶、卵磷脂酶由阳性转为阴性，血琼脂平板上溶血环消失，细菌在动物体内增殖速度减慢，对动物的半数致死量(LD50)增加。

White rabbits were used as the animal for testing gonococcal infection site and infecting dose.

用大白兔作为淋球菌感染部位和感染量的试验动物。

Using true metabolizable energy method to evaluate the available nutritive value of acorn kernel, while maize and rice were used as control.

以京白种鸡作试验动物，以玉米、稻谷作对照，采用鸡真代谢能法研究野生经济植物资源橡籽仁的可利用营养价值。

Many factors such as surface area, amount, chemical characterization, surface-coated condition, freshness and variety and category of experimental animal all affect their toxic intensity. This article studied the acute toxicity of Fe3O4 nanoparticles of non-modified and modified on ICR-mouse by douching stomach.

纳米颗粒的表面积、数目、化学性质、表面包被情况、新鲜度及试验动物的品系、种属等等方面的差异均影响纳米颗粒的毒性作用，本实验将自制的未经改性和经油酸钠改性的Fe3O4纳米颗粒对ICR 小鼠的口服急性毒性进行了研究。

In order to simply the method, we further propose using magnetic stirring with weighted ring in stead of argon sparging; using air-circulated incubator in stead of water bath for better observation and sample collection; using centrifuging in stead of filtration for extract pretreatment; using one phase of simplified bioaccessibility extraction method instead of the two-phase method for a better estimate to the in-vivo method.

爲进一步简化试验方法，建议将开放式反应槽改为密闭式；使用可调速磁力搅拌及具载重环磁石，取代昂贵之氩气搅拌；将水浴温控改为气控式，以利试验观察与采样。此外，小肠相萃取不使用吸附剂，萃取液前处理利用高速离心取代压阻较高之过滤方式。本研究二阶段试验之生物有效性皆低估动物试验RBF，建议可将二阶段胃肠体外试验方法改为单相一阶段生物有效性萃取(simplified bioaccessibility extraction， SBET)试验方法。

Rats were randomly divided into 2 groups. There are control group alkaline reduced water group.

以20周龄雄性SHR大白鼠为试验动物，将大白鼠分为二组，分别为纯水组碱性电解水组。

The choice better body situation and the age body weight more consistent Guanzhong -hybridised goats and Small tail han sheeps each 20 were the experimental animal, all divided into two groups according to the age and the body weight, separately took the experimental group and the control group, each group of 10 ewes.

选择体况较好且年龄体重较一致的关中杂交奶山羊和小尾寒羊各20只为试验动物，按年龄和体重随机分成两组，分别作为超排组和对照组，每组10只母羊。

Wethers with permanent rumen fistula were used to determine concentration of plasma copper, activity of cuproenzyme, apparent digestibility of copper, and disappearance rates of DM and NDF of Chinese wildrye in sheep given different copper supplements to diets with low or high molybdenum. All sources provided 16 mg of added Cu/kg of DM. Molybdenum was added as sodium molybdate.

2利用安装有永久性瘤胃瘘管的杂交一代羯羊作为试验动物，采用单向分类设计，在不同钼水平下通过测定血浆铜浓度、含铜酶活性、铜表观消化率、羊草干物质及NDF消失率，比较不同饲料铜源对绵羊铜代谢和粗料消化能力的影响，铜的添加水平均为16mg·kg~(-1)，钼的添加形式为钼酸钠。

The solubility of Cu from Cu oxide, Cu sulfate, tri-basic copper chloride, Cu lysine, and Cu proteinate was determined in deionized water, dilute acid or buffer. Twenty crossbred (Poll Dorset X Small Tail Han-yang) wethers were used to assess the effects of copper sources on concentration of plasma copper in sheep. All sources provided 8 mg of added Cu/kg of DM.

研究主要分三部分进行：(1)选用硫酸铜、氧化铜、碱式氯化铜、赖氨酸铜和铜蛋白盐五种铜源，利用不同溶剂模拟绵羊消化道的不同环境，对各种铜源的溶解性进行分析，并用20只杂交一代羯羊作为试验动物，采用单向分类设计，探讨各种铜源对绵羊血铜代谢规律的影响，各种铜源的铜添加水平均为8mg·kg~(-1)。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
