In the nature, most male animal ratio pantheress animals are all beautiful, for example the Cape of the" mane" hair, hart and the rich in hues feather of the male peacock of the male lion.

In order to inquire the causes of occurrence of lipoid pneumonia in rat that were raised in standard SPF animal reproductive area, we used self-reproducing standard SPF rats, male 50 and female 50. All of the rats were divided into 10 groups, raised in standard Barrier system, and fed the standard diets imported from U.S.A.. All animals were divided into 4 stages to sacrifice. Autopsy, histopathological and blood biochemical examination were made at each stage. The results reveal that no lipoid pneumonia were found to occur in the 5, 10 and 26-week-old groups of male and female rats. 40% of male and 60% of female were found to occur slight focal lipoid pneumonia in the 52-week-old groups of rats.

利用成大医学院实验动物中心生产的标准无特定病原大白鼠雌、雄各50只分成10组，在屏障系统中进行实验，使用美国进口的标准实验动物饲料餵食，在一年中分四期剖检，并做病理组织学及血液生化学观察，分析比较结果显示5，10及26周龄的雌、雄大鼠皆未发生类脂质性肺炎。52周龄雌大鼠有60%，雄大鼠有40%观察到患有轻度局部性类脂质性肺炎。

A spotted deer buck attends to a doe in the Central Zoo of Kathmandu, Nepal. Opened in 1932 as a place to house the private animal collection of the current prime minister, the zoo is now run by a non-profit nature conservation trust.

在尼泊尔的加德满都动物园中，一只雄梅花鹿正在照料一只母鹿。1932年，当时的首相将其私人动物收藏开放，现在这个动物园由非盈利性质的动物保护组织托管会经营。

So we adopted the isotope marking method in order to know the distribution of BBP in male and female mice. The result indicated 〓H-BBP presented the first-order kinetics and matched the open two-compartment model. Distributional half-life was about 20 minutes and eliminable half-life was about 6-7 hours. As α(the speed constant of distributional phase) was about ten times β(the speed constant of eliminable phase), this compound had a fast distribution and a low elimination.

为了揭示BBP致毒有明显性别差异的原因，采用同位素标记方法示踪BBP在雄、雌动物体内的归趋，结果表明：BBP在动物体内呈一级动力学线性过程，符合二室开放模型，分布半衰期为20min左右，消除半衰期为6-7hr左右，分布相的速度常数α是消除相的速度常数β的10倍左右，说明该化合物在体内的分布较快、消除慢的特征。

The mammalian genus Microtus provides an excellent model for investigating the evolution of social behaviour.

属于这一类的动物包括草原田鼠，但与其密切相关的草地田鼠则属于占绝大多数的多配型社会结构类别，即一雄多雌或一雌多雄。

Oocyte samples from one group were collected to detect the presence and integration of HBV DNA within cells and chromosomes using PCR, Southern blot, dot hybridization and fluorescence in situ hybridization. The female animals from another group were mated with their normal males, respectively. Their zygotes, 2-cell embryos were collected to detect the integration of HBV DNA in the female pronuclei of zygotes and the replication and expression of HBV genes in the 2-cell embryos using FISH, RT-PCR and immunofluoresence assay.(1) PCR detected positive bands in the tested oocyte samples fromgoldon hamster and mice. Southern blot revealed clear hybridization signals in PCR products.

研究用金黄地鼠和小鼠建立实验动物模型：将卵巢内注射HBV DNA的实验动物分成两组，一组注射后进行超排卵，收集卵巢和输卵管的卵母细胞，用PCR、Southern杂交，斑点杂交和荧光原位杂交(fluorescence in situ hybridization、FISH)检测HBV在卵母细胞内的存在和染色体上的整合；另一组超排雌鼠与正常雄鼠合笼，收集受精卵和2-细胞胚，用FISH、RT-PCR和免疫荧光检测技术分别研究HBV基因在受精卵雌原核上的整合以及在2-细胞胚中的复制与表达。
