MATERIALS: Female unmated SD rats of 4 months old, with the body mass of (225±15)g, were provided by Shanghai Experimental Animal Centre of the Chinese Academy of Sciences.

材料：4月龄未交配的雌性SD大鼠，体质量(225±15)g，由中国科学院上海实验动物中心提供，动物级别为清洁级(合格证号：中科动管第003号)。

Fifty 6-month-old unmated female SD rats were randomly divided into 5 groups: sham operated group, ovariectomized and treated with estrogen group, ovariectomized and treated with propranolol group, ovariectomized and treated with both estrogen and propranolol group, ovariectomized and treated with placebo group .

将50只健康雌性未交配6个月龄SD大鼠随机分为5组：①假手术组。②去卵巢后雌激素治疗组。③OVX后普萘洛尔治疗组。④OVX后雌激素+普萘洛尔治疗组。⑤OVX后安慰剂组。

From July 9 through July 22, 2009, APHIS, in cooperation with the California Department of Food and Agriculture and the Los Angeles County Agricultural Commissioner, confirmed the detection of four male, one mated female, and one unmated female white striped fruit flies on various residential properties in the La Verne and San Dimas areas.

从2009年7月9日到7月22日，检疫局、加州食品农业部和洛杉矶县农业专员，确认在拉维恩三个独立的住宅物业区发现了四头雄虫、一头交配的雌虫和一头不交配的白色条纹雌性实蝇。

Methods A total of 60 adult female SD rats weighing about 340g were randomly allocated into 3 equal groups: unoperated control group (n=20), sham-operated group (n=20) and ovariectomied group (n=20). Immunohistochemical methods were used to determine ER-αand ER-βin superficial and deep compartments in the uterus and vagina.

60只成年SD雌性大鼠随机分为正常组、假手术组、去势组，每组20只。8周后处死大鼠，分离摘取子宫、阴道，进行ERα、ERβ免疫组织化学染色和mRNA半定量RT-PCR检测。

Furthermore, these clinical and epidemiologic data are consistent with what appears to be a low overall breast cancer risk associated with pharmacologic unopposed estrogen exposure in postmenopausal women.

此外，在对绝经后妇女的雌性激素使用中没有出现药理性的不适，而且这两种数据都表现出较低的患病几率。

They are more reproductively successful than unpaired females.

和未配对的雌性相比，她们更能成功繁衍后代。

Males had a mean TL of 329 mm ( n = 192), females had a mean TL of 308 mm ( n = 166), and an additional 56 fish were unsexed (mean TL = 239 mm).

鱼全长范围是78～442mm ，雄性平均全场为329mm ，雌性平均全长308mm ，56条鱼未能鉴别性别（平均全长239）。

Objective To research the expression of the estrogen receptor alpha and estrogen receptor beta in uvea tissues of the female rats, and to provide molecular biology data for further studies of the relation estrogen to uvea diseases.

目的 探讨雌激素α、β受体在雌性大鼠眼葡萄膜组织的表达。

Methods Twenty-two adolescent SD female rats were selected. All rats were killed by dislocation of cervical vertebra, the eyeballs were in paraffin imbedding and made to a series of sections, using immunohistochemical method; ERα and ERβ distribution were investigated in uvea tissue of rats; and quantitied by Tanaka scores analytical method. The uteri of rats was used as positive control and PBS as negative control.

选择青春期SD雌性大鼠22只，采用颈椎脱臼处死大鼠，取眼球作常规石蜡包埋，连续切片， SP免疫组织化学方法显示ERα、ERβ在葡萄膜组织的表达；采用Tanaka记分法对ERα、ERβ进行定量分析，并设正常大鼠子宫作阳性对照；PBS代替一抗作阴性对照。

Estradiol valerate (1.2 mg·kg-1·d-1) was given to the drug group for 4 weeks by gavage in 4 weeks after ovariectomy.

4月龄SD雌性大鼠80只，分为正常组、假手术组、去势组、药物干预组，每组20只。
