Because the objects of medicine are the "animate things", composed of active organs such as hair, skin, muscle, bone, marrow, nerve, blood, water, blood vessel, brain, heart, liver, lung, pancreas, spleen, kidney, stomach, intestine, gallbladder, bladder, nose, ear, eye and sexual organs and the above mentioned active organs can be divided into living matter of different kinds of cells; thereinto, men have penis, testicle and epididymis, spermaduct, sperm, breast undevelopment, androgen production etc.

因为，医药的对象是人类为"活物"，人类均由毛、皮、肌、骨、髓、神经、血液、水液、血管、脑、心、肝、肺、胰、脾、肾、胃、肠、胆、膀胱、鼻、耳、目、两阴等活性组织器官组成。前述活性组织器官还分有各种不同细胞的生命物质等。其中，男人有阴茎、睾丸和附睾丸、输精管、精液、乳房不发育、产生雄激素等。

Methods The circulating testosterone level of BPH patients and rats was decreased by administration of medroxyprogesterone and stilbestrol as well as castration. Using RNA dot blot hybridization technic, we detected the Bcl-2mRNA expression in human BPH tissue and rat prostate under different level of androgen.

分别通过服用药物和切除睾丸改变BPH患者和大鼠机体雄激素水平，采用mRNA斑点杂交技术，检测不同雄激素水平下的人BPH组织和大鼠前列腺组织Bcl-2 mRNA的表达情况。

The regulation of estrogen on irrational attacks mainly in the following categories : testosterone, cortisol.adrenocorticotropic hormone and adrenocorticotropic hormone, etc..

激素对非理性攻击行为的调节主要集中于以下几种：睾丸酮、皮质醇、肾上腺皮质激素和促肾上腺皮质激素等。

Recently insulin like hormone 3 is a hotspot of concerning affecting gubernacular development and testicular descent.

胰岛素样激素3是近年来倍受关注的影响睾丸引带发育和睾丸下降的重要因素，本文就相关进展进行综述。

The Research of the equine diseases and the Analysis of their reasons in Henan Province;2. Epidemiological investigation about equine tumors in Gansu province;3. The results showed that prepubertal orchidectomy of the equine resulted in a slight but not significant increase in the number and percentage of gonadotrophs,but significantly increased the average area of .

利用免疫组织化学和形态计测学的方法，观察了 7匹公马和 6匹在 1～ 2岁期间被摘除了睾丸的阉割马的脑垂体前叶促性腺激素细胞的数量和面积，同时利用放射免疫分析方法检测了血浆中垂体促卵泡激素和垂体促黄体激素的水平。

Total effective rate was 90.9%, with 17 CR, 3 PR and 2 deaths. The result showed that the orchiectomy can lower the serum level of androgen, and Flutamide can block the male hormone receptor in the target cell membrane of prostate tissue,...

结果表明氟他胺是一个单纯抗雄激素的非类固醇化合物，对前列腺组织靶细胞膜上的雄激素受体有特异性阻断作用，能抑制雄激素依赖性肿瘤细胞生长，切除睾丸能降低雄激素水平，两者产生协同作用，提高疗效。

Each male ratwas paired with 2 female rats in proestrus when administration terminated. Femalerats were examined the next morning for the presence of sperm in vaginal smears andunderwent a cesarean section on day 13 of gestation. Then the reproductive indiceswere calculated as follows: copulation index, pregnancy index, and fertility index,which can evaluate male fertility directly. The sperm motility and morphology wereevaluated by computer-assisted sperm analysis, moreover, the caudaepididymal sperm ultramicrostructure were analyzed by transmission electronmicroscope, which can evaluate the influence on sperm maturation bydutasteride ; sperm survival rate was assessed by SYBR-14 and propidium iodidefluorescent staining; serumal dihydrotestosterone and testosterone of ratswere detected by enzyme-labeled immunoassay, which can evaluate the effecton androgenic levels; the weights of testes and epididymides, were determined byprecise electronic balance; histological examination of above tissues were evaluatedby HE staining and TEM, which can evaluate treatment on histology of reproductiveorgans by dutasteride.

给药结束后雄鼠与处于动情前期的雌鼠按2：1合笼，计算雌鼠的交配指数、受孕指数和生育指数，直接评价雄鼠生育力；采用计算机辅助精子分析系统分析大鼠附睾精子活力和形态，在此基础上合并使用透射电镜技术对各组附睾尾部精子进行透射电镜分析，评价度他雄胺对大鼠精子成熟的影响；采用SYBR-14和propidium iodide双重荧光染色计算精子存活率；采用Elisa法测定大鼠睾酮(testosterone， T)和双氢睾酮(dihydrotestosterone， DHT)血清浓度，评价度他雄胺对雄鼠雄激素水平的影响；采用精密电子天平对各组睾丸、附睾、前列腺和精囊进行称重，评价度他雄胺对大鼠生殖器官重量的影响；采用HE染色法对各组睾丸和附睾进行组织学分析，同时采用透射电镜技术对附睾上皮细胞超微结构进行分析，评价度他雄胺对大鼠主要生殖器官组织学的影响。

Hormonally induced hair loss takes place when an enzyme starts to convert the hormone testosterone on the scalp to its less useful version,dihydrotestosterone, or DHT.

激素引起的脱发，当一种酶开始把睾丸酮转变为双氢睾丸酮时，头皮就会被大量的双氢睾丸酮占领，然后攻击毛囊并使它缩小，甚至完全消失。
