Results In lead poisoning group, the pathological changes in genital glands of mice were obtained; sperm count, linear movement sperm and live sperm rate decreased; the elevated motionless sperm, cacospermia and primary spermatocyte chromosome aberration rate were found. In Haierfu group, the pathological changes in genital glands of mice ameliated to different degree, sperm count, linear movement sperm and live sperm rate elevated, and motionless sperm, cacospermia and primary spermatocyte chromosome aberration rate decreased.

结果 醋酸铅染毒组雄性小鼠的生殖腺有不同程度的病理学改变，精子计数、直线运动精子数、活精子率下降，而静止不动精子数、精子畸形率和初级精母细胞染色体畸变率升高；海尔福治疗组小鼠的生殖腺病理学改变有不同程度的改善，精子计数、直线运动精子数、活精子率有所升高，而静止不动精子数、精子畸形率和初级精母细胞染色体畸变率有所降低。

objective to evaluate effect of lulongshengjing pill on the treatment of oligospermatisma with insuffi-ciency of kidney.methods 100cases with oligospermatism with insufficiency of kidney were treated by lulongshengjing pill.the therapeutic course was three months.testicular fluid routine was carried on every month.changes of testicular flu-id indexes（includes amount,colliquation time,spermatozoa density and motility rate）and procreation were observed before and after treatment.results the total effective rate was91%;cure of56;significant improvement of19;improvement of16and ineffective of9.testicular fluid indexes were significantly improved after treatment compared with those before treatment（p.01）.conclusion lulongshengjing pill was effective on the treatment of oligospermatism with insufficiency of kidney.

目的 观察鹿茸生精丸治疗肾阳虚型少精子症的临床疗效。方法采用鹿茸生精丸治疗肾阳虚型少精子症患者100例，3个月1个疗程，治疗2个疗程，每月查1次精液常规，观察治疗前后精液参数（精液量、液化时间、精子密度、活率及精子形态）的变化及生育情况。结果治愈56例，显效19例，好转16例，无效9例，总有效率91%。治疗前后精液量、精子密度、活率等项指标均有明显改善，与治疗前比较差异有统计学意义（p.01）。结论鹿茸生精丸治疗肾阳虚型少精子症具有良好疗效。

Our observations suggest that, in addition to motility, the protein phosphatase PP1 gamma 2 might play an isoform-specific function in the development of specialized flagellar structures of mammalian spermatozoa.

我们的观察表明运动性蛋白磷酸酶PP1γ2可能在哺乳动物精子的鞭毛的特异结构的发育过程中具有异构体特异的功能。

Despite of its important role during embryogenesis and reproductive development,more and more studies implied a critical role for Rhox5 on the determination and differentiation during myogenesis.

除在生殖系统的发育、精子的形成和成熟过程中发挥重要的作用外，多项研究表明其在肌细胞的发生和分化中担任重要角色，有可能作为MyoD基因的上游调控子或者和其他转录因子协同作用，调控肌细胞的早期发生和分化事件。

Objective To obtain information on the application value of percutaneous epididymal sperm aspiration and percutaneous testicle sperm aspiration in the differentiating diagnosis of obstructive and nonobstructive azoospermia.

目的探讨经皮附睾精子抽吸术及经皮睾丸精子抽吸术在无精子症鉴别诊断中的应用价值。方法采用PESA或PTSA对梗阻性无精子症组37例及非梗阻性无精子症组28例进行附睾或睾丸取精，细胞学涂片进行分析。

According to the results of semen examination, can be classified as azoospermia and severe oligospermia, oligospermia, infertility and normal sperm count, more than sperm and sperm can not afford such disease.

根据精液检查的结果，可分类为无精子症、重度少精子症、少精子症、精子数正常性不育症、多精子症以及精子无力症等。

Tell from angle of doctor of traditional Chinese medicine, oyster can make the hydrosphere inside body expedite, this meant the nephritic load that supervises hydrosphere to reduce; Western medicine thinks, enough zinc can assure the amount of spermatozoon and character, and oyster is to contain one of provision with most zinc, eat 2 ～ everyday the zinc that round-the-clock place wants 3 ostracean enough bodies.

从中医角度讲，牡蛎能使体内水气畅通，这意味着管理水气的肾脏负担减轻了；西医则认为，足够的锌能保证精子的数量和品质，而牡蛎是含锌最多的食品之一，每天吃2～3个牡蛎就足够身体全天所需的锌。

Pregnancy ratewas significantly higher in women receiving 1 to 3 cycles of treatment than those receiving more than 3 treatmentcycles. Conclusion: Pregnancy rate after IUI was related to thickness of endometrium,time of IUI, diameterof fallopian tubal ampullae,density and motility of sperm after washing.

影响IUI结局的主要因素是：子宫内膜的厚度、IUI治疗的时机、输卵管壶腹部的直径、输卵管伞端距宫角的距离、洗涤后精子的密度和动力。

The result showed that: 1 Gill epithelium nucleus major-axis size, hemolymph nucleus diameter in the connective tissue of mantle and labial palps were significantly (P＜0.001) larger in triploids than in diploids, no significantly differences were found in rectum epithelium height between diploids and triploids.

另外，通过组织切片、扫描电镜和透射电镜等方法比较了二倍体和三倍体太平洋牡蛎的几种组织器官的细胞大小、鳃的表面结构和鳃的超微结构，二倍体和四倍体精子的超微结构上的差异，旨在为更好的发展多倍体育种技术、探索多倍体的快速生长机制提供理论依据。
