精虫的

BOULE transcript levels in the testes of 41 azoospermic patients were examined by quantitative competitive-reverse transcription-polymerase chain reaction.

我们以定量竞争性反转录聚合连锁反应的方法定量 41 位无精虫症患者睪丸内 BOULE 的转录量。

This would be tantamount to a cooperation one of nature s favourite devices between the nisus formativus of the nemasperm on the one hand and on the other a happily chosen position , succubitus felix , of the passive element

这个论点也许意味着：一方面是精虫的生殖本能276，另一方面是被动因素那巧妙地选择的体位即卧在下面受胎277之间的协力大自然喜用的方法之一。

These findings lead to an MSAP/septin-mediated model for flagellar differentiation during spermiogenesis.

免疫萤光定位分析显示septin7与MSAP共同位於精虫鞭毛的基底体上。septin蛋白家族可能参与细胞质分裂及细胞形态生成等事件，因此推测MSAP/septin复合体的功能可能涉及鲤鱼精细胞之极性建立及鞭毛形成。

Fractionation of sperm proteins and in vitro polymerization of flagellar tubulins revealed that the protein might be one of the axonemal components of carp sperm.

后续的鲤鱼精虫蛋白萃取及鞭毛微管再组合实验则显示该蛋白可能是轴丝的成分之一。

One day , mr Chen finishs in the hospital after infecund disease is checked , the sperm number that beautiful female doctor wants to check Mr Chen decreases .

有一天，陈先生在医院做完不孕症检查后，漂亮的女医生要检查陈先生的精虫数目有没有减少。

MATERIALS AND METHODS: From September 1997 to September 1999, 56 patients with either infertility (36) or scrotal discomfort (20) who underwent subinguinal microsurgical varicocelectomy were reviewed. All patients were confirmed as having varicocele by pre-operative color flow mapping.

材料与方法：从1997年9月到1999年9月，回顾了五十六个或者不孕（36）或者阴囊不适（20）的患者，接受鼠蹊管下方的显微精索静脉切除手术，所有病人都采用术前彩色血流杜卜勒超音波确定诊断为精索静脉曲张；此外，以Wilcoxon等级测验统计应用於精虫变化的比较。

Professor of obstetrics and gynaecology Deborah Anderson says that Coca-cola douches were sometimes used in 1950s and 1960s America in the belief that the drink's acidity killed sperm.

妇产科教授安德森说，可口可乐冲洗法在1950、60年代的美国被当做避孕方式，认为这种饮料的酸性可以杀死精虫。

I' enough sperms to knock you up.

ve我的精虫充足绝对搞大你肚子。

Anderson of Boston University School of Medicine and Harvard Medical School, for discovering that Coca-Cola is an effective spermicide, and to Chuang-Ye Hong of Taipei Medical University, C.C.

化学奖：美国科学家提出可口可乐是一种有效的杀精虫剂，但来自台湾的科学家则否定这种论调，结果两组人马同时获奖。

Histologically, the seminiferous tubules contained numerous Sertoli cells and more Sertoli-spermatozoa complexes, accompanied by the depletion of Leydig cells with deeply stained nuclei. Mature spermatozoa were stored up in the epididymis, but only a few in the efferent ducts. In the second place was testicular atrophy（32/120; 26.7%）. The seminiferous tubules showed moderate to severe inactivity of spermiogenesis with evidence of only spermatogonia, spermatocytes and Sertoli cells. The Leydig cells were obviously decreased in numbers associated with decrease of lipid droplets in their cytoplasms. Testicular hypoplasia was the third disorders（22/120; 18.3%）. Only a few spermatogonia and Sertoli cells appeared without any spermiogenesis. The associated changes was decreased in Leydig cells and fibrous hyperplasia in the interstitium.Epididymal stones were sometimes found（12/120; 10%）. Grossly, yellowish-white nodules with various sizes and firm in consistency were observed in the epididymis and the front efferent ducts. Microscopically, the epididymal ducts were dilated with voluminous spermatozoa storage, even showed calcification in severe cases. The deposited calcium salts were stained positively by Von Kossa and Alizarin red methods.Amyloidosis was also detected in 10 roosters（8.3%）. Eosinophilic, homogeneous, amyloid-like substances were deposited mainly in the testicular interstitium and the periphery of blood vessels. These substances showed positive reaction by Congo red staining. Five roosters（4.2%）had Marek's lesions in the testis, epididymis and peripheral nerves with infiltration of pleomorphic lymphocytes. Only one case showed epithelial necrosis of seminiferous tubules accompanied by fibrous proliferation in the interstitium.

结果发现，在总共搜集的120个病例中，其中因年老所导致的产精力不佳为最多，占38例（31.7%），於镜下可见大量精虫黏附於Sertoli cell的表面，并可见Sertoli cell数量明显增多而Leydig cell明显减少，且其细胞核呈现浓染的现象，而在其副睪中仍可见到成熟精虫蓄留於管腔中，但在其输精管内却只有少量精虫存在；其次为睪丸萎缩，占32例（26.7%），镜下可见中度至重度无造精作用，其生精小管中只见到精母细胞、精原细胞及Sertoli cell存在，但Leydig cell数量明显减少且其细胞质内的脂质也明显减少；睪丸发育不全，占22例（18.3%），於生精小管内只见到精母细胞及少量Sertoli cell存在，不见造精细胞分化，於生精小管间质可见Leydig cell减少并伴随结缔组织增生；副睪结石，占12例（10%），肉眼下可在副睪及输精管前段见到黄白色大小不一的结节，触感坚硬，於镜下可见副睪管扩张并有大量成熟精虫蓄积，严重时可见钙化现象，以Von Kossa及茜素红染色均呈阳性反应；类淀粉沉著症，占10例（8.3%），镜下在睪丸间质及血管周围可见粉红均质样的物质沉积，以刚果红染色成阳性反应；马立克病，占5例（4.2%），镜下可在睪丸、副睪实质及周边神经内均可见到嗜碱性大小不一的淋巴样细胞浸润；睪丸坏死，占1例（0.8%），镜下可见生精小管上皮细胞坏死脱落及间质结缔组织增生。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
