查询词典 sperm

The pupae were exposed to 9 krad 60Co-γ rays for two days before emergence.The adults were dissected and many mature sperms could be seen in the male flies.There were no significant difference in the form,number and vigor of sperm between irradiatid and unirradiated male flies,but there were some abnormal ultrastructurail changes in the sperm of irradiated male flies such as the appearence of vacuoles in nutrient cells,disarrangement of sperms,variation of the number of chondriosome derivates,axonemes ction of formation and abnormal cell division of sperm cells.

用9krad辐照羽化前2天的蛹，成虫羽化后解剖观察，雄虫已有大量成熟精子，精子形态、数量和活力与未经辐照处理的雄虫无显著差异，但其超微结构则发生了某些异常变化，如营养细胞出现空泡、精子排列零乱、线粒体衍生体和轴丝增多或减少、构型被破坏、精子细胞分裂异常等。

Some sperm with damaged DNA may escape from the sperm surveillance mechanism and transmit the damage to the offspring.So research on the damage to sperm DNA has become one of the hot spots in reproductive medicine.

替代组蛋白成为精核蛋白的鱼精蛋白和大量的二硫键使精子染色体高度压缩，这种特化的结构可以保护精子DNA免受伤害，因此成熟精子对各种致病因素有较强的抵抗力。

By using two color FISH with one euchromosome probe and one sex chromosome probe, the sperm with same color of two hybridization signals in one sperm head could be identified as aneuploidy sperm or diploid sperm.

若用1条常染色体探针和1条性染色体探针进行FISH，可以区别头部有2个相同颜色荧光杂交信号的精子属非整倍体精子或二倍体精子。

We have done some studies to look at the quantity and quality of the sperm, and intersex bass did have somewhat lower sperm count as well as less motor sperm, she says.

我们已经做了一些研究，看看精子数量和质量，雌雄同体低音也有所降低精子数量减少以及精子运动，她说。

It is satisfactory to lyse sperm with sample preparation Method Ⅰ and to separate sperm proteins by IPG-DALT for establishing 2-D map of human sperm.

采用蛋白质提取方法一制备精子蛋白质进行IPG-DALT电泳的方法适用于建立精子全细胞蛋白质谱。

Result: In the same conditions, all the small, medium and large extracts of M. officinalis （0.125, 0.25, 0.5 g·mL-1）improved SOD vitality of sperm suspension, reduced the content of MDA, intervened in the injury of sperm membrane by ROS to some extent and protected some function of sperm membrane.

结果：巴戟天水提物小、中、大剂量组（0.125，0.25，0.5 g·mL-1）在相同的条件下均可提高精子悬液SOD活力，降低MDA含量，对ROS所致精子膜的氧化损伤均具有不同程度的干预作用，对精子膜功能具有一定的保护作用。

The sperm treated with trypsin, plasmin, pepsin and succinic acid sodium respectively, only trypsin can dissociate the eupyrene sperm bundles and improve the motility of apyrene sperm synchronously, and olso only the trypsin-treated sperm have the ability of fertilization.

用胰蛋白酶、血纤维蛋白溶酶、胃蛋白酶及琥珀酸钠处理精液，仅胰蛋白酶能够在很好的溶解有核精子束的同时提高无核精子的运动性，也只有胰蛋白酶处理的精液人工授精能够得到受精卵。

Cervical mucus, semen consistency pilot test of time in the prediction of ovulation election period, a drop of glass on the first and fresh semen, cervical mucus and then take a drop of semen on the next, distance 2,3 mm, not to coverslip pressure to hand light light rock slide, so that two drops of liquid close to each other, under the microscope to observe sperm penetration capacity, such as the sperm can move through the mucus and to continue to run that sperm motility and cervical mucus of the characters are normal, mucus-free anti - sperm antibodies.

宫颈粘液、精液相合试验试验时间选在预测的排卵期，在玻璃片上先放一滴新鲜精液，然后取子宫颈粘液一滴放在精液的旁边，距离2、3mm，不要盖玻片加压，以手轻轻摇动玻片，使两滴液体互相接近，在显微镜下观察精子的穿透能力，如精子能穿过粘液并继续向前运行，表示精子活动力及宫颈粘液的性状都正常，粘液中无抗精子抗体。

And MIS is also found to bind to specific receptor on the membrane of sperm. Our study showed that viability of fresh human sperm incubated with His6-tagged rMIS (303-376) was higher than in absence of His6-tagged rMIS (303-376) at 5 and 22 hours, indicating MIS affects the motility and viability of sperm by binding of its 74 amino acids segment with the specific receptor on the sperm membrane, most probably YWK-Ⅱprotein.

在我们的实验中，将His〓-tagged rMIS（303-376）与人精子在37℃孵育5和22小时后，分别检查精子的生存情况，发现精子生存力比对照组明显提高，这说明MIS可能是通过其中74个氨基酸片段与精子膜上特异受体结合而对精子发挥作用，而此受体很可能是YWK-Ⅱ蛋白。

Pig oocytes cultured in vitro for some time were inseminated by frozen–thawed ejaculated sperm. At specified times after insemination, sperm penetration, cell cycle progression and mitogen-activated protein kinase phosphorylation were evaluated. It was shown that:(1) oocytes at various maturational stages could be penetrated by sperm;(2) sperm penetration did not affect meiotic cell cycle progression;(3) sperm penetration of germinal vesicle oocytes and maturing oocytes did not alter MAPK phosphorylation; and (4) when premetaphase I and metaphase I oocytes, in which MAPK was activated, were fertilised, no evident MAPK dephosphorylation was detected as in metaphase II oocytes.

不同成熟阶段的猪卵与精子融合后体外培养发现：(1)不同成熟阶段的猪卵母细胞都可被精子穿透；(2)精子穿透不影响减数分裂细胞周期进程；(3)精子穿透GV期卵母细胞和正在成熟的卵母细胞不改变MAPK磷酸化：(4)已受精的前中期I和中期I卵母细胞的MAPK有活性，MAPK不像MII卵母细胞那样受精后发生磷酸化。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。
