精子的

Methods: The sperm morphology and sperm acrosin activity were analyzed by automated sperm morphology analyzer and spectrocolorimetry.

精子形态和顶体酶活性是决定精子能否受精的重要因素[1，2 ] 。

Bcl-2 protein was expressed in all kinds of germ cells, of which the highest expression rate was seen in spermatids and spermatozoa.

Bcl-2蛋白在各级生精细胞中均有表达，在精子细胞和精子中的表达率最高。

Spermatozoal SOD activity was positively correlated to sperm motility, normal morphology and sperm swelling by sperm hypo-osmotic...

提示精子SOD活性与精子结构、功能有关，可作为衡量精液质量的一个新指标。

Methods A series of semen parameters and functions of sperm from different parts of 10 epididymides from normal male were observed and investigated.

将附睾切断分成附睾头、附睾尾和附睾体，分别纵向剖开，置于含有 10 %小牛血清的F10 溶液中，37℃孵育 30min ，孵育液作精子常规分析、低渗肿胀试验、精子-宫颈粘液穿透试验。

Some handles may turn off genes in sperm and egg cells . The genes then remain shut off after a sperm fertilizes an egg .

一些处理可能关闭精子和卵子的基因，这些基因在精子使卵子受精后一直处于关闭状态。

Strong expression of nanos 1 mRNA was detected in spermatogonia and relatively weaker signal was found in primary spermatocytes but no nanos 1 mRNA expression was observed in spermatids. The results suggested that nanos 1 may play an important role in maintenance and functioning of the germline stem cell—oogonia and spermatogonia.

在斑马鱼精子发生中， nanos1 mRNA可在精原细胞和初级精母细胞中检测到。nanos1 mRNA的阳性信号在精原细胞中极为强烈，在初级精母细胞中较为微弱，而精子细胞中没有阳性信号。

When sperms and eggs are formed, only one of each chromosome pair enters the sperm or egg.

当精子和卵子的形成，其中只有一个，每个染色体配对进入精子或卵子。

The expression was observed in round spermatids with a gradual decline in the process of metamorphosis of the spermatids, but not in elongated spermatids and sperms.

在伸长的精子细胞和精子中未检测出cyclin B1 mRNA。

One main functionality of men is to produce semens, but we already have banks for that nowadays.

男人的主要功能时产生精子----但我们现在有了精子银行。

The prewashed samples and postwashed samples were analyzed by seminal fluid assay.RESULTS:(1) The positive rate of semen HBV DNA was 21.05%(12/57) with 4.7810~4copies/ml on average; the positive rate of serum HBV DNA was 81.82%(45/55 with 2.3310~7copies/ml on average. There is positive rank correlation between semen HBV DNA copies and serum HBV DNA copies;(2 There were 7 positive cases in 21 samples before washing, the 6 cases except one were positive after washing;(3) there arepositive rank correlation between viability、round cells、 abnormal morphology and semen HBV DNA copies.

结果：（1）精液HBV DNA阳性检出率为21.05%（12/57例），平均拷贝数为4.7810~4/ml，血清HBV DNA阳性检出率为81.82%（45/55例），平均拷贝数为2.33(10~7/ml，精液与血清HBV DNA拷贝数等级间存在正相关关系；（2）21份用于洗涤的精液标本中，7份精液HBV DNA阳性，阳性率为33.33%（7/21例），洗涤后仍有6份标本阳性；（3）精液常规分析显示精子活力、圆细胞数、精子畸形率与精液中HBV DNA载量之间存在正相关关系。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
