顶体精子

The rate of morphologically normal sperm and the rate of acrosome intactness were evaluated.

形态正常精子率和顶体完整率是决定精子能否受精的重要因素[1，2]。

The measurement of the ability of sperm to undergo the acrosome reaction is conventionally used for assessment of sperm capacitation.

检测精子是否具有顶体反应的能力是评估精子获能的一种常规方式。

The aim of this study was to determine the relationship between seminal zinc concentration and spermatozoa-zona pellucida binding and the ZP-induced acrosome reaction in subfertile men.

本文旨在研究生育力不足男性的精液中锌浓度与精子-透明带结合和精子透明带诱导的顶体反应间的关系。

Western blot and double staining analyses show NYD-SP27 becomes detached from sperm, as they undergo capacitation and acrosome reaction.

Western blot和双染的研究表明在精子发生获能和顶体反应的过程中NYD-SP27逐渐从精子上丢失。

Objective To investigate the relationship between ovum fertilization rate and sperm morphology, acrosome reaction in IVF and to explore the influence of parameters of sperm on fertilization rate.

目的 研究体外受精(in vitro fertilization，IVF)中精子形态、顶体反应与卵子受精率之间的关系，分析精子各参数在IVF受精率方面的参考意义。

Spermatozoa of Hemicentrotus pulcherrimus belong to the type of flagelloform, it has a coniform cell nucleus on its head, a small apical body on its forepart, four mitochondria, a couple of central granules, and a flagellum.

海胆精子与其他无脊椎动物的精子一样，属于鞭毛型，其头部包含一个圆锥形的细胞核，前端配有一个小的顶体，还包括4个线粒体、一对中心粒和一根鞭毛。

PH-20 is a traditional sperm membrane antigen,and it is a glycophosphatidylinositolanchored hyaluronidase.

PH-20(posterior head 20)作为传统的精子膜抗原，是由磷脂酰肌醇(glycophosphatidylinositol，GPI)锚定的膜结合型透明质酸酶，最适PH值呈中性，它分布于精子表面浆膜和顶体内膜，是一种透明质酸酶诱导信号转导的受体和识别透明带的受体。

Annexin A1 mainly distributed in nuclei of spermatogonia, acrosomal cap of spermatid and residual body of sperm.

免疫组织化学显示膜联蛋白A1主要分布于精原细胞核、精子细胞顶体帽及精子胞质残余体内。

Methods The activity of human sperm acrosin,PMN-Elastase,Fruc-tose,α-glucosidase,Zinc,Acid phosphatase and HOS in214cases were tested determined.The spermwas analyzed by using WLJY-9000WeiLi colorful spermic mass device.

对214例精液标本作精子顶体酶活性、弹性硬蛋白酶、果糖、α-葡萄糖苷酶、锌、酸性磷酸酶、精子尾部低渗肿胀试验检测，同时用WLJY-9000伟力彩色精子质量检测仪作精液分析。

Progesterone and #gamma#-aminobutyric acid could initiate the acrosome reaction in guinea pig spermatozoa,which was independent of extracellular Cl一in vdro,and a potentiation effect between progesterone and GABA was demonstrated.

在体外，孕酮和#gamma#-氨基丁酸可明显地引起豚鼠精子顶体反应，并且两者合并使用，对顶体反应的诱发有协同作用；这种反应不依赖于细胞外C1-。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
