EFFECT IN ACROSOME REACTION AND FERTILIZATION ABILITY OF SPERM WITH ULTRAVIOLET IRRADIATION

紫外线辐射对精子顶体反应和受精能力的影响

The morphology and acrosome reaction of sperm may be two important parameters to evaluate the function of fertilization.

因此，精子形态分析和顶体反应二项参数，在自然周期和IVF周期中，对受精功能的评价有着不同的参考价值和意义；同时，在人类辅助生殖技术实施过程中可以作为选择不同辅助生殖技术的依据。

Prior to fertilization sperm has to undergo an activation process known as capaciation, leading to the acrosome reaction.

在受精之前精子必须完成一个被称为"获能"的活化过程，最终发生顶体反应。

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 cytoplasmic region is posterior to the acrosome and consists of lamellar complex.

退化的细胞质分布于核杯和顶体之间，内有膜复合体。

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。

On the top of each nucleus lay a Golgi body-mitochondria area which later developed into an acrosome.

核的顶部出现一个高尔基-线粒体区，顶体由高尔基液泡演变而成。

By using the chlortetracycline assay, we found the effect of GABA on rat spermatozoa acrosome reaction is biphasic, i.

本研究则进一步分析这两种受体在大鼠精子顶体反应中的作用机制和相互关系。

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。

Fertilization is a complicated biological process, during which spermatozoa must undergo proper changes in their structure and function to finish capacitation and acrosome reaction.

受精是一个复杂的生物学过程。在这一过程中精子首先必须经过复杂的结构和功能改变，完成获能和顶体反应。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
