Based on the experience and methods summed up by other researchers, the technique of cell culture was employed to study bovine follicular oocytes maturation, fertilization and the development of earlier embryo in vitro. The objective of this research is to upbuild and perfect a set of high-and-new-tech systems to obtain high-yield and high-quality bovine embryo, to provide technical operational regulations and ways and means to embryo engineering in practical production, to accumulate data for theoretical research.

本研究在总结前人研究的基础上，应用体外培养技术对牛卵母细胞体外成熟、体外受精及早期胚胎体外发育作了进一步研究，旨在建立健全一套完整的体外生产高产优质牛胚胎的高新技术体系，为胚胎工程和生产实践提供技术操作规程和方法，为理论研究积累资料。

The main point is to illustrate the effect of Uracil, ITS, and ATP on bovine oocytes'maturation.

旨在探讨成熟液中添加尿嘧啶和三价因子等试剂对牛卵母细胞成熟的影响。

Objective To explore the feasibility of vitrification of mouse maturation oocytes, using a close-carrier.

目的 探讨封闭式玻璃化冷冻载体冻存小鼠卵母细胞的可行性。

Objective To study the ultrastructural changes of wapiti oocytes and provide theoretical basis for wapiti breeding arid reproduction.

目的 通过对马鹿卵母细胞的超微结构进行研究，旨在为马鹿繁殖育种的研究提供基础理论依据。

Our studies on oocytes ultrastructure, in which experimental materials came from Wapiti, was just one of the blanks.

本研究以马鹿为试验材料，开展了鹿卵母细胞超微结构的研究。

To make the wapiti sperm capacitated in vitro, we selected and used the method of sperm-up. By making the rate of acrosome reaction as a main index, and the sperm energy, the survial time and the fertilizated rate of wapiti sperm and hamster mature oocytes as auxiliary indexes, it were carried out to compare the effects of wapiti sperm capacitation in vitro under different temperature, different density of pyruvate sodium, caffeine and heparin and different culture medium.

对马鹿精子，使用上浮法诱导其获能，通过对顶体染色测定精子的顶体反应率并作为主要指标，同时以精子活力、精子存活时间和异种受精率为辅助指标，对精子的获能效果进行评价，以比较不同培养温度、丙酮酸钠浓度、咖啡因浓度、肝素浓度以及培养基对马鹿精子体外获能效果的影响。

Three types of cells were transferred into perivitelline space under zona pellucida of rabbit oocytes respectively.

用体外培养14代和24代的小鼠胚胎干细胞构建的异种重构卵的卵裂率分别是88.5％和82.1％(P＞0.05)，囊胚发育率分别是16.7％和15.4％(P＞0.05)。

The results indicate that:(1) Using SUZI method can improve the fertilization rates of denuded oocytessignificantly. This result suggests zona pellucida may be one of the reasons that makedenude oocytes matured in vitro have a clearly deficiency on fertilization in vitro.

结果表明：(1)利用精子带下注射技术可以极显著的提高去除卵丘细胞的卵母细胞的受精率，表明透明带结构的改变是去除卵丘细胞的卵母细胞存在受精障碍的重要原因之一。

Result The elasticity modulus of the zona pellucida of these oocytes is (1.43±0.29)×10^4 Pa.

结果］计算得到猪卵母细胞透明带的弹性模量为(1.43±0.29)×10^4Pa。
