However, the study indicated that the fecundation ability was decreased no matter what cryoprotective mediums and what freezing methods were used, companied with the losing of proteins, changing of proteins expressing quantity and increasing or decreasing of the function and activity in sperm after cryopreservation. Now, the study is altering to exploit the essence of the change of protein structure and function, and elucidate the cryodamage mechanism of sperm cryopreservation, which may provide the basic theory for cryopreservation of boar semen and promote the rapid development of the technique of boar semen cryopreservation.

但研究表明，无论采用何种冷冻保护剂、何种冷冻方法都损害了精子的受精能力，并伴随有蛋白质的丢失、表达量的改变、功能活性的增减等，这种研究现状迫使该领域的研究向充分揭示冷冻对精子损伤的机理方向转移，希望通过揭示冷冻保存所导致的蛋白质结构和功能改变的实质，充分阐明冷冻损伤的机理，为猪精液冷冻保存提供理论依据，并最终促进猪精液冷冻保存技术的快速发展。

Diploid gynogenesis was induced by activating egg development with UV irradiated sperm (80 mJ/cm2, the homologous or the heterogenous sperm) for 5 min in seawater at 18 ℃, and then subjecting the eggs to cold shock in 3 ℃ seawater for 45 min.

无论同源精子还是异源精子，最佳诱导条件为在18 ℃条件下，精子经80 mJ/cm2的紫外线照射，受精后4~5 min将受精卵放在3 ℃海水中进行冷休克处理，持续时间为45 min，同源精子和异源精子二倍体诱导分别为32.66%±7.03%和28.00%±6.48%。

Results indicated that, just like the homologous sperm of summer flounder, the cryopreservative sperm of Lateolabrax japonicas could induce diploid gynogenesis of summer flounder.

实验表明：犬齿牙鲆同源精子经80 mJ/cm2 的紫外线照射可以完全失活，冻存花鲈精子经紫外线照射后也同样具有诱导犬齿牙鲆雌核发育的能力。

The level of tPA before and after treatment was not significantly different .Me made the conclusion that tPA had no effect on sperm\' growth , migration and maturation .However we found that the level of uPA in seminal plasma of health adult and patient had statistics difference(P.01). The health adult\'s level of uPA in seminal plasm was higher than patient\'. The level of uPA was improved after treatment and has statistics difference(P 0.01). The incrementation of upa had linear correlation with incrementation of sperm motility of

根据实验研究结果，再结合上述的病机假说，我们认为本实验证明了少、弱精性不育患者精浆中出现了"精瘀"的中医微观证，"精瘀"为其主要的病理变化；在病机演化中，肾虚是不育疾病之本，血瘀是肾虚的继发病理产物，血瘀日久会导致肾虚；并对肾虚-血瘀-不育三者关系作了理论探讨，对聚精汤的(来源：A5a2a2aBC论文网www.abclunwen.com)组成药物进行了本草析微、方义剖析，得出补肾活血法治疗此疾病不但有理论基础，也有实验依据，补肾活血法是治疗这类疾病的有效法则；还提出可以把uPA看作"精瘀"的实验指标，这对男性不育的病因分析、疗效观察、预后判断有一定的来源：A7676BC论文网www.abclunwen.com

This kind of structure of micropyle has been proved by computer simulation to be favourable for the sperm to agglutinate and enter the micropyle. So, another kind of teleost is found after Misgurnus anguilicaudatus, in which exist unnegligible mechanical dynamic factors besides the chemical one during the sperm entry into the micropyle.
