| 4. | These imply the bsp proteins have important functions in sperm lipid metabolism , sperm capacitation and acrosome reaction
目前在猪及马的精浆中也都发现了与bsp蛋白同源的蛋白质的存在。 |
| 5. | The location of the center tubule in the two species is different . in p . trituberculatus it locates at the top of the acrosome tubule , and in s . chekiangenser it locates at the base
脊尾白虾边缘不翻卷，核为泡状核和丝状核，棘突由具等距横纹的纤丝组成，较长。 |
| 6. | There are two forms of nucleus in the e . carinicanda sperm : fibrous and vesicular ones the sperm ultrastructures of the p . trituberculatus and s . chekiangense consist of nucleus cup , radial arm , acrosome
2 .精子结构罗氏沼虾与脊尾白虾的精子结构相近，呈图钉状，由棘突、顶帽和精核组成。 |
| 7. | The head of spermatozoa contains a nucleus but no acrosome . the nuclear fossa developes well . during the process of spermtogenesis , within the nucleus the chromatin condenses step by step into wads , among which are loose chromatin fibers
成熟精子头部无顶体，主要为核占据，精子形成过程中，细胞核中的染色质浓缩成致密的团块状，团块状的染色质之间分布着松散的纤维状染色质。 |
| 8. | Northern analysis revealed that p3galt - l was exclusively expressed in the brain while that p4galt - l was expressed highly in testis , moreover , sperm surface p4galt - l was suggested to play a significant role in signal transduction involving the acrosome reaction in the mouse . in the present study , we mainly detected the developmental expression and function of p - galactosyltransferases in mouse brain and testis . we first characterized the developmental expression of 3galt - l in mouse brain
- 1 ， 3 -半乳糖基转移酶- 1 ( 3galt - 1 )主要在脑中表达，而- 1 ， 4 -半乳糖基转移酶- 1在睾丸中表达较高，且精子细胞表面的- 1 ， 4 -半乳糖基转移酶- 1在精卵结合后的顶体反应中发挥了重要的生理作用。 |
| 9. | Nucleoli do not emerge in this process . the number of the organelles increase until secondary spermatocyte stage . mitochondria accumulate together , merging together with lysosomes and golgi bodies at the early spermatid stage , and finally the lamellar structure is formed , which forms the acrosome at last
在精子发生过程中，线粒体、内质网和核糖体逐渐增多，其中线粒体数目在次级精母细胞阶段达到顶峰，并形成线粒体区，精细胞早期核内出现膜性泡结构，同时次级溶酶体与高尔基体大量存在，这些细胞器共同形成片层复合体，并参与顶体的形成。 |
| 10. | In order to investigate the role of mannose receptor ( mr ) of human sperm , the zona free hamster eggs were pre - incubated with purified mr ( pmr ) isolated from motile human sperm by mannose - agarose gel affinity chromatography . the ultrastuctural alteration and cortical granule exocytosis of the eggs were then observed by transmissian electron microscope and tritc - lca immunofluorescence microscope , respectively . the mice were immunized with pmr and the antiserum was raised . after capacitation and induction of the acrosome reaction , the human spermatozoa and oocytes were incubated with the antiserum . then the sperm penetration assay was undertaken
为了进一步探讨人精于mr在精卵融合中的作用，本文采用改良后的甘露糖-琼脂糖凝胶亲和层析法分离纯化人精子mr ，并将提纯的人精子甘露糖受体( purifiedmannosereceptor , pmr )作用于去透明带的金黄地鼠卵母细胞，运用透射电子显微镜技术和罗丹明偶联的兵豆凝集素( tritc - lca )免疫荧光标记技术观察pmr对卵子的影响。 |
