| 1. | Cortical granule ( cg ) is an unique type organelle of mammalian oocyte . during the maturation of oocyte , cgs shows a specific change in distribution . the generally accepted indicator of final cytoplasmic maturation is the line underneath oocyte membrane constituted by cgs
卵母细胞在成熟和受精过程中，细胞骨架发生一系列明显的变化，微管是一种重要的细胞骨架成分，对于哺乳动物卵母细胞减数分裂的完成、精子的运动、雌雄原核的结合是必不可少的。 | | 2. | 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。 | | 3. | The results were as follows : ( l ) the pre - incubation of pmr induced the exocytosis of the cortical granules ( cgs ) in the oocytes and reduced the quantity of the microvillus on the surface of oocytes ; ( 2 ) the matrix of cg might migrate to the surface of plasma membrane of oocytes after pmr pre - treatment . ( 3 ) incubation of zona - free hamster eggs with spermatozoa pretreated with pmr a ntiserum was associated with a dose - dependent significant reduction in the number of spermatozoa binding to the oolemma , compared with a contraband with a dose - dependent reduction of the fertilization rate and the penetration index . the results indicate that mr of human sperm plays an important role in sperm - oocyte fusion and oocyte activation
结果显示： ( 1 )人精子mr能够诱发去透明带金黄地鼠卵母细胞中皮质颗粒的胞吐，并引起卵母细胞膜表面微绒毛形态和数量发生改变； ( 2 )皮质颗粒胞吐后，其内容物可结合到卵膜表面； ( 3 )抗mr抗血清预处理精子可抑制精子与卵子的结合与融合，使受精率、穿透指数和结合指数下降，并均有剂量依赖性。以上结果提示，人精子mr在受精过程中起重要作用，其主要作用可能是介导精-卵膜融合并促进卵母细胞的活化。 |
