Examples
- At the stage of late vitellogenic oocyte , follicle cells begin to fade and disappear , and cortical layer and egg membrane come into being
到卵黄形成期后期，滤泡细胞开始由内向外萎缩退化，卵细胞形成皮层和卵膜。 - 4 . mature egg mature egg is composed of egg membrane , egg plasmic membrane , oo [ lasm and nucleus . egg membrane is an electron - densed strap - shaped structyre close to plasmic membrane , which is 1 . 4 urn thick and there is space between plas
成熟卵细胞由卵膜、卵质膜、卵质、细胞核四部分组成。卵膜为紧靠卵质膜的一条电子致密的带状结构，厚约1 4pm ，与卵质膜间无空隙。 - The egg envelopes are composed of secondary envelope and primary envelope which comprise zona radiatal , zona radiata2 and zona radiata3 , and there are tube radiata and flexural sub - elasticity envelope which is vertical with plasma membrane in every zona radiata
唇(鱼骨)卵膜由初级卵膜和次级卵膜组成，初级卵膜具三层辐射带，带内具弯曲的弹性亚膜和辐射管，次级卵膜胶质状，外具浓密的颗粒。 - About 80s after fertilization , the angle of sub - elasticity envelope expands . 110s , sub - elasticity envelope in zona radiatal becomes parallel with plasma membrane , later , the same phenomenon happen in zona radiata2 and zona radiata3 , which result in the fertilization envelopes ( egg envelopes ) outspreading ; 140min after fertilization , the fertilization envelopes come into being
受精80s ，弹性亚膜弯曲的角度增加， 110s ，第一层辐射带的弹性亚膜拉直， 240s ，第一层和部分第二层辐射带弹性亚膜倾斜，第三层辐射带弹性亚膜拉直，受精膜(卵膜)开始外举， 140min受精膜完全举起。 - 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。
