1.It suggests that the substances of expressing EPF—like activity in the fertilized ovum culture fluid are highly lipophilic and differ chemically from the EPF in human early pregnancy sera. The expression of EPF—like activity in the mouse fertilized ovum culture fluid is quite possibly due to the high lipophilic substance(like EDPAF) released by mouse fertilized ovum acting on the platelets(or other compositions) and the lalter release EPF.
提示,导致小鼠受精卵培养液中EPF样活性表达的物质是高脂溶性的,在化学本质上不同于人早孕血清中的EPF,由受精卵释放的某种高脂溶性物质(可能是胚源性血小板活化因子EDPAF)作用于血小板(或其它成分),使之释放出EPF。
2.Moreover negative ions of oxygen is supplied in the surroundings during the larva and ovum period,which makes practicaly hatched rate are higher percent 11 38(silkworm) and 9 08(eri silkworm),however,negative ions of oxygen is completed only during the ovum period,which can effectively enhance those and gain the same effect,compared to the silkworm period.
另外 ,幼虫期和卵期环境中都补充O- 2 ,可使实用孵化率极显著地高于对照 11 38个百分点 (家蚕 )和 9 0 8个百分点 (蓖麻蚕 ) ,而只在卵期补充负氧离子 ,也可有效地促进胚子发育与孵化齐一 ,获得与整个蚕期补充O- 2 相近效果。
3.The way it works is first you take out a cell from either a part of the body or a fertilized egg. Then you take that cell and put it in to a unfertilized ovum.
这种方法的过程是首先从身体部分或受精卵中取出一个细胞，然后把它放到未受精的卵细胞中。
4.One way is taking the cell from a fertilized ovum.
一种方法是从受精卵中取出细胞。
5.(of twins) derived from a single egg or ovum.
（指双胞胎）源于同一个卵或者卵子。
6.The spherical embryonic mass of blastomeres formed before the blastula and resulting from cleavage of the fertilized ovum.
桑椹胚形成于囊胚之前且处于胚胎期内的球形裂球群，由受精卵细胞的分裂而成
7.The entity formed by the union of the male sperm and the female ovum; an embryo or a zygote.
合子精子与卵子结合成的物体；胚胎或合子
8.To fertilize(an ovum, for example).
使（例如卵细胞）受精
9.A genetic defect in a child, like lameness or blindness, he said, was not due to any defect in the mother or the father, but in the ovum or sperm of the parents which is today an accepted fact.
他说，一个孩子身上的遗传缺点，例如是跛足，或者是失明，并不是归因于母亲或父亲的任何过失，而是双亲的卵子或精液中今天所接受的真相。
10.fertilization of a second ovum after a pregnancy has begun; results in two fetuses of different ages in the uterus at the same time.
不同排卵期排出的两个或多个卵连续受精；结果是同一子宫内存在有不同龄的胚胎。
