卵母细胞

Objective: To investigate the parthenogenetic activation of calcium ionophore A23187 and puromyein on the human oocytes matured in vitro.

目的：探讨钙离子载体A23187或联合嘌呤霉素对人类体外成熟卵母细胞的孤雌激活作用。

Parthenogenetic activation of oocytes was important technology of embyos production in vitro.

目的 卵母细胞孤雌激活是胚胎体外生产一项重要技术。

Parthenogenetic activation of oocytes was important technology of embyos production in vitro.

The effect of EGF on the maturation of oocyte nuclear and cytoplasm is studied by adding EGF in culture media in vitro. In addition, it is also examined by parthenogenetic activation.

本试验在体外成熟培养液中添加EGF，研究其对核及质成熟的作用，并通过孤雌激活来检验EGF对牛卵母细胞胞质的成熟。

The perivitelline space was narrow at GV stage and there were many microvillus penetrating zona pellucida between oocyte and cumulus cells.

在减数分裂启动过程中，小鼠卵母细胞内也发生相应的形态学上的变化。

After treatment in M2〓 medium containing 3% sucrose, a swelling around the metaphase chromosomes could be easily found in perivitelline space and, moreover, the area of spindle, becoming transparent and taking a shape of"∞"and"O", could be well distinguished from other cytoplast.

在本研究中，采用含3％蔗糖的M2〓操作液（3SCOM）处理卵母细胞，可使纺缍体部分变为透明并呈&〓&或&O&形状，这样可使其明显区别于周围的细胞质。

We compared the effects of ICSI with and without a combination of DTT and EA on male pronuclear formation and embryonic development of porcine oocytes.

比较DTT与电激活的联合处理或单一处理对ICSI后猪卵母细胞雄原核形成与胚发育的影响。

Icrofilaments were mainly distributed in the cortex area which chromosomes located at mataphase of second meiosisand concentrated around pronuclei after pronuclear formation.

II 期卵母细胞微丝主要集中在染色体所在的皮层区域，原核形成后微丝绕核重新聚集。

A large number of life-events perceived as having a negative impact on quality of life may indicate chronic stress, and the results of our study indicate that stress may reduce the chances of a successful outcome following IVF, possibly through psychobiological mechanisms affecting medical end-points such as oocyte retrieval outcome.

大量的生命活动视为具有负面影响的生活质量可能表明慢性应激，和我们的研究结果表明，压力可能会减少成功的机会结果如下体外受精，可能通过影响医疗psychobiological机制终点如卵母细胞检索结果。

The artesia exited on different phases.The artesia of primordial follicle and secondary was simple,and the follicle show dedifferentiation,and nucleolus become pycnotic and anamorphic.

卵泡闭锁发生于卵泡生长的各个时期：原始卵泡和次级卵泡闭锁较简单，为卵母细胞首先表现出退行性变化、皱缩；卵泡细胞核固缩、卵泡变形。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
