卵泡的

The phase of artesia was forepart,metaphase and anaphase.

三级卵泡的闭锁分为早期、中期和后期三个时期。4。

This experiment first preliminariely revealed the basic processes of the in vitro development of hircine non-antral follicles.

本试验首次初步揭示了山羊无腔卵泡的体外发育基本过程和规律。

Then in accordance with the development of follicle size, 3 days on the 18th and had a follicle monitoring, size 17 * 14 leucorrhea

然后根据卵泡的发育大小，3天后18号又进行了一次卵泡监测，大小为17*14

Bone morphogenetic protein 15 is only expressed in oocytes. Oocyte-specific BMP-15 might promote follicle growth in vivo, while preventing premature luteinization.

骨形态发生蛋白 15(BMP-15)基因在卵母细胞中特异表达，对卵泡的生长发育起着重要的调节功能，具有推动卵泡生长，阻止黄体早熟的作用。

The follicular fluid was aspirated from both the healthy follicles and the atretic follicles, and all the hormonal levels were measured as well.

收集健康和闭锁卵泡的卵泡液同时进行上述各项指标的测定。

The rates of apoptotic granulosa cells in all kinds of follicles in immature gilts were ashigh as atretic follicles;it decreased significantly after injection of PMSG,but it was higherand lasted shorter than that of mature pig.

性未成熟仔母猪卵巢中各类卵泡颗粒细胞凋亡比例很高，接近闭锁卵泡的凋亡比例；注射PMSG后则各类卵泡颗粒细胞凋亡比例显著下降，但高于性成熟母猪注射PMSG后的凋亡比例，并且维持的时间也较短。

Recruitment, selection and dominance are included in follicular development, but the mechanism of their appearance is not clear.

卵泡的发生包括卵泡的募集、选择和优势化，对子卵泡在发育的过程中出现这3个阶段的机理研究尚不是很清楚。

The productions of E2, P, T decreased in the atresia follicles, either in follicular fluid or in the media of cultured granulosa and thecal cells.

闭锁卵泡的卵泡液、颗粒细胞和卵泡膜细胞培养液中的E2水平均显著下降；P、T水平也有不同程度的降低。

By this the system, bovine preantral follicles in different diameters were cultured in vitro;and the effects of the number of follicles in each well of culture plate, different concentrations of NGF, Vitamin E, and Vitamin C on in vitro development of preantral follicles were studied.

在96孔培养板中，每孔25μl培养液的条件下，利用此系统研究了卵泡的入培直径、共培养卵泡数及神经生长因子、维生素C和维生素E对腔前卵泡体外发育的影响。

Though it was slower in the frozen-thawed embryo transfer group than that of the fresh embryo transfer group, there were no significant differences in estrous cycle between experimental group and normal control group. The grafts were taken out and observed on day 63 after transplantation, rich blood vessels were formed on the cover of the graft, arterioles and venules could be seen under microscope. Histological examination of graft revealed that transplanted fetal ovary contained follicles in different developing stages, vesicula graafianae and corpus luteum were formed, and the morphous of graft was no obvious differences to normal ovaries.

冷冻移植组大鼠恢复动情周期虽稍短于新鲜移植组，但差异并无统计学意义。63 d后取出移植物观察，见移植物色泽红润，表面有丰富的血管形成，镜下见卵巢内有大量的小动脉和小静脉；移植物组织学检查发现卵泡的发育，光镜下可见不同发育阶段的卵泡，有成熟卵泡和黄体形成，形态与正常卵巢无明显差别。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
