卵泡

FSH is one of the most important endocrine factors in regulating follicular development.

卵泡刺激素是调节卵泡发育重要的内分泌激素，同时许多卵巢内局部产生的生长因子对卵泡发育也有重要的调节作用。

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 level of oestradiol (E2) arrived the highest value (48.24pg/mL) in the sixth day of culture for follicles with a diameter of 100m above in the 10% BFF group.

表明培养液中添加一定比例牛卵泡液可显著刺激体外培养腔前卵泡E2的分泌，促性腺激素存在下更加强了卵泡液对E2分泌的刺激作用。

Do not cause decomposition of one ovulation, mature follicles to a certain stage, clearly highlighted in the ovarian surface, with the proliferation of follicular fluid, internal pressure increases, so that more and more prominent part of the ovarian tissue is thin, the final rupture secondary oocyte cells and their peripheral zona pellucida and corona radiata, together with the discharge of ovarian follicular fluid in the process called ovulation.

不排卵原因分解1、成熟卵泡发育到一定阶段，明显地突出于卵巢表面，随着卵泡液的激增，内压的升高，使突出部分的卵巢组织愈来愈薄，最后破裂次级卵母细胞及其外周的透明带和放射冠随卵泡液一起排出卵巢这一过程称排卵。

The arise of Ang II was found in thecal cells specially, the reason could be due to an abundance of blood vessels in the thecal cell layer, but not in the granulosa layer. E2, P, T may play very important roles in the follicle development and atresia.

RAS的变化主要发生在卵泡膜细胞，可能与卵泡膜细胞层具有丰富的血管而颗粒细胞层中无血管有关。E2、P、T具有不同程度的促进卵泡发育和抑制闭锁的作用。

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。

Results: The Ang II levels increased significantly in the atresia follicles, either in follicular fluid or in the medium of cultured thecal cells. At the same time the renin activity levels decreased markedly. No significant change in the levels of both Ang II and renin activity was found in the medium of cultured granulosa cells.

结果：卵泡在闭锁状态下的Agn II水平在卵泡液中以及卵泡膜细胞培养液中均显著升高，肾素活性水平明显下降；颗粒细胞培养液中两项指标均无明显改变。

The clue is the prominent eosinophilic and hyalinized so-called "glassy membrane" band in between dark spindle granulosa layer and lutinized theca interna. There are scattered lutinized thecal cells in theca interna with ample pink cytoplasm which are usually seen in childhood or pregnancy.

诊断线索是明显的嗜酸性胞质和位于暗梭形颗粒细胞层和黄素化卵泡膜之间的透明化的所谓&透明膜&带，在卵泡膜内层有散在黄素化卵泡膜细胞，胞质淡粉染，这种细胞常见于儿童期或孕期。

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。

The result suggested that FSHR only exsited in granulosa cell and cumulus oophorus and was found in all follicle. LHR mainly exsited in granulosa cell and theca interna cell.

研究结果表明：FSHR存在于卵泡细胞和卵丘细胞，从原始卵泡开始FSHR存在于各级卵泡中。

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。
