概括
马的卵泡液中铁的含量与血相似,但转素的含量更高,表明本地生产. 毛囊发育不会改变铁的状态,这表明它在马卵巢功能中的作用.
科学领域:
- 生殖生物学 生殖生物学
- 动物科学动物科学
- 生物化学 生化学
背景情况:
- 卵泡液 (FF) 中的铁 (Fe) 状态与女性的生殖事件有关,包括卵泡发育和卵细胞成熟.
- 控制卵泡内铁动态的机制在很大程度上是未知的.
研究的目的:
- 为了确定和比较骑行马的铁 (Fe),费里丁 (Ferr) 和转激素 (TRF) 的毛囊内和血度.
- 调查毛囊发育与马铁状况之间的关系.
主要方法:
- 从30只临床正常的母马收集了60个卵巢.
- 毛囊被分为小 (20-30毫米),中等 (31-40毫米) 和大 (≥41毫米).
- 通过光谱光度测量在FF和血中确定Fe,Ferr和TRF度.
主要成果:
- 毛囊内Fe和Ferr度与血水平相似.
- 与血相比,FF中的转激素 (TRF) 度显著高于血 (p < 0.05).
- 毛囊发育没有改变马的铁状况.
结论:
- 在FF中较高的TRF表明局部de novo来源而不是超过.
- 这些发现为毛囊铁在马正常卵巢功能中的作用提供了新的见解.

Ovarian Cycle
1.0K
The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle...

Hormonal Control of the Ovarian Cycle
406
The ovarian cycle is meticulously regulated by the hypothalamic-pituitary-gonadal axis. This cycle orchestrates the release of a mature oocyte, essential for reproduction.
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...
