概括
丰富血小板血 (PRP) 衍生的外体在冷保存后显著改善精子质量. 在冷前将精子与外生体进行化,可以增强精子的运动性,并减少氧化应激和DNA损伤,在患有阿斯诺特子精子症的男性中.
科学领域:
- 生殖生物学 生殖生物学
- 细胞生物学 细胞生物学
- 生物技术是生物技术.
背景情况:
- 精子冷保存对于保持生育能力至关重要,但可能会损害精子质量.
- 亚氏和精子,其特点是精子的运动性和形态不佳,这对成功的冷保存提出了挑战.
- 丰富血小板血 (PRP) 和其衍生的外体被探索,以发现它们减轻冷损伤的潜力.
研究的目的:
- 评估丰富血小板血 (PRP) 和PRP衍生的外体在改善精子冷保存结果方面的疗效.
- 为了评估PRP和外体对精子参数和氧化应激的影响,在男性与asthenoteratozoospermia.
主要方法:
- 来自75名患有质精的男性的精液样本被分为五组:对照组,冷前添加的PRP/外体,解后添加的PRP/外体.
- 评估了精子参数 (运动性,形态) 和氧化应激标志物.
- 进行了统计分析,以比较各组之间的结果.
主要成果:
- 与对照组相比,在冷1小时前用外体化显著改善了精子运动性.
- 在冷前对外体进行处理,导致DNA碎片化指数 (DFI) 和氧化应激显著降低.
- 虽然PRP治疗显示出一些益处,但外体细胞表现出更强的保护作用.
结论:
- 在冷保存前1小时,用外体化精液化为患有阿斯诺特拉托动物精子症的男性的精子质量提供了显著的保护性益处.
- 外生体有效地减轻氧化应激,并增强冷保存后的精子运动性.
- 这种方法代表了改善生育保护结果的有希望的策略.

02:45Blood Transfusion and Agglutination
Blood transfusion is a therapeutic measure to restore the blood volume after extensive blood loss due to an accident or a medical procedure. Blood transfusion involves drawing a certain amount of blood from a suitable donor and infusing it into the recipient.
History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...

01:26Characteristics and Functions of Blood
Blood is specialized connective tissue comprising about 8% of the body mass. It has a thick, liquid extracellular matrix that contains cells, dissolved proteins, and electrolytes, making it five times more viscous than water. Blood is warm, around 38°C, and has an alkaline pH ranging from 7.35 to 7.45.
The primary function of blood is to transport oxygen and carbon dioxide between tissues and the lungs. Oxygenated blood is bright red, while oxygen-depleted blood is darker. It also carries...
