Phase Contrast and Differential Interference Contrast Microscopy

14.8K
Phase-Contrast Microscopes
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...

科学领域:

  • 生殖医学 生殖医学
  • 显微镜技术 显微镜技术
  • 不孕症诊断 不孕症诊断 不孕症诊断

背景情况:

  • 内细胞质精子注射 (ICSI) 是一种关键的辅助生殖技术.
  • 精子选择对于ICSI成功至关重要.
  • 目前的精子选择方法在评估精子形态方面存在局限性.

研究的目的:

  • 评估在ICSI中使用定量相显微镜 (QPM) 进行精子选择的临床结果.
  • 为了比较QPM辅助的ICSI与传统的ICSI和细胞体内形态选择精子注射 (IMSI).

主要方法:

  • 三组的前性比较:QPM辅助的ICSI,传统的ICSI (同一个患者) 和历史的传统ICSI.
  • 通过QPM辅助的ICSI和IMSI周期之间的比较.
  • 包括1243个总周期.

主要成果:

  • 与标准ICSI相比,QPM组的怀孕和分娩率显着更高 (分别为56.2%与18.1%和50%与9%).
  • 与IMSI组相比,QPM组的怀孕和分娩率也明显高于IMSI组 (分别为56.2%与16.6%和50%与16.6%).
