一种优化的大鼠视网膜组织石蜡切片制作方法
An Improved Method for Preparation of Paraffin Slices of Rat Retina
摘要
Abstract
Objective To solve the problem that the rat retina paraffin sections are easily exfoliated from the slides and each layer are easily separation and fracture,we need to find a way to improve the retina paraffin section method and evaluate the tissue fixation. Methods We used 4 fixation liquids including 10%paraformaldehyde,4%paraformaldehyde, 4% paraformaldehyde and 95% alcohol and glacial acetic acid mixed liquid (FAA fixatiue solution ) combined with paraformaldehyde to fix the retinal tissue, and observed the fixation efficacy under microscope after HE staining. Results The effects of 10%paraformaldehyde and 4%paraformaldehyde fixed samples showed moderate separation and fracture of retina,but the HE staining retinal slices pre-treated by the FAA fixafive solution had bright and uniform color,although occasionally some parts of the retina were exfoliated from the slide, but it was not easy to take off,and had complete structure without separation and rupture. Conclusion The retina paraffin section fixed by FAA ixafive solution with 4% paraformaldehyde is superior to pure paraformaldehyde, and the paraformaldehyde concentration has no obviously influence on HE staining results.关键词
