摘要: 目的 比较2种神经髓鞘染色方法在Cuprizone小鼠模型脑组织中脱髓鞘的形态学变化,为实验诊断提供病理依据。方法 将Cuprizone掺入饲料中喂食小鼠4周,造成神经脱髓鞘模型。取脑后切片,分别用牢固蓝(Luxol Fast Blue)和油红O两种染色方法观察脑纹状体和海马两个切面胼胝体髓鞘脱失变化。结果 牢固蓝和油红O两种染色方法均可显示Cuprizone模型小鼠脑内胼胝体部位有脱髓鞘发生,但在纹状体切面油红O染色法能清晰显示髓鞘脱失和炎性细胞浸润,而牢固蓝染色法显示髓鞘脱失与周围组织结构界限不明显。结论 与牢固蓝染色法相比,油红O染色法能更清晰显示脱髓鞘,颜色对比明显,是一种简单易行的神经髓鞘染色方法。

Abstract: Objective To compare two methods of myelin staining for detecting the morphological changes in the brain of Cuprizone-induced demyelination model mice. Methods Demyelination model was induced by Cuprizone which was mixed in forage and fed to mice for 4 weeks. After the brain tissue sections were made, Luxol Fast Blue(LFB) and oil red O staining methods were used to observe demyelinative changes in the corpus callosum on striatum and hippocampus sections. Results The results from both LFB and oil red O staining showed that demyelination occurred in the corpus callosum of Cuprizone-induced model mice, but the morphological changes in the striatum section were clearer detected by oil red O staining than that measured by LFB staining, and the margin of demyelination with the surrounding tissue was not clear on the section stained by LFB. Conclusion Compared with the LFB staining, Oil red O staining showed clearer demyelination and is a simple myelin staining method.
