摘要(Abstract):
[目的]探讨多种特殊染色技术在骨关节炎关节软骨组织形态学研究中的染色规律及应用中的优缺点。[方法]15个月龄健康C57BL/6J小鼠20只,随机分为正常组和骨关节炎模型组各10只,骨关节炎模型组行单侧膝关节前交叉韧带横断加内侧半月板切除术建立骨关节炎模型,正常组仅切开单侧滑膜囊行假手术,3个月后膝关节取材。对标本固定、脱钙后进行石蜡包埋、切片。分别采用HE染色、番红O-固绿双染色、Masson染色、Van Gieson染色、苦味酸天狼星红染色、SA-β-gal半乳糖苷酶衰老染色和II型胶原免疫组化染色,观察骨关节炎关节软骨组织形态学变化,并对几种染色方法进行比较。[结果]HE染色可以显示骨关节炎关节软骨的一般形态结构,可见模型组出现退行性变化;番红O-固绿双染色和Masson染色在显示结构方面的优势优于HE染色,模型组退变更明显;Masson染色、Van Gieson染色、苦味酸天狼星红染色和II型胶原免疫组化染色可定位II型胶原,模型组显示II型胶原含量减少;SA-β-gal半乳糖苷酶衰老染色可见模型组衰老细胞增多。[结论]在骨关节炎关节软骨的形态学研究中,番红O-固绿双染色和Masson染色有利于获得全面的信息,II型胶原免疫组化染色有利于对II型胶原进行定位定量;SA-β-gal半乳糖苷酶衰老染色有利于分析细胞衰老情况。
