TritonX-100诱导嗅觉障碍后小鼠嗅上皮结构和嗅觉功能的改变及两者的相关性
【目的】 用TritonX-100(TX)诱导一种嗅觉障碍模型,观察不同时点嗅上皮的组织学改变和小鼠嗅觉功能的变化,并对两者进行相关性分析?【方法】 用0.7%的TX对8 ~ 10周的BALB/C小鼠灌鼻以诱导小鼠嗅觉障碍,分别于灌鼻后第3?7?21?49?56天行觅食实验,以觅食时间的长短评估小鼠嗅觉功能的改变;用免疫组织化学染色(IHC)的方法,检测小鼠嗅上皮(OE)中成熟嗅神经元(ORN)数量?嗅上皮厚度?嗅上皮细胞总数的变化;并对小鼠觅食时间的改变和嗅上皮中成熟嗅神经元数量的变化行相关性分析? 【结果】 TX诱导小鼠嗅觉障碍后,第3 ~ 7天时,小鼠嗅上皮中成熟ORN的数量急剧下降,嗅...
