三种显微技术对人毛囊蠕形螨的观察和研究
Sichuan Journal of Zoology(2011)
Abstract
目的采用荧光显微镜、扫描电镜和激光共聚焦显微镜对人体毛囊形蠕形螨进行形态学观察。方法选用5μg/mL碘化丙啶(propidine iodide,PI)对虫体进行荧光染色,避光染色15min,分别置于荧光显微镜和激光共聚焦显微镜下观察;2.5%戊二醛固定虫体标本,梯度酒精和叔丁醇脱水,金喷镀后扫描电镜观察。结果荧光显微镜下碘化丙啶对虫体有很强的结合力,虫体荧光信号均匀展示于细胞表面,充分展现虫体形态,扫描电镜更加清楚、细致地展示人体毛囊型蠕形螨的超微结构,激光共聚焦显微镜将虫体分层扫描图片进行三维重建,真实、完全、直观地展露了虫体。结论三种显微技术均可展示蠕形螨超微形态。PI对虫体有很好的荧光染色作用,使激光扫描共聚焦显微镜能够获得更加精准的超微形态结构,结合三维重建技术有着广泛的应用价值。
