摘　　要：目的构建一个简单、经济的新的甲真菌病体外模型。方法制备猪甲板,在其腹侧面中央黏贴一个"O"型圈,将受试菌液加入"O"型圈内,将甲板放置培养皿中培养,用大体观察及组织病理的方法动态观察不同真菌侵袭甲板的情况。结果用猪甲板制备甲真菌病体外模型,通过该模型观察了红色毛癣菌、须癣毛癣菌以及白念珠菌穿透甲板的能力。通过组织病理学方法观察到了真菌动态穿透甲板的过程。结论该模型适用于评估真菌对甲板的致病作用。Objective To determine a simple,novel and economic in vitro onychomycosis model.Method An innovatively designed ＂0＂ ring was applied to localize the fugal suspension on the ventral surface of the porcine hoof,then 50 μL of fungal suspension was applied.The hoof membranes were cultured in sterile petri dishes.The dynamic penetration of hoof plates was observed with gross appreance and histopathological examination.Result In this study we developed a novel in vitro model of onychomycosis with porcine hoof in which we observed the Trichophyton rubrum,Trichophyton mentagrophytes and Candida albicans dynamic permeation to the dorsal of porcine hoof both by gross appreance and histopathological examination and this model also enables one to evaluate how the fungi behave in the nail plate and changes in the localization.Conclusion The model facilitates monitoring of the nail pathogenicity.
