甲真菌病的实验诊断研究

Study on laboratory tests for the diagnosis of onychomycosis

为寻找一种准确的甲真菌病的实验诊断方法，对５４例拟诊为甲真菌病的病甲分别采用直接镜检、真菌培养、组织病理学方法进行对比研究，同时取６例病甲进行扫描电镜观察。结果显示用３种方法检查甲真菌的阳性率分别为７２．７７％、７０．３７％、８７．０４％。电镜扫描６例均阳性，与光镜所见相符。故认为组织病理学方法阳性率高，是一种有用的辅助诊断的方法。

In order to find useful laboratory tests for the diagnosis of onychomycosis, we applied direct microscopy, culture and histopathological method to examine infected nails, and six specimens were randomly taken and observed under scanning electron microscopy. The positive rates of three methods were 72.77%, 70.37%. 87.04%, respectively. Six specimens were all positive under scanning electron microscopy, and was consistent with that of light microscopy. In conclusion, histopathological method can be used as an adjuvant for the diagnosis of onychomycosis.
