英文摘要	本文以氩离子激光为激发光源，以光学多道分析仪（OMAⅢ）为光谱分析手段研究恶性肿瘤的激光荧光谱特征。研究中，不给患者任何药物，直接检测病变组织的内源性卟啉荧光，并以这种荧光谱作为特征谱，诊断良恶性疾病。经对203例口腔颌面部、皮肤的良恶性病变和600例正常组织荧光谱检测分析，结果显示：恶性肿瘤中有特征荧光表达的占86%（60/70），中、重度不典型增生性病变中有特征荧光表达的占97%（29/30），而14种良性病变（103例）和600例正常精膜、正常皮肤均未见特征荧光。随访中、重度不典型增生性病变患者，发现2例癌变均为特征荧光阳性者。病例检测中，可以清楚地定位2MM直径的微小癌灶。结果表明本检测方法对提高恶性肿瘤早期诊断率是很有意义的。; Characteristics of laser induced autofluorescence spectra of tumors have been studied clinically with a detecting system which consists of an argon laser and an optical multichannel analyzer, Through the analysis of endogenous porphyrin speciFic peaks, 70 cases of malignant tumors, 30 cases of severe dysplasia, 103 cases of benign tumors of chronic inFlammation and 600 cases of normal tissue in oral cavity or skin were diagnosed without any Fluorescent drug The results showed that the positive rate of malignant tumors and dysplastic lesions were 86%(60/70) and 97%(29/30), respectively, while all benign lesions in 103 cases and normal mucosa or skin in 600 persons were negative Two cancer Foci smaller than 2mm were detected by this procedure During Following up by Fluorescence analysis For dysplastic lesions, squamous cell carcinoma occurred in two cases, whose speciFic Fluorescence were positive
