本文作者对罹患中等或重度的7例剥脱性龈炎进行临床、组织病理和萤光免疫学的研究。活检标本用组织化学方法处理,萤光免疫检查按一般方法进行操作。对照组的活检标本取自其他类型的口腔和皮肤疾病,供免疫萤光检查之用。1例经组织病理检查证实为典型的扁平苔癣,并经免疫萤光检查显示基底膜区有纤维蛋白,而在固有层内则有细胞样体(cyto-
The authors performed a clinical, histopathological, and fluorescent immunological study of seven exfoliative gingivitis patients with moderate or severe disease. Biopsy specimens were treated by histochemical methods and fluorescent immunological tests were performed in the usual manner. Biopsies from the control group were obtained from other types of oral and dermatological conditions for immunofluorescence. One case was confirmed by histopathology as a typical lichen planus, and immunofluorescence revealed fibrin in the basement membrane area, while in the lamina propria there was cyto-
