title: [Direct immunofluorescent technic of analyzing fibrinogen in the differential diagnosis of certain diseases of the oral mucous membrane].
abstract: This paper reports the use of direct immunofluorescent technique in diagnoses of 80 cases in which 5 kinds of diseases of the oral mucous membrane are included. The results demonstrate that fibrinogen is deposited in basement membrane zone in 100% of lichen planus cases and 21.4% and 75.0% in chronic lupus erythematosus and benign lymphoid hyperplasia respectively. In leukoplakia and chronic infection it is negative. Therefore, the direct immunofluorescent technique is likely a reliable method for diagnosis of certain kinds of diseases of the oral mucous membrane.
