치성낭종에서 c-fos, c-jun 발현에 관한 면역조직화학적 연구 Immunohistochemical Study of C-fos and C-jun Expression in Odontogenic Cysts
pp.335-344
The purpose of this study was to evaluate the role of c-fos and c-jun expression in the odontogenic cysts. For this study, 20 subjects of odontoenic dysts: 8 subjects of keratocysts and 12 subjects of periodontal cysts referred to the Dept. of Oral Pathology, School of Dentistry, Kyung Hee University, were used as experimental group, and 5 subjects of normal oral mucosa without any inflammatory changes. were used as control groups respectively. All the tissues of experimental and control group were fixed in neutral formalin solution and embedded in paraffin, serial tissue section were made 5㎛ in thickness and processed in the standard way for immunohistochemical method, using primary antibodies, for c-fos, c-jun was diluted at 1:100 each, followed by the super sensitive non-biotin horse radish peroxidase system with DAB as chromogen application, counter stained with Gill's hematoxylin stainmethod, mounted. And examined under the biologic microscope with the criteria of -(no epithelial stain), +(weak or focal epithelial stain), ++(moderate or focal intensive epithelial stain), +++(intense generalized epithelial staining) for the epithelial, and stromal tissues on each. Attained results as follows. In normal oral mucosa, it is noted that moderate positive responses in cytoplasm and nuclei to c-fos and c-jun protein on each.. In the responses to c-fos, c-jun protein, moderate positive responses in nuclei and cytoplasms of the epithelial lining in keratocysts and periodontal cysts, but more intense reaction is noted on the periodontal cyst compare to that on the keratocysts. In the responses to c-fos, c-jun, it is noted that more intense responses in odontogenic cyst compare to that in the oral mucosa. In the responses to c-fos and c-jun on submucoas of oral normal mucosa, focal epithelial stain was noted. and more intensive reaction was noted on the odontogenic cysts, most in periodontal cysts. This results suggests that c-fos and c-jun protein effected on the induction of development and growth of the cysts
