까le purpose of this study was to evaluate the role of EGF(Epidermal Growth Factor) , EGFR(Epidemlal Growth Factor Receptor), aFGF(acidic Fibroblast Growth Factor, FGF-1), bFGF(basic Fibroblast Growth Factor, FGF-2), FGFR(Fibroblast Growth Factor Receptor), and VEGF(Vascular Endothelial Growth Factor) 띠 the development of the oral squamous cell carcinoma. For this study 6 subjects, diagnosed as squamous cell carcinoma refelTed to the Dept. of Oral Path. College of Dentistry, Kyung Hee University, 2 subjects of normal 이띠 mucosa with any inflammatolY changes were used as expelimental, control groups respectively. AlI the 디ssu es ; expe디me nta l and control group were fixed in 100;ú neutral fOlmalin solution and embeclded in paraffìn , seIial tissue section were made 511m in thickness ancl processecl in the standard way for immunohistochemical methocl, using primary ancl seconclalY antibodies, for EGF(Antirabbit Ig G, rabbit kit at 1:100 dilution), EGFR(Antimouse Ig G, mouse kit at 1:100 dilution), aFGF(Antirabbit Ig G, rabbit kit at 1:100 dilution), bFGF(Antirabbit Ig G, rabbit 써t at 1:100 dilution), FGFR(Antimouse Ig G, mouse kit at 1:100 dilution), ancl VEGF(Antirabbit Ig G, rabbit kit at 1:100 clilution), all BioGenex U.S.A. macle, followed by the Stre ptavidin - Horse Radish Peroxidase(InnoGenex, Human-avidin kit) application, counter stained with Mayer’s hematoxylin stain method. And examined under the biologic microscope, -(no epithelial stain), +(weak or focal epithelial stain), ++(mode rate or focal intensive epithelial stain), +++(intense generalized epithelial staining) for the epithelial, and connective tissue component in squamous cell carcinoma and in nomlal mucosal epithelium on each. Attained results as follows ; 1. It is noted that more intensed reactio n EGF, EGFR, aFGF, bFGF, FGFR, and VEGF on experimental group compare to that on the control group. 2. Increased reaction is noted on the tumor components compare to that in the stromal tissues. 3. Intensed reaction is noted on the basement membrane adjacent to cancer nest to EGF, EGFR, aFGF, bFGF, FGFR, and VEGF 4. It is noted that intensed positive reaction on cancer pearls, cancer components with hyperactivities, in cancer nest. And at the peIiphelY of cancer nest, diffuse moclerate reaction to EGF, EGFR, aFGF, bFGF, FGFR, and VEGF is notecl This results suggest that EGF, EGFR, aFGF, bFGF, FGFR, and VEGF mJy be effectecl to the growth ancl clevelopment of the squamous cell carcinoma.
