The molecular mechanisms of the carcinogenesis of oral squamous cell carcinomas (OSCCs) are highly variable and result in different features of tumor progression, i.e., local tissue destruction and metastasis to regional lymph nodes. A case of OSCC arising from proliferative verrucous leukoplakia (PVL) was analyzed for its protein expression profile by immunoprecipitation (IP) – high performance liquid chromatography (IP-HPLC) by using 72 antisera and comparing results with those of KB cells. OSCC arising from PVL showed stronger expressions of proteins associated with cell proliferation (MPM2, PCNA, eiF5A, DHS, DOHH), cell survival (pAKT, MDM2, survivin), matrix proteolysis (elaffin), tumor suppression (p16, p21, PTCH1), the WNT/β-catenin pathway (SHH, WNT1, APC, β-catenin, snail), proinflammation (TNFα), angiogenesis (HIF, CMG2, vWF), and cellular protection (HSP-70, FAK, caveolin) and of oncoproteins (STAT3, 14-3-3, K-RAS, PUMA, PIM1) and growth factors (EGFR, bFGF) than KB cells. On the other hand, KB cells showed stronger expressions of proteins associated with apoptosis (caspase-3, caspase-8, caspase-9, PARP, FAS, FASL, TGase-1, BCL2, BAD, BID, BAK, FLIP), matrix proteolysis (MMP-2, MMP-9), transcription signaling (NFkB, p38, E2F-1, HO-1), and tumor suppression (p53, RB1, PTEN) and of oncoproteins (DMBT1, CEA) and growth factor (TGF-β1, c-erbB2, VEGF) than OSCC arising from PVL. These data indicate the cells of OSCC arising from PVL are more resistant and more robust than KB cells. Furthermore, they suggest the oncogenic signalings of OSCC arising from PVL play important roles in the aggressive growth and rapid tumor metastasis to regional lymph nodes

Halitosis is a bad odor in mouth. The etiology of halitosis is multifactorial including intra-oral and extra-oral causes. It affects social interactions in many people. The aim of this study is to investigate an association between recognition group and non-recognition group by evaluating halitosis level and systemic factors. Nineteen participants who visited Department of Periodontology of Seoul National University Bundang Hospital were enrolled. Volatile sulfur a compounds (VSCs) were measured by Oral ChromaⓇ, a questionnaire was requested and oral exam was carried out in all subjects. Female is more sensitive than male for oral malodor. VSCs level of hydrogen sulfide(H2S) and methyl mercaptan(CH3SH) in male is higher than that in female. Participants who gave appeal dry mouth seem to recognize halitosis.

The aim of this study was to examine the effects and the sensitivity of antifungal therapy for patients with oral candidiasis and to investigate the relationship among the signs & symptoms of patients and the ratio change of Candida species to antifungal therapy. Candida fungus culture test with ChromeIDTM Candida agar (CAN2) was carried out more than twice for 10 patients who visited Oral Medicine department of Chonnam National University Dental Hospital during the period from Dec. 2015 to Aug. 2016. After culturing the smear sample before and after antifungal therapy in ChromeIDTM Candida agar (CAN2), the number of colonies was counted to compare. Patients were divided into 5 group according to the therapeutic effects of the antifungal agents used: 1) high susceptibility to nystatin, 2) low susceptibility to nystatin, 3) high susceptibility to fluzonazole, 4) low susceptibility to fluzonazole, and 5) increased ratio of new Candida species. Although nystatin is used as first-line therapy in oral candidiasis, it is desirable to use fluconazole if patients had a history of the low sensitivity to nystatin or chemotherapy. Even if the patient's symptoms and signs are improved, there is a possibility of oral candidiasis recurring, so that clinicians should be careful during the treatment with antifungal agents.

be involved in the development of oral SCC. If we compare the morphologic features of NHOK to IHOK according to calcium concentration by TEM, IHOK have been gained wide acceptance as a model system for HPV-linked oral carcinogenesis. We already have established immortalized oral keratinocytes(IHOK) transfected by E6 and E7 gene. The purpose of this study were to examined the ultrastructural features of cultured NHOK, IHOK, and HN4 oral squamous cell carcinoma cell line, and to apply these results to oral carcinogenesis in the future. NHOK from healthy retromolar pad was primarily cultured at 37oC and 5% CO2. IHOK, and HN 4 cell line which were cultured under 0.15 and 1.2mM Ca++ of KBM bullet kit. For transmission electronmicroscopy(TEM), under preconfluency, and after 3 days of postconfluency under 1.2mM Ca++, cultured NHOK, IHOK, and HN4 cell line were immediately fixed in 2.0% glutaraldehyde in 0.1M cacodylate buffer(pH 7.4) at 4OC for 1h. The ultrathin sections were stained with uranyl acetate and lead citrate, and examined by TEM. The obtained results were as follows. 1. TEM of cultured NHOK under 1.2mM Ca++ showed increased tonofilaments, and vaculated ovoid cells with cornified envelope, while cultured IHOK showed prominent microvilli, unilateral desmosome in microvillus, and tonofilaments. 2. TEM of HN 4 cell line sowed numerous microvilli, increased N/C ratio, and lateral desmosome in microvilli under 0.15mm, while under 1.2mM well forming desmosomes. From the aboving results, under high calcium cultured IHOK showed less tonofilaments than that of cultured NHOK, while cultured IHOK, and HN 4 cell lines showed more increased desmosomes under high calcium. It was suggested that the ultrastructural changes of cultured IHOK would be accepted as intermediate stage cells for studying oral carcinogenesis.

From ancient soldier to mordern athletes, it has been discussed that some oral appliance have enhanced performance and decreased stress or improve strength. Since mouth guard was used by Italien Boxer on 1930’s for prevent of orofacial injury, some investigators have researched the co-relationship between jaw position and strength. This experiment was performed to study the relationship between mouth guard and E.M.G. 20 Taekwondo students were participated in this study. They were wearing Mouth guard and checked Brachialis physical activity by E.M.G. The muscle activity of mouth guard wearing group was higher than that of non-wearing group.

Cystic Hygroma Occurring on the Left Side of Neck of an Adult : A Case Report and Literature Review

김근환,김진욱,최소영 대한구강악안면병리학회 2020 대한구강악안면병리학회지 Vol.44 No.3

With few reported cases, cystic hygroma is known to occur mainly in patients under the age of two years. Cystic hygroma can eventuate in any area; however, it mostly occurs in the cervicofacial area. If cystic hygroma occurs in this area, then the lesion may be related to the vital structures. Therefore, a complete surgical resection may be impossible and difficult to perform. This incident affects the high recurrence rate of cystic hygroma. The purpose of this report is to present a case of cystic hygroma occurring on the left side of the neck of a 47-year-old male patient as well as a review of literatures.

rhBMP-4 and Anti BMP-4 Antibody Effect on ALP Expression of Gingival Fibroblast

이일권,장현선 대한구강악안면병리학회 2013 대한구강악안면병리학회지 Vol.37 No.1

Gingival fibroblasts (GF) are the most abundant cell type in periodontal connective tissues, andhave distinct functional activities in the repair of periodontal tissues and in inflammatory periodontal diseases. Human gingival fibroblasts (hGF) can be used for periodontal tissue engineering. This study examined whether the alkaline phosphatase of hGF is enhanced by recombinant human BMP-4 and/or Anti human BMP-4 antibody. hGF was obtained from the excised gingival tissue of an implant patient undergoing 2nd surgery. The tissue was incubated at 37℃ in 5% CO2 and 95% humidity, and the cultivating media was changed every 2 days. The 2nd passage hGF cells were cultured in a medium containing Dulbecco's modified Eagle medium (DMEM) supplemented with 10% fetal bovine serum and 1 X antibiotic antimycotic solution. The control hGF was cultured for 7 days without rhBMP-4/Anti human BMP-4 antibody. The experimental groups were cultured for 7 with BMP-4 (10 ng/ml) and/or Anti human BMP-4 antibody. This study evaluated the differentiation of hGF to osteoblasts using alkaline phosphatase assay. In the experimental groups, the hGF showed abundant positive ALP staining. Among the experimental groups, the experimental group 3 (mixture of rhBMP-4 (20ng/㎖) and Anti human BMP-4 antibody (50000ng/㎖) showed most abundant positive ALP staining. In the control group, the hGF showed weak positive ALP staining. Overall,these results suggest that the ALP expression of hGF can enhanced by rhBMP-4 or mixture of rhBMP-4/ anti human BMP-4 antibody.
