The purpose of this study was to investigate the effect of instrumentation with curette, ultrasonic instrument and CO_(2) laser on root surface and result of rubber cup polishing. Eighteen extracted human teeth were used in this study, and divided into six groups, and instrumented as follows. GroupⅠ : Use of curette only Group II : Use of ultrasonic instrument only Group Ⅲ : Use of CO_(2) laser only Group Ⅳ : Rubber cup polishing followed by curette Group Ⅴ : Rubber cup polishing followed by ultrasonic instrument Group Ⅵ : Rubber cup polishing followed by CO_(2) laser After observation of the teeth with scanning electron microscope, the results obtained were as follows : 1. In normal teeth, under same condition, curette produced smooth root surface while ultrasonic instrument and CO(2) laser did not remove calculus completly. 2. In the comparison of polishing between three groups on each root surface, the use of ultrasonic instrument and CO_(2) laser resulted in significantly smoother root surface than curette.

Purpose: To gain insight on the role of AP-1 in transcriptional regulation of vimentin gene during differentiation of HL-60 cells by 12-O-tetradecanoylphorbol-13-acetate (TPA), the levels of vimentin mRNA and AP-1 have been investigated with Northern blot hybridization and DNA mobility shift assay. Materials and Methods: HL-60 cells were grown in RPMI 1640 medium supplemented with 10% heat-inactivated fetal calf serum and antibiotics in a humidified 5% CO_(2) at 37°C. Total RNA was prepared by a modification of the method of Karlinsey et al. Northern blot hybridization was performed by the method of Virca et al. EcoRI fragment of pVIM-GEM was used as probe for vimentin mRNA. DNA mobility shift assay was performed by the method of Lim et al. End labeled DNA probe(Upper strand, 5'-CGCTTGATGAGTCAGCCG- 3') for AP-1 binding activity was mixed with nuclear extracts in a 20 μl reaction volume containing 300 mM KC1, 60 mM HEPES, pH 7.9, 25 mM MgCl_(2), 1 mM EDTA, 1 mM DTT, 60% glycerol, and 2μg of poly[dI-dC]. Results: TPA increased vimentin mRNA levels, with maximal stimulation reached at 24 hr. The level of vimentin mRNA was induced in proportion to the concentration of TPA. TPA-induced vimentin mRNA was almost reduced by actinomycin-D pretreatment. TPA-induced stimulation of vimentin gene was completely reduced by staurosporin pretreatment. In DNA mobility shift assay, AP-1 newly appeared at 24 hr during TPA-induced differentiation and was almost not detected after the pretreatment of staurosporin. Conclusions: These results suggest that the induction of vimentin mRNA during TPA-dependent differentiation in HL-60 cells may be mediated by protein kinases C signal transduction and AP-1 is important to transcriptional regulation.

도남용,나한조,이도용,허준,최지윤,이홍영,임성철 조선대학교 2000 The Medical Journal of Chosun University Vol.25 No.2

Background and Objectives : The cell-cell adhesion molecule E-cadherin is necessary for the maintenance of the epithelial cellular structure. We were designed to confirm the significance of E-cadherin as a marker for differentiation and invasiveness of squamous cell carcinoma of the larynx and hypopharynx. Materials and Methods : Our study was investigated for the immunohistochemical expression of the epithelium-specific cell adhesion molecule E-cadherin in formalin fixed paraffin embedded tissue specimen of 32 cases of squamous cell carcinoma of larynx and hypopharynx. Results : The positive expression of E-cadherin was 56.3%(18 cases) in squamous cell carcinoma of the larynx and hypopharynx. Decreased E-cadherin expression was a stastistically significant correlation with a increased grade of lymph node stage and clinical stage. Reduced expression was seen in the large tumor size and poorly differentiated tumors, but these result was not statistically significant. Conclusion : The expression of E-cadherin may be related with progression of squamous cell carcinoma of the larynx and hypopharynx. But these correlation were not sufficient for the prognostic indicators in squamous cell carcinomas of the larynx and hypopharynx.

임도선 韓國電子顯微鏡學會 2000 Applied microscopy Vol.30 No.3

임신중에 투여된 불소가 흰쥐태아의 법량질형성에 미치는 영향을 알아보고자 어미흰쥐에게 불소를 음용 시킨 후, 생후 11일이 경과된 어린 흰쥐를 희생하였다. 이후, 하악절치를 발치한 후, 법랑단백질의 종류 및 양적 변화와 법랑질 표면의 형태학적 변화를 관찰하였다. 분비법랑질과 성숙법량질에서 추출한 법랑단백질을 전기 영동한 결과, 분비법랑질에서는 분자량 22-24kDa의 amelogenin이 확인되었는데, 대조군에서보다 불소투여 농도가 높아질수록 양이 감소하였다. 성숙법량질에서는 분자량이 68kDa의 enamelin이 확인되었으며, 대조군에 비해 불소투여 농도가 높을수록 양적인 증가가 확인되었다. 그리고 주사전자현미경을 사용하여 법량질 표면을 관찰한 결과, 대조군에서는 평탄하고 매끄러운 표면인 반면에 불소투여군은 거친 표면과 균열이 심하게 나타났고, 불규칙한 소공이 관찰되었다. 그리고 일부에서는 균열과 함께 주머니 같은 결절과 법랑질 형성부전을 확인하였다. 따라서 본 연구결과, 태아발생과정 중 투여된 불소가 법랑질형성에 관여하는 법랑모세포에 영향을 줌으로써 단백질의 형성과 분비가 지연 또는 억제되며, 수분과 단백질 제거에 관여하는 법랑모세포의 기능을 저하시키는 것으로 사료된다. 이러한 단백질의 비정상적인 형성과 분비는 법랑질 형성부전 등의 법량질형성에 전반적으로 영향을 마치는 것으로 확인되었다. The present study has been carried out to investigate the effect of fluoride toxicity on the morphology as well as inorganic chemical constituents of rat teeth. Rats were administered sodium fluoride at dose of 0ppm, 100ppm, 200ppm and 300ppm at the beginning of pregnancy. Animals were perfused intravascularly with glutaraldehyde and the incisors were removed. Changes in the protein composition of the secretory and maturation enamel were investigated using polyacrylamide gel electrophoresis (SDS PAGE). And the enamel surface of incisors was examined under scanning electron microscope (SEM). Changes of protein quantities were found significantly in high levels fluoride administration for experimental groups compared with control. The SDS PAGE analysis demonstrated as follows. In control group, secretory phase enamel protein, amelogenins, was detected more quantities than experimental group. The enamelin, presence in maturation phase enamel, showed more quantities than control enamel with an increasing fluoride concentration in the drinking water. Also, the scanning electron micrographic data showed hypoplastic, tough, uneven, pitted and cracked enamel surfaces covered with granular deposits as a result of excessive intake of fluoride. From these results we conclude that high dose of fluoride administration leads to severe structural alterations on the enamel surface and these structural changes could be through defective mineralization.

A resistance value of the metal oxide sensor for alcohols was measured by metal oxide senor (FOX2000). T30/1 sensor showed the best response to propanols. The pattern analysis could be measured to ppm and resistance could be processed as various forms. We could find that six sensor responses for propanols were better than those of methanol, when alcohols were displayed at the same time on the radar axis plane with maximum value of △R/Ro by sensors. Alcohols and distilled water were analysed with a principle component and they could be confirmed as being separated clearly.

Basal cell nevus syndrome(BCNS)is a hereditary condition transmitted as an autosomal dominant trait that exhidits high penetrance and variable expressivity. There ara many potential complications which have been reported in association with the naevoid basal cell carcinoma syndrome. The data upon which this review is based has been retrieved from published case reports in Korean dental and medical literatures between the years 1981 to 2002. this survey included unpublished 3 patients by reviewing patients files and charts from the Dental hospital, Chosun University during same periods. We found 33 subjects who met the diagnostic criteria for BCNS reported by Evans et al. Relative frequencies of associated complications are presented and compared with those of the recent English survey. The frequencies of most manifestations are similar. Odontogenic keretocyst (OKC)and palmar and/or plantar pits, and hypertelorism were the most frequently observed anomalies. OKCs are often the first signs of BCNS and can be detected in patients younger than 9 years of age. however, the relatively low frequency of basal cell carcinomas and ectopic calcification were two major difference. This study more clearly defines the possible complications of the syndrome and gives earlier guidelines for counselling and screening affected and at risk persons.
