Desmoplastic ameloblastoma is a rare histologic variant of ameloblastoma. It shows important differences in anatomic distribution, histologic appearance, and radiographic findings compared with the general type of ameloblastoma. It is histologically characterized by an abundance of densely collagenous stroma and radiographically a mixed radiolucent-radiopaque lesion. We present three cases of desmoplastic ameloblastoma. All the patients complained on buccal swelling with or without pain and the sites of occurrence were the anterior and the premolar region. Plain radiographs showed mixed radiopaque-radiolucent lesion with ill-defined or diffuse sclerotic margin and no external root resorption. Additionally, CT scans revealed buccal expansion and relatively well-defined margin of the lesions. The clinical and radiographic features of the presented cases were compared with those of the desmoplastic ameloblastoma in the previous literatures.

The purpose of this study was to compare the different canal irrigation methods to prevent the formation of precipitate between sodium hypochlorite (NaOCl) and chlorhexidine (CHX). Extracted 50 human single-rooted teeth were used. The root canals were instrumented using NiTi rotary file (Profile .04/#40) with 2.5% NaOCl and 17% EDTA as irrigants. Teeth were randomly divided into four experimental groups and one control group as follows; Control group: 2.5% NaOCl only, Group 1: 2.5% NaOCl + 2% CHX, Group 2: 2.5% NaOCl + paper points + 2% CHX, Group 3: 2.5% NaOCl + preparation with one large sized-file + 2% CHX, Group 4: 2.5% NaOCl +95% alcohol+ 2% CHX. The teeth were split in bucco-lingual aspect and the specimens were observed using Field Emission Scanning Electron Microscope. The percentages of remaining debris and patent dentinal tubules were determined. Statistical analysis was performed with one-way analysis of variance (ANOVA). Energy Dispersive x-ray Spectroscopy was used for analyzing the occluded materials in dentinal tubule for elementary analysis. There were no significant differences in percentage of remaining debris and patent tubules between all experimental groups at all levels (p > .05). In elementary analysis, the most occluded materials in dentinal tubule were dentin debris. NaOCl/CHX precipitate was detected in one tooth specimen of Group 1. In conclusion, there were no significant precipitate on root canal, but suspected material was detected on Group 1. The irrigation system used in this study could be prevent the precipitate formation. 이 실험의 목적은 NaOCl과 CHX의 혼합사용 시, 발생하는 침전물의 형성을 막기 위해 두 용액간의 접촉을 줄일 수 있는 여러 가지 방법을 비교하고, 관찰된 침전물의 원소를 분석하는 것이다. 발거된 50개의 단근치를 사용하였으며 2.5% NaOCl을 이용하여 .04 taper ProFile #40까지 근관형성 하였다. 치아는 다음과 같은 근관세척 방법에 따라 4개의 실험군과 1개의 대조군으로 나누었다; 대조군: 2.5% NaOCl, 1군: 2.5% NaOCl + 2% CHX, 2군: 2.5% NaOCl + paper points + 2% CHX, 3군: 2.5% NaOCl + .04/#45 근관확대 + 2% CHX, 4군: 2.5% NaOCl +95% alcohol+ 2% CHX. 근관세척 후 치아를 양분하고 치관부, 중간부, 치근부 세부위로 나누어 전계 방사형 주사 전자현미경을 통하여 잔사 비율, 개방 상아세관 비율, 상아세관 내 물질의 원소분석을 시행하였다. 실험결과, 실험군 사이에 잔사비율과 개방된 상아세관 비율 비교에서 통계학적으로 유의할 만한 차이는 나타나지 않았다. 1 군의 한 시편에서 C의 함유량이 높게 나타났으며 N과 Cl도 함께 검출되어 para-chloraniline으로 추정되며, 1 군의 다른 시편과 나머지 실험군에서는 O, P, C, Ca의 순으로 함유량이 높은 것으로 나타나 수산화인회석으로 추정된다. NaOCl 세척 후 바로 CHX 세척을 한 군에서 PCA로 의심되는 물질이 검출된 바, 두 용액의 직접적인 접촉을 피하기 위해 주의가 필요하며, 본 실험에 사용된 여러 근관 세척방법 이용 시 침전물의 형성을 예방할 수 있을 것이다.

최은경,박문흠,김두회,구영건,김상수 昌原大學校 基礎科學硏究所 2001 基礎科學硏究所論文集 Vol.13 No.-

Bismuth layered structure ferroelectric thin films, BIT and donor (V, Nb and W) doped BIT, were prepared on the Pt/Ti/SiO2/Si substrates by sol-gel method. BIT film was characterized by strong c-axis prepared orientation. In the case of donor doped BIT thin films, the degree of c-axis prepared orientation decreased systematically V-BIT→W-BIT→Nb-BIT and Nb-BIT film was shown random orientation. Surface morphologies of BIT and V-BIT films had a plate-like and Nb-BIT and W-BIT had a mixture of plate-like and rod-like. In the results of ferroelectric hysteresis loops, the remanent polarization (2Pr) of random-oriented Nb-BIT capacitor was 26 μC/cm2, and this value was over two times higher than that of 12 μC/cm2 for BIT capacitor. The polarization fatigue up to 4.5×1010 read/write switching cycles of W-BIT capacitor was shown superior to the other capacitors. The polarization of the W-BIT capacitor decreased only 10% of the initial value after 4.5×1010 switching cycles.

최순영,김창숙,이명혜,황문옥,민경희 숙명여자대학교 자연과학연구소 1991 자연과학논문집 Vol.- No.2

원유 분해세균에 의한 원유 분해능을 조사한 결과, Xanthomonas campestris M12. Xanthomonas sp. M28, Acinetobacter lwoffi G1, and Klebsiella pneumoniae L25, 그리고 Pseudomonas maltophilia N246 등의 순서로 나타났다. Xanthomonas campestris M12, Xanthomonas sp. M28, 그리고 Pseudomonas maltophilia N246 균주 모두 octane 분해시의 온도는 30℃에서 최적이었으며, 최적 pH는 X. campestris M12와 Xanthomonas sp. M28이 7.0∼7.5이었고, P. maltophilia N246이 7.5∼9.0이었다. N246 균주의 최적 NaCl 농도는 3.0∼3.5%이었다. P. maltophilia N246와 X. campestris M12는 모두 플라스미드를 갖고 있음을 확인하였고, N246 균주로부터 플라스미드를 제거하였을 경우 octane 분해능이 소실되었으므로 이 플라스미드 위에 octane 분해 유전자가 있음이 확인되었다. 이 균주의 OCT 플라스미드의 크기는 118kb이었다. 또한, N246 균주는 ampicillin 항생제에 내성을 나타내었다. Xanthomonas campestris M12. Xanthomonas sp. M28. Acinetobacter lwoffi G1, and Klebsiella pneumoniae L25, Pseudomonas maltophilia N246 were screened to increase the ability for crude oil utilization. All of these could utilize hexadecane and octane with the exception of N 246 strain for only octane biodegradation. Thus N246, M12, and M28, strains were specially examined for octane oxidation. Octane biodegradation by three strains showed the optimal conditions at 30C, pH7.0∼9.0 and 0.2∼0.3% octane concentration as a substrate. It was found that P. maltophila N246 and X. campestris M12 had plasmid and the cured plasmid from N246 strain lost octane utilization. Therefore, it was confirmed that certain genes for octane utilization were located on OCT plasmid in N246 strain. The size of OCT plasmid in N246 strain was 118 kb. The N246 strain was resistant to ampicillin.

새로 고안한 풍선박리기를 사용한 임상경험

최문수,고경석,박상훈 大韓成形外科學會 1999 Archives of Plastic Surgery Vol.26 No.3

A new balloon dissector, a modification of a Foley catheter, was devised and it can be used either as a dissector or a tissue expander. Since most operating time was spent in balloon manipulation (inflation/deflation), the duct for saline injection was made to be wider than the Foley catheter. As a result, the balloon could be inflated faster than before. In order to reduce the scar at the donor site, harvest of the sural nerve using endoscopic technique is currently applied, but utilization of this method is technically difficult and requires a long operating time. For these reasons, new our method of using a balloon dissector was devised. The balloon dissector can also be used for immediate intraoperative tissue expansion for the reconstruction of small skin defects without distortion. We have found that the advantages of using the new balloon dissector include a reduction in operating time, preservation of the perforating vessels, and primary closure with less tension. In addition, this simple and inexpensive instrument is cost-beneficial to patients.

문진영,최미정,남경수,임종국 동국대학교 경주대학 1996 東國論集 Vol.15 No.-

Antioxidant effects of aqueous Siho extract on lipid peroxidation were determined by TBA value and also by lipid peroxidation value during the autoxidation of Iinoleic acid. Siho extracts exhibited markedly antioxidant aCtivity, which inhibited 99% of linoleic acid peroxidation. And Siho extracts showed 42% scavenging effect on α,α-dlphenyl-β-pjcrylhydrazyl radical, also exhibited a 60-94% inhibitory effect on superoxide generation. Siho extracts dose-dependently protected the cell death induced by tert-butyl hydroperoxide (t-BHP) and significantly increased cell viability In the normal rat liver cell(Ac2F) . These results suggested that Siho might play a protective role in lipid peroxidation by free radicals. Key Words: lipid peroxidation ; Siho extracts; scavenging effect
