SJO¨GREN'S SYNDROME 환자에게 즉시 임프란트 술식을 행한 치험례
최정환,손동석,이지연,이윤서,안선희,이재목 대한악안면성형재건외과학회 2000 Maxillofacial Plastic Reconstructive Surgery Vol.22 No.5
The old edentulous patients experience xerostomia commonly. They have considerable difficulty in wearing tissue-supported prosthesis and high risk rate of caries. One of them is Sj□gren's syndrome patient. Sj□gren's syndrome is a chronic inflammatory autoimmune disorder that results in a lymphocyte-mediated destruction of exocrine glands. We planned to place implants immediately after extraction in this case of autoimmune disease. The advantages of immediate implant placement include considerable decrease in time from tooth extraction to placement of the final prosthesis, fewer surgical procedures, and better acceptance of the overall treatment plan. We present a case of Sj□gren's syndrome patient treated with immediate implant placement & immediate loading in anterior region and immediate implant placement in posterior region.

Glycyrrhiza uralensis계의 원감초 뿌리에서 추출도는 감초는 여러가지 질병의 약제로 널리 이용되어 왔다. 그 주성분인 gliycyrrhizin은 항염증 활성 및 anti-allergic activity를 갖고 있으며 이러한 생리활성은 aglycone β-gliycyrrhetinic acid 의 활성에 의한 것으로 알려져 있고, β-gliycyrrhetinic acid는 steroid 구조와 유사하며, 면역조절 특성을 갖는 것으로 인식되고 있다. 이러한 β-gliycyrrhetinic acid 의 면역조절 활성에 기여하는 인자와 그 경로에 대하여 조사된 바 있다 Glycyrrhizin은 감초뿌리의 주성분중 하나이며, 그외에도 surgars(14%), starches(30%), flavonoids, saponoids, amonoacids, gums 및 essential oil 등을 포함하고 있다. Licorice, the root extract of Glycyrrhiza uralensis, is used as a medicine for various diseases. Antiinflammatory as well as anti-allergic activities have been attributed to one of its main constituents, glycyrrhizin. These activities are mainly ascribed to the action of the aglycome β-glycyrrhetinic acid. βGlyeyrrhetinic acid has a steroid-like structure and is believed to have immunomodulatory properties, To determine whether interference with complement functions may contribute to the immunomdulatory activity of β-glycyrrbetinic acid. its effect on the classical and alternative activation pathways of human complement were investigated. The main constituent found in the root is glycyrrhizin. The plant also contains various sugars(14%), starches(30%), flavonoids, saponoids, aminoacids, gums, and essential oil etc.

UV/Cl₂(g)에 의한 Si-wafer 표면금속 오염물의 건식세정에 관한 연구
손동수,정광진,최성호,천희곤,조동율 울산대학교 1998 공학연구논문집 Vol.29 No.2
본 연구에서는 실리콘 웨이퍼 표면에 존재하는 미량의 Zn, Fe, Ti 금속 오염물들이 UV-excited chlorine radical을 이용한 건식세정 방법으로 제거되는 반응과정을 연구 하였다. 실리콘 웨이퍼 상에 진공증착법으로 원형패턴이 있는 Zn, Fe, Ti 박막을 증착시켜 상온 및 200℃에서 UV/CI₂세정하였을 때, 염소 래디컬(CI*)이 Fe, Zn, Ti와 반응하여 제거되는 것을 반응 전후 광학현미경과 SEM을 통해 표면 형상 변화를 관찰하였고, in-line으로 연결된 XPS를 통해서 반응 후 웨이퍼 표면에 남아있는 화합물의 화학적 결합상태를 관찰하였으며, UV/CI₂세정 후 실리콘 기판이 손상받는 정도를 알기 위해 AFM으로 표면 거칠기를 측정하였다. 광학현미경과 SEM의 분석에 의하면 Zn와 Fe는 쉽게 제거되는 반면 염화물을 형성하기 보다는 휘발성이 적은 산화물을 형성하는 경향이 강한 Ti은 약간만 제거되는 것을 확인하였다. XPS 분석을 통해서 이들 금속 오염물들이 chlorine radical과 반응하여 웨이퍼 표면에 금속 염화물을 형성하고 있는 것을 확인하였고, UV/CI₂세정처리를 하였을 때 실리콘 웨이퍼의 표면 거칠기가 약간 증가하는 것을 알 수 있었다. 지금까지의 결과를 통해 볼 때, 습식세정과 UV/CI₂건식세정을 병행하면 플라즈마 및 레이저를 사용하는 다른 건식세정 방법에 비하여 보다 저온에서 실리콘 기판의 큰 손상 없이 비교적 용이하게 금속 오염물을 제거할 수 있음을 알수 있었다. The reaction mechanisms of dry cleaning of Zn, Fe and Ti trace contaminants on the Si wafer using UV/CI₂ have been studied by SEM, AFM and XPS analyses. The patterned Zn, Fe and Ti films were deposited on the Si wafer surface by thermal evaporation and changes in the surface morphology after dry cleaning using CI₂and UV/CI₂at 200℃ were studied by optical microscopy and SEM. In addition changes in surface roughness of Si wafer by the cleaning was observed by AFM. The chemical bonding states of the Zn, Fe and Ti deposited silicon surface were observed with in-line XPS analysis. Zn and Fe were easily cleaned in the form of volatile zinc-chloride and iron-chloride as verified by the surface morphology changes. Ti which forms involatile oxides was not easily removed at room temperature but was slightly removed by UV/CI₂at elevated temperature of 200℃. It was also found that the surface roughness of the Si wafer increased after CI₂and UV/CI₂cleaning. Therefore, the metallic contaminants on the Si wafer can be easily removed at lower temperature by continuous processes of wet cleaning followed by UV/CI₂dry cleaning.

Huge Ovarian Fibroma Mimicking Exophytic Uterine Leiomyoma
( Dong Hui Lee ),( In Young Choi ),( Mi Hyun Park ),( Ji Hye Lee ),( Eun Ju Kim ),( Min Kyoung Ko ),( Ji Eun Park ),( In Ae Cho ),( Ji Kwon Park ),( Jeong Kyu Shin ),( Won Jun Choi ),( Soon Ae Lee ),( 대한산부인과학회 2012 대한산부인과학회 학술대회 Vol.98 No.-
Ovarian fibroma, the most common benign solid tumor of the ovary, accounts for 4% of all ovarian tumors, and most frequently manifest during middle age. This tumor is generally asymptomatic and present as unilateral, solid, hard masses. We report a case of ovarian fibroma, which presented with a palpable huge mass with elevated CA-125 levels. The ultrasound examination showed a huge mass with myomatous echogenecity. Pelvic magnetic resonance (MR) imaging showed a 11cm sized exophytic uterine leiomyoma. The mass revealed to be the solid tumor localized in the left ovary after surgery. The final pathologic diagnosis was confirmed the diagnosis of ovarian fibroma. We report here the case of ovarian fibroma mimicking exophytic uterine leiomyoma with brief review of articles.

The characteristics of 124 Phytolacca americana present areas and 88 surrounding absent areas over the country were investigated and compared from July 2016 to Sept 2017. The Phytolacca americana was confirmed as having been nationally distributed and is usually found in roadsides at an altitude of 380 m (26%), forest edges (24%), forests (19%), sunny spots (60%), dry soils (53%), sandy loams (31%) and sand+gravel soils (22%). 321 taxons consisting of 79 families, 209 genera, 289 species, 2 subspecies, 26 varieties and 4 cultivars and 286 taxons consisting of 76 families, 195 genera, 256 species, 2 subspecies, 24 varieties and 4 cultivars were found in the Phytolacca americana present areas and the absent areas, respectively. The relative net contribution degree was found highest in the Phytolacca americana (100) followed by Robinia pseudoacacia (29.4), Humulus japonicus (8.8) and Artemisia princeps (6.0) in the present areas, while it was found highest in Robinia pseudoacacia (100) followed by Humulus japonicus (44.4), Artemisia princeps (35.9), Pueraria lobata (18.6) and Setaria viridis (12.3) in the absent areas. The Raunkier's life form in the present/absent areas was found highest in the therophytes (34%/34%), followed by hemicryptophytes (17%/18%), megaphanerophytes and mesophanerophytes (18%/17%), nanophanerophytes (11%/11%) and geophytes (9%/11%). There was no significant difference in the species diversity between the present (2.141) and the absent (2.124) areas. However, the allelopathic agent and light blocked-out by the Phytolacca americana could possibly inhibit germination and the development of other species; especially, where a difference in species diversity was found high in forests, compared to other habitats (p=0.0605). Accordingly, it is suggested to review possible disturbances of native species habitats in shady spots including forest gaps, although the effect of Phytolacca americana on the ecological system in the suburban open and disturbed areas is not large.
