The purpose of this study is to discover the characteristics and the change of the framed structure with triple beam. 61 existing buildings with the triple beam structure were selected and analyzed extensively. The result of this study could be described in detail like below. The triple beam structure is used in the highly graded and symbolized building like the Buddhist sanctum and the Confucian sanctum. And the triple beam structure was chiefly used in $1600{\sim}1800's$. Generally, 1 Koju-type with Toikan(退間) is applied to the triple beam structure. Despite of the sameness of framed structure, there is a tendency that the rear Toikan(後退間) is used in the Buddhist sanctum and the front Toikan(前退間) is used in the Confucian sanctum. This different application of the Toikan(退間) resulted from the different spatial characteristics which reflect function and grade of the building. The application of Sangjungdori(上中道里, upper purlin) and two Danyeon(短椽, short rafter) is a necessary consequence, because Jungbo(중보, middle beam) is located between Daebo(대보, beam) and Jongbo(종보, small and high located beam) as an additional member of frame. And these are essential characteristics of the framed structure with triple beam. The triple beam structure is formed in a transitional period, as the result from eliminating the inner high-column from the 2 Koju and double beam structure. Though the Daebo is longer, the structure is more stable. But the rate of application of the triple beam structure is low, because it does not exceed the double beam structure in merits. Some of buildings with the triple beam structure has the asymmetrical characteristic in design, which is appeared in the latter period of Joseon Dynasty.

낙우송(Metasequoia glyptostroboides)으로부터 분리한 flavonoid의 금속단백분해효소-9 발현 억제 활성

양재영,이호재,고영희,권병목,전효곤,Yang Jae-Young,Lee Ho-Jae,Kho Yung-Hee,Kwon Byoung-Mok,Chun Hyo Kon 한국생명과학회 2005 생명과학회지 Vol.15 No.2

기질 금속단백분해효소(MMP)는 기저막이나 간질성 조직 등에 있는 세포외기질 성분을 분해하여 상처 치유, 태아의 발생, 종양세포의 침윤과 전이 등을 포함하여 조직이 재구성되는 과정에서 생리학적 및 병리학적인 과정 양쪽 모두에 매우 중요한 역할을 한다. 본 연구에서는 MMP-9 유전자의 발현을 억제하는 물질을 천연물에서 탐색하였고, 탐색된 시료 중에서 높은 역가를 가진 낙우송과의 Metasequoia glyptostroboides가 선택되었다. 여러 가지 flavonoid 성분을 가지고 있는 Metasequoia glyptostroboides를 이용하여 4개의 biflavonoid와 2개의 monoflavonoid 구조의 물질을 분리하였고, 이 flavonoid들은 sciadopitysin, isoginkgetin, bilobetin, 2, 3-dihydrohino-kiflavone, luteolin, apigenin으로 정제하여 구조를 밝히고 zymography, WST-1을 이용한 세포독성시험, northern blot 등의 실험을 통하여 각 화합물의 구조적인 특성과 함께 MMP-9 유전자 발현을 억제하는 효과가 있는 것을 확인하였다. Matrix metalloproteinases (MMPs) are a family of structurally and functionally related zinc-dependent enzymes responsible for proteolytic degradation of extracellular matrix components such as base membrane or interstitial stroma. MMPs play an important role in a variety of physiological and pathological tissue remodeling processes, including wound healing, embryo implantation, tumor invasion and metastasis. Since MMP-9 (gelatinase B) has unique ability to cleave type IV collagen, gene expression of MMP-9 has been focused on as a pharmacological target. Flavonoids are a class of compounds that are widely spread in plants. In the coures of screening for the suppressors of MMP-9 gene expression from natural products, Metasequoia glyptostroboides was selected. Six flavonoids, sciadopitysin, isoginkgetin, bilobetin, 2,3-dihydrohinokiflavone, luteolin and apigenin were purified as suppressors of MMP-9 gene expression from M. glyptostroboides. The suppressing activity of the isolated flavinoids on the MMP-9 gene expression was measured by gelatin zymography and Nothern blot analysis.

Osteochondroma is one of the most common benign tumors that occur in the bone, but in the head and neck region, osteochondroma appears rarely. Malocclusion, temporomandiublar disorders and facial asymmetry can occur in most cases with osteochondroma of the mandibular condyle. Most surgeons prefer massive removal of osteochondroma and reconstruction of condyle, simultaneously, to prevent various complications, such as a lateral open bite on the contralateral side. We report a surgical treatment and reconstruction of osteochondroma on a mandibular condyle through intraoral approach.

양재영,양정안,서정완,이승주,Yang Jea-Young,Yang Jung-An,Seo Jung-Wan,Lee Seung-Joo 대한소아신장학회 2001 Childhood kidney diseases Vol.5 No.1

목 적 : 99mTc DMSA 신스캔 평면영상은 급성신우신염과 신반흔의 진단에 유용한 검사로 알려져 있다. 최근에는 99mTc DMSA 신스캔 평면 영상에 Single-photon emission computed tomography(SPECT) 영상을 추가하여 예민도를 높일 수 있다고 하였다. 저자들은 소아 요로감염에서 99mTc DMSA 신스캔 평면영상에 추가된 SPECT영상의 진단적 가치를 평가하고자 하였다. 대상 및 방법 : 1997년 1월부터 1999년 7월 까지 이대 목동병원 소아과에서 요로감염으로 진단 받고 99mTc DMSA 신스캔 평면영상에 SPECT영상을 추가 시행하였던 130명 (260 kidney unit)과 신반흔으로의 진행을 파악하기 위하여 추적검사를 시행하였던 22명(44 kidney unit)을 대상으로 하였다. 신스캔은 99mTc DMSA를 주사하고 3시간후 전면상과 후면상의 평면영상을 얻고, 이어서 저에너지 범용 조준기가 장착된 회전형 카메라 (Starcam 4000-I U.S.A. GE)를 사용하여 SPECT Axial과 Coronal 영상을 얻어 진단율을 비교하였다. 통계는 Yates 교정 후 Chi 검정하였다. 결 과 : 급성신우염 환자의 진단율은 SPECT영상에서 47.7$\%$로 평면영상의 35.4$\%$에 비해 12.3$\%$가 높았다. 신단위로 평가하면 SPECT 영상에서는 32.3$\%$로 평면영상의 25.8$\%$에 비하여 6.5$\%$가 높았다. 평면 영상 음성인 18신단위(6.9$\%$)가 SPECT 영상에서는 14신단위(5.4$\%$에서 국소성결손, 4신단위 (1.5$\%$)에서 다발성 결손이었고 평면영상에서 양성인 1신단위 (0.4$\%$)가 SPECT 영상에서 음성이었다. 평면영상에 비하여 SPECT영상이 더 우수한 경우가 17.3$\%$, 동일한 경우가 82.3$\%$, 미흡한 경우가 0.4$\%$였다. 99mTc DMSA 신스캔의 신반흔 진단율은 SPECT 영상에서는 43.2$\%$로 평면영상의 36.4$\%$에 비하여 6.8$\%$ 높았다. 평면영상에서 양성은 SPECT영상에서 모두 양성이었고, 평면영상에서 음성이 SPECT영상에서 양성인 경우는 6.8$\%$(3신단위)이었다. 평면영상에 비하여 SPECT 영상이 우수한 경우가 11.4$\%$, 동일한 경우가 88.6$\%$이었다. 결 론 : 99mTc DMSA신스캔 평면영상에 추가된 SPECT영상은 급성신우염과 신반흔의 진단율을 높이고 더 우수한 영상을 얻을 수 있었다. Purpose : 99mTc DMSA renal scan have been widely used not only for tile evaluation of renal scars but also for the diagnosis of acute pyelonephritis. Recent studies have shown SPECT images have higher accuracy than the planar images with some controversy. We evaluated the availability of the SPECT images adding to planar images for the diagnosis of acute pyelonephritis(APN) and renal scar in children with urinary tract infection (UTI). Methods : 130 children with UTI (260 kidney units) and 22 follow-up children (44 kidney units) were included between January 1, 1997 and July 31, 1999 at Ewha University Mokdong Hospital. Planar Anterior and posterior images and SPECT axial and coronal images of 99mTc DMSA renal scan were obtained with Starcam 4000-i U.S.A. GE at 3 hours after 99mTc DMSA I.V. injection. The data were analyzed by Chi square test after Yates's correction. Results : The detection rate of the acute pyelonephritis by SPECT images was 12.3$\%$ higher than that of planar images ($47.7\%\;vs\;35.4\%$) by the patient and 6.9$\%$ higher also ($31.9\%\;vs\;25.4\%$) by the kidney unit. 18 kidney units with negative planar images had focal defect in 10 kidney units (3.8$\%$) and multifocal defect in 8 kidney units (3.1$\%$) on SPECT images, but 1 kidney unit with positive planar image had negative SPECT image. SPECT images were superior to tile planar images in 17.3$\%$. identical in 82.3$\%$ and inferior in 0.4$\%$ to planar image. The detection rate of tile renal scars by SPECT images was 13.7$\%$ higher than planar images by the patient ($68.2\%\;vs\;54.5\%$) and 6.8$\%$ higher also ($43.2\%\;vs\;36.4\%$) by the kidney unit. SPECT images were superior to the planar images in 17.3$\%$ and identical in 82.3$\%$ to planar image. Conclusion SPECT images had shown higher detection rate and better image than planar images for the diagnosis of the acute pyelonephritis and the evaluation of the renal scars. (J.
