        Glycyrrhizin, an active constituent of Glycyrrhiza, was chemically extracted and its hypocholesterolemic activities were studied in rats. Following were the results: 1. The Sprague Dowley rats fed with the standard diet were divided into 4 groups, $50{\sim}60$ in each, and glycyrrhizin was given in doses of 0 (control), 0.5, 1.0 and 2.0mg per 100gm body weight daily for 10, 20, 30, and 60 days. Glycyrrhizin showed more or less the hypocholesterolemic activities in all animals. All of the animal groups to which 1. 0mg and 2.0mg of glycyrrhizin were given died before 60 days, while no mortality cases was noted in the group to which 0.5mg of glycyrrhizin was given. 2. Cholesterol administration induced hypercholesterolemia in all experimental animals, however, simultaneous administration of cholesterol with 0.5mg of glycyrrhizin suppressed the rise of the total serum cholesterol levels. The former group did not survive until 56 days, while the latter did. 3. Glycyrrhizin also Suppressed the cholesterol biosynthesis and incorporation of cholesterol in the liver tissues. 4. Glycyrrhizin induced the increase of the fecal excretion of the sterol compounds.

        남서태평양 라우분지 TA19-1 해산과 TA19-2 해산의 지자기 특성 연구

        김창환,Kim, Chang Hwan 대한자원환경지질학회 2014 자원환경지질 Vol.47 No.4

        한국해양과학기술원에서는 심해열수광상탐사를 위하여 2009년에 남서태평양 라우분지의 열수광상유망지역에 대하여 지구물리조사를 실시하였다. 그 중 TA19-1 해산과 TA19-2 해산에 대한 해상자력탐사 결과를 이용하여 이 해산들의 지자기 특성을 분석하였다. TA19-1 해산은 단순한 1개의 원추형 형태로 정상부는 함몰된 칼데라를 가진다. TA19-2 해산은 TA19-1 해산에 비해 규모가 크고 대규모 함몰대를 가진 칼데라가 나타나고, 칼데라 서쪽으로 정상부가 나타나며 능선들도 여러개 존재하는 형태로서 TA19-1 해산에 비해 복잡한 해저지형을 가지고 있다. TA19-1 해산의 자기이상은 정상부를 중심으로 북쪽에는 고이상대가 남쪽에는 저이상대가 나타나는 단순 쌍극자 이상 형태로 분포하고 있다. TA19-2 해산의 자기이상은 해산 북쪽 사면에 고이상대들이 위치하고 있고, 칼데라 서쪽에 위치한 정상부를 중심으로 고이상대가 나타나고 그 주변 및 칼데라 주위로 저이상대가 분포하며 TA19-1 해산에 비교하여 복잡한 형태의 자기이상을 나타낸다. 해저지형, 지자기 자료의 결과는 TA19-2 해산이 TA19-1 해산에 비해 복잡한 화산활동의 결과로 형성되었다는 것을 지시한다. 열수분출대의 가능성이 높은 저자화이상대들은 주로 해산의 정상부 및 칼데라와 칼데라 주변부에 주로 나타나는데 이는 단층 및 균열 등에 따른 열수 분출에 의한 암석 변질의 영향 등으로 판단되며, 정상부와 칼데라 내에 나타나는 높은 고자화대는 volcanic sill, intrusion 등 후기 화성활동과 연관성이 있을 것으로 사료된다. We conducted the geophysical survey of possible hydrothermal vent sites at 2009, in the Lau Basin, the south western Pacific and analyzed the magnetic characteristics of TA19-1 and TA19-2 seamounts. TA19-1 is a cone-shaped seamount with a caldera summit. TA19-2 seamount is bigger and shows more complicated topography than TA19-1 seamount. TA19-2 has a large caldera, a summit in the west side of the caldera and several crests. Simple dipole anomalies with a high over the north and a low over the south occur in TA19-1 seamount. High magnetic anomalies are located in the northern flank and the summit of TA19-2 seamount and low anomalies around the summit and the caldera. The results of bathymetry and magnetic data suggest that TA19-2 seamount might have more complicated magmatic process than TA19-1. Low magnetization zones are located over the summit, the calderas and the caldera rims. The magnetization lows indicate that submarine hydrothermal vents, along faults and fracture zones, could have caused an alteration of magnetic minerals. The magnetization highs over the summit and the calderas might have been related with later magmatisms like volcanic sills, intrusions.

      • 디지털 치의학의 과거와 현재 그리고 미래

        김창환,Kim, Chang Hwan 대한심미치과학회 2015 Journal of the Korean Academy of Esthetic Dentistr Vol.24 No.1

        치과계에서 캐드캠이 보급되면서 본격적으로 사용한 지 15년이 넘었다. 코핑 정도의 역할에서 구치부 전부관으로 확대되었고, 최근에는 전치부에서도 많이 사용하는 추세이다. 장비의 발전도 비약적이었지만 지르코니아 블록의 발전이 가장 많이 이루어졌다. 개개인의 능력이나 경험 차에 의해 차이는 있을 수 있겠지만, 도재를 올리지 않고 지르코니아에 컬러링만으로도 얼마든지 색을 표현 할 수 있다. 또한 캐드 디자인 만으로도 표면의 질감을 표현하는 것에 우리가 알고 있는 만큼 가능하다. 본 논문에서는 이러한 디지털 치과학의 변천과정을 정리해 보고자 한다. Since its introduction to the dentistry, the CAD/CAM technology has been used over fifteen years. The application of CAD/CAM started from coping fabrication, expanded to the posterior full crown, and anterior restoration manufacture has also become widespread recently. While the development of machine was rapid, the advance of zirconia block was the fastest. Although some differences exist among individuals, the various natural tooth color can be expressed through the zirconia coloring itself without porcelain build up. And the texture characteristics can be reproduced just by CAD design. In this article, the development history of digital dentistry was summarized.

        독도 화산체 정상부해역의 정밀해저지형 및 지구물리학적 특성 연구

        본 연구는 현재까지 수행된 독도 화산체 정상부 해역의 정밀수심 및 지구물리 조사 자료를 종합하고 분석하여 정상부 해역의 정밀해저지형 및 지구물리학적 특성을 연구하였다. 독도 연안역 동도와 서도 사이 연결 수로는 약 10 m 이내의 얕은 수심을 이루고 있다. 독도 화산체 정상부해역의 전체적인 수심은 동도와 서도의 육지부부터 수면 아래 약 30 m 까지는 불규칙하며 급한 경사면을 가지고, 그 후 수심 약 30 m부터 수심 약 80 m 까지는 경사가 점차 낮아지다가 수심 약 80 m 이하로 완만한 경사를 보이면서 외해역으로 깊어진다. 독도 육지부와 그 북동쪽 및 북서쪽으로 연장되는 암반들은 독도를 생성시킨 화구륜의 잔해로 판단되며 동도와 서도는 화구륜의 남쪽 한부분일 가능성이 큰 것으로 생각된다. 또한 정상부 해역의 해저지형에서는 소규모의 움푹 패인 지형들이 나타나는데 이는 독도 형성 후 나중에 생성된 소규모 분화구의 흔적들로 추정된다. 독도 정상부 해역은 주로 암반이 많이 분포하지만 곳곳에서는 모래 퇴적층들도 나타나는 것을 볼 수 있다. 독도 화산체 정상부에는 계단형의 경사면들이 나타나는데 이는 제4 기에 나타난 해침, 해퇴 등 해수면변화에 의해 만들어진 해저단구로 유추되며, 지역별로 차이가 있기는 하지만 주로 약 30 m, 60 m, 80 m 및 약 100 m의 수심대를 위주로 하여 몇 개의 주요 해저단구가 나타나는 것으로 판단된다. 자기이상도 및 아날니틱신호도를 살펴보면 수면 위 독도에서 연장되는 북동 및 북서쪽의 이상대들은 화구륜의 잔해로 예상되는 암반들의 위치와 유사하게 나타난다. We studied the detailed bathymetry and the geophysical characteristics of the summit of the Dokdo volcano using mutibeam echosounding and geophysical survey data. The bathymetry around the main east and west islets of the Dokdo volcano shows very shallow within about 10 m water depth. From near islets to about 30 m b.s.l., the shallow water area has very steep slope and many irregular sunken rocks. The area from about 30 m to about 80 m b.s.l. shows gentle rises and falls, and less steep slope. The area from 80 m b.s.l. has gradually flat undulation and smooth slope seabaed and is extended to offshore. The main islets of the Dokdo volcano and the rocky sea bottom elongated from the islets might be the residual part of the eroded and collapsed main crater of the Dokdo volcano. The bathymetry and the seafloor image(from backscattering) data show small craters, assumed to be formed by the eruption of later volcanism. The seafloor images propose that, except some areas with shallow sand sedimentary deposits, there are typical rocky bottom such as rocky protrusions and lack of sediments in the main morphology of the survey area. The stepped slopes of the seabed are deduced to be submarine terraces. The several prominent submarine terraces are found at the summit of the Dokdo volcano, suggesting repetition of sea level changes(transgressions and regressions) in the Quaternary. The results of the magnetic anomaly and the analytic signal have a good coherence with other geophysical consequences regarding to the location of the residual crater.

        양혈사물탕가미방(凉血四物湯加味方)이 Allergy성(性) 접촉(接觸) 피부염(皮膚炎)에 미치는 영향(影響)

        김창환,김경준,Kim, Chang-Hwan,Kim, Kyung-Jun 대한한방안이비인후피부과학회 2005 한방안이비인후피부과학회지 Vol.18 No.1

        Experimental drug was applied to a white male mouse taken ill with allergic contact dermatitis to investigate the effects of Yanghyulsamultanggamibang. 1. In case of skin moisture, when it was checked 72 hours later, there showed up meaningful differences among the normal, control, and sample groups. Especially, the moisture increased more noticeably in the sample group than in the control group. 2. With regards to RBC count in blood, it increased more in the control and sample groups than in the normal group when it was checked both in 24 hours and 72 hours. When it was checked in 48 hours, the number of RBC in the sample group increased the most, and the count in the control group increased more than in the normal group. 3. About the neutrophil rate in WBC count, it increased meaningfully more both on the control and sample groups than in the normal group in 24 hours. When the rate was checked in 48 hours, it increased the most in the sample group, and it increased more in the control group than in the normal group. When in checked72 hours later, it increased substantially more in the control group than both the sample and normal group. 4. As of the lymphocyte rate in WBC count, when measured in 24 hours, it increased in the normal group than in the control and sample groups. In 48 hours, it increased the most in the normal group, and it increased meaningfully more in the control group than in the sample group. 5. Regarding the total IgE, when measured 24 hours later, it increased noticeably more in the normal group than in the control and sample groups. In 48 hours, there showed up substantial differences among the normal, control and sample groups. In particular, it increased meaningfully more in the control group than in the sample group. 6. When the sample of skin tissue was examined, the corneal layer restoration increased more in the sample group than in the normal group. The above-mentioned results prove that Yanghyulsamultanggamibang can be taken when allergic contact dermatitis develops on the skin. Long-term observation afterward is also advised.
