The Anti-cancer Effect of Oriental Medicine Chung-Ri-Ja-Gam-Tang in the Mouse with Metastatic Lung Cancer. Proceedings of International Symposium on East-West Medicine, Seoul. 231-243, 1999.-The oriental medicine Chung-Ri-Ja-Gam-Tang is an herbal medicine which has been used for pulmonary diseases and known as having immune stimulatory effects. It has been known effective in lung cancer. So we studied the effects and the mechanisms of this herbal medicine it the mouse with metastatic lung cancer. The metastatic lung cancer of the mouse was produced with melnoma cell line(B16BL/6).5×10□/mouse tumor cells were injected intravenously to the CDF1 mouse via tail vein. The mice were divided 4 groups. The first group was treated with 50mg/kg extract of Chung-Ri-Ja-Gam-Tang per oral for 10 days after cancer cell injection, second group treated with saline after cancer cell injection, the third group with medicine without cancer cell, and the last group with saline only. After 10 days treatments some of the mice were scarificed and the lung and spleen was removed. The survival duration, weight change, the number of metastatic cancer nodule of the lung, the NK cell activity, the capacity of cytokines(INF-γ,INF-α,IL-2) production and the proliferation activities of mouse lymphocytes were measured. The surival times of the group 1 mice were longer and the weight loss was less than the group 2 significantly. The number of the metastatic nodule of the lung were decresed in the group 1 than the group 2. The production of INF-γ,was increase in group 2 than group 3 and 4, IL-2 production was increased in group 1 than group 2,3,4 significantly. There was no difference in TNF- α production and proliferation activity of lymphocyte in each group. The NK cell activity was significantly increased in group 1 than group 2,3,4. We conclude that the Chung-Ri-Ja-Gam-Tang has the effect of increasing the NK cell activity of the CDF1 mouse with metastatic lung cancer(B16BL/6). And it is suggested that the increased production of the IL-2 is the mechanisms of enhanced NK cell activity.

이 논문은 현대건축의 혼란한 상황 속에서 자신의 빛깔을 잃지 않고 지역성을 바탕으로 건축활동을 전개하는 건축가 마리오 보타의 단독주택에서 건축적 형태와 공간을 구성하는데 중요한 건축어휘로 나타나고 있는 보이드(Void)에 주목하여 이를 유형별로 분류하고 그것들의 특성들을 파악하여, 보이드가 지닌 형태적 의미와 공간적 의미를 연구한 것이다. 연구결과는 다음과 같다 : 1) 보이드는 보이드 자체를 감싸주는 외피의 존재유무에 따라 폐쇄형(제1유형)과 개방형(제2유형) 등 2가지 유형으로 구분할 수 있다. 2) 이러한 보이드는 유형별로 외피의 역할, 입면에 있어서 좌우대칭의 형성 역할을 담당하고 있다. 3) 보이드는 유형별로 평면상으로 주택의 정면중앙부에 위치하고 있으며 주택 배면의 계단실과 마주보고 배치되어 있는데, 주변환경에 대한 조망, 내부공간으로의 빛의 유입, 외부에서 내부로의 전이적 공간의 형성 등에 이바지하고 있다. 이러한 연구결과는 국내에서는 연구가 전무한 건축가 마리오 보타에 대한 실질적인 이해와 접근을 제공할 것이다. In the single family houses by Mario Botta, the architectural language, "void" is an important vocabulary in architectural form and space. In this study, I will analyse the void, which can be seen in the single family houses by Botta. The results of this study are as follows: 1) The void, which is seen in Mario Bottas single family house, is an important architectural vocabulary in constituting the form and space of house. This specific architectural language appears in every 16 single family houses. 2) According to the existence of an outside envelope, it is possible to classify the void in two groups, i.e. the closed type and the open type. 3) This voids contribute to form the exterior skin and the symmetry in the facade. 4) The void in the plan is located in the center of the front of the house, and it was also at a confronting relation with the staircase. It also functioned the vista into the surrounding environments, introduction of light into interior space, and formation of transition exterior into interior.

We reported a case of pancreatic pseudoaneurysm, involving pancreaticoduodenal artery, developed after endoscopic retrograde cholangiopancreatography(ERCP) with endoscopic sphinterotomy. A 54 year old woman was transferred to our hospital due to sustained hematochezia and hypovolemia. A week before admission, she underwent ERCP with endoscopic sphinterotomy for acute cholangitis in local clinics. She developed abdominal pain and hematochezia at 12 hours after the procedures. A post procedure contrast enhanced computed tomography of abdomen demonstrated a pseudoaneurysm in inferior portion of pancreatic head. This was not present on the pre procedure contrast enhanced computed tomography of abdomen and was thought to arise from the pancreaticoduodenal artery as a complication of the pre sphincterotomy. She was brought to our emergency room in a state of hypovolemia. A upper endoscopy showed active bleeding from ampula of vater. An celiac angiography demonstrated pancreatic pseudoaneurysm involving inferior pancreaticoduodenal artery and selective coil embolization of was performed.

1987년 7월부터 1990년 6월까지 연세의대 세브란스 병원에 입원한 전신성 흉반성 낭창 환자 103예를 대상으로 조사하여 신경학적 증상과 징후가 있거나 뇌 전산화 단층 촬영상 또는 뇌파 검사상 이상이 있는 경우, 또는 정신병적 증상과 징후가 나타난 경우를 중추 신경계 낭창이라고 정의하였을때 다음과 같은 결과를 얻었다. 1) 전체 103예중 43예(41.7%)에서 중추 신경계 침범을 보였다. 2) 중추 신경계 낭창군은 비 중추 신경계 낭창군에 비하여 높은 초기 사망률을 나타내었다. 3) 중추 신경계 낭창군은 비 중추 신경계 낭창군에 비하여 신장 기능이 의의 있게 저하되어 있었다. 4) 중추 신경계 낭창군과 비 중추 신경계 낭창군 사이에 유병기간, 침범된 장기, 자가면역 항체 등에 있어서는 유의한 차이를 보이지 않았다. 결론적으로 전신성 홍반성 낭창환자, 특히 신장 기능이 저하되어 있는 환자는 중추 신경계 침범 여부를 조심스럽게 관찰하여 조기에 진단하고, 중추 신경계 침범이 확인된 경우는 사망률을 저하시키기 위하여 보다 적극적인 치료를 요할 것으로 사료된다. Central nervous system involvement in systemic lupus erythematosus (CNS lupus) is characterized by difficulty in it's proper diagnosis, treatment, and poor prognosis. We analyzed 103 systemic lupus erythematosus patients who have admitted to Severance Hospital, Yonsei University, from July 1987 to June 1990. The results were as followed: 1) 43 cases out of 103 systemic lupus erythematosus patients had central nervous system involvement. 2) Immediate mortality in CNS lupus was significantly higher than non-CNS lupus group. 3) Renal functions in CNS lupus were more significantly impaired than non-CNS lupus group. 4) There was no significant difference in duration of disease, number of organ involved, autoantibodies between CNS and non-CNS lupus group. These results suggest that patients with imparied renal function should be carefully followed up for early detection of central nervous system involvement. And, if central nervous system involvement is suspected, then more aggressive treatment may be required to reduce high mortality rate.

UV-TiO_(2) 반응기를 이용하여 Escherichia coli와 Aspergillus oryzae var. oryzae의 살균효과를 측정하였다. 254 ㎚에서 최대 14 watt의 자외선 방출량을 내는 램프를 원형 Pyrex유리관 중앙에 설치하였고 TiO_(2)는 석영관에 박막증착(Thin Film Coating)된 형태와 슬러리 형태로 나누어 회분식으로 살균정도를 측정하였다. E. coli에 대한 살균력은 1.7× 10^(7) cells/㎖에 대해 5분간 자외선 조사를 하였을 경우 2.0× 10^(2) cells/㎖으로 감소하였고, 자외선 조사와 함께 슬러리 형태의 TiO_(2)를 첨가하였을 경우에는 3.4× 10 cells/㎖으로, 자외선 조사와 함께 TiO_(2)가 석영관에 박막증착된 경우에는 7.6× 10^(2) cells/㎖으로 감소하였다. 한편 위와 같은 조건에 유리관 하부에서 기포를 주입후 11분 동안 자외선을 조사시킨 경우에는 1.3× 10^(2) cells/㎖으로, 자외선 조사와 함께 슬러리 형태의 TiO_(2)를 첨가하였을 경우에는 1× 100 cells/㎖으로, 자외선 조사와 함께 TiO_(2)가 박막증착된 경우에는 7.9× 10 cells/㎖을 나타내었다. 결국 UV-TiO_(2) 반응기에 사용되는 TiO_(2)가 슬러리 형태일 때 최대 살균효과를 나타내었으나 기포가 첨가되었을때는 오히려 살균에 장애를 받는 것으로 나타난 반면 석영관에 박막증착된 경우에는 기포가 첨가되는 것이 살균에 효과적인 것으로 관찰되었다. The killing effect of UV-TiO_(2) photocatalytic system on the Escherichia coli DH5-慣 and Aspergillus oryzae var. oryzae (KCTC 6095) was studied. The UV lamp which emits maximum 14 watts at 254 nm was set on the center of pyrex round glass tube. Two types of TiO_(2), one of which is slurry and another which is thin film coated form, were used to determine the killing effect. When UV was irradiated to 1.7 * 10^(5) cells/??of E. coli for 11 min, the living cell number decreased to 4.0 * 1.0^(0) cells/?? The effect of UV system together with slurried TiO_(2) was less than 1 cells/?? whereas that of UV-coated TiO_(2) system decreased to 7.1 * 10^(3) cells/?? To study the effect of bubble on the killing of microorganisms, air was bubbled to the bottom of glass tube. When 1.7 * 10^(5) cells/??were exposed to UV for 11 min in combination with air bubble, the living cell number decreased to 1.3 x 10^(2) cells/?? In the same condition except the addition of slurried TiO_(2), the living cells were 1 * 10^(2) cells/?? However, more cells could be killed by the system which consists of UV, coated TiO_(2), and air bubble (7.9 * 10^(1) cells/??. From these results, it was found that UV-slurried system is the most effective one, but its killing effect is not stimulated by air bubble. However, bubbling was very effective in the UV-coated TiO_(2) system.

토양 미생물인 Streptomyces tubercidicus에서 분리한 GTPcyclohydrolase Ⅰ 저해제

한지만,김시욱,이인화,박열,정혜광,윤성명,유진철 조선대학교 약학연구소 1998 藥學硏究誌 Vol.19 No.1

GTP cyclohydrolase I (EC 3.5.4.16) catalyzes the conversion of GTP to D-erythro-7,8-dihydroneopterin triphosphates and formic acid. and thus performs the first committing step in the biosynthesis of the pteridine moiety of folk acid in microorganisms and of tetrahydrobiopterin in higher animals. GTP cyclohydrolase I isolated from Streptomyces tubercidicus was inhibited by DL-6-methyl-5,6,7,8-tetrahydropterin and xanthopterin, and was not inhibited by tetrahydrofolic acid, pterin, pterin-6-carboxylic acid, biopterin, neopterin, ribofravin. These results suggest that bacterial GTP cyclohydrolase I may be regulated by its metaboilic end product.

김태섭,김선주,박시영,전만중,김규태,김창윤,정종학,백성옥,사공준 대한산업의학회 2007 대한직업환경의학회지 Vol.19 No.1

목적: 신축초등학교와 대조학교를 선정하여 교실 내 포름알데히드와 TVOCs를 측정하고 컴퓨터 신경행동검사를 이용하여 실내공기 오염물질이 학생들의 인지기능에 미치는 영향을 평가하였다. 방법: 신축초등학교 5학년 71명을 실내공기 오염물질 노출군으로 하고, 개교한지 12년째인 대구시의 일개 초등학교 5학년 2학급 63명을 대조군으로 하여 실내공기 오염물질농도 측정 및 컴퓨터 신경행동검사를 실시하였다. 결과: 신축학교에서 의도적으로 창문을 개방한 학급에서 1교시 포름알데히드 농도는 34.6 ㎍/㎥, 4교시에는 27.3 ㎍/㎥, 창문을 개방하지 않은 학급에서 1교시 80.2 ㎍/㎥, 4교시 127.1 ㎍/㎥, 대조학교에서는 2학급 각각 1교시에 12.6 ㎍/㎥, 7.5 ㎍/㎥, 4교시에 19.8 ㎍/㎥, 25.2 ㎍/㎥였다. TVOCs의 경우 신축학교의 의도적으로 창문을 개방한 학급에서 1교시에 농도는 487.2 ㎍/㎥, 4교시에 428.2 ㎍/㎥, 창문을 개방하지 않은 학급에서 1 교시에 농도는 1,283.5 ㎍/㎥, 4교시에 1,715.4 ㎍/㎥, 대조학교의 경우 2학급에서 각각 1교시에 농도는 240.9 ㎍/㎥, 150.8 ㎍/㎥, 4교시에 농도는 371.9 ㎍/㎥, 448.0 ㎍/㎥였다. 부호숫자 짝짓기의 평균반응시간은 대조학급이 1교시에 2,585 msec에서 4교시에 2,459 msec으로 감소한 반면 신축학교의 창문을 의도적으로 개방한 학급은 2,343 msec에서 2,510 msec으로, 평소대로 수업한 학급은 2,340 msec에서 2,563 msec으로 반응시간이 각각 167 msec, 223 msec 증가하였다. 1교시의 부호숫자 짝짓기 의 반응시간을 100%로 했을 때 창문을 의도적으로 개방 한 학급은 4교시에 5.9% 증가하였고(p<0.01), 평소대로 수업한 학급은8.3% 증가하였다(p<0.01). 반면에 대조학급은 4교시에 5.0% 감소하였다(p<0.01). 결론: 향후 학교의 실내공기질의 안전성 평가는 샘플링 된 공기의 오염수준의 측정뿐만 아니라 학생들의 건강영향도 함께 고려되는 것이 바람직할 것이다. Objectives: Most studies on the indoor air quality of newly built schools have focused only on the number of schools exceeding a standard or on subjective symptoms, such as sneezing, irritated eyes and an irritated nose. However, there has been no report on how poor indoor air quality affects children's academic performance. This study evaluated the effects of indoor air quality on the neurobehavioral performance of elementary school children. Methods: This study measured the indoor air pollutants and compared children's performance, using a computerized neurobehavioral test, between a newly built and a 12-year-old school. In addition, a questionnaire was administered regarding the indoor air quality related symptoms of children in a newly built and a 12-year-old school. Results: In the newly built school, the formaldehyde levels in the 1^(st) and 4^(th) classes with an open window were 34.6 and 27.3 μg/㎥, respectively. The levels in the 1^(st) and 4^(th) classes with the window closed were 80.2 and 127.1 μg/㎥, respectively. In the 12-year-old school, the formaldehyde levels in 1^(st) and 4^(th) class with open and closed window were 12.6 and 7.5 μg/㎥, and 19.8 and 25.2 μg/㎥, respectively. With respect to total volatile organic compounds, the levels in the 1^(st) and 4^(th) classes with the window open in the newly built school were 87.2 and 428.2 μg/㎥, respectively. In the 1^(st) and 4^(th) classes with the window closed, the total volatile organic compounds were 1,283.5 and 1,715.4 μg/㎥, respectively. In the 12-year-old school, the total volatile organic compounds were 240.9 and 150.8 μg/㎥, and 371.9 and 448.0 μg/㎥ in the 1^(st) and 4^(th) classes, respectively. In the case of a newly built school, the performance of the students in the neurobehavioral test in the 4^(th) class with the window closed was 8.3% lower than for those in the 1^(st) class with the window closed, but was only 5.9% lower when the windows were open. There was a statistical significant difference in the total numbers of symptoms between the two schools. Conclusions: These results suggest a proper evaluation of the indoor air quality within schools is required into both the level of contamination and the health effects of these contaminants toward children.
