For more effective intraperitoneal chemotherapy, the authers made 5-fluorouracil-polyglycolic acid composite disks(FU-PGA disks) with 5-fluorouracil and polyglycolic acid, a biodegradable polymer. We inserted the FU-PGA disk into the peritoneal cavites of Sprague-Dawley male rats, the control and three experimental groups; one FU-PGA disk insert group(300mg/kg), two FU-PGA disk insert group(600mg/kg), and three FU-PGA disk insert group(900mg/kg). The control group received a similar number of PGA disk inserts. A pharmacokinetic study was performed to measure the 5-fluorouracil concentration in the peritoneal fluid, blood, and tissues(liver, kidney and heart) at 24 hours, 72hours and 168 hours after insertion of the FU-PGA disk. Light and electron microscopic studies were done. The results were as follows: 1) The number of white blood cells and platelets decreased after FU-PGA insertion. The degree was proportional to the duration and amounts inserted. The change in the number of red blood cells varied slightly. 2) Light microscopically, slight changes were noted at 168 hours in the 3 disk insert group (900mg/kg). Mild fatty change and hepatocyte degeneration around the central veins of the liver were noted, with vacuolar degeneration in the proximal convoluted tubules of the kidney. 3) Electron microscopically,the liver showed focal increases of lipid droplets in the hepatocytes, and irregular nuclear membrane with focal nucleolar segregation of the fibrillar and granular elements. Also the double membranous structure of the hepatocytes and Kupffer cells was widened with bleb formation. The kidney showed wide separation of the nuclear double membrane in the proximal convoluted tubular cells and mesangial cells, with vacuolation and myelin figure formation in the mitochondria of the proximal convoluted tubular cells, at 72 hours and 168 hours in the 2 to 3 FU-PGA insert groups. The heart showed focal loss of cristae,vacuolation and myelin figure formation in the mitochondria of the 2 to 3 FU-PGA insert groups. In conclusion, despite the large amont of FU-PGA inserted, the histopathological changes in the liver, kidney and heart were slight, and consonant with the very low amount of 5-fluorouracil concentrations detected in the liver, kidney and heart. The above results suggest that the FU-PGA composite can serve as a new device for releasing drugs in a controlled manner and easily targeted to intraperitoneal organs. This device can improve the efficacy of intraperitoneal chemotherapy for gastric cancer.

To evaluate the in-vivo effects of mitomycin-C-polyglycolic acid composite(MMC-PGA) the disk: shaped composite were implanted into the peritoneal cavity of the Sprague-Dawley rats. The pathologic changes were examined at various time points up to 12 weeks. Initially the soft tissue around the inserted disks showed capillary congestion at 3 days. Inflammatory infiltrates with foreign body giant cells appeared from the 2nd week and reached peak response at 6-8 weeks. These reaction diminished prominently at 12 weeks. No specific pathologic change was found in the liver, the kidneys, and the heart. The above results suggest that the MMC-PGA composite can serve as a new device for intraperitoneal chemotherapy of various types of cancers.

백락주,송진원,송기준,고은영,정기모,이용주 대한감염학회 1998 감염 Vol.30 No.5

목적: 1997년과 1998년 경기도의 농경지에서 채집한 4종의 야생들쥐 211수와 강원도 산악지대에서 채집한 3종 302수의 야생들쥐를 대상으로 O. tsutsugamushi의 Gilliam주와 Karp주에 대한 항체검사를 실시하여 농경지와 산악지대에서 서식하는 야생들쥐의 항체양성율을 비교하고자 하였다. 방법: 경기도 6개 지역과 강원도의 7개 산악지대에서 야생들쥐 총 513수를 채집하여 O.tsutsugamushi의 Gilliam주와 Karp주에 대한 항체검사를 간접형광항체법으로 실시하였다. 결과: 경기도에서는 등줄쥐, 갈밭쥐 및 멧밭쥐에서 항체양성을 확인할 수 있었고 항체양성율은 지역에 따라 차이가 있었지만 전체적으로 17.5%의 항체양성율을 나타내었다. 강원도의 7개 산의 해발 500미터 이상의 지점에서 채집한 야생들쥐중 등줄쥐와 흰넓적다리붉은쥐서는 항체양성을 확인할 수 있었고 대륙밭쥐는 모두 항체음성으로 나타났다. 전체적으로는 3.3%의 항체양성율을 나타내었다. 결론: 국내에서 발생하는 열성질환인 쯔쯔가무시병은 농경지에서 서식하고 있는 야생들쥐를 숙주로 하는 털진드기의 매개로 사람에 감염된다. 야생들쥐의 리켓치아 감염은 최우점종인 등줄쥐를 대상으로 연구가 이루어져 왔으며 항체양성율은 15∼20%로 보고되었다. 본 연구에서도 경기도의 농경지에서 채집한 야생들쥐의 리켓치아 감염율은 17.5%로 나타났다. 그러나 강원도 산악지대에서 채집한 야생들쥐의 감염율은 3.3%로 나타나 큰 차이를 보이고 있다. 이와 같은 결과는 두지역에서 서식하는 야생들쥐의 종별 차이에 관계가 있는 것이 아니고 O. tsutsugamushi의 매개곤충으로 알려진 L. palpale, L. pallidum, L.scutellae, L.orientale, L. zetum의 시식밀도나 서식분포에 관련이 있을 것으로 사료되며 향후 이에 대한 추가적 연구가 요구된다. Background: This study was designed to determine the serpositivity for rickettsial infection among wild rodents captured in farms of Kyunggi province and in mountains of Kangwon province in Korea. Methods: A total of 513 wild rodents of 5 species were captured in 1997∼1998. Serological evidence for rickettsial infection was obtained using Orientia tsutsugamushi antigens by indirect immunofluorescent antibody technique(IFA). Results: 168 Apodemus agrarius, 35 Microtus fortis 3 Micromis minuets and 2 Eothenomys regulus were captured in Kyunggi province, of which 32 Apodemus agrarius, 4 Microtus fortis, 1 Micromis minutus were IF antibody positive against O. tsutsugamushi. 196 Apodemus agrarius, 77 Apodemus peninsulae and 29 Eothenomys regulus were captured in Kangwon province, of which 4 Apodemus agrarius and 5 Apodemus peninsulae were positive. Conclusion: Seropositivity rate against O. tsutsugamushi of wild rodents captured in Kyunggi and Kangwon provinces were 19.6% and 3.0% by IFA tests, respectively.

허혈 조건부여가 심근기능의 회복에 미치는 영향 : 적출 심장모델을 이용한 실험연구 Isolated heart experimental study

백광제,김준식,한승백,전영진,이인성 大韓應急醫學會 1999 대한응급의학회지 Vol.10 No.2

Background: Brief episode of coronary artery occlusion(i.e.,ischemic preconditioning) makes the heart more resistant to injury from a subsequent ischemic insult. Although a great deal of effort has been made in studying ischemic preconditioning, the underlying mechanism of ischemic preconditioning and its effect on hypothermic insult has not been elucidated. This study was performed to see whether ischemic preconditioning protects against the depression of cardiac contractility induced by hypothermic cardioplegic arrest/reperfusion. And recently, adenosine was known to have some correlation with the mechanism of preconditioning. If so, does this effect remain after the blockade of adenosine receptor by 8-phenyl theophyline? Method: Twenty-four Sprague-Dawley rat weighed 250-350g were used and divided into three groups. Rat hearts were removed rapidly, and each isolated heart paced with a rate of 180/min was perfused by modified Krebs-Hensleit buffer(KHB) solution on a Langendorff apparatus for an hour. After obtaining baseline data including left ventricular pressure(LVP), dp/dt, and coronary flow, cardiac arrest was induced by perfusion of 0℃ crystalloid cardioplegic(St Thomas) solution. After that, all hearts were stored in the same St Thomas solution at same temperature for 2 hours. In group Ⅰ(control group), the heart was reperfused by KHB solution. In group Ⅱ(preconditioning group), the heart was subjected to two 2-minute episode of global ischemia followed by 5 minute reperfusion with KHB solution(preconditioning) before cardiac arrest. In group Ⅲ(phenyl theophylline group), the heart was subjected to preconditioning procedure and 8-phenyl theophylline at 10μM in concentration was added to KHB solution at time of reperfusion. Observing parameter was obtained in each group at 10, 20, 40 and 60 minutes after starting reperfusion and compared statistically by use of one way ANOVA test(STASTICA, release 4.5). p-value less than 0.05 was considered significant. Results: Although depressed LVP, dp/dt, and coronary flow were seen in all groups during the reperfusion period, the preconditioned group showed more effective recovery of LVP than that of the control group, especially at 10, 20 and 40 minutes(p<.05). We failed to demonstrate the difference between the phenyl theophylline group and the control group(p=NS). Conclusion: These results suggest that ischemic preconditioning has protective effect on recovery state of hypothemic cardioplegic arrest/reperfusion. Its protective effect was limited during early reperfusion stage and was blocked by adenosine blocker.

백락주,송진원,송기준,박광숙,최영주,강주일,이용주 대한감염학회 1997 감염 Vol.29 No.6

목적:국내 야서중에 한타바이러스의 숙주는 등줄쥐와 집쥐로 알려져 있으나, 한국에 서식하고 있는 다양한 야생 설치류를 채집하여 한타바이러스에 대한 항체검사를 실시하여 새로운 혈청형의 한타바이러스가 있는지를 혈청학적으로 규명하고자 하였다. 방법:국내에 서식하고 있는 야생 설치류를 1995년 10월부터 1996년 10월까지 7종 551수의 야시와 4종 97수의 소형동물을 채집하여 한타바이러스에 대한 항체검사를 간접형광항체법으로 실시하였다. 결과: 1) 야서 7종 551수와 소형동물 4종 97수를 대상으로 한탄바이러스의 감염율은 등줄쥐 17.2%(29/162), 흰넓적다리붉은쥐 8.7%(2/23), 대륙밭쥐는 25%(2/8), 그리고 땃쥐는 7.1%(1/14)이었다. 그리고 야생토끼는 8.8%(7/80)가 서울바이러스에 대한 항체를 가지고 있었다. 등줄쥐의 양성혈청중 대부분은 서울바이러스와 일부는 푸말라바이러스, 프로스펙트힐바이러스, 뉴욕바이러스와도 교차반응이 있었다. 흰넓적다리붉은쥐 2수와 대륙밭쥐 2수는 5가지 한타바이러스 모두에 교차 반응이 있었다. 2) 다람쥐는 9.5%(28/283)가 채집지역에 관계없이 한탄바이러스에 대한 항체를 가지고 있었고 항체기는 1:16 내지 1:256으로 비교적 낮았으며 서울바이러스, 푸말라바이러스, 프로스켁트힐바이러스와 뉴욕바이러스에 각각 반응하는 것도 일부는 교차반응을 보이는것도 있다. 청설모는 10.3%(7/68)가 한탄바이서르에 대한 항체를 가지고 있었으며 항체가는 1:16 내지 1:1,024이었으며 일부는 교차반응이 있었다. 3) 야생토끼의 서울바이러스에대한 항체양성율은 8.8%(7/80)이었으며 이중에 2수는 한탄바이러스와 교차반응이 있었고, 푸말라바이러스, 프로스켁트힐바이러스, 뉴욕바이러스와는 교차반응이 없었다. 항체가는 1:16 내지 1:64로 비교적 낮았다. 결론:등줄쥐는 한탄바이러스에 의한 감염이지만 흰넓적다리붉은쥐, 대륙밭쥐, 다람쥐 그리고 청설모의 일부는 한탄바이러스가 보다 다른 한타바이러스에 대한 항체가가 높았고 특히 일부 다람쥐 혈청은 푸말라바이러스 혹은 프로스켁트힐바이러스에만 반응하였다. 그리고 야생토끼는 서울바이러스에 대한 감염율이 높은 것으로 보아 국내에 한탄바이러스와 서울 바이러스 이외에 새로운 혈청형의 한타바이러스가 있는 것을 사료된다. Background: Hantavirus are widley distributed in rodents populations even in geographical areas where hemorrhagic fever with renal syndrome(HFRS) has not been reported. Multiple species of Murid and Arvicolid rodents serve as the natural reserviors of hantaviruses. Serologic diagnosis using hantaviral antigens indicates that hantaviruses are widley distibuted in wild rodents. This study were designed to find the distribution of hantaviruses among wild rodents and small mammals in Korea, 1995-1996. Methods: Rodents were trapped alive in selected areas. A total of 551 wild rodents from 7 species and 97 small mammals from 4 species were captured in Korea. Serologic evidence for hantavirus infection were tested using five hantavirus antigens by indirect immunofluorescent antibody technique(IFA). Among 162 Apodemus agrarius, 23 Apodemus peninsulae, 8 Clethrionomys regulus, 6 Microtus fortis, 1 Mus musculus, 283 Tamias sibiricus, 68 Sciurus vulgaris, 14 Crocidura laciura, 80 Lepus sinensis, 2 Capereolus capereolus and 1 Nyctereutes procyonoides. Results: 29 A. agrarius, 2 A. peninsulae, 1 C. laciura, 2 C. regulus, 27 T. sibiricus and 7 S. vulgaris were sero positive agaist hantaan virus and 7 L. sinensis were IF antibody positive against Seoul virus. Some of Tamias sibiricus were only seropositive against puumala virus or prospect hill virus. Conclusion: This data suggests that new serotypes of hantavirus might distribute among rodents in Korea.

백숙은,최영진 동아시아식생활학회 2004 동아시아식생활학회지 Vol.14 No.3

This study was conducted to figure out the nutritional nature of seafoods categorized according to the medicinal effects and the usages introduced in Lim-Won-Sib-Rheuk-Ji, one of the well-known encyclopedias published during the Chosun Dynasty. They were compared with those introduced in other cooking books in order to find out how they were used in the diet of real-life. The seafoods of the book were first categorized into the fish 20, the mollusk 5. the crustacea 4, and the shellfish 7, and reptile according to the biological taxonomy, and then each one was reviewed in terms of the taste and the food-nature. Generally, the fishes has the sweet taste; the crustacea and the shellfish the salty or sour in addition to the sweet taste; none of them were bitter or hot. Most of them had the mild nature; seven of them were regarded as warm; four as cool; one as cold from the standpoint of the traditional medicine. The food-nature of seafoods was closely related with the medicinal effects on the human body. These seafoods were characteristically used in daily dietary life as well as the medical applications; used as the side-dishes rather than the main-dishes. The cooking methods of boiling, steaming, and baking were preferred to drying and stewing. The preservation methods favored were the fermentation, drying and salting. These cooking and preservation methods were believed to reflect the nature of the seafoods to manifest the medicinal effects.

This is a retrospective study on the patients with infection of the oral and maxillofacial region with the purpose of obtaining some useful data for diagnosis and treatment plan of that relatively common disease in dentistry. The used materials of study were 87 in total, including 52 male patients, 35 female patients who diagnosed and treated at the Department of the Dentistry in Hanyang Medical College Hospital for the period of Jan. 1990 to Dec. 1994. The author analyzed the distribution and incidence of sex, age, admission period, etiologic factors, etiologic teeth, treatment method of infections, pus culture, antibiotics sensibilities and medication. The result obtained as follows : 1. The developmental incidences by sex was superior in male by the ratio of 1.5 : 1 and the infection was most frequently occurred during the third decades(35.6%). 2. The number of admitted patients elevated in February, March, and April, and average of admission period was 9.8 days. 3. Main etiologic teeth showed on lower molar region in adult(63%) and upper molar region in primary dentition(46.1%). 4. Medications were administrated in all of the cases, and surgical incision and drainage were performed in 53% and extraction of the causative teeth were performed in 63.6% of all cases. 5. The most common involved fascial spaces were Buccal space(41.4%), Infraorbital space(27.6%), Submandibular space(16.1%),in order, and 9 cases(10.3%) were Ludwig's Angina. In 68.2% of the patients, and infection involved only one fascial space and in 21.8% of the patients, it involved to more fascial spaces. 6. The most causative organisms isolated from pus culture were Gram-positive facultative cocci(55.5%), and antibiotics sensitivities on the total isolated bacterial strains were exposed chloramphenicol(88.6%), Cephalothin(88.6%), Erythromycin(81.5%), Lincomycin(77.8%) in order, but it showed resistant on Gentamycin(58.3%), Tetracycline(56.5%), Methicillin(38.5%).

MPLS의 GSMP 인터페이스에 관한 연구

차영욱,김진년,백현규 安東大學校 工業技術硏究所 2001 공업기술연구논문집 Vol.8 No.1

계층 3의 라우팅과 계층 2의 레이블 스위칭 기술을 통합한 MPLS는 고속의 전달, 트래픽 엔지니어링 그리고 가상 사설망 서비스의 지원을 가능하게 한다. 레이블 스위치 및 제어기 사이에서 동작하는 GSMP 프로토콜을 연결, 구성, 장애, 성능관리 및 동기화 기능을 제공하는 개방형 인터페이스이다. 개방형 인터페이스는 다양한 융통성을 제공하는 반면에 전통적인 스위치-대-스위치 연결설정에 비하여 지연을 감수하여야 한다. GSMP 기반의 개방형 인터페이스에서 망 관리를 위한 SNMP에이전트는 레이블 스위치 또는 제어기에 탑재될 수 있다. 본 논문에서는 MPLS네트워크의 전달평면과 제어평면사이에 적용된 GSMP 인터페이스에서 병렬형 연결설정 방안과 망 관리 모델에 대하여 제안하였다. MPLS, which integrates routing of layer 3 and switching of layer 2, enables support of fast forwarding, traffic engineering and virtual private network services. GSMP is open interface, which provides connection, configuration, event and performance management and adjacency protocol between label switch and controller. The GSMP open interface separates control plane and transport plane. This separation allows flexibility in the network, but it suffers more setup delay than the traditional switch-by-switch connection setup. In the GSMP open interface, the functions of network management will be located either in controller or in label switch. This paper proposes parallel mechanism of connection establishment and network management model, in which the GSMP open interface is applied between control plane and transport plane of the MPLS network.

연구목적: 본 연구는 공황장애 환자들을 대상으로 성격요인과 방어기제 검사를 실시하였으며 우울 및 사회기능 정도를 측정하여 상관관계를 알아보았다. 방 법: 1997년 9월부터 1998년 8월까지 환자들중 공황장애로 진단된 35명을 대상으로 성격요인검사(Sixteen Personality Questionnaire 한국판) 및 방어기제검사(이화방어기제검사)를 시행하여 스텐점수(1-10)화 하였고, 우울증척도(Beck Depressive Inventory 한국판) 및 사회기능장애척도(Sheehan Disability 한국판)를 시행하였다. 결 과: 1) 개별항목 (1) 성격요인과 방어기제의 척도별 평균점수에서 정상보다 높거나(8점이상) 낮은(3점이하) 척도는 없었다. (2) 성격요인중 불안감이 높았고 자아강도, 신중성, 사변성은 낮은 점수를 보였다. (3) 방어기제중 신체화, 행동화의 점수가 높았고 유우머, 억제, 이타주의, 회피, 합리화는 낮은 점수를 보였다. (4) BDI의 평균점수는 18.25±9.97이었다. (5) SDS의 평균점수는 업무항목 4.88±3.11. 사회활동/오락활동항목 4.57±2.92였다. 2) 상관관계 (1) 성별간 비교에서 성격요인은 사변성, 죄책감을 방어기제는 허세, 부정, 수동공격, 투사를 남성 이 높게 보였다(p<0.05). (2) 연령증가는 성격요인중 낮은지능과 방어기제는 예견, 해리와 상관을 허세와 역상관을 보였다(p<0.05). (3) BDI 점수는 성격요인중 지능도, 자아강도, 도덕성, 죄책감, 통제력, 불안감등과 방어기 제중 해리, 신체화등과 유의미한 상관관계를 나타냈다(p<0.05). (4) 사회기능장애척도의 업무항목은 성격요인중 죄책감, 진보성, 불안감, 도덕성과 방어기제의 신 체화, 투사등과 유의미한 상관이 있었고, 사회/오락활동항목은 성격요인의 죄책감, 불안감과 방어기제중 허세, 투사 등과 유의미한 상관관계가 있는 것으로 나타났다(p<0.05). 3) BDI와 사회기능장애척도의 업무항목간에는 유의미한 상관관계가 있는 것으로 나타났다(p<0.05). 결 론: 공황장애 환자는 성격요인검사상 불안감이 높고 자아강도, 신중성, 사변성은 낮게 나타 났으며, 신체화 등의 신경증적 방어기제를 주로 사용하는 반면 유우머, 억제, 이타주의, 회피, 합리화의 방어기제는 적게 사용하는 것으로 나타났다. 증상의 강도와 관련이 있는 우울증상은 업무활동에 영향을 미쳐 이와 관련된 중등도의 사회기능의 장애를 초래하고 있는 것으로 보인다. Objectives : The purpose of this study was to evaluate the characteristics of personality factor and defense mechanism and relationship with depression and disability. Methods : Study subjects consisted of 35 panic disorder patients diagnosed with the criteria of DSM-Ⅳ. Data were collected through Sixteen Personality Factor Questionnaire, Ehwa Diagnostic Test of Defense Mechanism, Beck Depression Inventory and Sheehan Disability Scale. Statistics employed for the analyses were Pearson correlation and independent sample t-test. Results : In personality factors and defense mechanisms, there were no definitely abnormal range of scores. But, among personality factors, tension/anxiety factor scored high and unstableness/stableness, shyness/boldness and praxernia/atunia were in low range of score. In defense mechanism, somatization and acting-out scored high and humor, suppression, altruism, avoidance and rationalization scored low. The mean BDI score was 18.25±9.97. The mean score of SDS were 4.88±3.11 in work category and 4.57±2.92 in social/leasure category. Male patients were significantly correlated with guit-proneness and atuia in personality factor and passive-aggressiveness, projection, denial and show-off in defense mechanism, compared with female patients(p<0.05). The patients` age was correlated with low intelligence in persolity factor and dissociation and anticipation in defense mechanism. It was negatively correlated with show-off(p<0.05). The BDI score was correlated with low intelligence, superego, unstableness, self-conflict, high superego and atunia in personality factor and dissociation and somatization in defense mechanism(p<0.05). There was a significant relationship between BDI score and SDS work category(p<0.05). Conclusions: Panic disorder patients show high score of tension/anxiety factor and they frequently use neurotic defense style like somatization. The depressive symptom, which depends on symptom severity, appears to have influence on work category and to cause social disability.
