본 시험은 유기인계 살충제인 Terracur P입제 및 Lebaycid 입제와 유기염소계 살충제인 상감마입제$(\gamma-BHC 입제)$를 수면시용 하였을때 수도요해충인 이화명충, 끝 동매미충, 애멸구 및 흰둥멸구에 대한 동시방제가능성과 방제적기를 구명하고 약제간의 방제효과를 비교코저 실시하였다. 얻어진 시험결과는 다음과 같다. 1) 약제처리후 부화직후 이화명충 접종 시험에 있어서 상감마와 Terracur P는 높은 살충율을 보였으나 Lebaycid의 살충율은 낮았다. 約 $50\%$ 살충력 잔효일수에 있어서 상감마는 8-14日이었고 Terracur P는 6일간이었다. 2) 당초 계획된 방제적기에 관한 정보는 얻을 수 없었다. 즉 주어진 일간격이 좁아 유의한 차를 얻을 수 없었다. 3) 1,2화기 이화명충에 대한 방제효과는 Terracur P=상감마>Lebaycid의 순이었다. 4) Terracur P와 Lebaycid 입제의 처리는 끝동매미충의 방제효과가 좋았으나 상감마$(\gamma-BHC 입제)$의 방제효과는 기대할 수 없었다. 끝동매미충에 대한 Terracur P와 Lebaycid입제의 잔효력은 30일 이상이었다. 5) 애멸구와 흰등별구에 대한 시험은 충의 서식밀도가 낮기 때문에 약제간 방제효과를 얻을 수 없었다. 6) 공시약제중 Terracur P와 Lebaycidd입제는 이화명충과 끌동매미충의 동시방제제로서 사용할 수 있을 것 같다. This experiment was conducted to find out the simultaneous control effect of granulated insecticides on the several major rice insect pests in Korea. The granulated insecticides used were Terracur P$5\%$ (one of the phosphoric insecticides), Lebaycid $5\%$, and Sang-gamma (gamma-BHC) $6\%$. Those insecticides were broadcasted by hand on the paddy field at the ratio of 3kg. in June and 4kg. in August per 10 a, and the date of insecticidal application was based on the maximum moth occurrence of the rice stem borer in 1969. The rice insect pests tested in this study were rice stem borer (Chilo suppressalis W.), green rice leafhopper (Nephotettix bipunctatus cincticeps U.), smiller brown planthopper (Laodelphax striatellus F.), and white back planthopper (Sogotella furcifera H.). For the study of residual effectiveness of the insecticides, the rice stem borer larvae just hatched from the eggs were installed on the sheath of rice plants collected from the paddy field after insecticidal treatment, and the mortality was made at 48 hours after installation. High mortality was observed in Terracur P and Sang-gamma treatments and low mortality in Lebaycid treatment. The duration of residual effects giving about 50% mortality was about 14 days in Sang-gamma and about 6 days in Terracur P treatments. The study on the effectiveness of the insecticides to the rice stem borer in the paddy field was made by the number of dead blades and white heads of the rice plants injured by the larvae, and the number of survival larvae in the straws after crop harvest. The order of insecticidal effectiveness to the rice stem borer was Terracur P=Sang-gamm>Lebaycid. The study on the effectiveness of the insecticides to the leafhoppers and planthoppers in the paddy field was made by the population density by sweeping (5 times) at the given day intervals after treatments. Terracur P was highly effective for the control of the green rice leafhoppers and Lebaycid was moderately effective, but Sang-gamma seemed not to be effective. The effectiveness of the insecticides tested to the planthoppers was not clear, and it seemed to related with the low insect population density. Study on the determination of proper timing of insecticidal application was not also made clear, and it seemed to be short in the range of day intervals in the insecticidal application. For the study on the control effects of the rice insect pests, rice yield per 100 hills per plot was observed. There was no statistically significant difference among the treatments in rice yields, but the order of yield (Terracur P>Sang-gamma>Lebaycid>Control) was paralleled with the tends of control effects above mentioned. In a view point of simultaneous control of the rice stem borers and green rice leafhoppers by the application of granulated insecticides, Terracur P and Lebaycid were more effective than Sang-gamma which have been used.

목적 : 2002년 말 중국에서 SARS가 발생한 이후 국내에서도 2003년 10월까지 총 3명의 추정환자, 17명의 의심환자가 보고되었다. 향후 추가적인 SARS의 유행이 우려되는 상황에서, 그간의 SARS 환자 진료에 있어서의 실질적인 준비사항, 진료 현황 등에 대한 조사를 통해 문제점을 파악하여, 향후 더 나은 대비가 될 수 있도록 개선점을 제시하고자 하였다. 재료 및 방법 : SARS로 의심되는 환자를 진료 경험이 있는 병원의료진을 대상으로 2003년 10월에 설문조사를 실시하였다. 설문에는 SARS 환자 진료 시의 실질적인 조치, 진료 현황, 병실, 응급실 및 외래에서의 격리 시설과 준비사항, 보건당국의 관리와 지원에 관한 사항을 포함하였다. 결과 : 대상이 되는 22개 병원 중 17개(17/22, 77.2%) 병원이 설문에 응하였다. SARS 환자를 위한 격리실은 응급실, 외래, 일반병실 및 중환자실에서 각각 9개(9/17, 52.9%), 5개(5/17, 29.4%), 15개(15/16, 93.7%), 4개(4/16, 25%) 병원에서 음압처리가 되어있지 않은 일인실 혹은 다인실이 사용되었고, 1개(1/16, 6.3%) 병원에서만 일반병실에서 음압격리실이 운영되었다. 입원환자의 진찰 시 개인보호구의 착용은 거의 모든 의료기관에서 이루어졌다. 보건당국에서 SARS지정병원의 시설 등을 사전에 확인한 곳은 1곳(1/12, 8.3%)이였고, 14개 병원(14/15, 93.3%)에서는 보건당국에 의뢰한 검사결과를 통하 받지 못하였다. 결론 : 의료기관에서 SARS 환자용 격리실뿐만 아니라 기존의 격리실 설비 등이 미흡하였으며, 특히 중환자실 및 외래의 준비가 더욱 부족하였다. 보건당국의 의료기관에 대한 종합적인 지원이 부족하였고, 병원과의 원활한 연계가 잘 이루어지지 않았다. SARS 만이 아닌 격리를 필요로 하는 질환의 적절한 진료를 위해 향후 병원 시설의 정비와 정부차원에서의 보다 구체적이고 실질적인 대책마련이 필요하다. Background : There was an worldwide outbreak of the Severe Acute Respiratory Syndrome (SARS) originated from China in late 2002. During that period three cases of suspected SARS and 17 cases of probable SARS were reported in Korea. With the concerns about the reemergence of SARS-coV transmission, it is important to be prepared for any possibility. So, this study is aimed to analysis the past measures in managing SARS and propose the amendatory plans to improve the preparedness. Materials & Methods : Questionnaires were collected among clinicians with any experience in managing the probable or suspected SARS cases in Oct. 2003. 17 out of 22 hospitals responded to the questionnaire. The contents in the questionnaire were practical activities, personal equipments, response plans, isolation facilities in emergency centers, outpatient clinics, general wards and intensive care units, and relationship with the public health department. Results : The dedicated isolation rooms in emergency centers, outpatient clinics, general wards, and intensive care units were prepared in 9 (9/17, 52.9%), 5 (5/17, 29.4%), 15 (15/16, 93.7%), and 4 (4/16, 25.0%) hospitals, respectively. Except for one hospital that newly made negative pressure room for SARS, single or multi-bed rooms without airborne infection control were used in all the other hospitals. The personal precaution principles were kept quite well in general wards. Before the designation of SARS hospital by the public health department prior evalution to see if the hospital was suitable for managing SARS was conducted in only 1 (1/12, 8.3%) hospital. The results of laboratory diagnosis were reported back in 1 (1/15, 6.6%) hospital. Conclusions : The isolation facilities which can control airborne infection were almost deficient not only for SARS but also for other respiratory transmissible diseases. For the infection control of transmissible diseases including SARS, more investment is needed on medical facilities and comprehensive support from the public health department required.

송혜원,김홍,박상욱,엄용빈,김종배,박성언,김근희 THE KOREAN SOCIETY FOR BIOMEDICAL LABORATORY SCINE 1999 Journal of biomedical laboratory sciences Vol.5 No.2
라임병의 원인균인 Borrelia burgdorferi에 대하여 각 균종의 표준균주와 진드기에서 추출한 DNA를 template로 PCR을 실시한 후 그 증폭산물을 Alu I으로 처리한 restriction fragment length polymorphism (RFLP) 방법으로 각 균종의 연관성을 조사하고자 하였다. 표준균주로 RFLP를 실시한 결과 B. burgdorferi sensu stricto와 B. garinii의 RFLP 형태 (50 bp, 70 bp, 150 bp)가 유사하였으며 B.afzelii에서는 다른 RFLP형태 (50bp, 110bp, 150 bp)를 관찰하였다. 그 중 B. afzelii KK-1과 B. garinii HP1은 새로운 RFLP 형태를 보여 B. afzelii와 B. garinii는 각각 2 types의 subgroup으로 분류할 수 있었다. 진드기 DNA에서 는 B. afzelii를 포함한 각 균종에 대하여 모두 유사한 RFLP 형태를 보였는데, 진드기 DNA에서 확인된 B. afzelii는 KK-1과 같은 군에 속하는 것으로 사료되었다. For the classification of B. burgdorferi sensu lato strains, PCR-restriction fragment length polymorphism (RFLP) analysis was performed. PCR was carried out with B. burgdorferi sensu lato specific primer set (BB uni set), and amplicons of 470-bp DNA were digested with Alu I. The Alu I restriction polymorphism of the amplicons provided a useful tool for identifying B. burgdorferi sensu lato strains. Both amplicons from B. burgdorferi sensu stricto and B. garinii except HP1 strain showed identical RFLP pattern (50 bp, 70 bp, and 150 bp), but amplicons from B. afzelii and B. garinii showed two types of subgroups, respectively. The result of PCR-RFLP using extracted DNAs from ticks was similar to those patterns of B. burgdorferi species including B. afzelii.

송재훈,최승원,박수길,고윤석,서철원,이규형,이정신,문희법,김상희 대한화학요법학회 1991 대한화학요법학회지 Vol.9 No.2
To evaluate the efficacy of the single agent therapy for the initial management of fever in neutropenic patients, we conducted a prospective randomized trial comparing imipenem/cilastatin alone with a combination of piperacillin and amikacin. Among 40 evauable episodes of fever, stratum A(hematologic malignancy, n=30) consisted of 15 imipenem group and 15 piperacillin plus amikacin group and stratum B consisted of 10 cases with solid tumor. There was no difference in age, sex, duration of neutropenia, initial granulocyte count and number of cases with severe neutropenia(<100/㎣) between two groups. Overall response rate to imipenem was higher(86.6%) than combination therapy group(53.5%) in stratum A, but statistical difference was not found. Overall response rate to imipenem in solid tumor was 100% whereas to combination therapy group was 40%. There was no serious toxicity on imipenem use. We conclude that imipenem monotherapy could be an effective & safe empirical therapy in the treatment of febrile neutropenic patients.

송진영,김창억,김성욱,우흥정,김미란,이규만,이란,장미화,정희진,김우주 대한화학요법학회 2001 대한화학요법학회지 Vol.19 No.4
목적 : 한강성심병원에서는 2000년 3월 반코마이신내성 장구균이 처음 분리되어, 원내전파를 막기 위한 노력을 하였으나, 분리가 지속되었다. 따라서 이에 대한 좀더 자세하고 객관적인 자료를 얻기 위해 본원에서 분리된 반코마이신내성 장구균에 대한 임상분자 역학적 연구를 시행하게 되었다. 방법 : 2000년 3월부터 2001년 2월까지 한림대학교 한강성심병원에서 분리된 장구균을 대상으로 디스크 확산법, 최소발육억제 농도등의 측정을 통해 반코마이신 내성여부를 확인하였으며, 반코마이신내성 장구균을 대상으로 PFGE를 시행하여 형별 분석을 하였다. 결과 : 분리된 균주는 총 32균주로 모두 E. faecium이었다. 항생제 내성 검사 결과 모두 Van A형이었다. PFGE 결과 1a형이 8검체, 1b형이 5검체, 2a형이 4검체, 2b형이 4검체, 3a형이 2검체, 3b형이 5검체였고, 그 외 4, 5, 6형이 각각 1검체씩이었다. 총 32균주 중 56%(18/32)의 균주가 같은 시기, 같은 병실에서 동일한 PFGE 형을 보이면서 분리되었다. 결론 : 반코마이신내성 장구균의 PFGE 분석 결과 여러 종류의 반코마이신내성 장구균이 유행하였음을 알 수 있다. 그러나 같은 기간, 같은 병실에서 분리된 균주의 PFGE 형이 같은 것이 상당수 있었다. 이는 반코마이신내성 장구균의 원내 전파가 있었음을 의미한다. 따라서 반코마이신내성 장구균의 전파의 발생 및 전파 방지를 위해서는 보다 효과적인 감염관리 활동이 필요할 것으로 생각된다. Background: Vancomycin-resistant enterococci(VRE) have been a rising problem worldwide. In March 2000, VRE was first isolated from a patient in Hangang Sacred Heart hospital. Although efforts to prevent transmission of VRE were performed, isolations continued. So molecular epidemiological study of VRE was done. Method : The minimal inhibitory concentration(MIC) to vancomycin and teicoplanin, and pulsed field gel electrophoresis(PFGE) pattern of VRE isolated from March 2000 to February 2001 were evaluated. Results : 32 VRE were isolated. All of the VRE were Enterococcus faecium and showed Van A resistance phenotype. We found out that a significant number of VRE isolated during same period and in same room, were same PFGE patterns. (18 cases/ 32 isolates= 56%) Conclusion: This study demonstrated the spread of VRE of same PFGE patterns. It suggests the nosocomial spreads of VRE.

안희정,안복주,·김도현,·안영섭,·김영국,박춘근,이상원,·박충범·차선우,·송범헌, 忠北大學校 農業科學硏究所 2015 農業科學硏究 Vol.31 No.1
This study was conducted to have basic and applied informations to establish the cultivation method and to improve the cultivation techniques of Angelica gigas Nakai through investigating the rates of germination and seedling establishment with treatment of plant growth regulator and seed priming. The germination rates of round shape seed were about 0.3~12% higher than those of parallel shape. The germination rates with different storage durations were increased at the level of 25oC and 4oC with the storage days, while they were clearly higher at -20oC compared to those at 4oC and 25oC without the storage durations. With the results of germination rates with treating of plant growth regulator and seed priming, their rates with the round shape seeds were comparatively higher about 6% than those with parallel shape seed and they were increased with increasing of the storage durations. The germination rates were generally appeared higher with GA3 than did those with seed priming. The highest germination rate was appeared at 50 ppm GA3 of plant growth regulator and at -0.5 MPa PEG6000 of seed priming. The germination rates?ㅤ ?ㅤ of Angelica gigas were different with different temperature, storage durations and the treatments of plant growth regulator and seed priming. These results could be used according to different cultivating conditions.
