In Vitro Antiviral Activity of Ribavirin Against Severe Fever with Thrombocytopenia Syndrome Virus Myung Jin LEE1, Kye-Hyung KIM1, Jongyoun YI2, SuJin CHOI1, Chung-Jong KIM1, Nak- Hyun KIM1, Kyoung-Ho SONG1, Pyoeng Gyun CHOI1, Ji-Hwan BANG1, Wan Beom PARK1, Eu Suk KIM1, Sang-Won PARK1, Hong Bin KIM1, Nam Joong KIM1, Myoung- Don OH1 Seoul National University College of Medicine, Korea1, Pusan National University School of Medicine, Korea2 Background: Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease caused by a novel Bunyavirus, severe fever with thrombocytopenia syndrome virus (SFTSV). No effective antiviral therapy is proven yet, but clinical use of ribavirin (RBV) has been tried. We investigated the antiviral effect of RBV against SFTSV in vitro. Methods: To test for cytotoxicity of RBV, Vero cells were treated with different concentrations of RBV (3.90 to 500 μg/mL, two-fold dilution) and analyzed by cell viability MTS assay 48h post-infection. To determine antiviral activity of RBV against SFTSV, Vero cells were infected with SFTSV strain Gangwon/Korea/2012 at 100 TCID50 (50% tissue culture infective dose) per well in a 96-well plate, and RBV was added at the concentrations showing no or minimal cytotoxicity. Viral RNAs were extracted from the culture supernatants and quantifi ed using one-step real-time reverse transcription- PCR to amplify the partial large segment of SFTSV. Statistical analysis was done by one-way ANOVA with Tukey`s post hoc test. Results: Cytotoxicity due to RBV was not observed at RBV concentration =31.3 μg/ mL. Viral RNAs at 24h post-RBV treatment were reduced with increasing RBV concentrations (1-32 μg/mL), compared with those of mock-treated cells (P <0.01, Figure). Half maximal inhibitory concentration (IC50) of RBV was 3.69 μg/mL at 24h post-RBV treatment. Conclusions: Our study shows that RBV has antiviral effect against SFTSV in a dose-dependent manner. Further studies are required to evaluate the effi cacy of RBV in SFTS.

대구시의 염색폐수처리장 폐수 및 처리장 주변의 토양과 물에서 반응성 염료인 Cibacron Brilliant Red 3B-A(CBR), Reactive Orange 16(RO), Reactive Black 5(RB)에 탈색능을 보이는 12종의 균을 분리하고 이들 균 중에서 본 실험에 사용한 CBR, RO, RB5 염료 모두에 약 90% 이상의 높은 탈색율을 나타낸 CBR2균을 선별하였다. 선별된 CBR2균의 특성 및 염료분해특성을 조사하였다. CBR2균은 그람 음성, 무아포, 간균으로 운동성이 있으며, 염농도 5%, 온도 50℃에서도 생육이 가능하였다. CBR2균의 생육 및 염료의 탈색에 미치는 pH의 영향을 조사한 결과, pH 5.0에서 9.0까지 고른 균 성장과 탈색율을 나타내었으며 특히 pH 7.0에서 최고의 균 성장 및 염료 탈색율을 나타내었다. 온도별 균의 생육 및 염료의 탈색율을 조사한 결과 30℃에서 가장 높은 균 성장 및 탈색율을 나타내었다. 산소량에 따른 균의 생육 및 염료의 탈색율을 조사한 결과, 산소량이 많을수록 균의 생육이 좋았으며, 염료의 탈색율에 있어서도 CBR 염료의 경우는 산소량에 비례해서 탈색율이 좋았으나, RO와 RB5 염료의 경우는 산소량이 가장 많은 2ml양의 배양에서 보다 상대적으로 산소량이 적은 4ml양의 배양에서 가장 높은 탈색율을 보였다. Twelve strains, which were exhibited abilities of decolorizationto the reactive dyes, Cibacron Brilliant Red 3B-A(CBR) , Reactive Orange 16(RO) and Reactive Black 5(RB5) , were isolated from the samples of waste waterof the dye textile factories and the samples of soil and water around them. Amongthem one stain, CBR2 was selected because of the higest decolorization rateto the reactive dyes, CBR, RO and RB5 with more than 90% of decolorizationrate. The characteristics of reactive dye-degrading microorganism CBR2 andits decolorization abilities to reactive dyes were investigated. This CBR2 wasGram negative and non-spore forming rod. This organism has motility and ispossible to grow even in 5% of sodium chloride solution and at such temperatueof 50℃ In the pH 5.0 to 9.0, growth rate of the isolate and decolorizationrate to reactive dyes by CBR2 were exhibited almost similar rates. However,among those pH of media the most growth and decolorization rates were appearedat pH 7.0. On the temperature effects to growth rates of CBR2 and decolorizationrate by this organism, the most growth and decolorization rates were at tempera-ture of 30℃. More oxygen volumes in test tubes enhanced generally the growthrate of this organism. However, the decolorization rate of CBR dye by CBR2was higher according to oxygen volume increased in the media but the decoloriza-tion rates of RO and RB5 dyes in 2m1 volume of culture media were rather decrea-sed than that of 4ml volume of culture media where oxygen volume is lowerthan that of 2ml volum of culture media.

Background : Upper respiratory infections (URIs) are common benign illnesses that are associated with significant economic burden, adverse effects of medications, and antimicrobial resistance. These effects have been evaluated chiefly at the tertiary health care centers. The purpose of this study was to investigate the prescribing habits, including antibiotic use, for the management of URIs among the primary care physicians. Methods : Between July and August 2006, 23 medical students visited 122 clinics of primary care physicians for the management of simulated common cold. They were instructed to present symptoms that simulated common cold; clear rhinorrhea and nasal stuffiness that lasted for 3 days, and neither was accompanied with fever nor myalgia. Results : The physicians' specialties were as follows: 43 were general internists; 40, otolaryngologists; 23, general practitioners; 15, family practitioners; and 1, pediatrician. The mean number of prescribed oral medications was 4.71 (S.D.±0.951). Glucocorticoids were prescribed in 10 (8.2%) clinics. Antibiotics were prescribed in 50 (41.0%) clinics - cephalosporins in 17, amoxicillin-clavulanate in 16, amoxicillin in 8, fluoroquinolones in 5, macrolides in 3, and trimethoprim-sulfamethoxazole in 1 clinic. There was no difference in the rates of antibiotic prescription among the specialties. Injections were recommended in 32 (26.4%) clinics. With the exception of chest X-ray recommended in 1 clinic, no laboratory or radiologic evaluation was performed. Conclusion : The antibiotic prescription rate observed in this study is lower than those of the previous studies. Since diagnostic tests are seldom performed, diagnostic ambiguity might be a key cause for the overuse of antibiotics in the management of URI. The reasons for the high rates of prescription of parenteral medications need to be evaluated. 목적 : 상기도 감염은 매우 흔한 질환으로 개개인으로 보면 중요하지 않은 병이나 국가 전체로 보면 비용, 부작용, 항균제 내성에 미치는 영향이 더 문제가 되는 병이다. 이런 영향에 대한 연구가 주로 3차 병원에서만 되므로, 3차 병원에 도착하기 전까지 받은 치료 내역이 연구 결과에 큰 영향을 미칠 수 있지만, 국내에서는 의약분업 후로는 의원에서 감기 처방에 대한 조사가 없어 현재 진료 상황을 알 수가 없다. 이에 의약분업 이후, 1차 의료에 종사하는 의원들을 대상으로 코감기에 관련된 진단의 다양성, 주사제의 사용, 항균제 사용에 대해 조사를 하였다. 재료 및 방법 : 2006년 7월과 8월에 걸쳐 서울, 경기, 인천에 개업하고 있는 일반의, 내과의, 이비인후과의, 가정의를 대상으로 122개 의원을 조사 하였다. 23명의 의과대학생들이 코감기 환자로 모의를 하여 개원의들의 진찰을 받은 후, 진단과 처방을 분석하였다. 코감기 증상은, 3일간 지속한 콧물과 코막힘을 주소로 했고, 발열과 오한은 없었으며, 목아픔과 기침은 약간 있는 정도로 하였다. 결과 : 조사한 의원에서 코감기에 사용한 경구 약제 수는 평균 4.71 (SD±0.951), 과별 차이는 없었다(P=0.99 by chi-square test). 부신피질호르몬은 10개(8.2%) 의원에서 처방하였다. 항균제는 50개(41.0%) 의원에서 처방하였으며, 세팔로스포린 17건, Augmentin 16건, amoxicillin (7) 또는 bacampicillin (1) 8건, 퀴놀론 5건, macrolide 3건, trimethoprim-sulfamethoxazole 1건이 었다. 과별로는 내과 34.9%, 이비인후과 52.5%, 가정의학과 33.3%, 일반외과 39.1%, 소아과 0%였고 통계적 의미는 없었다(P=0.41 by chi-square test). 주사를 권한 경우는 32 (26.4%)예였다. X-선 검사를 권유받은 1건 외에는 검사를 권유받지 않았다. 결론 : 이전 보고보다는 감기에서 항균제 사용률은 낮았으며, 진단을 하기 위한 검사가 적어 진단의 불분명을 극복하기 위한 것도 항균제 남용의 한 원인으로 생각된다. 주사제 처방률도 높은 듯하며 이는 빨리 증상이 호전되지 않을 때 병원을 바꾸는 환자들의 행위에 대한 반응일 가능성이 있으며, 항균제 사용 역시 빠른 증상 호전을 위한 것이어서, 환자의 행동 양상에 대한 조사가 필요하다.

Background : Exccssive sweating of the facial, Palms, axilla and soles, is a psychologically and occupationally distressing and sometimes disabling condition. VideoUassisted thoracoscopic surgery (VATS) is now mostly performed for treating of the facial, palmar and axillary hyperhidorsis. This study was designed to evaluate the results and complication of sympathicotomy of the primary hyperhidrosis. Material and methods : From June 1999 to May 2002, 55 patients ( 30 males and 25 females ) suffering from primary hyperhidirosis were operated. The mean age of patients was 24.0±6.0 years. Bilateral thoracoscopic sympathicotomy was resected the only T2, T2 & T3, onlY T3, T3 & T4 and T2, T3 & T4. The mean follow up period was 18±6.5 months. Results : Mean operation time was 61.2+25.0 minutes and the mean elevation of palmar temperature after sympathicotomy was 1.13±0.2℃. There were no operative deaths but some complication existed : 42 patients (76%) complained the compensatory hyperhidrosis, and 5 patients was developed the postoperative pneumothorax. Sweating decreased in 43% of the planter hyperhidrosis. Conclusion : Most of the patients were satisfied with the postoperative results of the thoracoscopic sympathicotoiny. We conclude that thoracoscopic sympathicotomy is a simple, safe and effective technique in primary hvPcrhidrosis, but satisfaction has been decreased by the compensatory hyperhidrosis; therefore, it is important to thoroughly explain the compensatory sweating. We recommend that the less extent of sympathicotomy decrease the incidence of compensatory hyperhidrosis.

These experiments were carried out to detect autoantibodies to zona pellucida in sera from infertile women using indirect ELISA and their effect on in vitro fertilization of mouse ova as a biological test. By indirect ELISA method, 9 of 95 serum samples (9.5%) from infertile women gave positive reaction, whereas all of 16 samples from fertile women and men were negative. These sera were then used in in vitro fertilization of mouse ova. The fertilization rates (15.9%) of eggs treated with positive sera were significantly lower than those (51.9%-71.2%) of eggs treated with control sera. From those results it could be said that the antibodies to zona pellucida are responsible for infertility in fertile women. presumably by preventing sperm attachment and penetration at fertilization.

본 연구는 동화를 활용한 통합활동 중심의 사회적 유능성 증진 프로그램이 언어적으로 지체된 유아의 사회적 유능성에 어떠한 변화를 가져오는지를 알아보고자 하였다. 연구대상은 부산대학교 어린이상담실에 의뢰된 6-7세 유아들로, 유아들의 발달적 요구와 3회까지 관찰된 유아의 행동 특성 및 초기 면담 결과를 근거로 유아의 중재목표행동이 선정되었다. 프로그램 내용 및 운영은 동화 듣기와 동극 하기, 작업활동, 음률활동, 게임, 신체 활동 등의 통합활동 중심으로 주 1회, 총 15회 동안 두 명의 중재교사, 관찰자 및 부모교육 담당자에 의해 수행되었다. 연구 결과 동화를 활용한 통합활동 중심의 사회적 능력 증진 프로그램은 유아에 따라 다소 차이는 있었으나 중재 목표 행동인 또래에게 상호작용 시도하기, 또래와의 문제상황에 대처하기 및 교사의 지시 따르기를 증진시키는 효과가 있었다. This study examined the effectiveness of a social competence program for language delayed children. The Hierarchical Model of Social Competence by Guralnick(1992) provided the framework of the social competence program. The activities of the program were consisted of fairy tale integrate activities, like dramatization, art and occupation activities, physical activities and game etc. Subjects were 3 boys aged 6-7 years, with language delays. The program ran for 15 sessions. Two intervention teachers, two observers and one parent group leader implemented each session for 90 minutes once a week cooperatively. The target behaviors of the subjects were to initiate interactions with others, cope with problem situations with peers and follow teacher's suggestions. Data on the frequencies of target behaviors and the behavior episodes related with target behaviors during each session were analyzed. Although there were some individual differences in the changes of target behaviors, most of children became to be more sociable. The implications for developing social competence programs for children with language delays were discussed.

Agents have become very popular in the last six or so years. Agent technology has a large part to play in facilitating general information retrieval on the Internet. More recently, the capabilities of agents have been applied to Electronic Commerce. To be univrersal Electronic Commerce, Customer buys goods by internet and choose the providers widely. but It's came into the question that haw can contact provider for cheap goods. It says that Electronic Commerce Agent. Among Electronic Commerce Agents, if agent supply goods information for- cost, the agent be called Comparison Shopping Agents. In this paper, we designed and implemented a Comparison Shopping Agent for music disk searching. Agents has insufficiencies Agents can't retrieve information in web page is made by CGI program. If Agents want to get the information for Comparison Shopping Agent, they can't execute the work. Because shopping-malls are made by CGI program. In this paper, we propose that usage of FORM-tag for a local database.
