Objective: Occupational medicine specialists in the Busan, Ulsan and Kyung-Nam areas established an area-based occupational disease surveillance system and used this system to collected case information for the purpose of preventing occupational diseases Methods: l l hospital participated in this system. The authors selected five main diseases, which were hand-arm vibration syndrome (HAVS), work-related musculoskeletal disorder (WRMSD), occupational asthma, occupational skin disease and occupational and occupational lung cancer and established their case definitions. All cases were reported on the web, and real time analysis was conducted. Results: Between April 2001 and April 2003, 192 cases of HAVS, 118 cases of WRMSD, 33 cases of occupational asthma, 17 cases of occupational skin disease and 17 cases of occupational lung cancer (for a total of 377 cases of these five main diseases) were reported. most of the HAVS cases came from shipbuilding, and 172 of them (92.7%) were associated with grinding. Of the four main types of WRMSD, carpal tunnel syndrome (CTS) was the most prevalent with 46 cases and shipbuilding was also the main industry involved (83.9%). The ergonomic risk factors involved mainly associated with the hand. In 19 (57.6%) and 4 (12.1%) cases of occupational asthma, the agents involved. The causative agents of occupational lung cancer included Cr, welding fume, PAH, Ni, etc. 10(58.8%) of the cases were diagnosed as squamous cell carcinoma and 5(29.4%) as adenoma. Conclusion: This result showed that an area-based occupational disease surveillance system might provide an effective method of evaluating the prevalence of such diseases, however the Busan, Ulsan and Kyung-Nam provinces are too large to be treated as individual areas. Therefore, the authors suggest that each province should establish its own surveillance system.

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.

A multiplex polymerase chain reaction (PCR) method was developed to simultaneously detect 3 events of genetically modified (GM) maize. The event-specific primers were used to discriminate the following 3 events of GM maize (DAS-59122-7, TC6275, and MIR604) using multiplex PCR method. The zein gene was used as an endogenous maize reference gene in the multiplex PCR detection. The primer pair Zein-F/R producing a 99 bp amplicon was used to amplify the zein gene. The primer JI-Das-F1/R1 for DAS-59122-7, JI-TC6275-F3/R3 for TC6275, and JI-MIR F1/R1 for MIR604 yielded an amplicon of 130, 162, and 197 bp, respectively. The detection limit of multiplex PCR was 1% for DAS-59122-7, TC6275, and MIR604 for one reaction.

During the past two years(1999-2000), the antimicrobial susceptibility tests for the major pathogenic bacteria isolated from the respiratory or digestive organs of the diseased pigs in Chungchong area have been carried out. Total of 88 strains in seven species were isolated from the respiratory lesions of the diseased pigs during the periods, and the major isolates were in order of P. multocida(27.3%), Staphylococcus spp.(20.4%), Streptococcus spp.(15.9%), E. coli(12.5%), B. bronchiseptica(11.4%), Haemophilus spp.(10.2%) and A. pleuroneumoniae(2.3%). From the fecal specimens of the pigs with diarrhoea, total of 146 strains in five species were isolated in order of E. coli(59.6%), Salmonella spp.(17.8%), Campylobacter spp.(14.4%), Streptococcus spp.(5.5%) and Clostridium spp.(2.7%). The isolates were tested the susceptibility for 30 kinds of antibiotics. Among the isolates from the swine repiratory lesions, P. multocida revealed over 71% of susceptibility to ciprofloxacin(CIP), enrofloxacin(EF), tylosine(TL) and norfloxacin(NOR). B. bronchiseptica showed over 70% susceptibility to CIP, EF, linco-spectin(LS) and NOR, and Haemophilus spp. over 78% of susceptibility to AN, CIP, EF and NOR. The isolates of Streptococcus spp. revealed over 80% susceptibility to CIP and EF, and Staphylococcus spp. over 78% of high susceptibility to amikacin(AN), cephalosporin(CP) and CIP. .In general, most of isolates were highly resistant to ampicillin(AM), bacitracin(B), ceftiofer(CT), chlorampenicol(C), colistin(CL), erythromycin(E), nalidixic acid(NA), novobiocin(NB), oxacillin(OX), penicillin G(P), polymyxin B(PB) and vancomycin(VA). Of the isolates from the pigs with diarrhoea, over 76% of E. coli isolates showed the high susceptibility to AN, LS and N. Salmonella spp. revealed over 71% of susceptibility to CT, CIP, EF, LS and NOR, and Campylobacter spp., over 76% of susceptibility to CT ,CIP, EF, GM, LS and TL. Higher susceptibility were observed CIP, LS, NOR and TL with Streptococcus spp. and AN, CIP, EF and LS with Clostridium spp.. Most of the isolates showed the higher resistance to B, CL, L, N, NB, OX, P, PB Te and VA. The MIC range of the major isolates for AN, CIP, NOR, LS FM and GM showing the relatively high sensitivity were measured. Compared with other drugs, CIP and LS showed the lower MIC of ≤0.06∼128 ㎍/㎖ and ≤0.06∼≥512 ㎍/㎖, respectively.

This study investigated mean airborne CO concention of 15 workplaces, suspected of CO exposure and conducted self-reported questionnaire completion and indirect COHb concentration measure using Micro II Smokerlyzer to healthy 702 adult subjects from 1999 May to 1999 September in order to find a relation of CO exposure and occupational factors, socioeconomic factors, and health related behaviors and confirm the related conditions in the screening test for CO exposure. The results of this study were summarized as follows : 1. In the CO exposed and non exposed group, COHb concentrations of the smokers were 2.55±0.96% and 2.21±0.97% and that got a statistically significant difference, There were not statistically significant differences in the age and total smoking index. Passed times after the last smoking, Working time/day, and working duration were statistically significant difference (p〈0.05). 2. In the CO exposed and non exposed group, COHb concentrations of non-smoking group were 0.94±0.35% and 0.68±0.47% and that got a statistically significant difference. There were not statistically significant differences in the age and working duration but Working time/day was a statistically significant difference(p〈0.05). 3. In the CO exposed group, r-square of multiple regression of the smokers was 38.5 % and passed time after the last smoking, working time/day, and job category were statistically significant differences (p〈0.05). And r-square in the CO non-exposed group was 38.3 % and age, passed time after the last smoking, and total smoking index were statistically significant difference. 4. In the CO exposed group, r-square of multiple repression of the non-smokers was 66.3% and job category and airborne CO concentration were statistically significant differences(p〈0.05). But r-square of non-smokers in the CO non-exposed group was 1.0% and there was not a statistically significant difference(p〈0.05). 5. In the smokers of CO exposed and non exposed groups, relation of COHb concentration and passed time after the last smoking was expressed as exponential function, Y = 2.9182e-0.0083x and r-square of this function was 37.4%. Therefore it was more than 150 minutes that passed time after the last smoking was when COHb concentrations were measured as less than 1%. In conclusion, variable, that was statistically significant to COHb concentraion in the both CO exposed and non-exposed smokers, was a passed time after the last smoking. We suggest that you have to restrict the smoking of smokers at least 150 minutes in the exposed and non exposed group before COHb concentration measure in order to exclude smoking effects

목적 : 본 연구는 수근관 증후군의 발생위험이 높은 작업형태에 종사하는 상지 단순반복작업근로자로서 육류 및 어류 가공 사업장과 목재소 근로자에서 근전도검사를 이용하여 수근관 증후군의 유병률을 조사하고자 하였다. 방법 : 상지 단순반복작업근로자로서 육류 및 어류 가공 사업장 근로자 69명과 목재소 근로자 17명을 실험군으로, 관리직, 경리, 경비등 상지의 단순반복작업이 없는 근로자 28명을 대조군으로 선정하여, 작업적 및 병력조사, 이학적 검사와 근전도검사를 통해 수근관 증후군의 유병률을 조사하였다. 결과 : 수근관 증후군의 유병률은 육류 및 어류 가공 사업장과 목재소에서 각각 26.09 % (18명)와 29.41 %(5명)로 조사되었으며, 육류 및 어류가공사업장과 목재소 근로자를 '7년 이상과 미만의 작업기간'으로 층화하여 비교한 결과 '상지부위의 통증 호소 유무', 'Visual Analogue Scale(VAS: 총 10점) 4점 이상 여부', 'Tinel teat 양성 유무', 'Phalen test 양성 유무'는 모두 단기 작업근로자군에서 양성의 빈도가 증가되었고 '수근관 증후군 유무'는 장기작업근로자군에서 양성의 빈도가 증가되었다. 결론 : 육류 및 어류 가공 사업장과 목재소의 수근관 증후군 유병률은 각각 26.09 %와 29.41 %로 육류 및 어류 가공 사업장과 목재소는 1996년 OSHA가 지정한 바와 같이 위험한 작업요인이 있는 작업장으로 분류하여 관리되어야 할 것으로 생각된다. Objectives : This study was carried out to survey on the prevalence of Carpal Tunnel Syndrome(CTS) in high risk jobs(meat and fish processing plant and wood plant), by application of Nerve Conduction Study(NCS), a confirmatory diagnostic method. Methods : Experimental group was 69 workers sampled from meat and fish processing plants and 17 workers sampled from wood plants, who were simple, repetitive workers using upper extremities and control group was 28 workers sampled from managers, secretaries and keepers. All employees were examined through work history, physical examination and NCS. Results : 18 workers(26.09%) in meat and fish processing plants, and 5 workers(29.41%) in wood plants had compatible findings to NIOSH diagnostic criteria for CTS. The experimental group had more symptoms (complaint of upper extremities, Visual Analogue Scale ≥4(VAS: total 10 point)), signs(Tinel and Phalen test) and prevalence of CTS than control group(p<0.05). The prevalence of symptoms and signs were higher in short term workers(<7 years), but the prevalence of CTS was higher in long term workers(≥7 years). Conclusions : The prevalence of CTS in meat and fish processing plant and wood plant were 26.09% and 29.41% respectively. Authors propose that meat and fish processing and wood plants should be managed as a risk job category which were designated by OSHA in 1996
