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.

The main purpose of this study was to select a B. schmidtii population which has high cadmium tolerance and remediation and to determine the difference of cadmium uptake patterns among populations. One-year-old B. schmidtii seedlings were treated with 0, 0.4, 0.8mM CdSO₄ *3/8H₂O for two months. Cadmium concentrations in different positions of stem and cadmium concentrations and contents of leaves, stems and roots were analyzed. Also soil cadmium concentrations were analyzed. B. schmidtii was highest in root and lowest in shoot tip, showing a gradual decrease from root to shoot tip. The shoot to root Cd concentration ratios were over 1.26. It is concluded that B. schmidtii has good potential for phytoextraction as a shoot accumulator, which can be used for remediation of cadmium-contaminated areas. But tolerance differs between populations. Therefore B. schmidtii should be used as a means of phytoremediation after selection for Cd tolerance is performed.

Acute torsion of the ovary and ovarian mass is a recognized surgical emergency, but rarely has the diagnosis been made preoperatively on the basis of imaging studies. The sonographic findings in 14 cases of surgically proven torsion of the ovary and ovarian mass are described. Mostly cystic ovarian mass, engorged vessel, dilated uterine tube, beak-like echo(torsion site), smooth mass wall thickening an free-fluid collection in cul-de-sac are described. More significant in terms of specificity were the demonstration in 6 cases(42.9%) of the smooth mass wall thickening and in 8 cases(57.1%) of a free fluid in the cul-de-sac. We report the sonographic findings of ovary and ovarian mass torsion that may suggest the preoperative diagnosis of this condition.

To investigate the renal effects of enrofloxacin administration on rats induced with dehydration or hyperoxaluria, male rats were treated with enrofloxacin of 50 mg to 500 mg/kg b.w.. The microscopical observations of kidney and urine sediment were carried out in the experimental groups. The result obtained were as follows; The male rats deprived of water for 72 hours and administered with enrofloxacin. As enrofloxacin administration dose was increased, clinical signs such as loss of appetite, depression, weakness, and loss of urine output became more severe. In the histopathological findings, there were hyperemia and hemorrhage in renal cortex, vacuolation and necrosis of renal tubular epithelia, proteinous casts within renal tubules. The male rats were orally administered with sodium oxalate and injected with enrofloxacin for 7days. As enrofloxacin administration dose was increased, clinical signs such as the loss of appetite and water consumption, and weakness became more severe. In the histopathological findings, there are hemorrhage of glomeruli and cortical hyperemia, vacuolation and necrosis of tubular epithelia, proteinous casts in renal tubules. In the microscopical findings of urine sediment, there are calcium oxalate crystal (diamond-like type) and magnesium ammonium phosphate crystals (rhomboid). The male rats were intraperitoneally injected with sodium oxalate and administered with enrofloxacin for 7days. As enrofloxacin administration dose was increased, clinical signs such as the loss of appetite and water consumption, weakness were more severe. In the histopathological findings, there were hyperemia and hemorrhage in both glomeruli and renal cortex. Severe necrosis of renal tubular epithelia, bluish materials within renal tubules were also found. In the microscopical findings of urine sediment, there were many calcium oxalate crystals. The present results suggest that enrofloxacin has some injurious effects in rats having dehydration or hyperoxaluria, and clinically, we should consider these renal injury effects when we use enrofloxacin in patients accompanied renal disease, dehydration and hyperoxaluria conditions.

본 연구는 Cd 처리에 대한 박달나무 유묘의 가계 간 엽록소 함량과 효소홀성에 의한 피해 및 항산화 내성 반응의 특성을 구명하고자 실시하였다. Cd 처리는 3가계의 박달나무 1년생 묘목에 0, 04, 08mM CdSO₄·8/3H₂O 용액을 이용하여 3수준으로 2개월간 실시하였다. 박달나무의 가계간 및 처리 간 피해내성반응은 엽록소 함량과 MDA(malondialdehyde) 함량, 단백질 함량, SOD(supetoxide dismutase) 활성을 이용하여 결정하였다. Cd 처리는 박달나무의 잎 내 광색소의 함량비를 변화시켰으며, 생리적 피해 지표인 MDA 함량은 모든 가계의 Cd 처리구에서 대소구보다 높게 나타났다. 또한 모든 Cd 처리구의 단백질 함량은 대조구보다 높았으며, MDA 함량과 단백질 한량은 Cd 처리 농도가 증가함에 따라 증가하였다. 한편 Cd 처리된 박달나무의 잎 내 SOD 활성은 대조구보다 증가하였으나, 0.8mM Cd 처리된 9번 가계 경우는 대조구보다 낮아졌다. 즉 박달나무는 Cd 처리에 의해 광색소 함량의 변화 및 MDA 함량 증가와 같은 생리적인 피해를 나타냄과 동시에 단백질 함량과 SOD 활성 증가를 통해 내성 반응을 나타냈다. 그러나 이리한 생리적인 피해 및 내성 반응은 가계 간에 뚜렷하게 달랐다. We investigated differences among half-sib families of Betula schmidtii seedlings in the effect of three Cd levels on physiological injury and antioxidative reaction. One-year-old seedlings of B. schmidtii were treated with 0, 0.4 and 0.8mM CCdSO₄·8/3H₂O for two months. Physiological injury and antioxidative reaction to three levels of Cd treatment determined with using photosynthetic pigments, MDA, protein contents, and SOD activity in the leaves of three half-sib families of B. schmidtii. The ratios of contents among photosynthetic pigments in the leaves of B. schmidtii were changed by Cd treatment. In additon, MDA content in the leaves of plants under Cd stress increased relative to control plants, and total protein content was also higher in the leaves of 0.4mM and 0.8mM Cd levels than control plants. The contents of MDA and total protein also increased with increasing the concentrations of Cd treatment. SOD activity in the leaves of three half-sib families increased by Cd treatment, but SOD activity of No. 9 family decreased relative to control plants at 0.8mM Cd level. In our trial, B. schmidtii treated with Cd represented physiological injuries such as the changes of photosynthetic pigments ratio and the increase of MDA content. At the same time, B. schmidtii showed tolerance responses against Cd toxicity through increasing the total protein content and SOD activity. But the physiological injury and tolerance responses were significantly different among three half-sib families exposed to 0.4mM and 0.8mM Cd.

Tsutsugamushi disease is an acute febrile illness caused by Orientie. tsutsugsmushi. It is characterized by fever, myalgia, lymphadenopathy, and rash. And it can be easily diagnosed by characteristic eschar and serologic testing. Nearly all of the patients with tsutsugamushi disease improve with antibiotics such as doxycycline. However, the fatality rate of untreated cases is seven to ten percent. Splenic infarction is not common disease which is caused by occlusion of the main splenic artery or any of its branches. It is mainly caused by emboli that arise from cardiovascular disease, but sometimes by regional thrombosis associated with leukemia, myeloproliferative disorder, sickle cell anemia, pancreatitis, splenic torsion and septicemia. We experienced one case of tsutsugamushi disease with splenic infarction, which was improved after doxycycline treatment finished.
