        Ji Kang Yun,김웅빈,이상욱,Kwang Woo Lee,Jun Mo Kim,Young Ho Kim 대한요로생식기감염학회 2020 Urogenital Tract Infection Vol.15 No.3

        Purpose: Acute pyelonephritis in older patients can lead to a poorer treatment response and prognosis. The objective of this study was to classify older female patients with acute pyelonephritis according to age and compare their clinical characteristics and antibiotic susceptibility. Materials and Methods: In this retrospective study, 360 patients aged 65 years or older and hospitalized for acute pyelonephritis in a single tertiary medical facility from 2012 to 2016 were selected as research subjects. The patients were divided into three groups according to their age. Their clinical symptoms, blood tests and urinalysis, underlying diseases, causative organisms for urinary tract infections (UTIs), and antibiotic susceptibility were compared. Results: One hundred and seventy-six patients aged 69.9±2.7 years, 142 patients aged 79.4±3.1 years, and 42 patients aged 87.3±3.1 years were assigned into the young-old, old-old, and oldest-old groups, respectively. The duration of hospitalization and fever due to acute pyelonephritis increased with age. On the other hand, the maximum body temperature was similar among the three groups. In blood tests, erythrocyte sedimentation rate and C-reactive protein increased with age. Among the underlying diseases, the incidence of diabetes and chronic renal disease was similar among the three groups, while cerebrovascular diseases, heart failure, and urinary stones were associated with aging. Older patients were more likely to have UTIs over the past year. Older groups showed a more significant decrease in sensitivity to carbapenems, amikacin, and ciprofloxacin. Conclusions: Choosing appropriate antibiotics, considering the patientʼs age, is important when treating acute pyelonephritis.

      • 18–30세 사이에 발생하는 뇌경색의 특징, 다기관 레지스트리 연구

        장윤경,송태진,김용재,허지회,이경열,김영은,장민욱,조수진,강석윤 이화여자대학교 의과학연구소 2017 EMJ (Ewha medical journal) Vol.40 No.3

        Objectives: Although there have been several reports that described characteristics for young age stroke, information regarding very young age (18–30 years old) has been limited. We aimed to analyze demographic factors, stroke subtype, and 3-month outcome in acute ischemic stroke patient who have relatively very young age in multicenter stroke registry. Methods: We evaluated all 122 (7.1%) consecutive acute ischemic stroke (within 7 days after symptom onset) patients aged 18 to 30 from 17,144 patients who registered in multicenter prospective stroke registry, 1997 to 2012. Etiology was classified by Trial of Org 10172 in Acute Stroke Treatment criteria. Stroke severity was defined as National Institutes of Health Stroke Scale (NIHSS) and stroke outcome was defined by modified Rankin scale (mRS) at 3 months after index stroke. Results: The mean age of all included patients was 25.1±3.7 years and 76 patients (62.2%) were male. The median NIHSS at admission was 4. Considering stroke subtype, 37 patients (30.3%) had stroke of other determined etiology (SOD), 37 (30.3%) had undetermined negative evaluation (UN) and 31 (25.4%) had cardioembolism (CE) were frequently noted. After adjusting age, sex and variables which had P<0.1 in univariable analysis (NIHSS and stroke subtype), CE stroke subtype (odds ratio, 4.68; 95% confidence interval, 1.42–15.48; P=0.011) were significantly associated with poor functional outcome (mRS≥3). Conclusion: In very young age ischemic stroke patients, SOD and UN stroke subtype were most common and CE stroke subtype was independently associated with poor discharge outcome.

        정용석(Yong Seong Chung),이영철(Young Chul Lee),서강진(Kang Jin Seo),김명준(Myeong Jun Kim),정지혜(Ji Hea Jeong),노시태(Si Tae Noh) 한국고분자학회 2011 폴리머 Vol.35 No.6

        바이오매스에서 유래된 2,5-dihydroxymethylfuran(DHMF)을 KMnO4 산화반응으로 furan-2,5- dicarboxylic acid(FDCA)를 합성하였다. 합성한 FDCA와 다이올류를 에스테르화 반응과 축중합 반응을 진행시 켜 폴리에스터를 중합하였다. 폴리에스터는 NMR을 통해 조성을 분석하였고 DSC와 TGA를 통해 열적특성을 분 석하였다. 합성된 폴리에스터의 고유점도는 0.78∼1.2 dL/g으로 상용화된 poly(ethylene terephthalate)(PET) 와 비슷하였다. 다이올의 길이가 증가할수록 Young`s modulus와 strength는 낮아지고 elongation-to-break는 높아지는 경향을 확인하였다. 합성한 poly(ethylene furandicarboxylate)(PEF)의 Young`s modulus는 3551 MPa, strength는 103 MPa로 상용화된 PET와 비슷하였다. Furan-2,5-dicarboxylic acid (FDCA) was synthesized by KMnO4 oxidation of 2,5-dihydroxymethylfuran( DHMF) derived from biomass. Polyesters were synthesized by esterification and polycondensation of FDCA with various diols(ethane-1,2-diol, propane-1,3-diol, butane-1,4-diol, hexane- 1,6-diol, decane-1,10-diol). The composition of polyesters was characterized by using 1H NMR. Thermal properties of the polyesters were characterized by DSC and TGA. Intrinsic viscosities(IV) of the polyesters were measured to be 0.78∼1.2 dL/g comparable with IV of commercial poly(ethylene terephthalate)(PET). As the chain lengths of diols increased, Young`s modulus and strength decreased and elongation-to-break generally increased. Young`s modulus and strength of the polyesters were measured to be 3551 MPa and 103 MPa, respectively, comparable with commercial PET.

        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.

        강주찬,지정훈,송승엽,문상욱,강지웅,이영돈,김세재 한국어병학회 2004 한국어병학회지 Vol.17 No.1

        본 연구는 우리나라 주요 양식어류인 넙치, Paralichthys olivaceus를 대상으로 육상수조식양식장 배출물 발효물의 어류 사료 첨가에 따른 혈액학적 변동에 미치는 영향을 검토하였다. 젖산균 및 효모를 사용하여 발효한 양식장 배출물의 이화학적 분석을 실시하였고, 발효물을 0.1, 0.5, 1.0 및 5.0% 농도로 8주간 투여하였다. 투여 4주째 및 8주째에 각 투여 구간별로 혈액학적 항목을 중심으로 그 차이를 확인하였다. 배출물 발효농도별 유의한 차이는 나타나지 않았지만, 분석시기에 따른 적혈구수, 혈색소 농도 및 혈색소 지수가 증가하는 경향을 나타내었으나, 주요 혈청 무기 및 유기성분은 배출 발효물 농도별로 유의한 차이는 나타나지 않았다. 또한 혈청 효소학적 조사에서는 조사시기별로 변동은 나타났지만, 동일 조시시기에서 각 구간별 유의한 차이는 나타나지 않았다. 따라서 이러한 육상 약식장 유래의 배출물 발효산물에 대한 다양한 방면의 연구가 진행되어야겠다. Effects of oral administration with fermented product from sewage in land-based seawater fish farm on haematological disturbance in the olive flounder, Paralichthys olivaceus was investigated. After 4 weeks of conditioning with a basal diet, fish were divided into 4 groups and provided experimental diet (0.1,0.5, 1.0 and 2.0%) supplement of fermented sewage for 80 days. Proximal analysis was performed for the product of sewage which was fermented by lactic acid and yeast. RBC count, hemoglobin concentration and hematocrit value were increased according to the treated periods, however, no statistical difference was observed between control and treatment groups. There were no significant difference in serum organic, inorganic compounds and enzyme activities between control and treatment groups. This study hypothesized that the supplement of fermented product from sewage in land-based seawater fish farm might be an additive sup plement for source of fish diet in view of haematological examination. Recycling of the sewage may be an economic artificial sources of diet for fish aquaculture practices.

        강지훈,진영호,이재백 大韓應急醫學會 1998 대한응급의학회지 Vol.9 No.4

        Basta is one of the Phospho-amino acid group herbicide. It consist of glufosinate ammonium (18.5%), alkylether sulfate as surfactant (30%) and some solvents. Although it's WHO classification is grade Ⅲ, the intoxicated patient appears an serious clinical findings and have a 20% mortality rate. Nowadays, in Korea the ingestion of herbicidal agents for suicidal attempts is frequent. The literature for intoxication of bipyridilium (Gramoxon) as herbicide is varied, but the information for Basta is poor even though the use of it tends to increase. Recently, We experienced six cases of Basta intoxication and found that the patient expressed a gradually progressed depression of mentation, recent memory disturbances, convulsions, hypotension, or bradycardia because of CNS or cardiovascular effects of Basta We report these cases with literature review.

      • McCoy 세포에서 Chlamydia trachomatis의 병원성 인자에 관한 연구

        강정숙,최지영,차영주,김영주,김덕례,여명구,박열 조선대학교 생명과학연구소 1998 생명과학 연구 Vol.6 No.-

        본 연구는 병원성 세균인 Chlamydia trachomatis(C. trachomatis)가 숙주세포에침습시 C. trachomatis의 병원성 인자와 C. trachomatis와 상호작용하는 숙주 세포막의 인자를 규명함으로써 숙주세포에 대한 감염율을 향상시켜 보다 향상된 진단 방법을 개발하기 위하여 수행하였다. C. trachomatis로 감염된 세포에서 기본소체의 막 단백질을 분리한 결과 각 혈청형의 39 kDa과 42 kDa에서 major outer membranes(MOMPs)이 관찰되었으며, 혈청형 E와 G의 MOMPs는 42.5 kDa으로 동일하였지만 혈청형 F, H, I, 그리고 K의 MOMPs는 각각 다르게 관찰되었다. C. trachomatis가 숙주세포로 침습시 관련된 병원성 인자에 대하여 조사하고자 단층세포로 배양된 배양용기에 C. trachomatis를 24, 48 그리고 73시간대별로 접종시켜 관찰한 결과 72시간의 MOMPs의 양이 가장 많이 증가하였으며 이 결과로 MOMPS이 C. trachomatis 병원성에 중요한 작용을 함을 확인할 수 있었다. C. trachomatis가 침습시 숙주세포의 막 단백질 변화양상을 관찰하기 위해 정상세포와 C. trachomatis로 1, 2, 3 그리고 4시간대별로 접종 시간을 달리한 숙주세포의 막 단백질을 분리한 결과 42 kDa의 단백질 양이 Chlamydia에 감염된 세포 내에서 증가됨을 관찰할 수 있었다. 이로 42 kDa의 막 단백질이 침습시 숙주세포 표면에 대한 수용체로서 작용함을 알 수 있었다. The present study was performed to analyze the pathogenic factors involved in the invasion process of Chlamydia trachomatis(C. trachomatis) into McCoy cells. In this study, elementary bodies(EBs) of C. trachomatis serotypes(E, F, G, H, I, K and LGV) could be isolated by the method of Percoll density gradient centrifugation and the pathogens of serotypes were also compared from whole-cell lysates by using sodium dodecyl sulfate-polyacrylamide gel elelectrophoresis. All chlamydial serotypes showed a single predominant protein ranging from 39 to 42 kDa. The major outer membrane proteins(MOMPs) of the E and G serotypes had an identical molecular weight of 42.5 kDa. In contrast, the MOMPs of the F, H, I and K serotypes were showed different molecular weights of MOMPs. By immunoblotting with anti-MOMP antibody it was revealed that the quantify of MOMPs was time-dependently increased when McCoy cells were infected with Chlamydia for 24, 48 and 72 hr. These results indicated that MOMPs are closely related to chlamydial infection into the host cell.

        강위금,이재생,고지연,박창영,정기열 한국환경농학회 2004 한국환경농학회지 Vol.23 No.3

        낙동강 물을 관개하여 벼를 재배하는 강 상류의 안동 풍산에서부터 하류의 부산 구포까지 7개 지역 논토양의 농업환경 특성을 1999년부터 2년간 비교 분석하였다. 토양의 중금속 함량은 자연함량 안팎이었으며 가장 높았던 곳은 부산 강서 지역이었고 다음으로는 고령 성산 지역이었다. 그러나 현미중의 중금속은 자연함량 이하를 보였다. 토양의 화학성은 고령 성산지역과 부산 강서지역에서 높았는데, 1999~2000년도의 영농 후 토양에서 고령은 pH (5.9~6.1), EC(0.8~0.9 dS/m), 유효인산(155~201 mg/kg), 치환성 칼슘(6.7~7.4 cmol^(+)//kg), 치환성 마그네슘(1.92~2.50 cmol^(+)/kg), 치환성 칼리(0.18~0.21 cmol^(+)//kg )가 가장 높았고 부산에서는 유기물(23.0~29.1 g/kg), 총질소(1.6~l.8 mg/kg)가 가장 높았다. 낙동강 물의 관개수질과 토양화학성을 고러한 벼의 진단시비량은 질소의 경우 110 kg/ha를 기준으로 안동 21.4%, 상주 11.85, 구미지역에서 8.8% 정도 증시할 필요가 있었으나, 고령에서는 14.9%, 창녕은 4.6%, 밀양 하남은 4.55, 부산 강서지역은 11.5% 내외로 줄일 수 있을 것으로 분석되었다. 그리고 인산질 비료는 45 kg/ha 기준으로 창녕 도천에서만 18.9% 줄여 주고 다른 지역에서는 기본시비량인 30 kg/ha만 시용하여도 무방할 것으로 판단되었다. 논토양에 분포하는 세균과 사상균, 방선균, 중온성 Bacillus, 형광성 Pseudomonas, Biomass C는 유기물과 총 질소, 인산 등의 양분함유량이 많았던 고령 성산과 그 하류지역에서 높았다. Agroenvironmental characteristics in paddy fields irrigated with the water of Nagdong river were analyzed along the river watershed for two years from 1999. The sites monitored from upper reaches of the river were Andong, Sangju, Gumi, Goryeong, Changnyeong, Milyang and Pusan. In paddy soils, the contents of heavy metals such as Cd, Cr, Cu, Pb, Ni, Zn and As were around natural values showing the highest values in Pusan followed by Goryeong. In brown rice, the contents of heavy metals were lower than natural values. Soil chemical properties appeared higher values in the lower reaches including Goryeong than the upper ones. The highest parameters in Goryeong were pH (5.9~6.1), EC (0.8~0.9 dS/m), Av.P₂O_(5) (155~201 mg/kg), exchangeable Ca (6.7~7.4 cmol^(+)/kg), Mg (1.92~2.50 cmol^(+)/kg), K (0.18~0.21 cmol^(+)/kg) and those in Pusan were organic matter (23.0~29.1 g/kg) and T-N (1.6~1.8 mg/kg). In conclusion, the recommended rates of N fertilizer for rice cropping were 21.4%, 11.8% and 8.8% high for Andong, Sangju and Gumi, respectively and 14.9%, 4.6%, 4.5% and 11.5% low for Goryeong, Changnyeong, Milyang and Pusan, respectively reflecting the chemical properties of soils and the quality of irrigation water on the basis of 110 kgN/ha. In the case of phosphorous, the rates were 18.9% and 33.3% low for Changnyeong and others, respectively on the basis of 45 kgP₂O_(5)/ha. The populations of bacteria, fungi, actinomycetes, Bacillus, fluorescent Pseudomonas and Biomass C were high at the lower reaches including Goryeong, which showed relatively much nutrient contents of organic matter, total N and phosphorous etc..
