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.

Lee,Jun-Ki,Hyun,Sang-Ki,Lee,Sang-Sun,Chai,Jung-Ki 한국자원식물학회 2002 Plant Resources Vol.5 No.1

Twenty-three plants of Japanese apricot (Prunus mume) were collected from several sites around Mountains JIRI in Korea. Japanese apricots having the different morphological features were evenly distributed in the groups made from the cluster analysis, indicating no geographic distributions but artificial vegetations in Korea. Japanese apricots were, as based on the PCR-RAPD techniques, clustered into the three groups; a group (prototype) having the five white petals with the five red sepals, a group (green type) having the five white petals with the five green sepals, and a group (hybrid type) having the more than five red petals with various colored sepals. The prototype apricots showed higher toxicities than other type apricot against bacteria and production of less compounds in TLC plates. The polypetal types of Japanes apricot were related to those of p. armebiaca in the characteristics of seed (the ruggedness), but also to be closed to those of p. armebiaca in PCR-RAPD analysis. The cluster analysis of the twenty three apricots and its related species calculated from the two primers were shown to distinguish relationships of cultivars within species, or of individual plants within cultivars, but also to display the two overlapping bands resulted from PCR-RAPD technique.

납 폭로 근로자에서 δ-aminolevulinic acid dehydratase 유전형질이 zinc protoporphyrin 및 δ-aminolevulinic acid에 미치는 영향

The inhibition of δ-aminolevulinic acid dehydratase (ALAD) in the heme synthetic pathway results in increased protophoryphyrin (ZPP) and δ-aminolevulinic acid (ALA) and is responsible for some of toxicological effects of lead. This enzyme is coded by the ALAD gene containing 2 co-dominant alleles. The polymorphisms of ALAD gene may be related to differential effects of lead on ZPP and ALA, ALAD genotype was measured in 975 Korean male lead workers, of whom 897 were homozygous for ALAD1 (ALAD 1-1 genotype) and 96 were heterozygous for ALAD2 (ALAD 1-2 genotype). Blood lead in subjects with ALAD1 was significantly higher than those with ALAD2 (p = 0.01). No difference between ALAD genotypes was found for age, exposure duration, ZPP, ALA, hemoglobin, hematocrit, body mass index, tobacco and alcohol use. After adjustment for possible confounders, ALA and ZPP became significantly elevated in ALAD1 subjects (p = 0.004 and 0.055, respectively). This result suggests that ALAD1 subjects may be more susceptible to the hematotoxicologic effects of lead than ALAD2 subjects.

Effects of Pilger Rolling and Heat Treatment on Microstructure and Corrosion Resistance of Ag-electroplated 304 Stainless Steel Tubes

Hyun Park,Woo‑Jin Lee,Jae‑Han Son,Han‑Kyun Shin,Sung‑Kyu Hong,Hyo‑Jong Lee 대한금속·재료학회 2022 METALS AND MATERIALS International Vol.28 No.8

We introduce a cost-effective method that combines electroplating with metal cold working processes to manufacture compositetubes with robust corrosion resistance. First, a 3-step electroplating process was developed to form an adhesive anduniform Ag coating on the outer wall of a 304 stainless steel tube. The process consisted of a Ni-strike step for removing thepassivation layer of the initial 304 tube, Cu deposition for smoothing the surface by adding a buffer layer, and Ag deposition. To reinforce the interfacial adhesion between the electroplated layers and the 304 tube and increase the area of the Ag coating,a pilger rolling or pilger rolling + heat-treatment process was performed after the Ag electroplating process. Scanningelectron microscopy of the composite tubes after each process indicated that the as-deposited Ag coating changed fromhaving a rough to smooth surface after only pilger rolling and with additional heat treatment. Electron backscatter diffractionanalysis of the microstructures and textures of the tubes revealed that dynamic recrystallization occurred extensively duringpilger rolling, resulting in the formation of a relatively defect-free grain structure without heat treatment. Furthermore,electrochemical polarization curves determined that the Ag-coated composite tubes are superior to the uncoated 304 tubein terms of corrosion resistance under Cl−atmosphere, owing to the formation of a AgCl passivation layer during testing. Surface analysis of the composite tubes suggests that the properties of the AgCl passivation layer are related to the grainsize of the Ag coating and the density of plastic-deformation-induced defects.

To evaluate the safety and efficacy of Pd withdrawal followed by recombinant alpha- Interferon 2b therapy. Nine patients were given a single daily subcutaneous injection of ^α-Interferon at a dose of 3 x 10 exp(6) units/day for first weeks and thrice weekly for next 15 weeks (maintenance) after pd tappered over 6 weeks. To evaluate the efficacy of therapy, we measured serum aminotransferase activities monthly during and after therapy, and also measured serm HBsAg, HBeAg and DNA probe before and after therapy. To evaluate the safety of therapy, all patients checked peripheral blood WBC, Hemoglobin, Platelet, BUN and Creatinine. The results were as follows : 1. In control group, the normalization of s-AST & ALT level, negative seroconversion of DNA probe & HBeAg were observed in 1/12(8%) & 7/10(17%), 0/10(0%) & 0/12(0%) at 6 months later, and maintained response in 1/11(9%) & 1/11(9%), 2/9(22%) & 2/11(18%) until 1 years later. 2. In treatment group, Serum AST and ALT returned to normal in 8/9 & 8/9 cases (89%) after 1 montns Tx. (mean serum AST : 33±8, ALT : 34±12 IU/ml) and maintained to normal response in 5/9(56%) & 6/9 cases(67%)after 6 months Tx. (mean s-AST : 55±43, ALT : 66±84 IU/ml), 3/9(33%) & 4/9 cases(44%) after 1 years Tx. It was statistically significant reponse except s-AST of after 1 years Tx. 3. In treatment group, s- HBeAg returned to normal in 3/9 cases(33%) after 1 months Tx., and maintained to normal response in 1/7 & 1/4 cases among follow up patients in after 6 & 12 months Tx. Serm DNA probe level were observed significantly negative seroconversion in 8/9 cases(89%) after 1 months Tx. (p<0.003), and maintained to negative response in 2/6 & 1/3 cases after 6 & 12 months Tx. 4. Serum AST, ALT, HBeAg and DNA probe were not significantly correlated with therapeutic response in relation to histologic diagnosis. 5. Fever and myalgia were noted in 9(100%) & 6(67%) cases. Headache, mild hair loss, anorexia, nausea, facial flushing & diarrhea were noted in few cases. Peripheral WBC(3cases) & platelet counts(3cases) were decreased transiently. This study shows that Pd withdrawal followed by recombinant alpha Interferon 2b therapy may be safe and effective in decrease the level of s-DNA probe, transaminase activity, loss of HBeAg and less adverse effect of clinical and hematologic examinations in patients with CAH type B. But it was necessary for study with large number of patients, more prolonged follow up duration and more strict control study.

Objective In order to study the effects of bee venom(BV) on the pain, edema, and acute inflammatory reactant of rheumatoid arthritis(RA) patients. Methods Patients with RA who met the ACR(American College of Rheumatology) 1987 revised criteria for the diagnosis of RA were treated with the BV therapy twice a week for 3 months. Tender Joint counts, swollen joint counts, Visual analog scale(VAS), morning stiffness, ESR. C-reactive protein(CRP) were analyzed before and after BV therapy. Results The results as follows. 1. Tender joint counts in patients after BV therapy were significantly lower than those before BV therapy(9.0±7.9 vs 15± 11.4, p=0.002). 2. Swollen joint counts of the patients after BV therapy were significantly lower than those before BV therapy(50±61 vs 15±23, p=0.001). 3. VAS in patients after BV therapy was significantly lower than those before BV therapy(608± 17.6 vs 380± 159, p=0.000). 4. Duration of morning stiffness in patients after BV therapy was significantly reduced compared with that before BV therapy(119.1± 112.6 min vs 59.0±89.7 min, p=0.009). 5. ESR and CRP were not significantly changed before and after BV therapy, suggesting BV itself could make inflammatory reaction as well as therapeutic effect. Conclusions BV therapy improved tender joint counts, swollen joint counts and duration of morning stiffness in this study, and further study is needed on long-term effect of BV therapy.

In order to obtain an useful information for health management and biological monitoring of lead exposed workers, Authors tried to investigate air lead level and the lead exposed level of workers in lead industry according to occupational category. The subjects in our study were 2074 workers in 7 lead-using industries, and study subjects were divided into 4 occupational categories such as storage battery industry (type 1), primary smelting industry (type 2), secondary smelting industry (type 3) and litharge making industry (type 4). Blood zincprotoporphyrin concentration (ZPP), blood lead concentration (PbB) and urinary δ -aminolevulinic acid (ALAU), hemoglobin (Hb), hematocrit (Hct) were selected as the indices of lead exposure. Personal variables such as age, work duration were also collected. The results were as follows. 1. The geometric mean air lead in 9 lead-using industry was 0.1133±4.3120 ㎎/㎥, and that in type 1, 2, 3 and 4 was 0.1038±3.4952 ㎎/㎥, 0.0429±3.4329 ㎎/㎥, 0.1877±2.5123 ㎎/㎥ and 0.9961±5.2910 ㎎/㎥, respectively. 2. The mean ZPP in 9 lead-using industry was 53.1±28.0 ㎍/㎗, and that in type 1, 2, 3 and 4 was 52.0±24.8 ㎍/㎗, 48.0±16.4 ㎍/㎗, 109.8±85.6 ㎍/㎗ and 74.3±37.8 ㎍/㎗, respectively. There was significant difference in ZPP according to occupational category (P<0.01). The percents of lead workers whose ZPP were above 100 ㎍/㎗ in type 1, 2, 3 and 4 were 4.0%, 1.7%, 34.3% and 21.6%, respectively. 3. The mean PbB in lead-using industry was 26.0±11.2 ㎍/㎗, and that in type 1, 2, 3 and 4 was 25.3±11.1 ㎍/㎗, 26.7±8.8 ㎍/㎗, 50.3±15.2 ㎍/㎗ and 36.4±11.0 ㎍/㎗, respectively. There was significant difference in PbB according to occupational category (P<0.01). The percents of lead workers whose PbB were above 40 ㎍/㎗ in type 1, 2, 3 and 4 were 10.4%, 7.7% 71.9% and 43.2%, respectively. 4. While the correlation of Hb corrected PbB with ZPP was higher than non corrected PbB, the correlation of log-transformed ZPP with PbB was higher than non corrected ZPP. 5. Simple linear regressions of PbB and corrected PbB as independent variable with ZPP, log-transformed ZPP and ALAU as dependent variable were statistically significant (P0.01). Coefficient of determination of corrected PbB with other variables was higher than non corrected PbB. As the result of this study, it was suggested that reconsideration of environmental and biological monitoring program was highly recommended for secondary smelting and litharge making industry.

신장이식은 환자의 삶의 질을 높이고 거의 정상적인 사회생활을 가능하게 함으로써 말기신부전 환자의 3가지 신대체 요법(혈액투석, 복막투석, 신장이식) 중에 가장 효과적이고 각광받는 치료법이라 할 수 있다. 최근 들어 의료기술과 의학의 발달로 신장이식의 성공률은 과거에 비해 비약적으로 높아지고 있으며 국내에서도 점차 신장이식수술을 받는 환자가 증가하고 있으나 서울이나 다른 대도시에 비해 의료환경이 열악한 중소도시나 지방의 병원에서는 아직도 시행하지 못하고 있는 형편이다. 이에 저자들은 경북 최초로 자체 의료진에 의해 고혈압과 말기 신부전으로 동국대 포항병원에서 혈액투석을 받고 있던 32세의 남자환자에게 부인으로부터 신장을 제공받아 신장이식을 성공적으로 시행하였기에 문헌고찰과 함께 보고하고자 한다. Kidney transplantation is the preferred treatment modality for many patients with end-stage renal disease (ESRD), because it offers improved quality of life over both hemodialysis and peritoneal dialysis. Patients who do well after transplantation generally report improvement in vitality and freedom to return to the style of life that they experienced before their progression to ESRD. Recently, the success rate of kidney transplantation is greatly being increased as the surgical technique and immunosuppressive drugs are developed. Kidney transplantation is also popular in Korea which has good result. But, until now the general hospitals which are located at small city can't try the kidney transplantation because they don't have proper facilities and experts. We firstly experienced a case of kidney transplantation in a 32 years old man with hypertension and chronic renal failure at KyoungBuk province. So we report this case with references.
