목적 : 제일제당에서는 녹농균의 세포외막 단밸질을 유효성분으로 하는 백신인 CFC-101을 개발하였으며, 동물시험에서 이 백신의 안전성과 유효성을 입증하였다. 본 연구에서는 이 녹농균 백신의 인체에 대한 안전성과 면역원성을 평가하는 동시에 인체 접종시의 최적 투여 용량을 결정하기 위하여 제 I/Ⅱa상 임상시험을 수행하였다. 방법 : 건강한 성인 남자를 피험자로 선별하여 각 용량군에 백신투여자 6명, 위약투여자 2명을 배정하였다. 백신 투여군은 0.25mg, 0.5mg 또는 1.0mg 용량의 녹농균 백신을 7일 간격으로 3회에 걸쳐 근육주사 하였으며, 위약 투여군에게는 세포외막 단백질을 제외한 동일한 성분을 투여하였다. 백신접종 후 국소적 또는 전신적인 반응의 발생여부를 관찰하고, 혈액시료를 체취하여 백신의 역가와 유효성을 검정하였다. 결과 : 녹농균 백신 CFC-101은 모든 접종자에서 양호한 내약성을 보였다. 또한 0.5mg 과 1.0mg 백신 투여군에서는 100%의 항체양전율을 나타내었다. 생성된 항체는 녹농균 세포외막단백질에 특이성을 보였고, 녹농균 감염에 대해 방어효능이 있었다. 결론 : 이와같은 결과로부터 이 녹농균 백신은 인체에 안전하게 투여할 수 있으며, 높은 항체 생성능으로 감염방어 효능을 보이고 0.5mg과 1.0mg이 최적용량인 것으로 판단되었다. Background : We developed a Pseudomonas aeruginosa outer membrane protein(OMP) vaccine CFC-101, and the prophylactic efficacy of which has been demonstrated in animal models. In order to evaluate the safety and immunogenicity of the P. aeruginosa vaccine, we carried out a phase I/Ⅱa clinical trial in healthy male volunteers. Methods : Groups of eight volunteers, including two placebo subjects, were vaccinated intramuscularly with three doses of 0.25, 0.5 or 1.0 mg of the vaccine at one week intervals. Sings of systemic and local reactions observed after vaccination were recorded for each vaccinee for 5 days. Physical examinations were performed on days 0, 1, 7, 8, 14, 15, 21, and 42, and clinical laboratory tests were done on days 0, 3, and 21. Blood samples for assay of serum antibody levels were obtained up to 42 days after the first vaccination. Results : The vaccine was generally well tolerated by all vaccinees, showing no significant side effects. In the three dosage groups, all vaccinees, except one receiving the 0.25 mg dose, showed significant elevation in serum IgG antibody titers against the vaccine proteins, indicating 100% seroconversion in 0.5 and 1.0 mg groups. The human antibodies induced by the vaccine were specific for P. aeruginosa OMPs, as confirmed by western blot analysis and immunoprecipitation assays. The capacity of the human antisera to enhance opsonophagocytic killing activity by polymorphonuclear leukocytes and to confer protection against P. aeruginosa infections indicates that the antibodies elicited by the vaccine have protective efficacy. Conclusion : We conclude that the P. aeruginosa OMP vaccine is safe and effective for human use and its optimal dose to be 0.5 or 1.0 mg.

Object : The aim of this study was to assess the clinical indicators related to Pattern-Identification(PI) in acute cerebral infarction patients. Methods : We studied hospitalized patients within 30days after ictus, who admitted at Korean Medicine Center of Kyung-Hee University from January 2010 to October 2012.(n=290) Two Traditional Korean Medicine(TKM) physicians evaluated the patients independently and diagnosed PI. Inter-rater reliability was measured using simple percentage agreement and the Cohen's kappa(κ) coefficient. To assess the clinical indicators closely related to each PI, we analysed average score of each indicator in each group. Results : Simple percentage agreement of PI between raters was 64.83% and Cohen's kappa(κ) coefficient was 0.526(95% CI: 0.451-0.600). Inter-rater reliability level was fair to good. We analysed the clinical indicators in each group. Significant indicators for Fire-Heat Pattern(FHP) were reddened complexion and strong pulse power, and meaningful indicators for FHP were halitosis and thick tongue fur. Significant indicator for Dampness-Phlegm Pattern(DPP) was overweight and there was no meaningful indicator. Significant indicator for Yin-Deficiency Pattern(YDP) was dry tongue fur and meaningful indicator for YDP was thirst. There was no significant indicator for Qi-Deficiency Pattern(QDP) and pale complexion and faint low voice were meaningful indicators for QDP. Conclusions : This study reveals the significant and meaningful clinical indicators related to each Pattern-Identification in acute cerebral infarction patients. It will contribute to standardization of Korean Medical Diagnosis and Treatment in acute cerebral infarction patients.

우희연,이남용,맹성호,한승훈,인경수,김상욱,성승용,김익상,최명식 대한화학요법학회 2000 대한화학요법학회지 Vol.18 No.3

목적 : 병원 감염과 지역 감염의 원인균으로서의 중요성이 증가되고 있는 MRSA와 MRCNS의 메티실린 내성 관련 유전자에 대해 분자역학적인 조사를 시행하고 mec 조절유전자의 다양성을 분석하여 분자유전학적 연구와 감염 관리에 기본적 자료를 제공하고자 연구를 시행하였다. 방법 : 본 연구에서는 국내 동일 대학병원에서 분리된 mecA 양성 MRSA 78균주와 MRCNS 36균주를 대상으로 항균제 감수성 검사와 중합효소연쇄반응을 시행하여 표현형과 유전형의 분포를 알아보고 내성 정도와 유전형의 상관성을 분석하였다. 결론 : 최소억제농도를 측정하여 oxacillin 감수성 양상을 알아본 결과 총 90개의 MRSA 임상검체 중 3균주에서 감수성을 보였고, MRCNS 36균주는 모두 내성을 보였으며, 고도 내성을 보이는 균주일수록 다제내성을 보이고 있었다. 중합효소연쇄반응으로 mecA 유전자 유무를 분석하여 mecA 양성을 보인 MRSA 78균주와 MSCNS 36균주 만을 대상으로 mec 조절유전자에 대한 중합효소연쇄반응을 시행하여 유전형의 분포를 조사하였다. 그 결과 MRSA와 MRCNS 모두에서 mecA-Pr-mecA-mecR1-mecI형, mecA-Pr-mecA-mecR1형과 mecA-Pr-mecA-mecR-1의 5′말단형의 3가지 유전형이 공통적으로 관찰되었는데, 이외에 MRSA에서는 mecA-mecR1형, mecA-mecR1의 5′말단형이, MRCNS에서는 mecA-Pr-mecA형과 mecA형이 추가로 분리되었다. 유전형의 분포를 연도별로 분석한 결과 연도별로 우세한 유전형이 서로 다른 것을 알 수 있었다. 유전형과 내성 정도의 상관성을 분석한 결과, mecA-Pr-mecA-mecR1을 보유한 MRSA의 경우 mecA 억제유전자로 생각되는 mecI 유전자 유무에 관계없이 모두 고도 내성을 나타내어 mecI의 유무는 내성 정도와는 일정한 관련이 없었으나, MRSA와 MRCNS 모두에서 mecI와 동시에 mecR1의 3′말단이 결혼된 유전형이 저도 및 중등도 내성을 보이는 균주에서 유의하게 많이 관찰되어 mecI가 결손된 균주에서는 mecR1의 3′말단부위의 유무가 내성 정도의 결정에 중요한 역할을 할 것으로 생각하였다. 결론 : 국내에서 분리되는 메티실린 내성 포도구균의 유전형의 분포가 국외 분리주와 차이를 보이는 것으로 관찰되었다. 또한 기존의 보고와는 달리 메티실린 내성 정도와 유전형 사이에 유의한 연관성이 있는 것으로 관찰되어 mec조절유전자가 내성 발현 뿐만 아니라 내성 정도의 결정에 중요한 역할을 하는 것으로 관찰되었다. MRSA가 중요한 감염균임에도 불구하고 아직까지 MRSA의 내성기전에 대해 확실하게 규명되지 않아 치료가 더욱 어려워지고 있는 실정이므로 이에 대한 더욱 종합적인 연구와 동시에 발생과 확산을 막기 위한 노력이 필요할 것으로 생각된다. Background : High prevalence of methicillin resistance has been noticed in staphylococci which also have been recognized as important nosocomial and multi-drug resistant pathogens. In this study, we investigated the distribution of mec regulator genes and the presence of the mutation in mecIgene to reveal the resistance mechanism at molecular level. Methods : The isolates included 90 clinical isolates of MRSA, 36 MRCNS of which methicillin resistance were determined by disk diffusion test and isolated in a single hospital during 1996-1999. We performed microdilution MIC test for oxacillin resistance and Kirby-Bauer test for other antibiotics. Genotypes of mecA positive (determined by PCR) isolates (78 MRSA, 36 MRCNS) were investigated by PCR amplification of mec regulator genes such as 3' end and 5' end of mecR1. mecI, and Pr-mecA. Results : In MIC assay, all MRSA strains except 3 strains and all MRCNS strains showed oxacillin resistance. The level of resistance correlated to the multi-drug resistance. Seven genotypes were observed in mecA positive MRSA and MRCNS. Differences of predominant genotypes among years isolated and among species were observed. Deletions of the 3' end of mecR1 and the mecI were more frequently observed in the low- and borderline-level resistant MRSA and MRCNS (P(0.05). So the important role of 3' end of mecRI in determining resistance level was suggested. Conclusion : This study demonstrated that genomic distribution of methicillin-resistant staphylococci isolated in Korea was different from that of strains isolated in other countries. And important role of mec regulator genes for expression of methicillin resistance was suggested.

Objectives:This study was to identify weight & metabolic changes in first-episode psychotic patients with antipsychotics use and investigate the differences of weight & metabolic changes between first-episode psychotic patients and controls with antipsychotics use. Method:In this retrospective study, twenty eight first-episode psychotic patients and twenty eight controls with schizophrenia, schizoaffective or bipolar disorder defined by DSM-IV criteria were included. Information about demographic and clinical characteristics of the subjects was gathered from the medical records. Also body weight, sBP, dBP, fasting glucose, lipid profile and WBC count were evaluated before and after antipsychotics use. Rogistic regression was conducted to assess factors associated with weight gain. Results:First-episode psychotic patients showed more weight and BMI changes than controls after antipsychotics use, and these changes continue over 12 months. On the other hand, there were no significant factors associated with weight gain. Conclusion:The results of present study suggest that antispychotics is one of the major causes inducing weight gain of psychotic patients and antipsychotics-induced weight gain is more vulnerable to drug-naive first-episode psychotic patients.

Extension of Lance Life by Change of Height of Lances in the Smelting Furnace of Mitsubishi Process

Sung‑Mi Lim,Soo‑Sang Park,Kyung‑Woo Yi 대한금속·재료학회 2021 METALS AND MATERIALS International Vol.27 No.10

A Mitsubishi process, which pertains to continuous Cu production, involves a smelting furnace, cleaning furnace, and convertingfurnace connected in series. One of the main issues pertaining to the smelting furnace is the frequent interruption ofoperations required to allow the inspection and replacement of lances, because lances are frequently fractured. The presentstudy was aimed at modifying the operating conditions of the smelting furnace to suppress lance fractures. A numericalmodel was developed to simulate the transport phenomena in the furnace, including multi-phase behaviors. The simulationresults showed that the lances were exposed to a severely erosive atmosphere with high temperatures. Further calculationindicated that raising the positions of the lances could lower the temperature of the lances, and reducing the occurrence ofsplashed melt, which contains erosive sulfides. The smelting furnace was operated under the conditions of the raised lanceheight and attentively monitored for several months. It was confirmed that by implementing such a change of the lanceheights, the occurrence of lance failures has been considerably reduced without notably affecting the reaction ability of thesmelting furnace.
