Locoregional recurrence is the most common type of recurrence in surgical operation of gastric adenocarcinoma, and peritoneal dissemination is one of the most difficult problems in advanced gastric adenocarcinoma treatment. Because the peritoneal cavity is the most common site of the first recurrence after gastric cancer resection, intraperitoneal chemotherapy seems a logical choice for cancer chemotherapy. In this study, Mitomycin C (MMC)-activated charcoal (CH)-alginate (ALG) beads were prepared by the mixtures of CH particles adsorbed with MMC as an anti-cancer drug and aqueous alginate solution. The alginate is recognized as biodegradable, nontoxic, and biocompatible. The release of MMC from the beads in 0.1 M Tris buffer was stable and continuous until about 1 week. The MMC-CH-ALG beads can be applied in the peritoneal cavity for intraperitoneal chemotherapy since they provide a good adhesiveness on the tissue and controlled release pattern of the drugs.

연구배경: 감염질환은 혈관질환과 함께 당뇨병의 중요한 사망원인의 하나이며, 혈당조절이 불량할수록 감염 빈도가 증가됨은 잘 알려져 있다. 간농양의 발생이 있어서도 당뇨병은 중요한 기저질환 중의 하나이다. 일반적으로 간농양의 가장 흔한 원인균은 Escherichi coli라고 알려져 있으나, 최근 당뇨병을 가진 간농양 환자에서 Klesiella pneumoniae의 검출이 증가되고 있다. 또 최근 연구에 의하면 K.pneumonie가 간농양의 가장 흔한 원인균이며, K. pneumoniae에 의한 간농양은 K.pneumoniae 이외의 균주에 의한 간농양보다 당뇨병과 밀접히 관련되어 있다고 보고된 바 있다. 이에 저자들은 간농양 환자를 대상으로 당뇨병환자의 빈도를 알아보고, 그 원인균 및 특징을 비당뇨병 환자들의 경우와 비교해 보고자 하였다. 방법: 1992년 1월부터 1999년 6월까지 방사선학적 검사 혹은 수술에 의해 간농양이 확인되거나, 경피적 천자나 수술을 통한 배농액 배양, 혹은 혈액 검사에서 원인균이 증명된 182명의 환자를 대상으로 후향적 임상고찰을 실시하였다. 결과: 화농성 농양을 가진 167명의 환자(남:94명, 여:73명)중 당뇨병을 가진 환자는 54명 (남:30명, 여:24명)으로 32.3%를 차지하였다. 환자의 평균나이는 당뇨군에서 62.1 ± 13.4세, 비당뇨군에서는 55.1 ±15.5세로 당뇨군에서 높았으며(p=0.0021), 남녀간의 평균나이 비교 시 두 군 모두 여성의 나이가 의미있게 높았다. 비당뇨군에 비하여 당뇨군의 경우 저알부민혈증의 빈도와 aspartate transaminase가 증가되어있었다. 원인균주는 K. pneumoniae (당뇨군54%, 비당뇨군 39.1%), E. coli(당뇨군 17.5%, 비당뇨군 18.8%), Pseudomonas aeruginosa, Streptococcus viridans, Enterococcus 순이었으며 두 군간의 의미는 차이는 없었으나 K. pneumoniae의 경우 다른 균종에 비해 단독감염의 빈도가 높았다(82.8%). 사망률은 당뇨군에서 16.7%, 비당뇨군에서 7.1%로 당뇨군에서 의미있게 높았으며(p=0.019), 당뇨군에서의 사망환자는 모두 패혈증이 동반되어 있었다. 당뇨환자의 사망군은 생존군에 비해 당뇨병 이환기간이 길고 혼합감염의 빈도가 높았다(p=0.046). 검사실 소견에서는 총 빌리루빈 및 알카리성 포스파타제의 증가가 관찰되어 있었다. 결론: E. coli가 간농양의 주된 원인균이라는 기존 보고와는 달리 당뇨군과 비당뇨군 모두 K. pneumoniae가 간농양의 주된 원인균이었다. 또한 당뇨 유병기간이 길고 당뇨조절이 불량한 환자에서 혼합감염이며 총 빌리루빈 및 알카리성 포스파타제의 증가등과 같은 위험인자가 존재할 경우 사망률이 증가될 수 있으므로 이들 군에서는 적극적인 치료가 필요할 것으로 사료된다. Background: Liver abscesses are commonly associated with underlying disease, particularly diabete mellitus. The number of the liver abscesses caused by Klebslella pneumoniae in diabetic patient has been increased in Korea nowadays. This study was conducted to clarify the clinical presentation and prognostic factors of pyogenic liver abscesses, especially in diabetic patients and to determine the proportion of K. pneunomiae as a pathogen in liver abscess in Korea. Methods: Medical records of 167 patients treated for pyogenic liver abscess from January, 1992 through June, 1999 were reviewed retrospectively in detail. Major Pathogenic organism, clinical manifestations, prognostic factors, the importance of diabetes mellilus as an underlying disease and its effect on clinical features and prognosis were analyzed. Results: Among 167 cases of pyogenic liver abscess, underlying diabetes mellitus was present in 32.3%. The mean age of patients was 62.7 13.4 years in diabetic liver abscess group and 55.1 15.5 years in non-diabetic liver abscess group. Most liver abscesses were cryptogenic in origin or secondary to the billary tree diseases. The clinical presentations among the two groups were not significantly different. When compared to patients without diabetes, patients with diabetes had significantly higher proportions of hypoalbuminemia and elevated aspartate transaminase level. The most common organism of the pyogenic abscess was K. pneumoniae in both groups. Percutaneous drainage of the abscess with appropriate antibiotics was the most commonly used therapeutic modality in liver abscess. The mortality rate of diabetic liver abscess is 16.1 % and 7.1% in nondiabetic liver abscess. Complications, especially septicemla, were found more frequently in patients with diabetes than in patients without diabetes (64.8% vs 28.3%, septicemia : 31.5% vs 9.7%). The factors influencing mortality in the diabetic liver abscess were disease duration, mixed infection, presence of septicemia, elevated bilirubin and alkaline phosphatase. Conclusions: In contrast to prior report that the E. coli was the most common pathogen in liver abscess, we found that K. pneumoniae was the most common organism cultured in liver abscess. Diabetic patients have more complications and higher mortality than patients without diabetes. Early detection and proper treatment are needed to improve the outcome for diabetic patient with liver abscess.

Objectives: In order to evaluated the prevalence and the site of infection of cytomegalovirus in terminally failing heart, cytomegaloviral DNA was detected in the explanted hearts of transplantation recipients. Methods: DNA extractions were performed from explanted failing hearts(N=22) and normal hearts(N=5) and polymerase cain reactions(PCRs) were done for detection of late gene sequence coding pp150 glycoprotein. The products were confirmed by electrophoresis on the 1% agarose gel. n order to improve the detectability of cytomegaloviral genome, nested PCRs were executed with the primers designed for the original 607 bp products. In situ PCRs also were done with the samples which were confirmed as positive for CMV viral genome by nested PCRs. Results: All patients had IgG anti-cytomegalovirus antibody and did not have IgM anti-cytomegalovirus antibody. Cytomegaloviral genomes in myocardium were detected by polymerase chain reaction. The 607bp products by PCRs were found in both explanted failing heart(3 cases/22. 13.5%) and normal hearts( 1 case/5, 20.0%). In nested PCRs, 186bp products were found in both failing hearts(LV 4/22, LA 3/2, RV 4/22, RA 0/17) and normal hearts(LV 2/5, LA 1/4, RV 2/5, RA 2/5). These was no significant change in positivity of cytomegaloviral DNA genome between failing and normal hearts. Total positivity of cytomegaloviral genome in explanted hearts was 44.4% according to the nested PCR results. The positivity of cytomegaloviral DNA by n situ PCR was 33.3%(4/12), and the site of positive reaction was the nuclei of the myocardial cells. Conclusion: Cytomegalovirus was rarely observed in explanted hearts of terminal heart failure and nested PCR could enhance the sensitivity of cytomegaloviral genome detection. The result of the in situ PCR showed the site of the cytomegaloviral infection was nuclei of the myocardial cells. Cytomegalovirus, however, might have no direct causal relationship in the development of terminal heart failure.

흉통과 생활변화, 대처행동양식 및 사회적 지지의 관계 : 관상동맥조영술을 받은 환자들을 중심으로 Focused on Patients Undergone Coronary Arteriography

정진대,국승희,이무석 大韓神經精神醫學會 1996 신경정신의학 Vol.35 No.3

본 연구는 흉통을 주소로 관상동맥조영술을 시행받은 환자 중 조영술상 양성군과 음성군, 대조군의 일반 인구학적 특성, 관상동맥질환의 관련요인, 흉통의 양상, 년간 생활변화량, 대처행동양식, 사회적 지지에 대한 지각의 차이, 기능장애정도 등을 비교하고자 하였다. 처음으로 관상동맥조영술을 시행하는 40명의 환자를 대상으로 의무기록지 검토, 반구조화된 면접, 사회재적응 평가척도, 대인관계지지 평가지, 대처행동 평가지, 기능장애 척도 등을 실시한 후 조영술 결과에 따라 양성군과 음성군으로 분류하였으며 이들과 흉통의 과거력이 없었던 정상대조군을 비교하여 살펴보았다. 요약하면 1) 음성군이 양성군에 비해 유의하게 여성이 더 많았고(p<0.05), 비전형적인 흉통을 호소하는 환자가 유의하게 많았다(p<0.01). 2) 년간생활변화량에서는 음성군, 양성군이 정상대조군에 비해 통계적으로 유의하지는 않지만 생활변화가 많았음을 알 수 있었고, 특히 건강과 관련한 생활변화량에서는 유의하게 높은 점수를 보였다(p<0.05). 3) 대처양식에 있어서는 음성군, 양성군이 소극적인 대처양식(정서완화적 대처)을 유의하게 많이 사용하였다(p<0.01). 4) 사회적 지지도는 음성군이 가장 부정적으로 지각하는 경향이었으나 유의한 차이는 없었다. 5) 기능장애에 있어서는 음성군과 양성군이 현저한 기능장애를 보였으나 두 군간에 유의한 차이는 없었다. 본 연구에서는 흉통환자에서 심리, 사회적인 면이 관여하는 것으로 나타났다. 그러나 다른 많은 연구결과에서 지적하듯 흉통을 호소하는 환자의 많은 수에서 이러한 심리적인 어려움이 있음에도 불구하고 지금까지 정신과적 진단과 치료가 제한되어 있었다. 본 연구는 흉통을 가진 환자들 특히, 관상동맥에 유의한 협착이 없으면서도 지속적인 흉통과 기능장애를 갖는 환자들에게 잘못된 대처양식의 수정과 같은 행동치료, 부정적 지각과 같은 왜곡된 인지에 대한 치료와 같은 정신과적 치료적 중재를 통해 증상의 재발방지와 재활에 도움을 줄 수 있을 것으로 기대된다. 향후 좀더 구체적인 심리적 프로그램에 대한 연구가 계속되어야 할 것으로 생각된다. The purpose of this study was to compare the life change unit, coping behaviors, percived social support, functional disability in patients who had a negative coronary arteriogram and those who had arteriographic evidence of coronary artery stenosis with the matched controls. Patients admitted for coronary arteriography to the cardiovascular department of the Chonnam University Hospital were assessed, on the day before coronary arteriography, on the psychological characteristics using self-rating scales such as Social Readjustment Rating Scale, Interpersonal Support Evaluation List, The Ways of Coping Checklist, and Functional Disability Scale. The results of comparing the psychological characteristics of groups with and without significant coronary artery stenosis and normal controls are as follows : In life change unit, patients with chest pain had significantly elevated health-related life events but no statistically significant differences in total life change. In coping behaviros, patients with chest pain were showed to have more passive coping(especially, tension-reduction coping) than normal controls. In social support, patients with chest pain and negative coronary arteriogram were the most negative cognition but there no statistically significant differences. In functional disability, patients with chest pain showed much higher functional disability score than normal controls. We recognized the relationship of psychological factors to the chest pain patients, psychological terapeutic intervention may provide prevention of symptom relapse and rehabilitation for the negative coronary arteriogram patients with persistent chest pain, and functional disability.

An epidemiologic study on pleuropneumonia in the slaughter pigs(Chonan and Asan area, Chungnam province, Korea) during the period of January 1994 through December 1995 was conducted. Isolation of A. pleuropneumoniae was attempted in 425 pigs with pneumonic lesions. Biochemical properties, antimicrobial susceptibility, serotypes and pathogenicity of A. pleuropneumoniae isolates were investigated. In addition, outer membrane protein(OMP) of the isolates were extracted to determine its properties and immunogenicity in both mice and piglets. Of 3,395 slaughter pigs, pleuropneumonia was observed in 425 pigs(10.6%). A. pleuropneumoniae was isolated from 22 pigs(5.2%) out of 425 pigs with pneumonic lesions. The biochemical properties of all isolates were same as those of reference A. pleuropneumoniae strain. Among 22 isolates, 9, 1 and 12 isolates were serovar 2, 3 and 5, respectively. The results of antimicrobial susceptibility test revealed that the isolates showed high susceptibility to ciprofloxacin and cephalothin, moderate susceptibility to amikacin, gentamicin, kanamycin and streptomycin, and low susceptibility to erythromycin, tylosin and sulfadimethoxin. The isolates were varied in pathogenicity to mice. Median lethal dose of LE9402(serovar 2) and LE9511(serovar 5) were 9.2×10^7CFU and 2.8×10^7CFU, respectively. Specific pneumonic lesions were observed from the infected mice with clinical signs. Bacteria recovery rate was high in the lung, but low in heart blood and tracheas. Serovar 2 was found to be more pathogenic than serovar 5 in guinea pig. Mortality on guinea pigs inoculated with serovar 2(5.4×10^8 - 5.4×10^6CFU) abd serovar 5(2.8×10^8 - 2.8×10^6CFU) was 20-40% and 40-80%, respectively. A severe hemorrhagic lesions and focal pneumonic lesions were observed from dead guinea pigs. Bacteria recovery rate was relatively higher in the lung than that of other organs. In the SDS-PAGE analysis, OMP-enriched fractions of both isolates and reference strains contain common peptide bands equivalent to molecular weight of 17, 27, 42, 52 and 95Kd. In addition to common peptide bands, the bands which are specific to each isolate were also observed. The profiles of Sephadex G25 fractions showed 3 major peaks. The common peptide bands which were observed by SDS-PAGE of the crude OMPs were found i the peaks 1 and 2. The OMPs extracted from serovar 2(LE9402) and serovar 5(LE9511) provided high level of protection in mice(70-80%) and pigs(100%). All animals inoculated with OMPs were seroconverted, showing micro-agglutination titer of 640 to 1280.

Obstructive lung disorders following after allogeneic bone marrow transplantation (BMT) in association with graft- versus-host disease (GVHD) contribute significant morbidity and mortality. We report a case of a 28-year-old man who developed spontaneous pneumomediatinum and subcutaneous emphysema complicating bronchiolitis obliterans after allogeneic BMT. He received an allogeneic BMT for chronic phase of chronic myeloid leukemia. Five months after BMT, he was boostered by allogeneic peripheral blood stem cells from the same donor due to graft failure. One month after the boostering, chronic GVHD developed and were treated with cyclosporine and steroid. The patients developed spontaneous pneumomediatinum and subcutaneous emphysema secondary to severe bronchiolitis obliterans 4 months after boostering donor cells. The air-leak syndromes were recovered by conservative management, including high-flow oxygen.

'선도 추격'에서 '동반 추격'으로의 전환을 위한 서비스 산업의 역할과 전략 : 한일 생산성 비교의 시사

이근,정무섭,김윤지 韓國東北亞經濟學會 2008 동북아경제연구 Vol.20 No.2

The Korean economy has grown very fast over the last decades, but it was an uneven catch-up led by a big business and manufacturing. Now it is time for co-catchup led by both manufacturing and services. This paper analyzes the weight and productivity of the service sector in Korea and suggests for policies for its improvement in productivity. The service sector in Korea is featured by low and declining productivity (both TFP and labor productivity), and a big trade deficits, which is in contrast to the trade surplus in manufacturing. This performance is worse, compared with the situation in Japan. For example, the ratio of labor productivity in service to that in manufacturing is only 14%, compared to 46% in Japan. Causes for the low performance in service include too much regulation and lack of competition due to the closed market. Thus, measures to boost up productivity in service include deregulation and market opening, which would open up the opportunity for learning from foreign companies. Industrial policy should also change from input-oriented one to network-oriented one emphasizing the unity of commodities and services.
