Background: The aim of our study was to evaluate the “diagnosis changed” rate in patients notified as tuberculosis (TB) on the Korean TB surveillance system (KTBS). Methods: A total of 1,273 patients notified as TB cases on the KTBS in one private tertiary hospital in 2011 were enrolled in the present study. Patients were classified into three groups: “diagnosis maintained”, “diagnosis changed” (initially notified as TB, but ultimately diagnosed as non-TB), and “administrative error” (notified as TB due to administrative errors). Results: Excluding 17 patients in the “administrative error” group, the “diagnosis maintained” and “diagnosis changed” groups included 1,097 (87.3%) and 159 patients (12.7%), respectively. Common causes of “diagnosis changed” were nontuberculous mycobacterial (NTM) disease (51.7%, 61/118), and pneumonia (17.8%) in cases notified as pulmonary TB, and meningitis (19.5%, 8/41) and Crohn`s disease (12.2%) in cases notified as extrapulmonary TB. Being older than 35 years of age (odds ratio [OR], 2.18) and a positive acid-fast bacilli stain (OR, 1.58) were positive predictors and a TB-related radiological finding (OR, 0.42) was a negative predictor for a “diagnosis changed” result via multivariate logistic regression analysis in pulmonary TB cases. Conclusion: Because of a high “diagnosis changed” rate in TB notifications to the KTBS, the TB incidence rate measured by the KTBS may be overestimated. Considering the worldwide trend toward increased NTM disease, the “diagnosis changed” rate may increase over time. Thus, when reporting the annual TB notification rate in Korea, the exclusion of “diagnosis changed” cases is desirable.

한국불교문화의 특성과 제반 문제점들을 최근 사회발전과 변화에 수반되는 현상으로 보지 않고 사바세계의 내재적 문제점들로 인식하고 사바세계를 불국정토로 만들라고 하신 석가세존의 대자 대비한 부촉에 부응하여 변화하고 발전하여 온 불교문화들을 21세기 문화운동의 일환으로 고찰하고자 하였다. 순수문학과 대중문학의 경계를 허물어야 한다고 주장하는 포스트모더니즘에서 일어나고 있는 주요한 변화들을 간단히 개괄함으로써, 사바세계에 대한 불교 문화적 관점이 불교교리를 견강부회한 교리 중심적인 접근이 아니라 보다 합리적이고 다양한 관점에서 접근하였음을 밝히고자 하였다. 21세기 사회 변화발전이 사회전반에 걸쳐, 그리고 종교적으로 어떤 영향을 주었으며, 앞으로 불교문화 운동의 방향성 정립에 어떤 영향을 주었는지 고찰하고자 하였다. 불교문화가 21세기 사회의 특수상황뿐만 아니라 인류사적 측면에서 인간해방과 불국정토 구현이라는 인류 보편적 사상의 실천이었다는 점을 강조하고자 한다. 그런 측면에서 불교의 정신문화적 토양이 21세기 시대정신을 반영하는 문화로 더욱 빛을 발휘할 것이며 발전할 것이라는 점을 논하였다. This paper recognizes the various characteristics and problems arising in the Korean Buddhist culture as an intrinsic properties of the world of suffering(sabha) instead of a phenomena accompanying the recent social development and change. Sakyamuni Buddha gave a sermon to his disciples and followers to seek a path building the Buddhist Elysium Elysium (Sukkavati). The Buddhist cultures, which were changed and developed in response to the requests of Sakyamuni Buddha, are considered as part of the 21st century cultural movement. By a brief overview of major changes in the postmodernism, which argues that the boundary of pure literature and popular literature should be broken, it is tried to elucidate that the Buddhist cultural perspectives of the world of suffering are not farfetched interpretation and religious approach, which distort the society phenomenon to religious doctrine of Buddhism, but more reasonable and diverse approach. This paper investigates how the 21st century social change and development have an influence on the whole society, specifically the religious world, and the establishment of future Buddhist cultural movement direction. Furthermore, it emphasizes the Buddhist culture gives a direction for not only the special situations of the 21st century society, but also by the universal values of human freedom and liberty and manifestation of the Buddhist Elysium. At this point, the fundamental mental culture soil of Buddhism will be shared and developed as the culture that reflects the zeitgeist of the 21st century.

N/A Human cells are almost never spontaneously immortalized in vitro. We tried to immortalize human fetal hepatocytes (h-FH) and evaluate the differentiational status and its change. Methods : Hepatocytes were isolated from a liver fragment of 20 week old fetus and infected with amphotropic recombinant retrovirus containing a temperature- sensitive mutant of SV40 large T antigen and neomycin phosphotransferase gene. G418 resistant colonies were cloned and expanded. The cells which were able to divide more than 30 times were used to analyze various functions. Results : The immortalization rate was 3.3 x 10-8 and two cell lines (C11, D21) were established. C11-60, C11-80, D21-30 and D21-60 (suffix number means the cell division counts) were evaluated. D21-30 was thougt to be imcompletely immortalized because a considerable portion of cells died during culture. The morphology was similar to that of epithelial cells except for D21-30 which looked like fibroblast. The cells grew rapidly at 33oC but stopped growing at 39oC. T antigen and p53 was expressed at 33oC but disappeared at 39oC, which suggest that T antigen binds to p53. Chromosomal changes were so marked that it was impossible to discriminate exact number. Albumin was secreted as about 1/10 as that of h-FH, but alpha-fetoprotein secretion stopped after immortalization. Telomerase was activated in both cell lines except for the incompletely immortalized cells D21-30. Telomere was elongated in competely immortalized cell lines, but it was rather shortened in D21-30 compared to that of h-FH. Macroscopic colonies did not develop in soft agar assay. Conclusions : We successfully immortalized human fetal hepatocytes. Although the cells are not likely to have oncogenicity, the functions are not so good, possibly due to marked chromosomal changes which are thought to occur before telomerase is activated during immortalization step.

N/A Background: Volume overload is one of the most important, correctable factor far blood sure control in hemodialysis patient. But objective parameter for the ideal body weight is not available in clinical field yet. Recently inferior vena caval examination became a possible candidate for an objective parameter for intravascular volume status. Therefore we investigated how inferior vena cava changes during hemodialysis compared with total amount of ultrafiltration and ANP, and also the effect of changes of IVC diameter on LVK Methods: 43 patients on stable maintainance hemodialysis were enrolled. Among them, 21 patients were on antihypertensive medication. Just before and after the hemodialysis, inferior vena cava diameter, plasma atrial natriuretic peptide and left ventricular mass index were measured for each patient. Inferior vena cava was examined at the level just below the hepatic vein during quiet respiration and left ventricular mass index was calculated. Results- Inferior vena cava at expiration(IVCe) was significantly decreased during hemodialysis(before hemodialysis 21.9 4.9 mm, after hemodialysis 18.3 4.4 mm, p = 0.02). Collasibility index was significantly increased during hemodialysis (before hemodialysis 0.24 0.15, after hemodialysis 0.41 0.19, p< 0.001). Atrial natriuretic peptide(ANP) was significantly decreased during hemodialysis (before hemodialysis 252.3±119.0 pg/ml, after hemodialysis 185.6±93.2 pg/ml, p<0.001). Total ultrafiltration amount was significantly correlated with collapsibility change(r=-0.40) and change of ANP(r=-0.41). Left ventricular mass index was correlated with interdialysis weight gain(r=0.39, p<0.05), IVCe after hemodialysis(r=0.48, p<0.05) in univariate analysis but not in multivariate analysis. Conclusion: Collapsibility index of inferior vena cava, IVC diameter and ANP changes reflect the volume change during the hemodiaylsis. Therefore 1VC examination can be an objective parameter for volume change during hemodialysis. Postdialysis 1VCe correlates weakly with left ventricular mass index but it cannot be an independant risk factor for left ventricular hypertrophy in our study.

Background/Aims: Anti-C-reactive protein (CRP) antibody has been introduced as a potential biologic marker in Systemic lupus erythematosus (SLE). The aim of study is to evaluate the level of anti-CRP antibody in patients with SLE. Methods: This study investigated the relationship between levels of anti-CRP antibodies and disease activity markers, such as complement, anti-double-stranded DNA antibody, and SLE disease activity index in 34 patients with SLE. Results: The serum anti-CRP antibody levels of the patients with SLE were significantly higher than those of the healthy controls (11.3 ± 5.6 μg/mL vs. 9.1 ± 2.8 μg/mL). The percentages of the positive anti-CRP antibody were 52.9% in SLE and 27.8% in controls. Disease duration of SLE showed significant correlation with the anti-CRP antibody (r = 0.234, p = 0.026). However no significant relationship was observed between the levels of anti-CRP antibodies and disease activity markers. Conclusions: These data show that the anti-CRP antibody levels of the patients with SLE were significantly higher than those of healthy controls. We observed that the presence of the anti-CRP anti-CRP antibody was not associated with disease activity of SLE.
