To determine the immunological and biochemical properties of monoclonal antibody against encephalomyocardins viral surface antigen, Balb/c female mice were immuunized with the purified viral surface protein of D-variant of encephalomyocarditis virus and then fused with niyeloma cells(NS-l). Sixteen monocloiial antibody-producing hybridoma cell lines were selected from non-producing hybridoma cell lines. Among them, three hybridoma cell lines produced IgG2b and other thirteen hybridoma cell lines produced IgG1. Two hybridoma cell lines, EDH-S-23 and EDH-S-24, Produced IgG2b and showed highest neutralization titer, 236. The antigenic specificity of these monoclonal antibodies was specific to D-variant of encephalomyocarditis virus. VIoreover, the monoclonal antibody showed specifically the curring effect on diabetes mellitus of mice, which was induced by the D-variant of encephalomyocarditis virus.

Background : Pneumocytitis cainii pneumonia (PCP) can occur in immunocompromised hosts especially such as AIDS or cancer patients. Although recent research had focused on PCP in AIDS patients, few studies have described the clinical presentations of PCP in recipients of stem cell transplantation (SCT). We evaluated the clinical manifestations of PCP in SCT patients admitted at St. Mary's hospital, Seoul, Korea. Methods : The medical records of 17 PCP patients undergoing SCT between Feb. 1998 and Feb. 2000 were reviewed. The diagnosis of PCP was confirmed through the demonstration of Pneumocytitis cainii via either cytology of brochoalveolar lavage (BAL) or histological technique of lung biopsy. CMV disease and CMV infection were confirmed by BAL culture and antigenemia respectively . Results : Seventeen patients were all recipients of allogeneic SCT and 7 of 17 patients were performed non-sibling SCT. Patients presented with symptoms including brief period (4 ∼23 days) of fever (76%), dyspnea (70%), cough (64%), and signs such as rare(58.8%), Sixteen patients (94%) had been receiving immunosuppressive agent such as cyclosporine A (64%) or Fk506 (35%) without PCP prophylaxis. Eleven patients (64%) were treated with corticosteroid with mean dose of 16 mg/day prednisolone and mean duration of 4.6 months after post-SCT period. Twelve patients were co-infected with CMV. Another co-infected miCroorganisms were Pseudomonas aeruginosa, Mycobacterium tuberculosis, herpes simplex virus, parainfluenza virus, Average duration of treatment with trimethoprim-sulfamethoxazole (TMP/SMX) was 21 ±9 days. Four patients died, and three of them were related with PCP. Conclusion : PCP developed frequently in patients who were taking immunosuppressive drug due to graft versus host disease or were not taking TMP/SMX prophylaxis. High risk patients showing fever, cough, or dyspnea should be considered to take early bronchoscopic intervention for detection of PCP. When treat for PCP, it also be considered to the possibility of coinfection such as CMV. (Korean J Infect Dis 33:273∼279, 2001)

Background:Recent development of community health promotion initiative in physical activity and active living requires systemic profiling of community elderly for design of interventions. Especially the social marketing approach to physically active living needs detail information about target population. So the Nam-gu of Busan Metropolitan City did survey as part of National Health Promotion Initiatives. Methods:Reconstructed CDC profiling tool was used to survey. Subjects were selected from District directory. From August 5 to December 13, trained interviewer visited 49 community elderly centers and 2 community elderly colleges. Results : Female seventh decades non-educated ill elderly were majority of subjects. They already had the significant level of knowledge about benefits of physically active living. 63.3% were in maintenance stage and 50.9% exercised lightly to improve health. 62.2% exercised alone. 60.8% of non-exercising were bad health condition. 63.7% had intention to do exercise. The biggest worry of subjects was health problem and 76.8% of subjects got health information from television. Conclusion : Social and behavioral approaches and environment and policy approach looks like matches well to the community elderly of Nam-gu. Especially light walking program associated with more specific health education for independent living looks like strongly recommended.

배광묵,윤지원,고광삼 朝鮮大學校 附設 醫學硏究所 1986 The Medical Journal of Chosun University Vol.11 No.1

The correlation between localization of C-typs virus particles, reverse transcriptase activity and monoclonal antibody production by murine hybridoma cells was studied, In this study, Balb/c female mice were immunized with the purified viral protein of EMC-D virus and then fused with myeloma cells (NS-1). After cloning, monoclonal antidody-producing hybridoma cell lines were separated from non-producing hybridoma cell lines. Reverse transcriptase activity was checked in the supernate of monoclonal antibody-producing hybridoma clones, non-producins- hybridoma clones and myelorna cells as control. Monoclonal antibody-producing hybridoma cells shows statiscally significant higher activity as compare to that of non-producing hybridoma cells. The hybridoma cells which secrete high amount of reverss transcriptase shows significant number of extracellular C-type virus particles, In contrast, non-producing hybridoma cells contains a lot of intracellular C-type virus particles. It is concluded that monoclonal antibody-producing hybridoma cells release signifcant amount of reverse transcriptase and extracellular Otype virus particles, while non-producing hybridoma cells shows less release of reverse transcriptase and contains intracellular C-type virus particles.

노랑초파리 ecdysone 결핍 돌연변이(ecd1ts)에서 기능적 ecdysone수용체 구성분의 발현

김세제,박지권,윤원식,이영기,고영상 제주대학교 생명과학연구소 1998 제주생명과학연구 Vol.1 No.-

In Drosophila, the steroid hormone ecdysone triggers the key regulatory cascades controlling the coordinated changes in the developmental pathway of molting and metamorphosis. Ecdysone action is mediated by heterodimer consisting of the ecdysone receptor(EcR) and ultraspiracle proteins(Usp). Heterodimers of these proteins bind to ecdysone response element and ecdsone to modulate gene transcription. In this study, the transcripts of functional ecdsone receptors and ecdysone response genes(Fbp1 and Uro) in ecdysoneless(ecd-1ts) mutation were analyzed by using a RT-PCR and competitive RT-PCR method. The expression of functional ecdysone receptor components were not correlated with tissue-specific ecdysone response genes(Fbp1 and Uro), Suggesting that several other factors involved in the complexity of various ecdysone responses in Drosphila melanogaster. But we showed that the transcripts of EcR-B1 isoforms were expressed with higher level than those of EcR-A in the late third instar larvae of ecdysoneless(ecd-1ts) mutation.
