      • 間歇的 運動에 의한 脫水 및 水分攝取의 生理的 效果

        朴哲浩,朴吉俊,李相于,金永明,朴贊熙,玄松子,呂南會,朴相甲,金榮俊 東亞大學校附設스포츠科學硏究所 1989 스포츠科學硏究論文集 Vol.7 No.-

        This study aims at revealing the physiological responses of dehydration (DH) and rehydration (RH) in intermittent exercises at the work intensity of 70% HR max. First, with general student public, three times of exercise (each for 20 minutes) at the given work intensity were taken, with a break for 25 minutes respectively. Their heart rate, rectal temperature and plasma electrolyte concentration both DH and RH were measured. Second, in two groups of athletes and non-athletes, 9 rounds of exercise (for 100 minutes) and 8 breaks (for 60 minutes) were taken, with RH forced 10 times to compensate for the subjects' water loss. Their change in sweat loss and plasma electrolyte concentration as well as the IVDP(Intensive Voluntary dehydration Phenomenon) were experimented. The summary of this research follows. 1) Mean heart rate and rectal temperature in intermittent exercises were higher at DH than at RH, growing up at the increasing level of DH. 2) RH saw no change in the plasma concentration of Na+, K+ and Cl-, while DH observed a significant increase. 3) HCO₃made a significant decrease at DH before growing up. 4) Mg++ had no change, while Ca++ increased significantly at RH and DH. 5) Lactate showed an increase with significance at RH and DH, especially greater at DH. 6) Osmotic pressure increased meaningfully at DH. 7) Anion gap increased significantly at DH and RH. 8) On the other hand, when the forced RH was held, the group of athletes had greater sweat loss per body surface area than that of non-athletes. 9) The athletes' plasma concentration of Na+ and Cl- revealed a clear decrease. 10) There was seen no significant change in the plasma concentration of K+, Mg++ and Ca++ in both groups. 11) The IVDP occurred at the RH of 2.3ℓfor athletes and more than 2.5ℓfor no-athletes.

        흰쥐 Kupffer 세포에 대한 Propofol의 작용

        박세훈,지대림,성언기,김희선,송인환,박희영,김준수,이덕희,박대팔 대한마취과학회 2002 Korean Journal of Anesthesiology Vol.43 No.4

        Background: Propofol has an antioxidant capacity and can be used for ischemia-reperfusion injury of the liver. However, the effects of propofol on the Kupffer cells have not been establisked. Methods: Kupffer cells were isolated and cultured from male Sprague-Dawley rats. The effects of propofol on the Kupffer cells were evaluated by a phagocytosis assay, TNF-α gene expression, and superoxide anion release after administering propofol in different concentrations on the cultured Kuprrer cells. Results: The latex bead phagocytosis by the Kupffer cells was suppressed when the Kupffer cells were exposed to propofol irrespective of concentrations. Higher propofol concentrations decreased the loss of Kupffer cells after latex bead phagocytosis. Propofol induced TNF-α mRNA expression in the Kupffer cells, but the mRNA expression level after 50㎍/ml of propofol decreased. The pattern of TNF-α mRNA expression induced by propofol was different to that induced by LPS: TNF-α mRNA was expressed continuously in the propofol-treated cells until 16 hours after exposure to propofol, whereas the level of TNF-α mRNA expression induced by LPS was evident after 2 hours and was not found thereafter. TNF-α production after propofol treatment was not higher than that of the control. Formazan presipitation did not show any qualitative differences between cells untreated or treated with propofol concentrations of 0.5, 5.0, and 50 ㎍/ml. Conclusions: These results showed that propofol might inhibit Kupffer cells. This suggests that propofol and be used for patients with ischemia-reperfusion injury of the liver.

        박정원,송준영,김철현,정희진,김우주,김민자,박승철 대한화학요법학회 2000 대한화학요법학회지 Vol.18 No.4

        목적 : 국내 및 전세계적으로 methicillin-resistant Staphylococcus aureus (MRSA), penicillin-resistant Streptococcus pneumoniae(PRSP), β-lactamase 생성 H. influenzae 등의 항균제 내성 감염증이 증가되고, 이에 대한 효과적인 항생제 요법에 대한 필요성이 증가되고 있다. Streptogramin 계열의 경구 항생제인 pristinamycin의 임상검체에서 분리된 균주에 대한 시험관내 항균력을 검사함으로서 이러한 감염증에 대한 임상적 사용의 유용성여부를 알아보고자 하였다. 방법 : 1999년 8월1일부터 2000년 1월 1일까지 호흡기 감염, 피부 및 연조직 감염환자로부터 분리된 MRSA 60주, PRSP 50주, H. influenzae 40주를 대상으로 pristinamycin을 비롯한 8-9종 항생제의 시험관내 항균제 감수성을 측정하였다. 결과 : Pristinamycin은 MRSA에 대한 MIC 범위가 0.125-1㎎/L로서 100%의 감수성을, PRSP에 대한 MIC 범위가 0.125-1㎎/L로서 100%의 감수성을, β-lactamase를 생성하는 H. influenzae에 대해서도 MIC 범위가 0.25-2㎎/L, 96% 감수성으로서 다른 항생제들에 비하여 우수한 시험관내 항균력을 나타내었다. 결론 : 국내에서 문제가 되고 있는 MRSA, PRSP, β-lactamase 생성 H. influenzae에 대하여 pristinamycin은 우수한 시험관내 항균력을 나타내어, 이들 항생제 내성균들에 의한 감염증의 치료에 효과적으로 사용될 수 있을 것으로 생각된다. Background: Pristinamycin(Pyostacine®) is a natural antibacterial combination of compounds Produced by Streptomyces pristinaespiralis. It has been marketed in European countries over 30 years as an oral anti-stphyhcoocal agent. Because of the increasing prevalence microorganisms that are resistant to multiple antimicrobial agents in Korea. there are demand of noble antibiotics like pristinamycin against these resistant organissms. Methods The one-hundred and fifity bacterial strains which were collected from Korea University Guro hospital included sixty methicillin-resistant S. aurous (MRSA) , fifty penicillin-resistant S. pneumoniae (PRSP) and forty H. infuenzae clinical isolates. Using an microbroth dilution or agar dilution technique, we compared the antimicrobial activities of pristinamycin and other usual antibiotics against the studmicroorganisms. Results: All sixty MRSA strains were multiply resistant to other antimicrobial agents, but 100% of MRSA strains were susceptible to pristinamycin (MIC range: 0.125-1㎎/L). All of fifty PRSP strains were multiple resistant to other antimicrobial agents but 100% PRSP strains were susceptible to pristinamycin (MIC range: 0.125-1㎎/L). Twenty-seven strains of forty H. influenzae strains were β-lactamase positive, and 95% (38/40) of H. influenzae strains were susceptible to prisitinamycin (MICrange : 0.015-4㎎/L) . Conclusion : Pristinamycin demonstrated the highly active. in vitro antimicrobial activities against MRSA. PRSP. and H.influenzae isolated so it might be an effective oral therapeutic agent for treating patients with mild infection due to those organisms or on the outpatient setting.

      • PCR과 SDS-PAGE를 이용한 Bifidobacteria의 동정

        박시홍,송희성,이지연,김해영 경희대학교식량자원개발연구소 2005 硏究論文集 Vol.24 No.-

        SDS-PAGE를 이용한 단백질 패턴의 분석결과, 같은 종의 Bifidobacterium은 동일한 단백질 패턴을 보이며, 다른 종의 Bifidobacterium은 서로 다른 패턴을 보이고 있는 것을 확인하였다. 따라서 SDS-PAGE를 이용한 whole cell protein 패턴 분석으로 Bifidobacterium을 간편하고 빠르게 동정할 수 있는 가능성을 보였다. DNA homology 98% 이상으로 PCR에 의해 동정에 어려움이 많았던 B. catenulatum, B. Pseudocatenulatum group, B. animalis을 SDS-PAGE로 확인한 결과, B. catenulatum과 B. pseudocatenulatum, B. animalis는 뚜렷한 단백질 패턴의 차이를 보임으로써 구별이 가능했다. PCR 수행 시 primer제작은 기존에 보고된 것과 NCBI blast program을 통하여 제작을 하였으며, 그 결과 B. longum, B. bifidum, B. adolescentis 3종류의 종에서만 특이적으로 band가 나타나는 것을 확인할 수가 있었다. 본 실험에서는 SDS-PAGE와 PCR을 이용한 균주 동정법으로 신속하고 정확하게 Bifidobacterium을 탐색할 수 있었으며, 발효유 제조나 의약품 제조 등 산업적으로 이용 될 수 있을 것이다 (Mitsuoka, 1984). Bifidobacterium is a Gram-positive obligate anaerobic bacterium which is able to change cellular shape by nutritional conditions and dominant species in intestinal microflora of human. In order to identify Bifidobacteria spp. in human intestine, PCR and SDS-PAGE of whole cell proteins were used. Species-specific primer sets based on the 16S rRNA, 16S-23S intergenic spacer and heat shock protein genes of three Bifidobacteria spp. were constructed using NCBI blast program (Bifidobacteria adolescentis, B. longum and B. bifidum). PCR products using each primer sets showed the same sizes of expected target genes. From the SDS-PAGE of whole cell proteins in bifidobacteria, profiles of SDS-PAGE between 13 type strains showed distinct differences. These methods will be useful for monitoring and evaluating Bifidobacteria spp. in human intestine microbial population.
