영지버섯 단백다당체 GLB-A의 UA에 대한 보호효과

정경수,오정연 충남대학교 약학대학 의약품개발연구소 1997 藥學論文集 Vol.13 No.-

In the previous study we described the antitumor and immunomodulatory activities of GLB-A. an acidic protein-polysaccharide fraction of the growing tips of Ganoderma lucidum. In this study we used flow cytometry to elucidate the protective effect of GLB-A on the splenocytes and thymocytes of BALB/c mouse exposed to ultraviolet irradiation. GLB-A increased the thymocytes of BALB/c mouse exposed to ultraviolet irradiation. GLB-A increased the viability of the UV-irradiated splenocytes in a dose-dependent pattern (17.1% increase at 200 ㎍/㎖) and its protective effect was remarkable only during UV irradiation. When the UV absorption spectrum was analyzed, GLB-A showed a maximal absorbance at 257 nm. Based on these observations, the protective effect of GLB-A against UV radiation seemed to originate at least partly from its UV-absorbing property.

Introduction: Hyperreninemic hypoaldosteronism in septic shock patients has been described. However, little is known about the serial plasma renin activity regarding septic shock patients. The present study investigated the relationship between the plasma renin activity and clinical course in septic shock patients. Method: The study was conducted retrospectively in a 30-bed medical intensive care unit of Yonsei University College of Medicine between August 2008 and January 2009. One hundred seven patients aged over 18 years admitted to ICU with septic shock were enrolled. Blood sample was taken to measure basal plasma renin activity (PRA), plasma aldosterone concentration (PAC) and plasma cortisol level at intensive care unit (ICU) admission on day 0 (D0), day 1 (D1), day 3 (D3) and day 7 (D7) after ICU admission. Results: 59 (55.1%) were survivors and 48 (44.9%) were non-survival at 28 day after ICU admission. There was no difference between demographic factors, PRA, PAC, PAC/PRA, and cortisol level on D0. Level of PRA in survival was 9.76±12.35, 14.79±14.53, 17.67±15.54 and 15.62±14.89ml/μl/hr on D0, D1, D3 and D7. (mean±SD). On the other hand, Level of PRA in non-survival was 8.93±10.84, 8.01±9.71, 7.98±11.31 and 4.65±7.55ml/μl/hr on D0, D1, D3 and D7. (mean±SD). Analysis of variance with serial measurements showed significant changes in PRA between two groups during the first week after the onset of septic shock (p<0.05). Conclusion: Decrease in serial plasma renin activity is maybe associated with mortality at 28 day after ICU admission.Introduction: Hyperreninemic hypoaldosteronism in septic shock patients has been described.

韓國産 擔子菌類의 抗菌成分에 관한 硏究 (I) : 10種의 擔子菌에 대한 抗菌成分 檢索 A screening test for the antibiotic activities of ten basidiomycetous fungi

鄭敬壽,柳柄泰,金炳珏 충남대학교 약학대학 의약품개발연구소 1985 藥學論文集 Vol.1 No.-

The ether, methanol, and physiological saline extracts of the dried carpophores of ten basidiomycetous fungi, which were collected in the conifer woods of Chungnam National University at Taechon, were subjected to an antibiotic activity test by disc-plate method. Among them, the methanol extracts of Marasmius maximus, Hirschioporus abietinus, and Russula sanguinea and the the ether extracts of M. maximus and H. abietinus showed antibiotic activities against Sarcina lutea; and the methanol and ethanol extract of M. maximus showed antibiotic activity against Staphylococcus aureus. None of the extracts, however, showed any activity against gram negative bacteria, Serratia marcescens and Proteus vulgaris.

밀착조임 볼트체결에 따른 판폭두께비가 큰 변단면 프레임의 구조성능에 관한 실험적 연구

정경수,전배호,박만우,도병호,Chung, Kyung-Soo,Jeon, Bae-Ho,Park, Man-Woo,Do, Byung-Ho 한국강구조학회 2012 韓國鋼構造學會 論文集 Vol.24 No.3

저층 장스팬 철골프레임에는 강재절감을 위해 휨모멘트 저항을 극대화 한 판폭두께비가 큰 변단면 부재를 이용한 PEB시스템을 사용하고 있다. 또한, 밀착조임 볼트접합은 완전조임 볼트접합에 비하여 공사비 절감과 시공용이성의 장점을 지니고 있다. 이에 본 연구에서는 밀착조임 볼트접합으로 이루어진 엔드플레이트형 접합형식에 판폭두께비가 큰 변단면 철골프레임의 실대형 실험을 행하였다. 변수로는 볼트체결방법과 재하하중방법이다. 프레임위치별 구조적 거동에 대해서 실험결과를 분석하고, 하중-변위관계에 대해서 해석결과와 비교하였다. 또한, 현장에서 밀착조임 볼트체결에 대한 볼트축력 도입과 사용성을 평가하였다. Current trends in steel construction include using tapered, non-compact sections to minimize the use of excess material as much as possible by choosing the cross-sections instead of the classical approach of using prismatic members. In addition, snug conditions, especially the end-plate type, have the advantage of incurring less construction costs and shorter assembly times as opposed to full pre-tensioned conditions. On the other hand, it is important to predict the collapse of the PEB system due to over-loading. Large-scale tests of tapered steel portal frames with non-compact sections were conducted. The primary test parameters included the bolt connection method and the loading condition (vertical and horizontal load). The test results on initial stiffness and load capacity were investigated. Furthermore, comparisons between the analytical and experimental data for load-displacement curves were initiated. In addition, we evaluated the applicability of a snug bolt for the PEB frame in the field.

일정축력하에 고온을 받는 고강도 콘크리트 충전강관 기둥의 구조적 거동에 관한 연구

정경수,최인락,김도환,김진호,Chung, Kyung Soo,Choi, In Rak,Kim, Do Hwan,Kim, Jin Ho 한국강구조학회 2013 韓國鋼構造學會 論文集 Vol.25 No.1

구조, 시공 및 내화측면에서 우수한 콘크리트충전강관(CFT)부재에 대해서 구성재료의 강도가 높은 경우 즉, 콘크리트 압축강도가 100MPa 이상이면서 강관의 항복강도가 650MPa 이상인 경우에 대한 내화성능 평가실험 및 해석적 연구는 미비한 실정이다. 본 연구에서는 이러한 부재에 대해서 내화성능 거동을 파악하고자 ${\Box}-400{\times}400{\times}15$, 부재길이 3,000mm인 실물대 중심재하 내화실험을 행하였다. 실험변수는 중심축력을 5,000kN과 2,500kN로 하였다. 실험결과, 고강도 콘크리트의 폭렬 및 콘크리트 내부 균열에 의하여 축하중이 클수록 조기에 내력을 상실하였다. 또한, 유한차분법과 변형률적합조건을 이용한 비정상온도해석 및 응력해석을 수행하였으며, 고강도 재료모델은 Eurocode모델을 이용하였다. 해석모델은 시간-축변위 관계를 합리적으로 예측할 수 있었다. Fire-resistant (FR) test data for a square concrete-filled steel tube (CFT) columns consisting of high-strength steel (fy>650MPa) and high strength concrete (fck>100MPa) under axial loads are insufficient. The FR behavior of square high-strength CFT members was investigated experimentally for two specimens having ${\Box}-400{\times}400{\times}15{\times}3,000mm$ with two axial load cases (5,000kN and 2,500kN). The results show that the FR performance of the high-strength CFT was rapidly decreased at earlier time (much earlier at high axial load) than expected due to high strength concrete spalling and cracks. In addition, a fiber element analysis (FEA) model was proposed and used to simulate the fiber behaviour of the columns. For steel and concrete, the mechanical and thermal properties recommended in EN 1994-1-2 are adopted. Test results were compared to those of numerical analyses considering a combination of temperature and axial compression. The numerical model can reasonably predict the time-axial deformation relationship.

판폭두께비가 큰 변단면 휨부재의 구조성능에 관한 실험적 연구

정경수,전배호,박만우,도병호,Chung, Kyung-Soo,Jeon, Bae-Ho,Park, Man-Woo,Do, Byung-Ho 한국강구조학회 2011 韓國鋼構造學會 論文集 Vol.23 No.3

저층 장스팬 철골프레임에는 강재절감을 위해 휨모멘트 저항을 극대화 한 판폭두께비가 큰 변단면 부재를 이용한 PEB시스템을 사용하고 있다. 과다한 외력에 의해 PEB시스템의 붕괴에 대한 안정성을 파악하기 위해서는 변단면 부재의 좌굴거동에 관한 실험 및 해석적 예측은 중요하다. 이에 본 연구에서는 변단면의 판폭(춤)두께비(d/t)와 변단면비를 주요 변수로 한 변단면 부재에 대한 실대형 실험을 행하였다. 현행 설계기준, 수정된 Yoda 모델을 이용한 소성힌지해석 및 유한요소해석으로 예측한 초기강성, 내력 및 모멘트-회전각관계에 대해서 실험결과와 비교하였다. The current trends in steel construction intend to use tapered sections to minimize as much as possible the use of excess material. This can be done by choosing the cross-sections to be as economical as possible, leaving the classical approach of using prismatic members. In addition, it is important to predict the buckling behavior of tapered member with large depth-to-thickness ratio in order to prevent the collapse of PEB system subjected to overloads. An experimental investigation of buckling behavior of tapered beam was presented. The primary test parameter was depth-to-thickness ratio and taper ratio. Using initial stiffness and load-carrying capacity proposed by current provision, the simple plastic hinge method using modified Yoda's model and finite element analysis, the prediction of a moment-rotation curve of linearly tapered member was presented. Moreover, comparisons between analytical and experimental data for moment-rotation curves were accomplished.
