강어진,이상선,양차범,신현경 한국식품영양학회 1998 韓國食品營養學會誌 Vol.11 No.5

한국에서 주로 섭취되고 있는 주요 식이섬유질원으로서 장내 유익균의 생육을 촉진한다고 알려진 사과, 미역, 쑥, 머위를 천연 형태로 건조분말화하여 식이내에 5%, 15%가 되게 첨가한 후 노화가 진행된 흰쥐에게 4주간 급여하였다. 그 결과 β-glucuronidase는 셀를로스군과 미역 15% 첨가군에서 가장 낮은 활성을 나타냈으며 β-glucuronidase의 경우는 쑥 15% 첨가군에서 유의적으로 현저한 증가를 보였다. 부패산물인 인돌 함량 변화는 쑥 섭취군에서 현저하게 낮은 경향을 보여 β-glucuronidase와는 다른 양상을 보였다. 수분함량은 미역섭취군과 쑥5%, 머위15% 섭취군에서 높았으며 pH는 쑥 15% 섭취군이 가장 낮은 값을 보여주었다. 쑥 15% 섭취군이 장내균총 조성을 개선시킬 수 있을 것으로 보고되어 그 유의성을 밝히고자 하였으나 본 실험에서는 부패산물, 유해효소등과 장내균총의 조성과의 뚜렷한 관계는 발견하지 못하였다. This study was performed to investigate the influence of various dietary fiber sources in Korea for activities of bacterial enzymes (β-glucosidase, β-glucuronidase) and amounts of putrefactive product (indole) in aged rats β-Glucosidase activity in the intestinal content was significantly lower in the sea mustard 15% group than in other groups whereas the activity of β-glucuronidase was higher in the mugwort 15% group than other experimental groups. The amount of indole and pH in the intestinal content of aged rats were significantly lower in mugwort groups than in other groups.

유두상 섬유탄력종은 주로 심장판막에 발생하는 원발성 종양으로 심장종양 중 두 번째로 많은 양성종양이나 전체적으로 그 빈도는 매우 드물다. 78세 여자 환자가 흉부 불편감을 주소로 내원해서 대동맥판막에 위치한 유두상 섬유탄력종이 발견되어 개심술 하에 대동맥판막의 손상 없이 종양을 제거하였기에 문헌고찰과 더불어 이를 보고하는 바이다. Cardiac papillary fibroelastoma is the rare primary cardiac tumor, though it is the second most common benign cardiac tumor. It usually involves the cardiac valve. Papillary fibroelastoma of the aortic valve was found in a 78-year-old woman with chest discomfort and it was excised without valvular injury under cardiopulmonary bypass. Thus we report the present case with relevant review of the literatures.

1995년 서울지역 거주자에서 발생한 Plasmodium Vivax에 의한 Malaria 1예

김영선,박기령,어은경,최진혁,이정수,정화순 梨花女子大學校 醫科大學 醫科學硏究所 1996 EMJ (Ewha medical journal) Vol.19 No.2

Malaria has a wordwide incidence of more than one thousand to three thousand million clinical cases and results in approximately 200 to 300 million deaths per year. Although Korea was an endemic area of Malaria, it was nearly eradicated from the country. However, indigenous cases of malaria have been reported since 1994. Recently, we experienced a case of Plasmodium vivax infection in a resident of Seoul. A 25-year old young man who had no history of being abroad, blood transfusion nor parenteral use of drug visited our hospital due to fever and chill for 4 days. A peripheral blood smear demonstrated Plasmodium vivax infection. He was treated with hydroxychoroquine and premaquine without relapse.

<P><B>Abstract</B></P> <P>The endangered Black-faced Spoonbill <I>Platalea minor</I> has experienced drastic reductions in population size, geographic distribution, and habitat availability throughout East Asia. In the present study, we examined population genetic structure and genetic diversity of Black-faced Spoonbills inhabiting five sites off the west coast of South Korea encompassing a few of its major breeding sites. Ten microsatellite loci and the mitochondrial sequence were used to assess patterns of genetic variation based on 63 individuals. Three ND2 haplotypes were found among 61 individuals; the remaining two were identified as Eurasian Spoonbills, revealing an unexpected hybridization between these two species having different ecological niches in South Korea—the Eurasian Spoonbill overwinters in inland areas, whereas the Black-faced Spoonbill inhabits coastal areas during the summer. Analyses of microsatellite variation revealed no discrete population structure among the five breeding sites but very weak genetic differentiation among geographically distant regions. Assignment tests identified several possible migrants among sites. Our findings suggested that Black-faced Spoonbills from the five breeding sites could be managed as a single population and highlighted the importance of conserving the populations from Maedo, Suhaam, and Namdong reservoir, which are geographically close and have retained high levels of genetic diversity and large populations.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Ten polymorphic microsatellite loci and the mitochondrial DNA sequence were used to assess genetic diversity and structure. </LI> <LI> No discrete population structure among the five breeding sites in South Korea but very weak genetic differentiation among geographically distant regions. </LI> <LI> Black-faced Spoonbill individuals from the five breeding sites could be managed as a single population in South Korea. </LI> <LI> Unexpected hybridization between the Eurasian Spoonbill and the Black-faced Spoonbill was observed in our genetic studies. </LI> </UL> </P>

Lee, Jin Wook,Eo, Hyun Ji,Park, Gwang Hun,Song, Hun Min,Woo, So Hee,Kim, Mi Kyoung,Eom, Jung Hye,Lee, Man Hyo,Lee, Jeong Rak,Koo, Jin Suk,Jeong, Jin Boo The Korea Association of Herbology 2014 大韓本草學會誌 Vol.29 No.2

Objectives : Reactive oxygen species (ROS) are involved in a wide spectrum of diseases including chronic inflammation and cancer. In this study, we investigated the antioxidant activities and anti-inflammatory effects of the extracts from the herbal teas such as Lonicera japonica Thunberg (L. japonica), Chrysanthemum morifolium Ramat (C. morifolium), Mentha arvensis L. (M. arvensis), and P.rhizoma. Methods : Anti-oxidant activity was evaluated using DPPH radical scavenging assay and $Fe^{2+}$ chelating assay. And DNA cleavage assay was performed to evaluate an anti-oxidative effect. Anti-inflammatory effect was performed using NO generation assay and western blot in LPS-stimulated RAW264.7 cell line. Results : L. japonica scavenged DPPH radical by 9.8% at 12.5 ${\mu}g/ml$, 24.8% at 25 ${\mu}g/ml$, 34.3% at 50 ${\mu}g/ml$, 61.1% at 100 ${\mu}g/ml$ and 75.8% at 200 ${\mu}g/ml$, respectively. In addition, C. morifolium and M. arvensis removed DPPH radical by 15.6% and 10.4% at 12.5 ${\mu}g/ml$, 34.8% and 22.8% at 25 ${\mu}g/ml$, 66.9% and 43.3% at 50 ${\mu}g/ml$, 87.4% and 69.1% at 100 ${\mu}g/ml$, and 92.1% and 73.2% at 200 ${\mu}g/ml$, respectively. However, P. rhizoma did not affect on DPPH radical scavenging. The $Fe^{2+}$ chelating activity was highest in L. japonica, but lowest in P. rhizoma among the herbal teas. In addition, the extracts from L. japonica, C. morifolium and M. arvensis inhibited oxidative DNA damage via its anti-oxidant activity. In anti-inflammatory effect, the extracts from C. morifolium inhibited NO production. In addition, it suppressed the $NF-{\kappa}B$ signaling pathway in LPS-stimulated RAW 264.7 cells. Conclusions : Together, this study indicates that L. japonica, M. arvensis and C. morifolium possess the protective effect against the oxidative DNA damage. Furthermore, C. morifolium exerts an anti-inflammatory effect.

<P><B>Abstract</B></P> <P>To develop tritium breeding technology for a Fusion Reactor, Korea has participated in the Test Blanket Module (TBM) program in ITER. The He Cooled Ceramic Reflector (HCCR) TBM consists of functional components such as First Wall (FW), Breeding Zone (BZ), Side Wall (SW), and Back Manifold (BM) and it was designed based on the separate analyses for each component in 2012. Based on the each component analysis model, the integrated model is prepared and thermal-hydraulic analysis for the HCCR TBM is performed in the present study. The coolant flow distribution from BM and SW to FW and BZ, and resulted structure temperatures are obtained with the integrated model. It is found that the non-uniform flow rate occurs at FW and BZ and it causes excess of the design limit (550°C) at some region. Based on this integrated model, we will perform the design optimization for obtaining uniform flow distribution for satisfying the design requirements.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Integrated analysis is performed with the conventional CFD code (ANSYS-CFX). </LI> <LI> Overall pressure drop and coolant flow scheme are investigated. </LI> <LI> Manifold design is being performed considering flow distribution. </LI> </UL> </P>
