The National Standard Food Composition Table published by the Rural Development Administration (RDA) provides the foundations in research, nutrition monitoring, policy and dietary practices in Korea. This databases consists of several sets of data including food descriptions, nutrients, portion weights, and source of data. The National Standard Food Composition Table have been published since 1970 and, recently, new version (8th edition) of Food Composition Table which has quantitative and qualitative nutrient data is released in 2011. In addition, the User-friendly Food Composition Table is divided into adult, children, and elderly categories depending on the subjects because we need different nutrients according to various ages. The Tables of Food Functional Composition is firstly edited in 2009. RDA published the minerals and fatty acids composition table, tables of amino acid, fat-soluble vitamin composition table, and the cholesterol table. The resulting database will be widely used. The users of the databases are from diverse fields, includeing federal agencies, the food industry, health professionals, restaurants, software application developers, academia and research organizations, international organizations, and foreign governments ect. Therefore, consistent improvements of the database is important, so that people can better address such health challenges by providing reliable and accurate data.

RAPD Marker를 이용한 Zoysiagrass 수집계통과 종간교배 계통의 유전적 다양성 분석

金斗煥,毛淑淵,林星希 建國大學校 附設 農業資源開發硏究所 1997 農資源開發論集 Vol.19 No.-

ABSTRACT: RAPD markers were analyzed with zoysiagrass accessions and their hybrid lines in order to detect the genetic variation, and the following results were obtained.1. CTAB extraction method produced more and purer DNA than SDS method. RAPD reaction conditions were optimized as follows: 10ng template DNA, 270nM primer, 200μM each of dATP, dGTP and dTTP, 0.5μ unit dynazyme and 10x buffer brought to 15μl final volume with distilled water. The adequate annealing temperature was 36℃ and time was 30sec. Fifty cycles of amplification produced the best RAPD band patterns.2. Electrophoresis of PCR-products produced more polymorphic bands with polyacrylamide gel than with agarose gel. 3.The grouping patterns of zoysiagrass lines at dendrograms by RAPD markers were very different from the expected grouping pattern, and that was probably because of natural interspecific crossings for the long period. Therefore, the classification of the species within Zoysia genus will not be any longer meaningful and zoysiagrasses should be classified by the cultivar names or morphological characteristics such as leaf width.4. The zoysiagrass lines collected from Japan and Korea were belonged to the completely different groups at the dendrograms. The reason is expected to be the genetic drift due to geographical isolation.

최종당화산물이 혈관평활근세포 증식에 미치는 영향 및 그 기전

송진영,임성희,서지영,조영중,유형준,박성우,임자혜 대한당뇨병학회 2002 Diabetes and Metabolism Journal Vol.26 No.2

연구배경:혈관평활근세포의 증식은 죽상경화증의 주된 변화로 당뇨병과 동반된 죽상경화증에서도 관찰된다. 최종당화산물(AGE)은 NO와 결합함으로써 이의 혈관평활근세포 증식 억제 작용을 차단한다고 알려져 있으나. 혈관평활근세포에도 최종당솨산물에 대한 수용체가 발견되었음에도 불구하고 최종당화산물이 혈관평활근세포의 증식에 직접 미치는 영향 및 기전에 대하여는 잘 알려져 있지 않다. 본 연구에서는 최종당화산물이 백서 대동맥에서 분리 배양한 혈관평활근세포 증식에 미치는 영향 및 그 기전을 알아 보고자 하였다. 방법:혈관평활근세포는 male Sprague­Dawley 백서의 대동맥에서 분리하여 10% FBS­DMEM 내에서 배양하였고, 세포 증식 실험은 24­well plate에 well당 1×10⁴세포를 0.1% FBS­DMEM(with or without AGE­BSA, anti­AGE antibody, MAP kinase inhibitor, antioxidants)내에서 배양하여 48시간후 MTT assay로 세포 증식을 측정하였다. 결과:AGE­BSA를 2.5, 5.0㎍/mL 농도로 첨가한 경우 혈과평활근세포 수는 AGE­BSA를 가하지 않은 대조군에 비해 1.5, 1.6배 증가되었다. 이러한 AGE­BSA에 의한 혈관평활근세포 증식 촉진 효과는 anti­AGE antibody(100㎍/mL), MAP kinase 억제제인 PD98509(50μM)및 항산화제인 N­acetylcysteine(1μM)이나 butylated hydroxyanisole(10μM)에 의해 차단되었다. 결론:이러한 결과는 AGE가 혈관평활근세포에서 산화 스트레스의 변화를 초래하고 MAP kinase 경로를 통해 혈관평활근세포의 증식 및 죽상경화증의 발생에 기여할 가능성을 뒷받침한다. Background : Diabetes mellitus is an epidemiologically proven risk factor for atherosclerosis. Advanced glycation end products (AGE) have been implicated in the pathogenesis of many diabetic vascular complications. AGE not only change the physicochemical properties of proteins, but also AGE on the vascular smooth muscle cells (VSMCs) have not been fully explained despite of presence of an AGE-receptor on the VSMCs. Methods : In order to test whether AGE promotes atherosclerosis by stimulation of the growth promoting signal transduction pathways in the VSMCs, the proliferation of rat aortic VSMCs cultured in the presence of AGE-BSA with/without anti-AGE antibodies, the MAP kinase inhibitor and antioxidants was measured. The VSMCs (1x10^4 cells in 24-well plates) isolated from the aorta of Sprague-Dawley rats were incubated for 48 hours and the proliferation was assessed by a MTT assay. Results : AGE-BSA increased the proliferation of rat aortic VSMCs by 1.5~1.6 fold at the ㎍/mL level. The stimulatory effect of AGE-BSA (5㎍/mL) was blocked by the anti-AGE antibodies (100 ㎍/mL). PD98059 at 50? inhibited the AGE-BSA-induced VSMC proliferative response of the VSMCs to AGE. AGE-BSA-induced VSMC proliferation was also attenuated by N-acetylcysteine (1?) and butylated hydroxyanisole (10?), implying that increased intracellular oxidative stress might be also involved in the proliferative response to AGE. Conclusion : These results suggest AGE play a role in diabetic atherosclerosis by stimulating of the growth promoting signal transduction pathways in the VSMCs (J Kor Diabetes 26:91~99, 2002).

당뇨병유발 백서에서 홍삼의 지질 과산화에 대한 효과

진희종,임성희,임자혜 대한당뇨병학회 2002 Diabetes and Metabolism Journal Vol.25 No.5

연구배경:당뇨병에서 산화 스트레스의 증가에 따른 지질 과산화는 혈관 합병증의 발생과도 연관된다고 알려져 있다. 당뇨병에서 증가된 산화 스트레스가 산화 손상 및 합병증 발생의 중요한 기전이라면 항산화제 투여로 당뇨병의 합병증이 예방되거나 진행이 지연될 가능성이 있다. 최근 홍삼이 내피세포에서 NO 합성을 증가시키고 하이드록시 라디칼과 반응하여 제거함으로써 유리 라디칼 연쇄반응을 억제하는 항산화 작용이 있음이 보고되었다. 본 연구에서는 홍삼이 당뇨병에서 지질 과산화를 억제할 수 있는지 알아 보고자 하였다. 방법:시험관내에서 인지질 리포솜 지질의 철이온에 의한 과산화에 대한 홍삼정(red ginseng extract)의 영향을 알아 보았다. 또한 생체내에서 홍삼이 당뇨병시 지질 과산화에 미치는 영향을 알아 보고자 STZ으로 당뇨병을 유발할 백서에서 홍삼정(1g/L in drinking water)을 12주간 투여한 후 혈장과 간, 신장 및 심장 조직의 지질 과산화물을 측정하여 당뇨병 대조군과 비교하였다. 결과:홍삼정은 in vitro에서 인지질 리포솜 지질의 철이온에 의한 과산화와 저밀도지단백 지질의 구리이온에 의한 과산화를 억제하였다. 혈장 MDA 농도는 STZ­유발 당뇨병군에서 정상 대조군보다 약 2배로 높았고, 12주간 홍삼 투여 당뇨군은 비투여 당뇨군에 비해 유의하게 41%낮았다. 간, 신장 및 심장 조직의 MDA 농도는 STZ­유발 당뇨병군에서 정상 대조군보다 모두 유의하게 높았고, 12주간 홍삼 투요 당뇨군은 비투여 당뇨군에 비해 각각 17%, 14% 및 30% 유의성 있게 낮았다. 결론:본 연구에서는 당뇨병 백서에서 홍삼정을 투여하여 혈장과 간, 신장 및 심장 조직에서 지질 과산화물이 감소함을 관찰하였고, 시험관내에서도 홍삼정이 인지질 리포솜이나 저밀도지단백의 지질 과산화를 억제하는 작용이 있음을 관찰하였다. 이러한 연구 결과는 홍삼이 당뇨병에서 산화적 손상을 줄이고 만성 합병증의 발생이나 진행을 지연시킬 가능성을 시사한다. Background : Diabetes mellitus is postulated to be associated with increased oxidative stress and lipid peroxidation which may contributo to vascular complications. Recently ginseng (Panax) has been shown to have an antioxidant effect by enhancing nitric oxide synthesis in endothelial cells and by directly scavenging hydroxyl radicals. It is unknown whether ginseng might act as an antioxidant against lipid peroxidation in diabetes. Methods : We studied the in vitro effect of red ginseng extract on lipid peroxidation employing phospholipid liposome and low-density lipoprotein (LDL) as a model system. To investigate the in vivo effect on lipid peroxidation in diabetes, we administered red ginseng extract (1g/L in drinking water) to streptozotocin (STZ)-induced diabetic rats for 12 weeks and measured lipid peroxidation products in plasma, liver, kidneys and heart. Results : The Fe^3+ - or Cu^2+ - mediated lipid peroxidation in phospholipid liposome and LDL, measured by the concentration of TBARS, was inhibited in the presence of red ginseng extract. MDA level in plasma measured by HPLC was higher in STZ-induced diabetic rats than in control rats. Plasma MDA level was lower by 41% in red ginseng-treated diabetic rats than in untreated diabetic rats. Tissue MDA levels measured by TBA method in liver, kidneys and heart were higher in STZ-induced diabetic rats than in control rats. In red ginseng-treated diabetic rats tissue MDA levels were lower by 14 ~ 30% than in untreated diabetic rats. Conclusion : We observed that red ginseng extract has an effect in inhibiting lipid peroxidation both in vitro and in STZ-induced diabetic rats. These results suggest that red ginseng might have a beneficial effect in diabetes as an antioxidant against lipid peroxidation and diabetic vascular complications (J Kor Diabetes Asso 25:374~383, 2001).
