본 연구에서는 PCR을 이용하여 국내시장에 유통중인 원료콩과 가공식품에 epsps 또는 pat 유전자가 삽입된 유전자재조합 콩(GMS)의 사용여부를 모니터링하였다. 이러한 GMS의 검출을 위해 3쌍의 primer set을 제작하였고, 각각의 primer들은 GMS에 삽입된 유전자와 특이적으로 반응하여 PCR산물을 생성하였다. 2001년 표시제가 시행되기 이전에 생산된 총 가공식품과 이후의 제품에 대해 각각 모니터링을 수행하였으며, 표시제 이전에 생산된 제품의 경우 대부분의 미국산 원료에서 esps가 삽입된 GMS가 검출되었으나, 표시제 이후에는 검출되지 않았다. A method using PCR was developed for the monitoring of genetically modified soybean (GMS) and GMS derived foods utilized in the market. We designed 3 pairs of specific oligonucleotide primers based on epsps and pat inserted in GMS and ferritin gene as internal standards. Template DNAs isolated from soybean and processed foods were used for multiplex PCR with 3 primer sets. PCR, used with specific primer sets for GMS detection, showed the amplified DNA fragments with GMS template DNA. In this study, GMS containing epsps was detected from soy processed foods manufactured before GM food labeling system, however, GMS containing epsps or pat was not detected from soy processed foods manufactured after GM food labeling system.

Pesticides were extracted from samples with 70% acetone and methylene chloride in order, and then cleaned up via open-column chromatography apparatus packed with fiorisil, and finally analyzed simultaneously the organophosphorus pesticides using GC/NPD, Ultra-2 and Ultra-1 fused silica capillary columns were used to separate and identify the products. Recovery of most analytes from soybean sample, taken from pesticide residues well, was greater than(80%) for all except(6) analytes. This method can simultaneously determine multiple pesticides with a high degree of accuracy and precision.

The genus Nola (Nolidae, Nolinae) was established by Leach (1815), with the Noctua palliola Denis & Schiffermüller, 1775 (a junior subjective synonym of Phalaena cucullatella Linnaeus, 1758) from Vienna, Austria. Nola comprises over 200 species: Africa and western Palearctic approximately described 100 speices (Hacker et al., 2012); Oriental and Eastern Palearctic regions have over 100 species (László et al., 2010; Sasaki et al., 2011; Kononenko and Pinratana, 2013). Two species of the genus Nola Leach; Nola euryzonata (Hampson, 1900) and Nola lucidalis (Walker, 1865), reported for the first time in Laos. Illustrations of adults and genitalia of all the examined species are provided.

This study was carried out to test the body fat breakdown during topical seaweed extract treatment and in combination with the aerobic exercise. Of 20 female obesity subjects, ten treated a cream types of seaweed extract(control group) and ten treated a placebo cream(placebo group). Topical treatment of each sample was designed for 4 weeks, and treated with 2 times a day about 10ml on the abdomen and the thigh, respectively. All subjects were participated aerobic dance half hour a day and four times a week. After 4 weeks of topical treatment and exercise, they were measured body fat, skinfold thickness, body circumference. Then venous blood samples were taken and analyzed blood cells, serum enzymes, and serum lipids. There were reduction of body weight, % of body fat, antebrachium, brachium, chest, waist, thigh circumference and abdomen thickness between pre and post treatment in both group. Especially, body weight and % of body fat significantly reduced in the subjects treating the seaweed extract than those treating the placebo. There were significant decrement in total cholesterol and LDL whereas increment in HDL and TBIL in the control group, but no significant difference in the placebo group. In conclusion, there were 7.6% of body fat reduction during 4 weeks of aerobic exercise and 21% of body fat reducement in combination of topical seaweed treatment and exercise, respectively. These results suggest that the topical treatment of seaweed extract should be very effective for fat breakdown. Especially, the body fat breakdown maximized in the combination with the topical seaweed extracts treatment and the aerobic exercise.

본 연구는 김치가 노화와 직접적인 관련이 있는 유리기 생성 및 항산화 효소활성에 미치는 영향을 살펴보기 위하여 배추김치, 배추갓김치 그리고 갓김치를 식이중량의 5% 첨가하여 실험식이를 제조하여 이를 노화촉진쥐인 SAMP8에게 1년간 섭취시켰다. 총유리기, OH radical, H_2O_2농도 그리고 TBARS 농도 모두 가령에 따라 증가하였으며, 김치섭취시 유의적으로 감소되었다(p<0.05), 김치군에 있어서 생성된 유리기를 제거하기 위해 항산화계 효소인 SOD, catalase, GSH-px 그리고 GSH/GSSG는 모든 김치군에서 유의적으로 증가 하였다(P<0.05). 따라서 김치섭취는 먼저 가령에 의해 생성되는 유리기의 생성은 억제시키면서, 둘째 이를 제거하기 위한 항산화계 효소 활성은 더욱 활성화시키므로써 항노화 기능을 발휘한다고 생각된다. 김치종류 중에서는 배추갓김치와 갓김치가 배추김치보다 유리기 생성을 억제하고, 항산화계 활성을 증진시킨 것으로 보아 이들의 항노화 효과가 클것으로 생각된다. This study was performed to investigate the effect of kimchi intake on antiaging characteristics in the brain of senescence-accelerated mouse (SAM) in terms of free radical production and anti-oxidative enzymes. Two hundreds twenty SAM (20 mice) were divided into four groups and fed kimchi diet for 12 months. Experimental groups were kimchi free AIN-76 diet (control) group, Korean cabbage kimchi diet (KCK)group, 30% mustard leaf added Korean cabbage kimchi diet (MKCK) group, and mustard leaf kimchi diet (MLK) group. Concentrations of total free radical, OH radical and H_2O_2 of control group increased up to 123%, 262% and 174% of initial value (p<0.05) after one year. Increase in free radical production in kimchi groups due to aging was decreased by kimchi feeding. Among kimchi groups. MKCK and MLK groups showed greater inhibiting effect against free radical production than KCK. The concentration of TBARS in the bruin of control group also significantly increased up to 362% of initial value as aged (p<0.05) and production of TBARS in kimchi groups were decreased. When the activities of Cu, Zn-SOD, Mn-SOD, GSH-px and catalase of kimchi groups were compared to those of control at the same experimental period, anti-oxidative enzyme activities of kimchi groups were lower than those of control (p<0.05). But GSH/GSSG in kimchi groups were higher compared to control. In conclusion, decrease in free radical production and increase in anti-oxidative enzyme activities were observed from kimchi groups suggesting that kimchi might have important role on retarding aging. Among kimchi variety tested in this experiment, MKCK and MLK seem to have greater effect on inhibiting free radical production and increasing anti-oxidative enzyme activities than KCK.

In spite of labor saving in rice cultivation, the main factors preventing the enlargement of the direct wet seeding culture are unstable seedling establishment and greater susceptibility to lodging. In order to solve these problems, developed rice-seed pellets were investigated on sowing and early growth characteristics of seed pellet. Seed shifting, flooding seedling, and lodging of seeding percentage of pellet seed were lover than pregerminated or dry seed. Soil thickness covering seed of pellet seed was 2 ㎜ and shifting width of seed of that was 1.5 ㎝. Establishment percentage of pellet seed was the highest in 0 ㎝ of seeding depth. Early plant height, root length, number of leaf and root of pellet seed with seeding time were similar to those of dry seed.

Environmental values, through a process of tension and adjustment, can come to an important and intergrated part of our sociopolitical value structure. Environmentalists frequently reject goals such as economic growth, indiscriminate technological progress, and national security conceived in terms of greater poplulation. Economic growth and technological progress, however, must rest on the bedrock of sustainability(sustainable development in 'Our Common Fuuuture') which is dependent upon each nation achieving its full economic potential, while at the same time enhancing the environmental resources upon which development must be based. Economic reasoning is concerned primarily with voluntary exchange. Anything that is relevant to the analysis of a policy problem can be defined as either a cost a benefit to human individual preference satisfaction. The trade-off between cost and benefit is purpoted to indicate the most rational and moral policy choice for the decision maker. Despite public approval of environmentalism, the political impact may still be restricted in several ways. Environmentalism has become a consensual value in Korean politics but it is only in a passive way and it may not always be translated into the political or policy impacts.

한혜원,김재연,송영천,김승은,유성길 한국병원약사회 2009 병원약사회지 Vol.26 No.1

Abstract: In organ transplant patients, the opportunity of fungi infections such as invasive aspergillosis increase by use of immunosuppresant drugs and voriconazole is recommended as primary treatment drug. When voriconazole is administered with cyclosporine(CsA) or tacrolimus(FK506), caution about increment of blood CsA or FK506 concentrations that caused by the change of CYP3A4 activity is required but few domestic cases of interaction were reported yet, The purpose of this study was to assess the effect of voriconazole on the blood CsA or FK506 concentrations in transplant recipients and the factors of recipients that have an effect on the results. 25 transplant recipients who were administered voriconazole with CsA or FK506 from January 1 of 2006 to August 17 of 2008 in Asan Medical Center were objects (12 patients on CsA coadministration arm - 9 males, 3 females; 41~62years;2 liver, 2 kidney, 3 bone marrow, 5 heart transplant recipients, and 13 on FK506 coadministration arm - 7 males, 6 females;26~65years; 10 liver, 2 kidney, 1 heart transplant recipients). Blood CsA or FK506 concentrations before and after coadministration of voriconazole, and maximum concentration in one month from the first day of coadministration were monitored retrospectively. In most cases CsA or FK506 were administered as recommended doses regardless of coadministration of voriconazole, and blood concentration increased from 239.42±126. 77ng/ml to maximum 411.92±225. 76ng/ml in CsA coadministration arm(p=0.003), and from 7.72±2.79ng/ml to maximum 19.16±9.35ng/ml in FK506 coadministration arm(p=0.003). Gender, age, and the kind of transplant organ did not affect to the change of blood concentration in both two arms. In consequences, administration of voriconazole could affect on the blood CsA or FK506 concentration, and in cases of administra tion of voriconazole in transplant recipients treated with CsA or FK506, close monitoring and dose adjustment is needed.
