  • 솔잎착즙액과 솔잎발효액의 항산화활성을 분석하기 위하여 총 페놀함량, DPPH 라디칼 소거능, 총 항산화능, $ORAC_{ROO{\cdot}}$ 활성, CAC 활성을 분석하였고, 항유전독성을 분석하기 위하여 DNA 손상 억제능을 분석하였으며, 항당뇨효과와 항고혈압 효과를 분석하기 위하여 각각 ${\alpha}$-glucosidase 및 ACE 저해활성을 분석하였다. 총 페놀 함량은 솔잎착즙액(17.3 mg GAE/g)이 솔잎발효액(4.6 mg GAE/g)보다 유의적으로 3.7배 높았으며, 이는 발효가 진행됨에 따라 페놀 성분이 침전된 결과로 보인다. DPPH 라디칼 소거능, 총 항산화능 및 $ORAC_{ROO{\cdot}}$ 활성은 솔잎착즙액이 솔잎발효액 보다 유의적으로 높았다. 즉 1 mg/mL 수준에서 솔잎착즙액과 솔잎발효액의 DPPH 라디칼 소거능은 각각 33.3%, 21.4%로 나타났고, $60{\sim}530{\mu}g/mL$ 농도에서 솔잎착즙액이 솔잎발효액보다 유의적으로 높은 총 항산화능을 나타내었으며, $2{\sim}100{\mu}g/mL$ 농도에서 솔잎착즙액이 솔잎발효액보다 유의적으로 높은 $ORAC_{ROO{\cdot}}$ 활성을 나타내었다. 솔잎착즙액과 솔잎발효액의 CAC 활성은 AAPH 처리군보다 솔잎착즙액 및 솔잎발효액 처리군의 CAC 활성이 농도 의존적으로 증가하였으며, $50{\mu}g/mL$ 농도를 제외하고 두 그룹 간의 유의적인 차이는 나타나지 않았다. 솔잎착즙액과 솔잎발효액의 항산화활성의 상관관계는 총 항산화능과 DPPH 라디칼소거능(r=0.836, p=0.000) 및 ORAC assay(r=0.918, p=0.000) 간의 높은 양의 상관관계가 나타났을 뿐만 아니라 DPPH 라디칼 소거능과 ORAC assay(r=0.909, p=0.000) 간에도 높은 양의 상관관계가 나타나 솔잎착즙액과 솔잎발효액의 높은 항산화활성을 추측할 수 있었다. $H_2O_2$로 유도된 산화적 스트레스에 대한 DNA 손상 억제능은 솔잎착즙액과 솔잎발효액에서 농도의존적으로 증가하였으며, $50{\mu}g/mL$ 농도에서 솔잎발효액이 솔잎착즙액보다 더 높은 경향을 나타내었다. 솔잎착즙액과 솔잎발효액의 항당뇨 효과를 알아보기 위하여 ${\alpha}$-glucosidase 억제능을 실험한 결과 희석배율이 증가할수록 솔잎발효액의 ${\alpha}$-glucosidase 억제능은 급격히 감소하는 반면, 솔잎착즙액은 솔잎발효액보다 높은 활성을 유지하는 것으로 나타났다. 항고혈압 효과 분석을 위한 ACE 저해활성은 2배 희석 시 솔잎착즙액 87.1%, 솔잎발효액 60.0%로 솔잎착즙액의 ACE 저해활성이 높은 경향을 나타내었다. 본 연구를 통해 솔잎착즙액의 다양한 생리활성을 평가하고자 하였으며, 발효가 이러한 생리활성에 미치는 영향을 분석하고자 하였다. 본 연구에서 2년간 발효한 솔잎발효액만을 분석하였고, 발효기간에 따른 활성의 변화를 평가하지 못한 제한점이 있으나 본 연구의 결과는 지금까지 연구가 미흡했던 솔잎착즙액의 생리활성을 보고함으로써 솔잎을 활용한 기능성 소개개발에 유용한 자료로 제안될 수 있을 것이다. 또한 향후 연구에서 솔잎착즙액의 기능성을 증대시킬 수 있는 발효과정에 대한 연구가 수행되어야 할 것이다.

  • Along with recent economic prosperity, the consumption of commercially available beverages has increased dramatically. Beverages on the market are replacing tap water and constituting an increasing large proportion of the total daily fluoride intake. If such changes in the source of fluid intake are not taken into consideration, effective fluoride intake would become difficult in the fluoridated area while there would be confusion as to the basis for proper fluoride supplement prescription in the nonfluoridated area. So, dietary consultation is recommended for every pediatric patient. This study was conducted to provide the reference for dietary consultations on the subject of fluoride supplement using 72 beverages on the market. The fluoride content was measured and the fluoride intake from each age groups was calculated using fluoride ion specific electrode and HMDS-microdiffusion technique. 1. The average fluoride concentration of the 72 beverages was $0.23{\pm}0.10ppm$, from 0.0106ppm to 2.2050ppm. 2. Natural fruit juices, diluted fruit juices, carbonated beverages and mixed beverages showed average fluoride concentration of $0.15{\pm}0.66ppm$, $0.09{\pm}0.11ppm$, $0.15{\pm}0.23ppm$, $0.50{\pm}0.66ppm$, respectively. There were significant differrence between diluted friut juice drinks and mixed beverage, and between the carbonated beverages and mixed beverges(p<0.05). 3. Using available data on the daily total consumption of beverages and the relative consumption of beverages on the market according to age, daily fluoride intake for various age groups was calculated. According to the results, 2 to 3 year-old children need 0.13mgF/day, those between 4 and 6 year-old need 0.15mgF/day, and those between 7 and 10 year-old need 0.17mgF/day.

  • In this biocontrol research, we evaluated disease suppressive effects of antagonistic bacterial strains ISE13 and KJ1R5 against Korean ginseng root rot caused by P. eaetorum. We also examined the effects of nutrient solution in the hydroponic culture system for Korean ginseng on biological activity of the bacterial strains. As results of dual culture tests of the bacterial strains on $V_{8}$ juice agar, the strain ISE13 showed antifungal activity against P. eaetorum and other plant pathogenic fungi, but the strain KJ1R5 did not. When their inhibitory effects against infection of P. eaetorum on the roots grown in either nutrient solution or water were tested, the strains ISE13 and KJ1R5 inhibited the disease severity of Korean ginseng roots only grown with water, compared to buffer-treated, inoculated controls. However, the nutrient solution used for hydroponic cultures of ginseng in pots caused higher levels of disease severity by the strains ISE13 and KJ1R5 from 418.8\%$ to 40.0\%$ and from 24.3\%$ to 45.0\%$, respectively. In this study, the bacterial strains ISE13 and KJ1R5 could be potentially biocontrol agents to suppress Korean ginseng root rot caused by P. eaetorum. However, more attention using nutrient solution in hydroponic cultures for Korean ginseng production should be applied in biocontrol of plant diseases using the antagonistic microorganisms.

  • Objectives: Gallic acid (GA) is the major component of tannin which could be easily founded in various natural materials such as green tea, red tea, grape juice, and Corni Fructus. The purpose of this study is to investigate the effect of Gallic acid (GA) on production of interleukin (IL) in mouse macrophage Raw 264.7 cells stimulated by lipopolysaccharide (LPS). Methods: Productions of interleukins were measured by High-throughput Multiplex Bead based Assay with Bio-plex Suspension Array System based on $xMAP^{(R)}$ (multi-analyte profiling beads) technology. Firstly, cell culture supernatant was obtained after treatment with LPS and GA for 24 hour. Then, it was incubated with the antibody-conjugated beads for 30 minutes. And detection antibody was added and incubated for 30 minutes. And Strepavidin-conjugated Phycoerythrin (SAPE) was added. After incubation for 30 minutes, the level of SAPE fluorescence was analyzed on Bio-plex Suspension Array System and concentration of interleukin was determined. Results: The results of the experiment are as follows. 1. GA significantly inhibited the production of IL-3, IL-10, IL-12p40, and IL-17 in LPS-induced mouse macrophage RAW 264.7 cells at the concentration of 25, 50, 100, 200 uM (p<0.05). 2. GA significantly inhibited the production of IL-6 in LPS-induced mouse macrophage RAW 264.7 cells at the concentration of 50, 100, 200 uM (p<0.05). 3. GA diminished the production of some cytokine such as IL-4, IL-5, and IL-13 in LPS-induced mouse macrophage RAW 264.7 cells. 4. GA did not show the inhibitory effect on the production of IL-$1{\alpha}$ and IL-9 in LPS-induced mouse macrophage RAW 264.7 cells. Conclusions: These results suggest that GA has anti-inflammatory activity related with its inhibitory effects on the production of interleukins such as IL-3, IL-10, IL-12p40, IL-17, and IL-6 in LPS-induced macrophages.

  • In the present study, a suitable drying method was developed for citrus press cakes (CPCs), which are produced as a by-product in citrus juice plants, and the protective effect of methanol extract of CPCs prepared by far-infrared radiation (FIR) drying against $H_2O_2$-induced DNA damage was evaluated versus that of freeze-dried CPCs. Methanol extract of FIR-dried CPCs exhibited comparatively good ROS scavenging activity versus the freeze-dried CPCs at the concentration of 100 ${\mu}g$/mL. The extract strongly enhanced the cell viability against $H_2O_2$-induced oxidative damage in Vero cells. Lipid peroxidation inhibitory activity of the extract from FIR-dried CPCs was comparable to that of the extract from freeze-dried CPCs. This sample also exhibited good protective effects against $H_2O_2$-mediated cell apoptosis as demonstrated by decreased apoptotic body formation in the nuclear staining with Hoechst 33342. In the comet assay, the CPC extracts exhibited strong inhibitory effects against $H_2O_2$-mediated DNA damage in a dose-dependent manner. Thus, this study demonstrated that FIR drying effectively preserves CPC as a functionally important natural antioxidant source and the FIR drying can be adapted for drying CPCs and is more economical for massive production than freeze drying.

  • The purpose of this study was to estimate beverage consumption frequency and determine related problems of elementary school students in Chungnam. The survey was conducted with 488 students(boys=230, girls=258) using a questionnaire. The average age of the students was 10.1 years old, thir average height and weight were 145.1 cm and 39.5 kg, respectively and the obesity index was -1.3%. The frequencies for breakfast, lunch and dinner were 5.8 times/week, 6.7 times/week and 6.4 times/week, respectively. Regarding the frequency of snacks, high response rates for 'once/day'(38.3%) and 'none' (30.5%) were observed. Nutrition label on beverages were identified rarely(39.1%), nearly never(19.7%), and never(12.9%). The choice factors in selecting beverage were taste, nutrition, and price. For the type of snack most often consumed, fruit or juice was 25.8%, snack items were 25.2%, bread was 24.8%, dairy products were 7.6%, beverages were 7.0%, noddles were 6.2%, and rice cakes were 3.5%. The kinds of favorite beverages were carbonated drinks(30.3%), functional drinks (24.4%) and milk and yoghurt(23.8%), and main reason for the choice of beverage was "it tastes good". For the point of time that students wanted to drink a beverage, "when I feel thirsty" appeared most often for dairy products and beverages and the next most frequent answer was "after exercise". Therefore it may be necessary to administer systematic nutritional education on perception on nutrition fact label of beverage. And it is thought that plan for proper beverage consumption in elementary school students may be established.

  • This study purposed to restructure representative traditional patterns formatively, manufacture actual cultural products with traditional dyeing technique using persimmon, and commercialize the results of the research. Traditionally in Korea, the dying of natural fiber such as cotton, flax and silk with persimmon was called Galmul dyeing, and clothes made through Galmul dyeing were called Galot. Galot was very useful because it is strong, does not pick up dirt easily, dries easily, and is cool in summer. In addition, cloth dyed with persimmon becomes stiff, so it does not need to be starched or ironed after washing. Moreover, it does not transmit heat under direct rays and is highly air-permeable, so it is cool and useful for standing the heat. In this study, we used traditional persimmon dyeing technique, printing traditional patterns fit for contemporary people's aesthetic sense not through dip-dying but through printing. When persimmon dyeing is used in expressing patterns, it produces not only visual effect but also embossing effect due to the characteristic of persimmon that makes printed patterns stiff, so we can obtain unique texture distinguished from other printing methods. We chose seven motive patterns, which were lotus pattern symbolizing eternal life, peony pattern symbolizing wealth and rank and prosperity, character Su(壽) pattern widely used as a symbol of health, bird and cloud pattern in the Goryeo Dynasty, Sahapyeoeuisohwa(四合如意小花) pattern printed on brocade in the Goryeo Dynasty, lattice pattern, cloth pattern on wall paintings from the Period of the Three Kingdoms. From each pattern chosen as a motive was extracted unit patterns and the original pattern was restored using Adobe Illustrator. Restored patterns were restructured to be applied to cultural products fit for contemporary formative sense. Fabrics used in dyeing were cotton, linen, ramie, silk, and polyester. Although the same persimmon dyeing was applied, we produced different feelings of patterns using various fabrics and in some cases gold and silver powder was added for the effect of gloss in addition to the embossing of patterns. Using printed fabrics we manufactured tea pads, place mats, cushions, wrapping cloth for gifts, wallet, lampshades.

  • Many recent studies have focused on maintaining a healthy life by preventing and/or postponing the aging process. Numerous studies have reported that continuous exposure to reactive oxygen species can stimulate skin aging and that excessive accumulation of fat can cause an impaired skin barrier and tissue structure alterations. Thus, the maintenance of antioxidant homeostasis and the suppression of adipose accumulation are important strategies for skin anti-aging. Here, we prepared three types of extracts [whole juice, acetone-perchloric acid (PCA), and ethanol] from 20 fruits and medicinal herbs native to the Gyeongnam area of Korea. The total phenolic content of each extract was analyzed, and we observed higher total phenolic contents in the medicinal herbs. Consistent with this, the results of the oxygen radical absorbance activity capacity assay indicated that the in vitro antioxidant activities of the medicinal herb extracts were stronger than those of the fruit extracts. The fruits and medicinal herbs had strong effects on cell-based systems, including $H_2O_2$-induced oxidative stress in human keratinocytes and 3T3-L1 lipid accumulation. Nishimura Wase persimmon, Taishu persimmon, wrinkled giant hyssop, sweet wormwood, Chinese cedar, red perilla, tan shen, hiyodori-jogo, and cramp bark may be natural anti-aging materials with effective antioxidant and anti-adipogenic activities. Taken together, our findings may provide scientific evidence supporting the development of functional foods and nutraceuticals from fruits and medicinal herbs.
