  • The fruits of Eleutherococcus sessiliflorus (Rupr. & Maxim.) S. Y. Hu (Araliaceae), as edible fruits, were traditionally used for ingredients of wine or tea in Eastern Asia. In addition to, the fruits of E. sessiliflorus were known for having antioxidant and anti-inflammatory effects. Recently, we investigated that the ethanolic extracts of E. sessiliflorus fruits (DHP1501) have effects on hypertension via vasorelaxation and decrease of blood pressure. In the present study, we investigated that the gene and protein expression levels of endothelial nitric oxide synthase (eNOS) was increased by treatment of DHP1501 in HUVECs. Moreover, we confirmed the angiotensin converting enzyme inhibitory activity of DHP1501 through in vitro tasks. Therefore, DHP1501 could be a candidate of functional food for alleviating hypertension.

  • The study was conducted to investigate the possibility that epigenetic DNA methylation causes tree phenotypic variation in autotetraploids through evaluating the phenotypic variation and DNA methylation in autotetraploids occurred spontaneously from diploid trifoliate orange. Chromosome analysis confirmed that fourteen trifoliate orange trees of selected by flow cytometry were tetraploids (2n = 4X = 36) without any aneuploids. Chromomycin A3 staining determined that these trees were all autotetraploid with doubled chromosome set. Tree phenotypes, such as tree height and width, branching number, length, and angle, internode length, and leaf characteristics, varied in the autotetraploids. Chlorophyll indices were diverse in the autotetraploids, but photosynthetic rates were not significantly different. In addition, a wide range of variation was observed in stomatal density and guard cell length. Analysis of global cytosine DNA methylation showed that there was a variation of the methylation level in autotetraploids. More than half of 14 autotetraploids had at least 2 times higher methylation level than diploid trifoliate orange. The results indicate that tree phenotypic variation in autotetraploids might be related to global DNA methylation for reducing gene redundancy.

  • This study was conducted to compare and analyze the qualitative property of MLT (mulberry leaf tea) and FMLT (fermented mulberry leaf tea) based on the antioxidant, anticancer activities of various extracts. When the antioxidant activity of MLT and FMLT extracts was evaluated, the electron donating activity was found to increase proportionally as the concentration of each extract increased. In addition, the extract of FMLT showed a higher electron donating activity than that of MLT. Furthermore, the ethanol extracts showed the highest electron donating ability. When the SOD activity was evaluated, it was also found to increase proportionally with the concentration of each extract. Furthermore, the SOD activity of the ethanol extract group was the highest, whereas the SOD like activities of both MLT and FMLT were similar. When nitrite decomposition was evaluated for each pH, the highest value was observed at pH 1.2. Finally, the nitrite deleting ability was the highest for the ethanol extracts. When each extract of MLT and FMLT was analyzed in vitro for anticancer effects, they were found to decrease the number of cancer cells proportionally as the concentration of extract increased for both HeLa cells and MCF-7 cells. Furthermore, FMLT was found to exert a greater inhibition of cancer cells than MLT. Among the extract groups, the ethanol extract induced the greatest inhibition of the development of cancer cells, and these effects were greater against MCF-7 cells than HeLa cells.

  • We studied the physical, chemical, biological, and antimicrobial effects of eight types of essential oils used in the cosmetics industry: lavender, tea tree, rosemary, juniper berry, Chamaecyparis obtusa, cypress, cedar wood, and pine. Lavender oil had a linalyl acetate (an ester chemical compound) content of 48% and radical scavenging activity of 22.36% at 5,000 ppm. Tea tree oil had radical scavenging activity of 43.94% at 5,000 ppm and antimicrobial activity against S. aureus, S. epidermidis, S. mutans, and C. albicans in each 6, 3.5, 6.5, and 5 mm, respectively. Chamaecyparis obtusa oil had the highest acidity (pH 2.64) compared with the other oils, and sesquiterpene compounds were found to have 19.20%. Cedar wood oil had the highest specific gravity and refractive index compared to the other oils and had a sesquiterpene content of 99.73%. The radical scavenging activity of cedar wood essential oil exceeded 39.68% at 5,000 ppm. The clear zone, indicating antimicrobial activity against P. acnes, P. ovale, and C. albicans, was 3.5, 6, and 6 mm, respectively, at a concentration of 1% cedar wood oil. Results showed that with a high sesquiterpene content, the antioxidant effect was generally, but not always, high, suggesting that this is determined according to composition of the compound rather than presence of each antioxidant. The results indicate that antimicrobial activity is determined by the existence of each antimicrobial ingredient rather than terpene composition.

  • This experiment was conducted to determine optimal hot-air drying time for producing antioxidative calendula tea. The edible calendula was dried in hot air at $60^{\circ}C$ for 5, 10, 15 hours and Hunter's color value was measured and extracted with 95% ethanol as a solvent. The contents of total polyphenol, total flavonoid, total carotenoid and DPPH (2,2 Dipheny-1-picrylhydrazyl) radical scavenging activity were investigated. The correlation between the amount of antioxidant and antioxidant activity was analyzed. As the treatment time increased, the Hunter values of L, a, and b tended to decrease, and the L value and b value decreased significantly at 15 hours. The color change was occurred in all treatments compared with the control, and the total color difference (${\Delta}E$) was the largest at 15 hours treatment. The contents of total flavonoids, total carotenoids and DPPH scavenging activity increased in the 5 hours, but decreased in the 15 hours compared to the 10 hours. The content of total polyphenol was not changed with different treatment time. A positive correlation ($p{\leq}0.01$, r = 0.610) between carotenoids and DPPH radical scavenging activity was demonstrated. The DPPH radical scavenging activity was increased at 5 and 10 hours compared to the control and decreased at 15 hours. Therefore, 5 hours or 10 hours of treatment is appropriate and further studies are needed to determine the specific treatment time.

  • Objectives : The purposes of this study were to investigate the recognition of Mibyeong, symptom, management plan and correlation between quality of life and health condition, and to suggest a plan for managing Mibyeong status. Methods : Participants were recruited based on the same sampling methods used on the previous study performed in 2013 based on area, gender and age. Questionnaires were collected by Gallup Korea professional surveyor through face-to-face interviews. The questionnaires contain questions about the recognition of Mibyeong, symptom, management plan and the quality of life in accordance with the relevant health conditions. Descriptive statistics were used for data analysis and the results were expressed as percentage ratios (%). Results : 1,100 of people were acquired in 2015. The responses for "First time to hear of Mibyeong" have shown that the percentage were reduced from 80% to 67% compared with 2013 data. The ratio of Mibyeong's symptoms in 2015 were similar to 2013. we suggested some ways to deal with the Mibyeong status including behavior adjustment (non smoking, non alcohol, control sleep pattern), herbal tea, health functional food, exercise, preventive health care (qi-gong, yoga), meditation, home health care medical device (hot-pack, seat device for fumigation, massager), and medical service (hospital, medical clinic oriental medical clinic). Almost people showed that positive opinion with them. There were significant correlation between quality of life with the health status rather than Mibyeong or disease group. Conclusions : This study was performed through scientific questionnaires collected in 2013 and 2015 to investigate people's understanding of Mibyeong as a present condition in Korean public. Some questions had significantly different responds between both years while others showed similar trends for both years. These results suggest that the concept of Mibyeong in oriental medicine could provide a management mechanisms that help people to manage the Mibyeong status.
