  • The anti-inflammatory effects of ethanol extract from Grateloupia crispata (GCEE) were investigated in lipopolysaccharide (LPS)-stimulated murine macrophages. Anti-inflammatory effects were detected by enzyme-linked immunosorbent assay, Western blotting, and immunohistochemistry. There was no cytotoxic effect on proliferation of macrophages treated with GCEE compared to the control. GCEE significantly inhibited production of pro-inflammatory cytokines [interleukin (IL)-6, tumor necrosis $factor-{\alpha}$, and $IL-1{\beta}$] as well as nitric oxide in LPS-stimulated RAW 264.7 cells. In addition, GCEE suppressed expression of inducible nitric oxide synthase, cyclooxygenase-2, and nuclear $factor-{\kappa}B$ in a dose-dependent manner. GCEE significantly reduced activation of mitogen-activated protein kinases. In the in vivo test, evaluation of anti-inflammatory activity of GCEE was performed using croton oil-induced ear edema in ICR mice. Oral administration of 10 mg/kg to 250 mg/kg of GCEE significantly reduced ear edema in a dose-dependent manner compared to croton oil-induced mice. Moreover, GCEE reduced ear thickness and the number of mast cells compared to croton oil-induced mice in the histological analysis. These data suggest that GCEE could be used as a potential source for anti-inflammatory agents.

  • The critical need of forest road for enchanting the additional values of various forest products, in addition, giving more recreational opportunity to citizen, has been recognized. In this study the present author aimed to ascertain the most effective construction working plan of forest road being tit to Korean geographic condition. To execute this research program, four locations in national forest of Kangweon-do district and other four locations in private forest in Chollabuk-do district both where forest roads have previously been constructed were selected to analyze the effectiveness basing upon the various factors separately or in combination. The results are summarized as follows ; 1. The investment efficiency in forest road construction showed to increase in the area where terrain factors and district social factors rate is high, and to decrease in the area where forest status factors and forest road structure factors rate is high. So in future the Forest Resource Development Model of forest road should take more importance particularly on those area having terrain factor ratio is low. The extractable value of constructed forest road based on forest status factors rate is expected to increase in case of high considerably. 2. To construct of forest road for increasing multiple use of forests, forest road should be construct with priority on area where obtained total score by evaluation factors is high. And these evaluation factors should take possible determine the position of forest road construction. 3. The following five types of forest road basing upon function performance are suggested with regard to the place where road is constructed. (1) Forest Utilization Model ; where forest status factors and forest road structure factors rate are over 60%. (2) Forest Resource Development Model ; where terrain factors, forest status factors, forest road structure factors and district social factors rate are less than 60%. (3) Community Development Model ; where terrain factors, forest road structure factors and district social factors rate are over 60% but forest status factors rate are less than 60%. (4) Recreation and Health Model ; where terrain factors, forest status factors, forest road structure factors and district social factors rate are over 60%. (5) Multiple Use Model ; where both forest status factors and district social factors rate are over 60%.

  • This study was performed to investigate the effect of germinated Ilpum rough rice extract on blood glucose in C57BL/KsJ-db/db mice. The mice were divided into several groups: normal control (NC), diabetic control (DC), those fed with 0.25% germinated Ilpum rough rice extract (DM-0.25%GIRRE), those fed with 0.5% germinated Ilpum roughrice extract (DM-0.5%GIRRE) and those fed with 1% germinated Ilpum rough rice extract (DM-1%GIRRE). After 8 weeks of treatment, body weight, water intake, and diet intake of the DM-1%GIRRE group were significantly lower than the other DM groups. Blood glucose levels of the DM-1%GIRRE group were significantly lower compared to the DC group. Fasting blood glucose HbA1c level and total glucose tolerance test were significantly lower in the DM-1%GIRRE groups compared to the DC group. There was no significant difference in serum insulin level among each group. Therefore, the results of this study demonstrate that germinated Ilpum rough rice extract alleviates many of the symptoms of diabetes in genetically obese mice and may offer a possibility as a therapeutic supplement for the normalization of blood glucose levels in humans with hyperglycemia. It may also have beneficial effects in patients with non-insulin-dependent diabetes mellitus.

  • In this study, anti-arthritic effect of the mixed extract of radiation mutant Perilla frutescens var. crispa and Atractylodes macrophala koidz was investigated. Cell viability was determined by MTT assay in RAW 264.7 cells. The anti-inflammatory effect of mixed extracts was determined through measurement of the levels of reactive oxygen species (ROS) and nitric oxide (NO), release of inflammatory cytokines and expression of NF-κB, COX-2 and iNOS in LPS-induced RAW 264.7 cells after treatment of mixed extracts (5, 10, 25 ㎍/㎖). We showed that the mixed extracts was not toxic in the dose of 5, 10, 25 ug/ml, and significantly inhibited production of nitric oxide and ROS, cytokines including IL-1β, IL-6, TNF-α, and inflammatory proteins including NF-κB, COX-2 and iNOS in LPS-induced RAW 264.7 cells. Moreover, the mixed extract inhibited the type II collagen induced arthritis in DBA mice in the dose of 66.5 and 133mg/kg/day. Therefore, we suggest that mixed extract of radiation mutant Perilla frutescens var. crispa and Atractylodes macrophala koidz can be developed as a raw material for health functional food and therapeutics to treat the inflammatory arthritis.

  • According to the latest report by the Customer Protection Board, those who moved into newly constructed buildings are complaining about unidentified pains, asking for more careful selection of constructive materials for prevention of such potential problems. It is internationally recognized today that ecological materials can serve a significant factor for users' health, environmental protection and better industrial competitiveness. This study examined eco-design aspects of each interior material through web site search, in order to help customers learn about and capitalize on eco materials in a proper manner. As a result, 1. It turned out that the domestic industry are giving an impetus to releasing new eco items focusing on lower VOCs emission or addition of functional components as part of the marketing strategy. However, it is recommended that company understand significance of life cycle, and produce eco-concept materials. 2. The reliable standard for choosing the domestic material is EL, HB, GR marks. It is desirable to enhance recycling technologies and expand the sustainable consumption. customer class, since many recycled items are not developed. 3. The sourcing is a vulnerable part in terms of the concept of being environment-friendly material. Therefore, many manufacturers should design the easy knock-down products and produce the good items using recycled materials instead of new raw materials. Also solutions for making the energy from burning material should be studied. 4. The guidebook or manual with correct information about eco-materials is required to promote production and consumption with sustainable concept. 5. Many manufacturers are emphasizing ecological materials for customers, but some of them intended to disrupt customers' proper selection by promoting even unverified items to be environment-friendly.

  • This thesis study of the medical concept Qiu Zheng Lu (求正錄) is discussed in the Lei Jing Fu Yi (類經附翼), a book authored by Zhang Jie Bin (張介賓) a medical doctor during the Chinese Ming (明) dynasty (1368-1683). The meaning of Qiu Zheng Lu (求正錄) is "searching for the rightness." In his book Zhang Jie Bin (張介賓) intended to clarify Qiu Zheng Lu (求正錄) by delineating the concept into four categories. These are: Sanjiao Baoluo Mingmen Bian (三焦包絡命門 辨) the theory of the triple warmer, the Pericardium, the Gate of Life ; Da Bao Lun (大寶論) the theory of the great treasure of the human body; Zhen Yin Lun (眞陰論) the theory of true-yin fluid; and Shi Er Zang Mai Hou Bu Wei Lun (十二臟脈候部位論) the theory of the part of the pulse and its condition in regards to the twelve viscera. Sanjiao Baoluo Mingmen Bian (三焦包絡命門辨), the theory of the triple warmer, the Pericardium, the Gate of Life. The triple warmer (三焦: Sanjiao) is composed of three parts: the upper, middle, and lower. This concept is also connected with the functions and roles of the vital organs. The upper burner is related to the heart and lungs. The middle burner is related to the liver and spleen. Whereas, the lower burner is related to the kidneys. Bao-Luo (包絡) is the Pericardium, the envelope of the heart, serving as the protector of the heart. Ming-Men (命門) is the Gate of Life, reffering to the vitals of life. It functions as kidney-yang which is considered as the origin of yang-energy of the human body, and serves partly as the function of cortico-adrenal gland in modern medicine. Zhang Jie Bin (張介賓) discussed the Da Bao Lun (大寶論) as the most important function in the human body because the Da Bao (大寶/great treasure) is the true-yang (眞陽) which is the affective force for physiological functions, and as the source of energy for life activities. Moreover, true-yang (眞陽) functions both as a heater and thermometer that warms the human body and indicates vitality by levels of body warmth respectively. The Zhen Yin Lun (眞陰論) theory states that if true-yang (眞陽) is energy, then true-yin (眞陰) is the source of energy. This can be likened to a tree with roots which absorbs nutrients from the ground (source), and spreads the nutrients (energy) through its branches. Thus, true-yin (眞陰) is the root cause for later functional activities of true-yang (眞陽). In Shi Er Zang Mai Hou Bu Wei Lun (十二臟脈候部位論) the theory of the pulse (脈 /Mai) and its condition in regards to the twelve viscera, Zhang Jie Bin (張介賓) insisted that when a diagnoses by the pulse is made the five vital organs and the six viscera (五臟六腑) of a human body should be harmoniously arranged in accordance with its respective part of the pulse. Furthermore, Zhang Jie Bin (張介賓) supported his theory with evidence from earlier Chinese medical doctors. And, by stating that human beings must cultivate and preserve their true-yin (眞陰) and true-yang (眞陽) energies he therefore created four new prescriptions called: Zuoguiyin (左歸飮), Youguiyin (右歸飮), Zuoguiwan (左 歸丸), Youguiwan (右歸丸). To further clarify his theory Zhang Jie Bin (張介賓) considered that the function of true-yang (眞陽) and true-yin (眞陰) is expressed by Ming-Men (命門). This theory is that for humans to be spiritually and physically healthy they must live in accord with natural law. Also, within the framework of natural law, astronomical and geographical factors must be considered for complete, holistic, health. Thus, Ming-Men is the basis for healthy living in the modern world.

  • It has been recognized that the hen. like its mammalian counterparts. provides young chicks with antibodies as protection against hostile invaders. This system facilitates the transfer of specific antibodies from serum to egg yolk. and provides a supply of antibodies called immunoglobulin Y(IgY) to the developing embryo and the hatched chick. The protection against pathogens that the relatively immuno-incompetent newly hatched chick has. is through transmission of antibodies from the mother via the egg. Egg yolk. therefore. can be loaded with a large amount of IgY against pathogens which can immobilize the existing or invading pathogens during the embryo development or in day-old chicks. Thus. the immunization of laying hens to various pathogens results in production of different antigen-specific IgY in eggs. Egg yolk contains 8~20 mg of immunoglobulins (IgY) per $m\ell$ or 136~340 mg per yolk suggesting that more than 30 g of IgY can be obtained from one immunized hen in a year. By immunizing laying hens with antigens and collecting IgY from egg yolk. low cost antibodies at less than $10 per g compared to more than $20.000 per g of mammalian IgG can be obtained. This IgY technology opens new potential market applications in medicine. public health veterinary medicine and food safety. A broader use of IgY technology could be applied as biological or diagnostic tool. nut-raceutical or functional food development. oral-supplementation for prophylaxis. and as pathogen-specific antimicrobial agents for infectious disease control. This paper has emphasized that when IgY-loaded chicken eggs are produced and consumed. the specific antibody binds. immobilizes and consequently reduces or inhibits the growth or colony forming abilities of microbial pathogens. This concept could serve as an alternative agent to replace the use of antibiotics. since today. more and more antibiotics are less effective in the treatment of infections. due to the emergence of drug-resistant bacteria.

  • Secondary metabolism in actinomycetes has been known to be controlled by a small molecule, ${\gamma}$-butyrolactone autoregulator, the binding of which to each corresponding receptor leads to the regulation of the transcriptional expression of the secondary metabolites. We expected that expression of an autoregulator receptor or a pleiotropic regulator in a non-host was to be gained insight of effective production of new metabolic materials. In order to study the function of the receptor protein (seaR), which is isolated from Saccharopolyspora erythraea, we introduced the seaR gene to Streptomyces coelicolor A3(2) as host strains. An effective transformation procedure for S. coelicolor A3(2) was established based on transconjugation by Escherichia coli ET12567/pUZ8002 with a ${\varphi}C31$-derived integration vector, pSET152, which contained int, oriT, attP and $ermEp^*$ (erythromycin promotor). Therefore, the pEV615 was introduced into S. coelicolor A3(2) by conjugation and integrated at the attB locus in the chromosome of the recipients by the ${\varphi}C31$ integrase (int) function. Exconjugant of S. coelicolor A3(2) containing the seaR gene was confirmed by PCR and transcriptional expression of the seaR gene in the transformant was analyzed by RT-PCR. In case of S. coelicolor A3(2), a phenotype microarray was used to analyze the phenotype of transformant compared with wild type by seaR expression. After that, in order to confirm the accuracy of the results obtained from the phenotype microarray, an antimicrobial susceptibility test was carried out. This test indicated that sensitivity of the transformant was higher than wild type in tetracycline case. These results indicated that some biosynthesis genes or resistance genes for tetracycline biosynthesis in transformant might be repressed by seaR expression. Therefore, subsequent experiments, analysis of transcriptional pattern of genes for tetracycline production or resistance, are needed to confirm whether biosynthesis genes or resistance genes for tetracycline are repressed or not.

  • The purpose of this study was to investigate the biological benefits of apple peel. The antioxidant and anti-inflammatory activities of a 70% ethanol extract of apple peel were examined. The total phenolic compound and flavonoid contents of apple peel were $6.8{\pm}0.5mg$ gallic acid equivalent/g of fresh weight and $3.3{\pm}0.3mg$ catechin equivalent/g of fresh weight, respectively. Antioxidant activity was evaluated by measuring 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity. The DPPH radical scavenging activity of apple peel was $18.9{\pm}1.6$, $46.3{\pm}2.3$ and $58.1{\pm}3.9%$ at concentrations of 0.1, 0.5 and 1.0 mg/mL, respectively (p<0.05). The anti-inflammatory effect was investigated by measuring the inhibition of inflammatory enzymes. Apple peel significantly inhibited secretory phospholipase, cyclooxygenase-1, cyclooxygenase-2, and lipoxygenase activity by up to $53.5{\pm}2.3$, $13.4{\pm}1.8$, $64.8{\pm}5.4$ and $44.4{\pm}4.5%$, respectively (p<0.05). Taken together, these findings suggest that apple peel may act as an antioxidant by radical scavenging and may possess potential anti-inflammatory properties for suppressing the activity of inflammatory enzymes. These results also suggest that apple peel can be utilized as a health functional food ingredient possessing antioxidant and anti-inflammatory activities.
