  • objective : The purpose of this research is to examine the effects of Scutellaria Radix(SR) extract on immune cells and cytokines in ovalbumin(OVA)-induced asthmatic mice. Methods : In vivo, C57BL/6 mice were sensitized and handicapped by OVA for 9 weeks. In this experiment, one group was not treated, and the other group was treated with SR extract for six weeks(five times per week) and analyzed by ELISA and flow cytometer. Results : In vivo, there were significant decreases in eosinophils, IL-4, IL-13 in BALF (bronchoalveolar lavage fluid) compared with that of control group. However,$IFN{\gamma}$ in the SR group increased significantly compared with that of control group. Additionally, the population of $CD3e^-/CCR3^+,\;CD69^+/CD3e^+,\;IgE^+/B220^+,\;CD11b^+/Gr-1^+$ cells in the SR group decreased compared with that of control group. conclusion : The results of this study support a role for SR as an effective treatment for asthma in its experimental success in significantly decreasing inflammation and asthma reactions, and in increasing $IFN{\gamma}$, Which helps prevent such reactions.

  • Objectives : The aim of this study is to develop the system and evaluate the optical analytical technique that reflects acupoint pigmentation and extravasated blood by cupping. Methods : We designed the system able to express XYZ coordinate on local skin color. To evaluate measurement-accuracy, we compared with 24 Color Checker Chart by standardized Commission Internationale de l'Eclairage. After confirming the performance of system, we experimented with cupping which was 80 kPa negative pressure for 1 minute on left/right BL13. The X, Y and Z values were converted to R, G and B, $L^*$, $a^*$ and $b^*$, Erythema Index (E.I.), and Melanin Index (M.I). We compared and analyzed two cases on before/after cupping. Results : The R, G and B values which were converted by X, Y and Z values had high linearity as a high level of R-square (R: 0.969, G: 0.996, and B: 0.992). Moreover, we confirmed that it was possible to quantitatively analyzed the change in skin color by cupping using R, G, B, $L^*$, $a^*$, $b^*$, E.I., and M.I. Conclusions : Therefore, we proposed the new analytical technique for objectifying the oriental medical diagnostic method using cupping and optical sensing technique.

  • β-Glucosidases and β-xylosidases are two categories of enzymes that could cleave out non-reducing, terminal β-D-glucosyl and β-D-xylosyl residues with release of D-glucose and D-xylose, respectively. In this paper, two functional β-glucosidase Dth3 and β-xylosidase Xln-DT from Dictyoglomus thermophilum were heterologously expressed in E.coli BL21 (DE3). Dth3 and Xln-DT were relatively stable at 75℃ and were tolerant or even stimulated by glucose and xylose. Dth3 was highly tolerant to glucose with a Ki value of approximately 3 M. Meanwhile, it was not affected by xylose in high concentration. The activity of Xln-DT was stimulated 2.13-fold by 1 M glucose and 1.29-fold by 0.3 M xylose, respectively. Furthermore, the βglucosidase Dth3 and β-xylosidase Xln-DT showed excellent selectivity to cleave the outer C-6 and C-3 sugar moieties of ASI, which established an effective and green method to produce the more pharmacologically active CAG, an exclusive telomerase activator. We measured temperature, pH and dosage of enzyme using a single-factor experiment in ASI biotransformation. After optimization, the optimal reaction conditions were as follows: 75℃, pH 5.5, 1 U of Dth3 and 0.2 U of Xln-DT, respectively. Under the optimized conditions, 1 g/l ASI was transformed into 0.63 g/l CAG with a corresponding molar conversion of 94.5% within 3 h. This is the first report to use the purified thermostable and sugar-tolerant enzymes from Dictyoglomus thermophilum to hydrolyze ASI synergistically, which provides a specific, environment-friendly and cost-effective way to produce CAG.

  • BACKGROUND/OBJECTIVES: Previous studies have indicated that when compared to young mice, old mice have lower global DNA methylation and higher p16 promoter methylation in colonic mucosa, which is a common finding in colon cancer. It is also known that a Western-style diet (WSD) high in fat and calories, and low in calcium, vitamin D, fiber, methionine and choline (based on the AIN 76A diet) is tumorigenic in colons of mice. Because DNA methylation is modifiable by diet, we investigate whether a WSD disrupts DNA methylation patterns, creating a tumorigenic environment. SUBJECTVIES/METHODS: We investigated the effects of a WSD and aging on global and p16 promoter DNA methylation in the colon. Two month old male C57BL/6 mice were fed either a WSD or a control diet (AIN76A) for 6, 12 or 17 months. Global DNA methylation, p16 promoter methylation and p16 expression were determined by LC/MS, methyl-specific PCR and real time RT-PCR, respectively. RESULTS: The WSD group demonstrated significantly decreased global DNA methylation compared with the control at 17 months (4.05 vs 4.31%, P = 0.019). While both diets did not change global DNA methylation over time, mice fed the WSD had lower global methylation relative to controls when comparing all animals (4.13 vs 4.30%, P = 0.0005). There was an increase in p16 promoter methylation from 6 to 17 months in both diet groups (P < 0.05) but no differences were observed between diet groups. Expression of p16 increased with age in both control and WSD groups. CONCLUSIONS: In this model a WSD reduces global DNA methylation, whereas aging itself has no affect. Although the epigenetic effect of aging was not strong enough to alter global DNA methylation, changes in promoter-specific methylation and gene expression occurred with aging regardless of diet, demonstrating the complexity of epigenetic patterns.

  • Objectives : Atopic dermatitis is a chronic inflammatory skin disease characterized by pruritic and erythematous skin lesions. The purpose of this study was to investigate the suppressive effects of Lonicerae Flos, Forsythiae Fluctus and Hwangryunhaedok Decoction Pharmacopuncture on the development of atopic dermatitis-like skin lesions in NC/Nga Mice. Methods : The Atopic Dermatitis was induced by biostir AD on the mice's back skin. Experimental groups were divided into three including LFP(Lonicerae Flos Pharmacopuncture, EtOH extract), FFP(Forsythiae Fluctus Pharmacopuncture, EtOH extract) and HHP(Hwangryunhaedok Decoction Pharmacopuncture, Hydrodistillation extract). Every second day, the mice of three groups were treated with $0.1m{\ell}$ of pharmacopuncture using a syringe at right and left acupoints ($BL_{13}$), alternatively. On the control group, normal saline was used instead of pharmacopuncture. Subsequently optical observation with a handscope, a clinical skin score, Tissue(general/immune) mast cell, Serum IgE level, Serum histamine level, and Serum lymphokine(IL-2, IL-4, $IFN-{\gamma}{\gamma}$) were measured. Results : FFP and HHP decreased the clinical skin score, the total cell number of mast cells, and the Serum total IgE level and Serum histamine level. In Serum lymphokine levels, all groups were decreased to the IL-4 level, LFP and FFP were increased to the IL-2 level, and LFP was increased to the $IFN-{\gamma}$ level. Conclusions : From the above results, Forsythiae Fluctus Pharmacopuncture (EtOH extract) and Hwangryunhaedok Decoction Pharmacopuncture (Hydrodistillation extract) exerted anti-allergic and anti-inflammatory effects, suggesting a promising agent for improving atopic dermatitis related symptoms.

  • Objective : KagamJwagwiEum(KJE) has been used for the purpose of prevention and treatment of bronchial asthma and allergic asthma in Korea. To investigate the biological effect of KJE, the author examined cytotoxicity and inflammatory cytokines secretion with human leukemic mast cell line, HMC-1. Methods: HMC-1 was stimulated with phorbol 12-myristate 13-acetate(PMA) and calcium ionophore A23187. KJE by itself had no effect on viability of HMC-l. The effects of KJE on the secretion of tumor necrosis $factor-alpha(TNF-{\alpha})$, interleukin(IL)-6 and IL-8 from HMC-1 were evaluated with enzyme-linked immunosorbent assay. Results : KJE inhibited PMA plus A23187-induced $TNF-{\alpha}$ and IL-6 secretion. But KJE had no effect IL-8 secretion: KJE had immunoregulatory effects on cytokines, increased secretion of NO and $TNF-{\alpha}$ but did not effect IL-12 secretion when the cells were primed and trigged with $IFN-{\gamma}$ in the peritoneal macrophages of C57BL/6 mice. Conclusions : Taken together, these results suggest that KJE inhibit the production of inflammatory cytokines in HMC-1 cells and activate macrophages.

  • In order to determine the role of Peyer's patch lymphocytes (PPL) in self-clearing of Cryptosporidium parvum infection in murine models, changes in PPL subsets, their cytokine expression, and in vitro IgG1 and IgA secretions by PPL were observed in primary- and challenge-infected C57BL/6 mice. In primary-infected mice, the percentages of CD4+ T cells, CD8+ T cells, slgA+ B cells, IL-2+ T cells, and $IFN-{\gamma}+$ T cells among the PPL, increased significantly (P < 0.05) on day 10 post-infection (PI). Secretion of IgG1 and IgA in vitro by PPL also increased on day 10 PI. However, all these responses, with the exception of IgG1 and IgA secretions, decreased in challenge-infected mice on day 7 post-challenge (= day 13 PI); their IgG1 and IgA levels were higher (P > 0.05) than those in primary-infected mice. The results suggest that murine PPL play an important role in self-clearing of primary C. parvum infections through proliferation of CD4+, CD8+, IL-2+, and $IFN-{\gamma}+$ T cells, and IgG1 and IgA-secreting 8 cells. In challenge infections, the role of T cells is reduced whereas that of 8 cells secreting IgA appeared to be continuously important.

  • The purpose of this study is to collect and analyze costumes presented in international dance sports competitions, and summarize the features of Latin American dance costumes' design. As for research methods, standards of Latin American dance costume design were analyzed via a literature review on dance sports. The scope of the study extended for six years from 2010 to 2015 to include the, top three UK Latin American dance competitions. The results are as follows. First, the silhouette analysis determined that the X silhouette to the lead with, -145 costumes (78%), followed by the H silhouette at 25 (13%), and other at 16 (9%). Amongst those there were 174 one-piece dresses (94%). Furthermore, the analysis on colors of Latin American dance sports costumes revealed that, amongst the 186 costumes, 115 were without color (62%), Bl(black) is the most frequent with 37%, then Wh(white) with 21% and Gr(gray) with 4%. Costumes with colors, based on the six basic colors in the Munsell color system, are comprised most often of red with 12%, the followed by Y(yellow) at 10%, B(blue) at 8%, YR(yellow-red) at 4%, P(purple) at 2%, and G(green) at 2%. Thirdly, the cloth materials of Latin American dance costumes are recognized through image inspection. Among visually recognizable materials, beading materials are the most common with 104 costumes (60%). Shiny materials like mesh, chiffon, organza, lace and burn-out are in 36 costumes in total (19%). Other cloth materials included Luster materials and; non-sheen materials, which were in 46 costumes (25%).

  • Obesity is a physical condition that results from excessive storage of fat in the body. The present study examined the anti-obesity effects of the selected natural medicine, Galla rhois extract (GRE) and solvent fractions on 3T3-L1 preadipocytes and in vivo studies. Here, we show that EtOAc fraction of Galla rhois inhibits the differentiation of the 3T3-L1 preadipocytes induced by differentiated medium in a dose-dependent manner. To investigate the effect of the GRE-EtOAc fraction on obesity in high fat diet-fed C57BL/6 mice, which included a normal diet (ND), high-fat diet (HFD) and HFD+GRE concentration-dependent, were fed to the mice for 6 weeks. The GRE-EtOAc fraction was inhibited the highest adipocyte differentiation in vitro, the GRE supplement significantly decreased body weight and visceral fat mass compared to the HFD group. The total cholesterol and triglyceride levels in the plasma were significantly decreased by GRE supplementation compared with those of the HFD group. Also, we aimed to determine the differentiation inhibition and the modulation of differentiation genes brought about by the Galla rhois in adipocyte. A cDNA microarray-based method was introduced for the high contents screening (HCS) of gene expressions. This technology has revolutionized gene expression studies by providing the means to measure mRNA levels in thousands of genes simultaneously in simple and complex biological samples. 13 genes were founded to be affected in their expression levels by more than 5-fold up-regulation after 4 days treatment with the EtOAc fraction from Galla rhois. Otherwise, 21 genes were founded to be affected in their expression levels by more than 5-fold down-regulation treated with the EtOAc fraction. Therefore, Galla rhois extract may be considered for use in a therapeutic agent to control obesity.
