Many traditional herbal remedies exhibit several beneficial effects including anti-inflammation. The exact mechanism of the a-inflammato action of Panax notoginseng Buck F.H. Chen. however, has not been determined. In the present study, we have isolted the acting compound, emodin, from P. notoginseng and examined the effects of p. notoginseng and emodin on lipopolysaccharide (LPS)-induced nitric oxide (NO) production, and inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) gene expression in RAW264.7 macrophages. The results indicated that p. notoginseng concentration-dependently inhibited LPS-induced NO production. Furthermore, P. notoginseng inhibited the expression of LPS-induced iNOS and COX-2 proteins without an appreciable cytotoxic effect on RAW264.7 cells. Emodin also inhibited LPS-induced iNOS protein as potently as P. notoginseng. This was consistent with the findings that P. notoginseng but not emodin inhibited prostaglandin E2 synthesis induced Dy LPS.

Handayeolso-Tang(HDT) has been used as traditional medicine for the treatment of Taeumin TaeYang-Hanguel. The present study was conducted to investigate the anti-allergic activity of Handayeolso-Tang(HDT). We investigated the anti-allergic effects of HDT in RBL-2H3 basophilic leukemia cells by compound48/80, a mast cell degranulator and compound 48/80 induced anaphylactic shock in mice. HDT significantly inhibited ${\beta}-hexosaminidase$ and histamine release from compound 48/80 stimulated RBL-2H3 cells. In addition, HDT effectively inhibited anaphylactic shock in mice by 45% at a dose 120 mg/mouse versus PBS treated control after the I.p injection(8 mg/kg) of compound 48/80. The in vitro anti-inflammatory activities of HDT in LPS-stimulated RAW 264.7 cells were investigated. HDT inhibited NO production in LPS-stimulated RAW 264.7 cells and effectively dowregulated the expression of iNOS mRNA and iNOS protein expression in LPS -stimulated RAW 264.7 cells. These result provide evidences that HDT may be beneficial in the treatment of allergic inflammtory disease.

We evaluated the potential protective activity of the traditional Korean medicinal herb, Corni fructus (CF), in an experimental model of hepatotoxicity induced by carbontetrachloride $(CCl_4)$. The CF exhibited a hepatoprotective activity against Chang cell. And The expression of cytochrome P450 2E1 (CYP2E1), measured by RT-PCR and western blot, was significantly decreased in the CF treated Chang cell. But $CCl_4$ and CF has no significant effect on 1A1 and 3A1 isoform of cytochrome P450. Based on these findings, it is suggested that hepatoprotective effects of CF possibly related to antioxidative effects and downregulation of CYP2E1 expression.

Celandine (Chelidonium majus, family Papaveraceae) is an herb used extensively in traditional Korean medicine. To investigate its antioxidant and antiproliferative activities, the methanolic extract of celandine was introduced. The antioxidant properties of the extract were tested using various in vitro systems, including hydroxyl radical scavenging assay, DNA damage protection assay, 1,1-diphenyll-2-2-pricylhydrazyl (DPPH) free radical scavenging activity, metal chelating activity, and reducing power assay. The extract exhibited stronger antioxidant activity ($IC_{50}=7.92{\mu}g/mL$) against hydroxyl radicals in the Fenton system than butylated hydroxyanisole ($IC_{50}=51.46{\mu}g/mL$) and $\alpha$-tocopherol ($IC_{50}=67.48{\mu}g/mL$). Likewise, damage to the plasmid pBR 322 induced by hydroxyl radicals was found to be protected by the extract at a concentration of $400{\mu}g/mL$. Cellular proliferation and the induction of apoptosis were also examined by a cellular proliferation assay, flow cytometry, and mRNA expression analysis. Taken together, the extract significantly inhibited the growth of HT-29 cells in a concentration- and time-dependent manner, and gradually increased both the proportion of apoptotic cells and the expression of caspase-3. Overall, our research suggests that celandine possesses antioxidant and antiproliferative properties.

PURPOSE : Andrographis Herba is used as a traditional herbal medicine in the Asian countries for the treatment common cold, fever, diabetes, hypertension, hepatitis, skin infections, snake bite, and other diseases. In this study, we investigated the anti-inflammatory effect of MeOH extract of Andrographis Herba (AHME) on LPS-activated Raw 264.7 cells. METHODS : Cell viability was determined by MTT assay. Nitric oxide (NO) production was determined by Griess reagent. Pro-inflammatory cytokines were detected by enzyme-linked immunosorbent assay. Expression levels of pro-inflammatory proteins were determined by Western blot analysis. RESULTS : Production of NO in LPS activated Raw 264.7 cells, was significantly decreased by pre-treatment with 3-30 ㎍/mL of AHME. Production of pro-inflammatory mediators such as TNF-α and IL were significantly decreased by AHME 30 ㎍/mL pre-treatment. AHME significantly decreased p-IκB and NF-κB expression. CONCLUSION : The results of this study indicate that AHME could inhibit the acute inflammatory response, via modulation of NF-κB activation.

Objectives : Korean traditional medicinal herbs have been used to improve the function of the hematopoietic system. The purpose of this study is to examine the hematopoietic effects of Juakium-derivative on aplastic anemia. Methods : In vitro, after bone marrow cells of mice with aplastic anemia induced by benzene were cultured with Juakium-derivative, we measured the gene expressions of hematopoietic cytokines, the intracellular TPO and SCF expression and the colony number of CFU-GEMM and BFU-E. Results : The results are summarized as follows : 1. The gene expressions of hematopoietic cytokines (TPO, c-mpl, SCF, c-kit, IL-3, EPO, EpoR, GM-CSF) and the TPO and SCF expression of the group treated with Juakium-derivative increased significantly more than those of the control group. 2. The colony number of CFU-GEMM and BFU-E in the rEPO plus rIL-3 plus Juakium-derivative group increased significantly compared with the only rEPO plus rIL-3 group. Conclusion : It was acknowledged that Juakium-derivative has hemato-potentiating effects on aplastic anemia induced by benzene and it is expected that Juakium-derivative can be used clinically for the patient with hematopoietic system disorder. This study could also be used further as important research data for Korean oriental medicine about hemato-potentiating. The exact mechanism explaining our study would need to be studied further.

Wild ginseng has been used as a traditional medicine for thousands of years and for increase physical strength in Korea, China and Japan. This study reports that cultivated wild ginseng (CWG) inhibits adipocyte differentiation of 3T3-L1 pre-adipocytes in a concentration-dependent manner. Inhibition of adipocyte differentiation is one possible anti-obesity strategy. CWG inhibits the expression of the adipocyte differentiation regulator peroxisome proliferators-activated receptor (PPAR)${\gamma}$ and CCAAT/enhancer-binding protein ${\alpha}$mRNA. It also inhibited the expression of PPAR${\gamma}$ and adiponectin at the protein level during the differentiation of pre-adipocytes into adipocytes. Additionally, CWG blocked the cell cycle at the sub-$G_1$ phase transition, causing cells to remain in the pre-adipocyte state. These results indicate that CWG inhibits adipocyte differentiation and adipogenesis through pre-adipocyte cell cycle arrest in cultured 3T3-L1 cells.

Ginseng (Panax ginseng C.A. Meyer), one of the most widely used medicinal plants in traditional oriental medicine, is used for the treatment of various diseases. It has been classified according to its cultivation environment, such as field cultivated ginseng (FCG) and mountain cultivated ginseng (MCG). However, little is known about differences in gene expression in ginseng roots between field cultivated and mountain cultivated ginseng. In order to investigate the whole transcriptome landscape of ginseng, we employed High-Throughput sequencing technologies using the Illumina HiSeqTM2500 system, and generated a large amount of sequenced transcriptome from ginseng roots. Approximately 77 million and 87 million high-quality reads were produced in the FCG and MCG roots transcriptome analyses, respectively, and we obtained 256,032 assembled unigenes with an average length of 1,171 bp by de novo assembly methods. Functional annotations of the unigenes were performed using sequence similarity comparisons against the following databases: the non-redundant nucleotide database, the InterPro domains database, the Gene Ontology Consortium database, and the Kyoto Encyclopedia of Genes and Genomes pathway database. A total of 4,207 unigenes were assigned to specific metabolic pathways, and all of the known enzymes involved in starch and sucrose metabolism pathways were also identified in the KEGG library. This study indicated that alpha-glucan phosphorylase 1, putative pectinesterase/pectinesterase inhibitor 17, beta-amylase, and alpha-glucan phosphorylase isozyme H might be important factors involved in starch and sucrose metabolism between FCG and MCG in different environments.

Atherosclerosis, which manifests as acute coronary syndrome, stroke, and peripheral arterial diseases, is a chronic inflammatory disease of the arterial wall. Prunella vulgaris, a perennial herb with a worldwide distribution, has been used as a traditional medicine in inflammatory disease. Here, we investigated the effects of P. vulgaris ethanol extract on TNF-${\alpha}$-induced inflammatory responses in human aortic smooth muscle cells (HASMCs). We found that P. vulgaris ethanol extract inhibited adhesion of monocyte/macrophage-like THP-1 cells to activated HASMCs. It also decreased expression of intercellular adhesion molecule-1, vascular cell adhesion molecule-1, E-selectin and ROS, No production in TNF-${\alpha}$-induced HASMCs and reduced NF-${\kappa}B$ activation. Furthermore, P. vulgaris extract suppressed TNF-${\alpha}$-induced phosphorylation of p38 mitogen-activated protein kinase (MAPK) and extracellular signal-regulated kinase (ERK). These results demonstrate that P. vulgaris possesses anti-inflammatory properties and can regulate TNF-${\alpha}$-induced expression of adhesion molecules by inhibiting the p38 MAPK/ERK signaling pathway.

Dries Van Noten, one of the Antwerp Six, focused on recreating traditional attire from each region to complex contemporary attire and has shown designs that interpreted ethnic image in contemporary perspective from his very first collection. He has positioned himself as a designer with creative expression of ethnic image through broad use of various patterns. This paper analyze the use of pattern in Dries Van Noten's designs by season and item, and reflects on the characteristics of pattern use and influence on fashion image. Total of 887 clothing items were collected from Noten's collections on the Internet. Through analysis of frequency and percentage and cross tab of expression techniques, types, patterns of each motif, and classifications of print combinations, it was shown that Noten has applied six aesthetic rules in the use of pattern design. Pattern played the most significant role in his design. It was possible to achieve the balance of ethnic image and modern image with the mix of flower and abstract motives. Overall pattern was mostly used for practical purpose: border patterns and spaced patterns played a vital role in rendering uniqueness. Noten exhibited unity and variation in combining prints. He expressed the beauty of Oriental style by inserting solid color blocks in between patterns and decorations along trim lines.
