Objectives : The purpose of this study is to prove the effect and mechanism of Gamikyejakjimogawusul-tang(GKHA) herbal acupuncture on induced rheumatoid arthritis model of DBA/1 mice. Methods : We check effect of GKHA extract on the AST, ALT, Creatinine, BUN of serum and cell viability of GK extract in RAW 264.7 cells to test the stability of this study. In vitro, we measure total phenol contents, total flavonoid contents, DPPH free radical scavenging activity, ABTS cation radical scavenging activity of Gamikyejakjimogawusul-tang, effect of GK extract on ROS(Reactive Ooxygen Species) production to estimate a anti-oxidant capacity, and we also measure effect of GK extract on NO (Nitric Oxid), IL-$1{\beta}$, IL-6, IL-17, IL-21, TNF-${\alpha}$, MCP-1, GM-CSF production in RAW 264.7 cells to estimate a anti-inflammatory efficacy. In vivo, we compare a rheumatoid arthritis manifestation between control and experimental group and estimate a AI. Then we check effect of GKHA on the level of WBC, neutrophil, lympocyte, monocyte in the blood to see the effect of immune cells in blood. In addition we measure effect of GKHA on the level of hs-CRP, IgM, IgG, IL-$1{\beta}$, IL-6, IL-17, IL-21, TNF-${\alpha}$, MCP-1, GM-CSF in serum. We observe effects of GKHA on imaging of cartilage degeneration using micro CT-arthrography in paw hind. And we calculate effects of GKHA that reduced BV ratio, BS/BV ratio using 3D Micro-CT. Lastly we observe effects of GKHA histopathologic examination analysis. Results : 1. The toxicity on liver and kidney was disregardable and the cytotoxicity against RAW 264.7 cells was also disregardable. 1. Total phenol contents and total flavonoid contents in GK extract were in high level. 2. DPPH free radical scavenging activity and ABTS cation radical scavenging activity were increased according to concentration of GK extract 3. ROS production was significantly decreased in GK extract (at 10, $100{\mu}g/ml$). 4. NO, IL-6, TNF-${\alpha}$, MCP-1 production were significantly decreased in GK extract(at 10, $100{\mu}g/ml$). IL-17, GM-CSF production were significantly decreased in GK extract(at 1, 10, $100{\mu}g/ml$). IL-$1{\beta}$, IL-21 production were also decreased but there was no statistical significance. 5. 25x observation after H&E and M-T staining, infiltration of immune cells and subsidence of the cartilage and damage to the synovial cells were decreased. Conclusions : This study showed that GKHA extract had anti-oxidant capacity, anti-inflammatory efficacy. GKHA extract also had inhibiting effect on the process of rheumatoid arthritis and can protect joint and cartilage. So we expect that GKHA extract can be a meaningful treatment to rheumatoid arthritis patients.

Eosinohil and IgE responses of interleukin IL(-5 transgenic and normal C3H/HeN mice were studied after experimental infection with Nippostrongylus brasiliensis 9Nb). Intestinal worms were recovered at day 5 post-infection (PI), and numbers of total white blood cells (WBC) and eosinophils, and total serum IgE and anti-hapten (dinitrophenyl)(DNP) specific IgE titers, were measured at days 0,14 and PI. IL-5 mice appeared resistant to Nb infection showing a significantly ower worm recovery rate than normal mice (P<0.05). Total WBC and eosinophil counts (/mm3) were significantly increased in Nb infected normal mice (p<0.05), but unchanged (total WBC) or decreased (eosinophils) in IL-5 mice at day 21 PI. The total serum IgE level remarkably increased in normal mice, but only a little in IL-5 mice at days 14 and 21 PI. Priming with DNP brought about more remarkable increases of the total and anti-DNP specific IgE in normal mice than in IL-5 mice. The results show that IL-5 mice are resistant to Nb infection, and that eosinophil and IgE responses in these mice are not augmented by N infection.

Atopic dermatitis is a recurrent or chronic eczematous skin disease with severe pruritus and has annually increased in Korea. In this study, we investigated whether Duchesnea chrysantha (Dc) extracts have an anti-inflammatory effect in human monocytic THP-1 cells and human eosinophilic EoL-1 cells. The dried and powdered whole plants of Dc were extracted with 80% EtOH (Dc-1). The residue was diluted with water, and then successively partitioned with n-hexane, EtOAc, and BuOH to produce the n-hexane (Dc-2), EtOAc (Dc-3), BuOH (Dc-4), and the water-soluble fractions (Dc-5), respectively. The mite extract and LPS increased the production of IL-6, IL-8 and MCP-1 in THP-1 cells and the increase was strongly suppressed by Dc-3 extract, as compare with other extracts. Dc-3 also inhibited the release of IL-6 increased by mite extract and LPS in EoL-1 cells. However, Dc-3 extract increased IL-8 production induced by the mite extract and LPS in EoL-1 cells. These results suggest that Dc extract may be used as anti-inflammatory agents in treating allergic disorders such as asthma and atopic dermatitis.

Atopic dermatitis (AD) is a chronic inflammatory disease caused by immune dysregulation. Meanwhile, the supernatant of lactic acid bacteria (SL) was recently reported to have anti-inflammatory effects. In addition, HaCaT keratinocytes stimulated by tumor necrosis factor alpha (TNF-α) and interferon gamma (IFN-γ) are widely used for studying AD-like responses. In this study, we evaluated the anti-inflammatory effects of SL from lactic acid bacteria (LAB) on TNF-α/IFN-γ-induced HaCaT keratinocytes, and then we investigated the strains' probiotic properties. SL was noncytotoxic and regulated chemokines (macrophage-derived chemokine (MDC) and thymus and activation-regulated chemokine (TARC)) and cytokines (interleukin (IL)-4, IL-5, IL-25, and IL-33) in TNF-α/IFN-γ-induced HaCaT keratinocytes. SL from Lacticaseibacillus rhamnosus MG4644, Lacticaseibacillus paracasei MG4693, and Lactococcus lactis MG5474 decreased the phosphorylation of nuclear factor-κB (NF-κB) and mitogen-activated protein kinase (MAPK). Furthermore, the safety of the three strains was demonstrated via hemolysis, bile salt hydrolase (BSH) activity, and toxicity tests, and the stability was confirmed under simulated gastrointestinal conditions. Therefore, L. rhamnosus MG4644, L. paracasei MG4693, and Lc. lactis MG5474 have potential applications in functional food as they are stable and safe for intestinal epithelial cells and could improve atopic inflammation.

This study presents a comparative study for differences in efficacy and ingredient of white ginseng(WG), red ginseng(RG), and black ginseng(BG) using anti-oxidative activity test and anti-inflammatory activity test. In the results of cytotoxicity test for WG, RG, and BG, the survival rate of all cells was more than 95%. In the total polyphenol analysis, DPPH, ABTS radical scavenging test, and ROS production test, BG showed higher anti-oxidant activity than WG and RG. RG and WG showed higher inhibition activity of NO production and $PGE_2$ production, respectively. As results of the test for the effect on reduction of inflammatory cytokine production, WG and RG were effective on reduction of IL-$1{\beta}$ production, and BG was effective on reduction of IL-6. In the case of TNF-${\alpha}$ production, there was no difference among samples. This study could be useful basic data for the development of functional food and the fabrication of safe cosmetic.

Objective : This study was designed to identify lipid protection formation in stratum corneum and anti-inflammatory effects of Sopungdojeok-tang(SD) on atopic dermatitis(AD). Materials and Methods : In Vivo, SD extract was orally administered to BALB/c mice at $2.5m{\ell}/kg/day$ for 2 days after 5% sodium dodecyl sulfate evoked atopic dermatitis in abdominal skin. Morphological changes were observed by immunohistochemical stain using monoclonal antibodies(BrdU, ceramide, MIP-2, $NF-{\kappa}B$ p50, IL-4, and STAT6) and TUNEL method. In vitro, the alterations of IL-4 mRNA expression were detected by RT-PCT in SD extract treated EL4 cells after phorbol-12-myristate-13-acetate and 4-tert-Octylphenol induce Th2 skewed condition. Results : SD is used in Oriental Medicine for its potential curative for atopic dermatitis. In this study, we have investigated the anti-inflammatory and lipid lamella repair effects of SD were investigated. SD decreased the number of eosinophil in atopic dermatitis induced mice. In the histological properties, the hyperplasia, edema, infiltration of lymphocytes, damage of intercellular space of stratum corneum, BrdU positive reacted cells in stratum basal, and degranulated mast cells and capillaries in dermal papillae decreased in mice with SD. Treatment of SD also decreased MIP-2, STAT6 and IL-4 in dermal papillae. The IL-4 mRNA expression decreased in a dose-dependant manner in SD treated EL4 cells. In addition, decrease of $NF-{\kappa}B$ p50 and increase of apoptotic cells in dermis were observed in SD treated mice. These data suggest that SD may beneficial for atopic dermatitis. Conclusions : These data suggest that SD is beneficial in treatment of atopic dermatitis, and that SD provides lipid protection in stratum corneum and anti-inflammatory effects on atopic dermatitis.

This study was conducted to determine the anti-inflammatory effect of essential oil extracted from the wood of Chamaecyparis obtusa Sieb. et Zucc. Endl. (Cupressaceae). The essential oil was extracted from the wood of C. obtusa by hydrodistillation method, and conducted the analysis on the chemical composition of the extracted C. obtusa wood oil through GC-MS. The major constituents of the oil were found to be: ${\alpha}-pinene$ (11.4%), cadinene (5.4%), ${\delta}-cadiene$ (9.0%), ${\tau}-muurolol$ (22.2%), ${\alpha}-cadinol$ (20.8%) etc. We attempted to identify the anti-inflammatory activities of the oil when it is injected in the lipopolysaccharide (LPS)-stimulated RBL-2H3 cells, along with its effects on the secretion of interleukin-4 (IL-4), interleukin-13 (IL-13), ${\beta}-hexosaminidase$. According to the cell viability analysis conducted by MTT assay, the oil in $10^{-7}{\sim}10^{-5}%$concentration showed no effect on the cell viability. After RBL-2H3 cells treated by LPS stimulation were exposed to $10^{-7}%$ concentration of C. obtusa wood oil, the expression levels of IL-4, IL-13 within the cell were observed to remarkably decrease. Also, it was attenuated the release of ${\beta}-hexosaminidase$ from mast cells to a significantly meaningful level. These results suggest that C. obtusa wood oil exerts the anti-inflammatory effect, by regulating the expression of inflammatory cytokines, which is a valuable feature to be highly utilized as the functional materials in the future.

Inflammation plays an important role in host defense against external stimuli such as infection by pathogen, endotoxin or chemical exposure by the production of the inflammatory mediators that produced by macrophage. Anti-inflammatory factor is important to treat the dangers of chronic inflammation associated with chronic disease. This research aims to analyze the anti-inflammatory effects of Garcinia mangostana L. peel extract (GMPE), ${\alpha}$-mangostin, and ${\gamma}$-mangostin in LPS-induced murine macrophage cell line (RAW 264.7) by inhibiting the production of inflammatory mediators. The cytotoxic assay of G. mangostana L. extract, ${\alpha}$-mangostin, and ${\gamma}$-mangostin were performed by MTS (3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium) to determine the safe and non-toxic concentration in RAW 264.7 for the further assay. The concentration of inflammatory mediators (COX-2, IL-6, and IL-$1{\beta}$) were measured by the ELISA-based assay and NO by the nitrate/nitrite colorimetric assay in treated LPS-induced RAW 264.7 cells. The inhibitory activity was determined by the reducing concentration of inflammatory mediators in treated LPS-induced RAW 264.7 over the untreated cells. This research revealed that GMPE, ${\alpha}$-mangostin, and ${\gamma}$-mangostin possess the anti-inflammatory effect by reducing COX-2, IL-6, IL-$1{\beta}$, and NO production in LPS-induces RAW 264.7 cells.

The halophilic enterobacteria, Enterobacteria cancerogenus, was isolated from the intestines of the fusiform fish (Trachurus japonicus) to yield a protein-like material termed PLM-f74. PLM-f74 was characterized by strong inhibition ratios to angiogenesis (82.8% at the concentration of $18.5{\mu}g/mL$) and elevated antioxidative capacities with low toxicity. The PLM-f74 is a glycoprotein comprised of saccharides and amino acids. PLM-f74 inhibited non-activated U937 monocytic cell adhesion to HUVECs activated with IL-$1{\beta}$ by 78.0%, and the adherence of U937 cells treated with the PLM-f74 and stimulated with IL-$1{\beta}$ to unstimulated HUVECs decreased by 102%. When both cell types were pretreated with PLM-f74, the adhesion of U937 cells to IL-$1{\beta}$ stimulated HUVECs was completely suppressed by 121% at a concentration of 18.5 ug/mL. PLM-f74 blocked signal pathways from VEGFR2, PI3K, ${\beta}$-catenin and VE-cadherin to NF-kB based on western bolt analysis. And also inhibited IL-1-stimulated HUVEC expression of the adhesion molecules, ICAM-1 by 40%, VCAM-1 by 60%, and E-selectin by 70% at the same concentration noted above. New anti-angiogenic and anti-cell adhesion materials showing elevated antioxidative capacities and non-toxicity may be expected from these results.
