Effect of brine mineral water(BMW) on contact hypersensitivity reaction(CHR) was estimated using trimellitic anhydride (TMA) induced CHR in the mouse. BMW exhibited potent inhibitory activity on TMA induced CHR. BMW treatment suppressed the ear swelling, and attenuated hyper-activated lymph nodes stimulated by TMA challenge, thereby reduced their weight. The immunological index was analyzed after BMW administration in CHR. The level of serum IgE was significantly down regulated after BMW treatment. Furthermore, BMW showed inhibitory property of cytokine production. BMW treatment suppressed not only Th2 type cytokine, IL-4 but also pro-inflammatory cytokines such as TNF-${\alpha}$ and IL-6. From the histological analysis, the inflammatory context appeared by atopic dermatitis lesion after challenging with TMA are diminished by BMW treatment. Our results suggest that BMW may attenuate the development of CHR, and can be available for functional ingredient.

The purpose of this study was to select the absorbable suture material with the lowest level of foreign body reaction in the extraoral field. The absorbable sutures tested were polyglactin 910(Vicryl), polyglycolic acid(Dexon), and chromic gut. Black silk served as to control suture. Eighteen domestic rabbits served as the animal model for testing purposes. After shaving the fur, A six centimeter incision was made in the hind quarter of all eighteen animals. Each wound was then closed wit two Vicryl, two Dexon, and two chromic gut sutures. All wounds were closed in the same manner. A similar wound was made on the oppsite side and closed with black silk suture. Three rabbits were then sacrificed on postoperative day one, three, seven fourteen, twenty-one, and twenty-eight. The surgical sites were then examined histologically. 1. On days one, three, and seven all suture materials as a similar severe level of inflammatory response. On the fourteenth day the inflammatory reaction of Vicryl was minimal, chromic gut was moderate, and Dexon was severe, Black silk control groups demosnstrated the most severe levels of inflammation of all sutures tested from day fourteen to twenty-eight. 2. On the fourteenth day all absorbable suture materials demonstrated similar minimal levels of resorption. At twenty-eight days Vicryl demonstrated a greater amount of resorption than Dexon or cromic gut suture. There was no resorption noted in the black silk control groups through day twenty-eight. 3. Due to its decreased level of inflammatory response in the animal model, Vicryl might be expected to as a decreased level of response in humans. It is felt that Vicryl is preferred to Dexon or chromic gut for extraoral suturing.

1. Objectives The roots of Sophora flavescens Aiton (SFA) are widely used as a herbal remedy for allergic inflammation. In this study, we invested the effect of SFA on passive cutaneous anaphylaxis reaction and histamin releas and we demonstrated that SFA suppressed the production of pro-inflammatory cytokines, such as tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), interleukin- 6 (IL-6), and interleukin -8 (IL-8), through inhibition of the $NF{\kappa}B$, JNK and p38 pathway in the human mast cell line, HMC-1. 2. Methods To accomplish this, we invested passive cutaneous anaphylaxis reaction and histamin release at an animal experiment. In addition, we investigated the effect of SFA on the production of inflammation-related cytokines in HMC-1 cells that were co-treated with PMA and A23187, which can induce production of pro-inflammatory cytokines. 3. Results and Conclusions SFA induced passive cutaneous anaphylaxis reaction and histamin releas and supressed the expression of TNF-${\alpha}$, IL-6, and IL-8. In addition, the protein levels of TNF-${\alpha}$ were also decreased by SFA treatment. Furthermore, SFA inhibited the nuclear translocation of nuclear factor $NF{\kappa}B$ through inhibition of the phosphorylation and degradation of $I{\kappa}B-{\alpha}$, which is an inhibitor of $NF{\kappa}B$. Moreover, SFA also inhibited induction of MAPKs (JNK, p38) and $NF{\kappa}B$ promoter-mediated luciferase activity. Taken together, these results suggest that SFA could be used as a treatment for mast cell-derived allergic inflammatory diseases.

Saengjihwangeum-ja (SJHEJ) was recorded in DongEuiBoGam as being able to be used for treatment of Sogal whose concept had been applied to Diabetes Mellitus (DM). Modification of proteins by long term circulation of glucose leads to the formation of advanced glycation end product(AGE). Recent immunological studies demonstrated that ligation of AGE play an important role in the development of diabetic complications including atherosclerosis, which includes activation, adhesion, and migration of monocytes. Also, AGE and Maillard reaction product(MRP) could augment monocyte inflammatory responses via ligation of AGE receptor. In this study, the effects of SJHEJ extracts on the expression of inflammatory response-related genes such as tumor necrosis factor-$\alpha$, monocyte chemoattractant protein-1, interferon-g-inducible protein-10, and cyclooxygenase-2 in the human monocyte cell line, THP-1 cells. Reverse transcriptase-polymerase chain reaction revealed that SJHEJ had inhibitory effects on the expression of the TNF-a, MCP-1, IP-10, COX2, IL-1b genes in MRP-induced THP-1 cells. Treatment with SJHEJ had reduced reactive oxygen production in THP-1 cells stimulated by MRP. These inhibitory effects might be exerted via prevention of oxidative stress in activated monocytes. In addition, radical scavenging activity of SJHEJ was increased. These results suggest that SJHEJ has a beneficial effects for improve diabetic vascular complication.

With the rapid developments in nanotechnology, an increasing number of nanomaterials have been applied in various aspects of our lives. Recently, pharmaceutical nanotechnology with numerous advantages has growingly attracted the attention of many researchers. Zinc oxide nanoparticles (ZnO-NPs) are nanomaterials that are widely used in many fields including diagnostics, therapeutics, drug-delivery systems, electronics, cosmetics, sunscreens, coatings, ceramic products, paints, and food additives, due to their magnetic, catalytic, semiconducting, anti-cancer, anti-bacterial, anti-inflammatory, ultraviolet-protective, and binding properties. The present review focused on the recent research works concerning role of ZnO-NP on inflammation. Several studies have reported that ZnO-NP induces inflammatory reaction through the generation of reactive oxygen species by oxidative stress and production of inflammatory cytokines by activation of nuclear factor-${\kappa}B$ ($NF-{\kappa}B$). Meanwhile, other researchers reported that ZnO-NP exhibits an anti-inflammatory effect by inhibiting the up-regulation of inflammatory cytokines and the activation of $NF-{\kappa}B$, caspase-1, $I{\kappa}B$ $kinase{\beta}$, receptor interacting protein2, and extracellular signal-regulated kinase. Previous studies reported that size and shape of nanoparticles, surfactants used for nanoparticles protection, medium, and experimental conditions can also affect cellular signal pathway. This review indicated that the anti-inflammatory effectiveness of ZnO-NP was determined by the nanoparticle size as well as various experimental conditions. Therefore, the author suggests that pharmaceutical therapy with the ZnO-NP is one of the possible strategies to overcome the inflammatory reactions. However, further studies should be performed to maximize the anti-inflammatory effect of ZnO-NP to apply as a potential agent in biomedical applications.

Background: Adipocyte-macrophage communication plays a critical role regulating white adipose tissue (WAT) inflammatory gene expression. Because WAT inflammation contributes to the development of metabolic diseases, there is significant interest in understanding how exogenous compounds regulate the adipocyte-macrophage crosstalk. An aqueous (AQ) extract of North American (NA) ginseng (Panax quinquefolius) was previously shown to have strong inflammo-regulatory properties in adipocytes. This study examined whether different ginseng extracts influence adipocyte-macrophage crosstalk, as well as WAT inflammatory gene expression. Methods: The effects of AQ and ethanol (EtOH) ginseng extracts ($5{\mu}g/mL$) on adipocyte and macrophage inflammatory gene expression were studied in 3T3-L1 and RAW264.7 cells, respectively, using real-time reverse transcription polymerase chain reaction. Adipose tissue organ culture was also used to examine the effects of ginseng extracts on epididymal WAT (EWAT) and inguinal subcutaneous WAT (SWAT) inflammatory gene expression. Results: The AQ extract caused significant increases in the expression of common inflammatory genes (e.g., Mcp1, Ccl5, Tnf-${\alpha}$, Nos2) in both cell types. Culturing adipocytes in media from macrophages treated with the AQ extract, and vice versa, also induced inflammatory gene expression. Adipocyte Ppar-${\gamma}$ expression was reduced with the AQ extract. The AQ extract strongly induced inflammatory gene expression in EWAT, but not in SWAT. The EtOH extract had no effect on inflammatory gene expression in either both cell types or WAT. Conclusion: These findings provide important new insights into the inflammo-regulatory role of NA ginseng in WAT.

Purpose : Human gingival fibroblast cell is one of the the main cell types in periodontal tissue, which they can show anti-inflammatory activity through the production of numerous lines of inflammatory mediators such as inducible nitric oxide synthase (iNOS), cyclooxygenase (COX)-2 and interleukins. Porphyromonas gingivalis, one of the oral pathogens, has reported to play a critical role in the development of periodontal diseases. This study aimed to investigate anti-inflammatory and antioxidative activities of Gracilaria textorii ethanol extract (GTEE) in P. gingivalis derived lipopolysaccharide (LPS-PG) stimulated human gingival fibroblast (HGF)-1 cell line. Methods : In order to analyze anti-inflammatory and antioxidative activities of GTEE in HGF-1 cell line, NOS enzyme activity, expression levels of iNOS, COX-2, NAD(P)H quinone dehydrogenase (NQO)1 and their transcription factors were estimated by Griess reaction and western hybridization. Results : LPS-PG induced overexpression of iNOS and COX-2, which was significantly attenuated by GTEE treatment in a dose-dependent manner without any cytotoxicity. In addition, intracellular NOS activity was in accordance with the result of iNOS expression. Due to important role in the regulation of inflammatory responses, phosphorylated status of p65 and c-jun, each subunit of nuclear factor (NF)-κB and activator protein (AP)-1, was also dose-dependently ameliorated by GTEE treatment. One of phase II enzymes, NQO1, and its transcription factor, nuclear factor erythroid 2-related factor 2 (Nrf2), were analyzed since elevated phase II enzyme expression inhibited inflammatory response, which was significantly elevated by GTEE treatment in HGF-1 cell line. Conclusion : In conclusion, GTEE mitigated LPS-PG-stimulated inflammatory responses by attenuating NF-κB and AP-1 activation as well as accelerating NQO1 and Nrf2 expression in HGF-1 cell line. These results indicate that GTEE might be utilized a promising strategy for potential anti-inflammatory agent in periodontal diseases.

The stems and branchs of Euryale ferox Salisbury (EF), are used in Chinese herbal medicine for latent-heat-clearing, antipyretic, detoxicant and anti-inflammatory ailments. This plant is used worldwide for the treatment of many types of inflammatory disease including respiratory infections, diabetes mellitus, rheumatoid arthritis and play an important role in the immune reaction. Topical natural antioxidants are a useful strategy for the prevention of oxidative stress mediated inflammatory disease. Plants produce significant amounts of antioxidants to prevent the oxidative stress caused by photons and oxygen, therefore they represent a potential source of new compounds with antioxidant activity. This study was designed to evaluate whether EFEA (ethylacetate fraction of EF) may ameliorate oxidative stress and inflammatory status through the antioxidative mechanism in LPS-stimulated RAW 264.7 murine macrophage cell line. Treatment of RAW 264.7 cells with EFEA significantly reduced LPS-stimulated inflammatory response in a dose-dependent manner. In conclusion, the EF extracts have anti-inflammatory effects in vitro system, which can be used for developing pharmaceutical drug against oxidative stress and chronic inflammatory disease.

Donggwaja (Benincasae Semen), the seed of Benincasa hispida (Thunb.) Cogn., has been used in Korean traditional medicine to control the body heat and water retention caused by various diseases. Both the symptoms targeted by the herbal medicine in clinic and studies with disease mouse models support the potential anti-inflammatory effect of Donggwaja. However, it is less understood how Donggwaja exerts its possible anti-inflammatory effect. Here, we present evidence that Donggwaja suppresses macrophage inflammatory reactions via expressing tumor necrosis factor a-induced protein 3 (TNFAIP3 or A20) and suppressing NF-kB activity. The ethanol extract of Donggwaja (EED) showed no toxicity when added to RAW 264.7 cells less than 100mg/ml. When treating the cells for 16 h, EED significantly suppressed the nuclear localization of NF-kB, suggesting that EED suppresses NF-kB activity. Concordantly, a semi-quantitative RT-PCR analysis showed that EED decreased the expression of prototypic pro-inflammatory cytokines, such as tumor necrosis factor (TNF)-a, IL(interleukin)-6, and IL-1b. EED induced in RAW 264.7 cells the expression of A20, a ubiquitin modulator that suppresses inflammatory signaling cascades initiated from TLR4 and TNF and IL-1 receptors, while not affecting the induction of Nrf2, an anti-inflammatory factor that could suppress the effect of NF-kB. These results suggest that EED exerts its suppressive effect on inflammation, at least in part, by expressing anti-inflammatory factor A20 and suppressing pro-inflammatory factor NF-kB activity.
