Soy sauce is a traditional fermented seasoning in several oriental countries, such as Korea and Japan, and recently it has been reported to have biological activities. In Korean soy sauce, soybeans and wheat are the two main raw materials. Polysaccharides that originate from the cell wall of soybeans are resistant to enzymatic hydrolysis. These polysaccharides remain in the soy sauce even after fermentation and are termed Kanjang polysaccharides (KPS). In this study, polysaccharides were obtained from dialysate of different soy sauces labeled as A~T and manufactured by fermentation or the acid-hydrolyzate method. We investigated anti-inflammatory activities by examining the effects of these KPS on proinflammatory cytokine release and mRNA expression in mast cells. Histamine and ${\beta}$-hexosaminidase release were strongly decreased by the KPS treatment in RBL-2H3 cells. Treatment with KPS clearly reduced mRNA expression and the release of the proinflammatory cytokines interleukin (IL)-6, IL-8, and tumor necrosis factor-alpha (TNF-${\alpha}$) in PMACI-stimulated HMC-1 cells. In particular, KPS derived from fermented Kanjang products showed a significant anti-inflammation effect on mast cells compared to the acid-hydrolyzed Kanjang products. This study suggests that KPS appear to be effective in suppressing allergic inflammatory reactions.

비만세포의 한 종류인 rat basophilic leukemia (RBL-2H3) 세포를 이용하여 교계사물탕-가감의 항알레르기 효과를 확인하고자 하였다. Phorbol 12-myristate 13-acetate (PMA)와 calcium ionophore A23187을 이용하여 RBL-2H3 세포를 자극한 후 세포의 탈과립 정도를 $\beta$-hexosaminidase assay로 확인한 결과, 전 처리한 교계사물탕-가감의 농도 의존적으로 탈과립을 억제하였다. Pro-inflammatory cytokines인 tumor necrosis factor (TNF)-alpha와 interleukin(IL)-4의 분비량을 enzyme-linked immunosorbent assay (ELISA)로 확인한 결과 교계사물탕-가감의 농도 의존적으로 감소하였으며, 이들 cytokines와 염증 반응에 주요한 인자인 cyclooxygenase (COX)-2 의 mRNA 발현 정도 역시 교계사물탕-가감에 의해 감소함을 확인할 수 있었다. 이러한 실험 결과로 보아 교계사물탕-가감은 알레르기 관련 질환의 치료에 응용될 수 있을 것으로 사료된다.

Yeonguemjiri-tang(連芩止痢湯, YGT) exhibits potent anti-inflammatory activity in widely intestine disease, but its mechanism undisclosed. To elucidate the molecular mechanisms of YGT on pharmacological and biochemical actions in inflammation, we examined the effect of YGT on pro-inflammatory mediators in phorbol 12-myristate 13-acetate (PMA) plus A23187-induced mast cell and lipopolysaccharide (LPS)-stimulated macrophages. The investigation focused on whether YGT inhibited pro-inflammatory cytokines such as interleukin-6 (IL-6), interleukin-8 (IL-8), tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) in PMA plus A23187-induced HMC-1 cells and inflammatory madiators such as nitric oxide (NO), TNF-${\alpha}$, IL-6, iNOS, COX-2 in LPS-stimulated RAW 264.7 cells. We found that YGT inhibited LPS-induced NO, TNF-${\alpha}$ and IL-6 productions as well as the expressions of iNOS and COX-2. These results suggest that YGT has inhibitory effects on mast cell-mediated and macrophage-mediated inflammation.

Samultang has been believed for prevention and remedy various blood diseases such as menstrual irregularity, anemia, and metrorrhagia. However, the mechanism that accounts for anti-inflammatory effects of the Samultang is still not fully understood. This study was designed to evaluate whether and how the Samultang could modulate the production of pro-inflammatory cytokines in phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore A23187 treated-human mast cell line, HMC-1. Samultang inhibited the production of tumor necrosis factor $(TNF)-\alpha$, interleukin (IL)-6, granulocyte macrophage colony stimulating factor (GM-CSF), and vascular endothelial growth factor (VEGF) in HMC-1. Maximal inhibition rate of $TNF-\alpha$, IL-6, GM-CSF, and VEGF by 0.1 mg/ml Samultang was about $70.73{\pm}3.0%,\;51.49{\pm}4.14%,\;54.03{\pm}2.09%$, and $47.95{\pm}7.86%$, respectively. Samultang partially blocked PMA plus A23187-induced cyclooxygenase (COX)-2 expression. In addition, Samultang inhibited activation of nuclear factor (NF)-kB, and extracellular signal-regulated kinase (ERK) activation. These results suggest that anti-inflammatory effect of Samulatng may be mediated by the suppression of cytokine production and COX-2 activation via down-regulation of NF-kB and ERK activation.

Jakyaktang(芍藥湯; JYT) exhibits potent anti-inflammatory activity in widely intestinal disease, but its mechanism was undisclosed. To elucidate the molecular mechanisms of JYT on pharmacological and biochemical actions in inflammation, we examined the effect of JYT on pro-inflammatory mediators in phorbol 12-myristate 13-acetate (PMA) plus A23187-induced mast cell and lipopolysaccharide (LPS)-stimulated macrophages. The investigation focused on whether JYT inhibited pro-inflammatory cytokines such as interleukin-6 (IL-6), interleukin-8 (IL-8), tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) in PMA plus A23187- induced HMC-1 cells and inflammatory madiators such as nitric oxide (NO), TNF-${\alpha}$, IL-6, iNOS, COX-2 in LPS-stimulated RAW 264.7 cells. We found that JYT inhibited LPS-induced NO, TNF-${\alpha}$ and IL-6 productions as well as the expressions of iNOS and COX-2. These results suggest that JYT has inhibitory effects on mast cell-mediated and macropage-mediated inflammation.

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.

Background: To increase the pharmacological effects of red ginseng (RG, the steamed root of Panax ginseng Meyer), RG products modified by heat process or fermentation have been developed. However, the antiallergic effects of RG and modified/fermented RG have not been simultaneously examined. Therefore, we examined the allergic rhinitis (AR)-inhibitory effects of water-extracted RG (wRG), 50% ethanol-extracted RG (eRG), and bifidobacteria-fermented eRG (fRG) in vivo. Methods: RBL-2H3 cells were stimulated with phorbol 12-myristate-13-acetate/A23187. Mice with AR were prepared by treatment with ovalbumin. Allergic markers IgE, tumor necrosis factor-${\alpha}$, interleukin (IL)-4, and IL-5 were assayed in the blood, bronchoalveolar lavage fluid, nasal mucosa, and colon using enzyme-linked immunosorbent assay. Mast cells, eosinophils, and Th2 cell populations were assayed using a flow cytometer. Results: RG products potently inhibited IL-4 expression in phorbol 12-myristate-13-acetate/A23187-stimulated RBL-2H3 cells. Of tested RG products, fRG most potently inhibited IL-4 expression. RG products also alleviated ovalbumin-induced AR in mice. Of these, fRG most potently reduced nasal allergy symptoms and blood IgE levels. fRG treatment also reduced IL-4 and IL-5 levels in bronchoalveolar lavage fluid, nasal mucosa, and reduced mast cells, eosinophils, and Th2 cell populations. Furthermore, treatment with fRG reduced IL-4, IL-5, and IL-13 levels in the colon and restored ovalbumin-suppressed Bacteroidetes and Actinobacteria populations and ovalbumin-induced Firmicutes population in gut microbiota. Treatment with ginsenoside Rd significantly alleviated ovalbumin-induced AR in mice. Conclusion: fRG and ginsenoside Rd may alleviate AR by suppressing IgE, IL-4, IL-5, and IL-13 expression and restoring the composition of gut microbiota.

Objectives : This study was conducted to investigate the effects of Gwakhyangjeonggi-san(GJS) on atopic dermatitis(AD) induced by 2,4-dinitrochlorobenzene(DNCB) in mice. Methods : The mice(Balb/c mice) were divided into three groups; normal Balb/c mice with oil treatment(Sham group), DNCB-induced AD mice(AD group), and GJS treated AD mice(GJS group). GJS group were orally administered GJS daily for 2 weeks. We observed changes of clinical skin severity score, the expression of thymic stromal lymphopoietin(TSLP), interleukin(IL)-4 and tumor necrosis factor(TNF)-${\alpha}$ in skin and mast cell infiltration. Also, serum immunoglobulinE(IgE), IL-4, $TNF-{\alpha}$ and IL-6 were evaluated. Results : The clinical skin severity score of GJS group was decreased compared to AD group. In hematoxylin and eosin staining results, GJS group showed a significant reduction of epithelial skin thickness. In addition, expression of TSLP and mast cell infiltration in skin were also reduced by GJS treatment compared to those of AD group. Thus, we evaluated expression of IL-4, Th2-dependent cytokine, and $TNF-{\alpha}$, pro-inflammatory cytokine in skin. GJS significantly reduced both IL-4 and $TNF-{\alpha}$ compared to AD mice. Moreover, levels of IgE, IL-4, $TNF-{\alpha}$ and IL-6 in plasma also significantly decreased by oral GJS treatment. Conclusion : The present study suggests that GJS can significantly reduced symptoms of AD, therefore it can be a promising candidate for anti-atopic dermatitis treatment.

The stems of Dendrobium moniliforme are used in traditional Oriental medicine as a Yin tonic to nourish the stomach, promote the production of body fluid, and reduce fever. This study investigated the effects of the aqueous extract of D. moniliforme stems (DME) on mast cell degranulation and the expression of tumor necrosis factor-α (TNF-α), interleukin-4 (IL-4), and histamine-synthesizing enzyme histidine decarboxylase (HDC). We used rat mast cell line RBL-2H3 cells and stimulated them with PMA plus calcium ionophore (PMACI). Pretreatment with DME significantly inhibited PMACI-induced β-hexosaminidase release and the expression of TNF-α, IL-4, and HDC. Furthermore, DME suppressed PMACI-induced nuclear translocation of the nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) and activator protein 1 (AP-1). In addition, HDC expression was inhibited by SP600125 (JNK inhibitor), PD98059 (ERK inhibitor), and SB203580 (p38 kinase inhibitor). Finally, the phosphorylation of p38 kinase, extracellular signal-regulated kinase 1/2 (ERK1/2), and c-Jun N-terminal kinase (JNK) was inhibited by pretreatment with DME. These results suggest that DME has inhibitory effects against degranulation, cytokine (TNF-α and IL-4) and HDC expression, and that HDC expression is mediated by MAPK signaling. These findings suggest that DME may have therapeutic potential in the treatment of hypersensitive and inflammatory diseases.

Objectives : This study was to evaluate the anti-inflammatory and anti-pruritic effects of WSY-1075 composited with Corni Fructus, Angelica gigantis Radix, Lycii Fructus, Ginseng Radix, Cervi parvum Cornu and Cinnamomi Cortex in rat peritoneal mast cells (RPMCs) and scratching mouse model. Methods : WSY-1075 was prepared by extracting with 30% ethanol. In the present study, we investigated the effect of WSY-1075 on the production of tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), interleukin-$1{\beta}$ (IL-$1{\beta}$) and histamine in rat peritoneal mast cells (RPMCs) activated with phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore A23187, and on the scratching behavior in mice treated with pruriogens. Results : WSY-1075 was not cytotoxic effect in used all concentration. PMA plus A23187 treatment significantly increased TNF-${\alpha}$, IL-$1{\beta}$ and IL-6 production compared with media control in RPMCs. However, TNF-${\alpha}$, $IL1{\beta}$ and IL-6 production increased by PMA plus A23187 treatment were significantly inhibited by WSY-1075 (200 ${\mu}g/mL$ and 400 ${\mu}g/mL$). WSY-1075 also inhibited the histamine release from RPMCs stimulated by compound 48/80, which promotes histamine release. Moreover, WSY-1075 administration had an inhibitory effects on the scratching behavior induced by pruritogen (compound 48/80, histamine, serotonin and substence P) in ICR mice. Conclusion : These results suggest that WSY-1075 administration (200 mg/kg or 400 mg/kg) has the anti-inflammatory and anti-pruritic effects on the activated rat peritoneal mast cell and mouse pruritus. WSY-1075 has a potential use as a composition of medicinal plants for treatment against inflammation- and pruritus-related disease.
