Xanthone is a kind of polyphenolic compounds that contain a distinctive chemical structure with a tricyclic aromatic ring found in a few higher plant families e.g. gentian root. This compound had a variety of biological activity, for instance antioxidant, antibacterial, anti-inflammatory, and anticancer effects. However, the effect of xanthone on mast cell-mediated allergic inflammation and its associated mechanism have not been elucidated. Therefore, the aim of this study was to elucidate the anti-allergic inflammatory effects and the underlying molecular mechanism of xanthone in PMACI-stimulated human mast cells-1 (HMC-1). In this result, xanthone treatment decreased the production of histamine, pro-inflammatory cytokines such as tumor necrosis factor-a (TNF-${\alpha}$), IL-6, and IL-8 and expressions of TSLP in PMACI-stimulated HMC-cells. In addition, xanthone significantly suppressed the phosphorylation of MAPKs and the activation of NF-${\kappa}B$ signal pathway in activated mast cells. Furthermore, xanthone inhibited the activation of caspase-1, an IL-$1{\beta}$ converting enzyme, in PMACI-stimulated HMC-1 cells. These findings provide evidence that xanthone could be a potential therapeutic agent for allergy-related inflammatory disorders.

Objective : The aim of this experimental study was to investigate the anti-diarrhea effects of Jisa-tang using mice and guinea pigs. Methods : We feed Jisa-tang to mice and guinea pigs to investigate its effects for anti-diarrhea action. We observed its actions on gastrointestinal smooth muscles, on the transportability of small and large intestines, on diarrhea induced by castor oil and magnesium sulfate, and on enteropooling by castor oil and prostaglandin $E_2(PGE_2)$. Results : 1. Jisa-tang showed alleviation, depending on the density, only on the contraction of mice's gastrointestinal smooth muscles induced by histamine. 2. The transportability of the small intestine was not significantly constrained by Jisa-tang. However, the enhancement of pyridostigmine-induced transportability of he small intestine was significantly constrained in the group administered 900mg/kg of Jisa-tang (p<0.05). 3. The transportability of large intestine was significantly constrained in the group administered 1,800mg/kg of Jisa-tang. 4. Jisa-tang showed significant anti-diarrhea effects on diarrhea induced by castor oil and by $MgSO_4$ in the group administered 1,800mg/kg of Jisa-tang. 5. Significant reduction of effects of enteropooling induced by caster oil and by prostaglandin $E_2$ were observed only in the group administered 1,800mg/kg of Jisa-tang. Conclusions : We conclude that Jisa-tang has advantageous effects on drug-induced diarrhea and will contribute to the development of diarrhea treatment through further related studies.

Objective : The genus Glycyrrhiza has been used in food and traditional herbal medicine. Many experimental studies reported that Glycyrrhiza species possess several pharmacological properties. Glycyrrhiza new varieties WONGAM and SINWONGAM have been developed by Korea Rural Development Administration doing research for registration on Ministry of Food and Drug Safety. During the evaluations about pharmacological effect of Glycyrrhiza new varieties WONGAM and SINWONGAM, we focused the anti-allergic effect in this study. Methods : We investigated the anti-allergic effect of WONGAM and SINWONGAM compared with Glycyrrhiza uralensis Fischer and G. glabra L. using anti-dinitrophenyl-immunoglobulin E (IgE)/human serum albumin-stimulated RBL-2H3 cells, phorbol 12-myristate 13-acetate plus calcium ionophore A23187-stimulated HMC-1 cells and compound 48/80-induced anaphylaxis mice model. We analyzed the effect on the expression of various cytokines, and IgE from mast cells and the underlying molecular mechanisms of WONGAM and SINWONGAM in presented models. Results : WONGAM and SINWONGAM showed the inhibitory effect on the histamine release from rat peritoneal mast cells or human mast cells without cytotoxicity. WONGAM and SINWONGAM blocked anaphylactic shock and decreased the IgE production. Furthermore, WONGAM and SINWONGAM inhibited the productions of TNF-α and IL-6 in compound 48/80-induced anaphylaxis mice model. Conclusion : These results indicated that WONGAM and SINWONGAM would have protect effect on allergic responses through the inhibition of allergic mediators and pro-inflammatory cytokines. This study may facilitate the development on Glycyrrhiza new varieties for allergy.

본 연구에서 장류 및 젓갈 유래 균체를 각각 sonication, $100^{\circ}C$에서 30 min, $125^{\circ}C$에서 15 min의 조건으로 추출하여 HMC-1에 처리하였을 때, 이 추출방법에 따른 HMC-1매개 염증반응 억제효과를 조사하였다. 추출방법을 달리하여 추출한 장류 및 젓갈 유래 균체 J80, G147이 HMC-1생존율에 미치는 영향은 대조구 B (Not treated)와 비교하였을 때 86~96%로 유의적 차이를 보이지 않아 장류 및 젓갈 유래 균체에 의한 세포 독성은 나타나지 않았다. 장류 및 젓갈 유래 균체의 모든 전처리구에서 histamine 유리 억제효과를 나타내었으며 특히, $100^{\circ}C$에서 30 min 동안 가열하였을 때 histamine 억제율이 J80에서 28.86%, G147에서 41.14%으로 가장 높게 나타냈다. IL-8 분비량은 J80, G147의 모든 전처리구에서 IL-8 분비억제효과가 나타났으며, J80의 경우 $100^{\circ}C$, 30 min에서 처리한 구에서 분비량이 0.78 ng/ml로 대조구 B (Not treated)에 비하여 약 28.45%의 분비억제효과로 가장 높게 나타내었다. G147의 경우 $125^{\circ}C$, 15 min에서 처리한 구에서 분비량이 0.73 ng/ml로 약 36.52%의 분비억제효과로 가장 높게 나타내었다. IL-6 분비량을 측정한 결과 J80, G147의 모든 실험구에서 IL-6 분비억제효과가 나타났으며, J80에서는 $100^{\circ}C$, 30 min한 D구의 분비량이 0.40 ng/ml으로 대조구 B (Not treated)에 비하여 약 38.46%의 분비억제효과로 가장 높았으며, G147 역시 $100^{\circ}C$, 30 min 동안 처리한 D구의 분비량이 0.27 ng/ml으로 대조구 B (Not treated)에 비하여 56.45%의 분비억제효과로 가장 높게 나타냈다. TNF-${\alpha}$ 분비량 역시 IL-6와 마찬가지로 J80, G147에서 대조구 B보다 낮은 분비량으로 TNF-${\alpha}$ 분비 억제효과가 나타났으며 J80의 경우 $100^{\circ}C$, 30 min 처리한 D의 TNF-${\alpha}$ 분비량이 0.052 ng/ml으로 66.67%의 분비억제효과로 가장 높았으며, G147의 경우 sonication을 처리한 C구의 TNF-${\alpha}$ 분비량이 0.086 ng/ml으로 41.1%의 분비억제효과로 다른 구에 비해 높은 억제효과를 나타내었다. 위의 결과를 통해서 장류 및 젓갈 유래 균체의 3가지 전처리 방법 중 $100^{\circ}C$, 30 min 처리 시 염증 반응 억제 효과가 가장 높을 것으로 예상된다. 결과를 미루어보아 장류를 섭취하는 대표적인 방법인 가열하여 찌개로 조리과정 중 장류 및 젓갈 속의 균체가 열에 가열되면서 염증억제효과 높일 수 있는 가장 좋은 조리 방법으로 사료되며, 이는 대중들이 가장 가깝게 염증반응 억제효과를 볼 수 있는 식품일 것이다. 또한 염장처리과정만을 거친 젓갈을 섭취하는 것보다 열처리과정을 거친 젓갈을 섭취할 경우 염증억제효과를 더 높일 수 있을 것으로 예상된다.

Antiscratching behavioral effects of the water extract of two black colored rice (BCR) varieties [Oryza sativa L. cv. Heugjinjubyeo (HJ) and Josaengheugchalbyeo (JH)], major pigment of which is cyanindin 3-glucoside, were investigated. Orally administered BCRs' extracts exhibited potent inhibitory activity against scratching behaviors which were induced by compound 48/80 and histamine. The inhibitory effect of Josaengheugchalbyeo in vivo and in vitro were more potent than those of Heugjinjubyeo. These finding suggest that black colored rice, especially Josaengheugchalbyeo, may inhibit scratching behaviors and anaphylaxis reaction by stabilizing membrane.

Purpose : The objective of present study is to detect the effect of Sopungsan aqueous extracts (SPS) on the passive cutaneous anaphylaxis (PCA; type I allergic dermatitis) Method : 500, 250 and 125mg/kg of SPS were orally administered 12 hr-interval before antigen challenge (total 4 times administered). PCA reactions were induced using rat anti-ovalbumin (OVA) serum contain IgE (titer 1:32) as sensitization and OVA as antigen challenge. 30 min after antigen challenge, the diameter of blue-dye spots (evans blue) and leaked amount of dye were observed with histology and histomorphometry at the PCA induced sites. In addition, serum total IgE and histamine levels were also observed by ELISA, respectively. The effects of SPS were compared with dexamethasone 1mg/kg treated rats in the present study. Results : As results of PCA reaction, vasodilation related increase of diameter of blue-dye spot and amount of leaked dye were observed with swelling and edematous changes in the dermis of PCA induced sites. However, these changes on PCA reactions were dramatically and dose-dependently decreased by treatment of SPS as compared with vehicle control. In addition, serum elevations of IgE and histamine were also dose-dependently inhibited by treatment of SPS as compared with vehicle control respectively. The effects of SPS 500mg/kg were similar to that of dexamethasone 1mg/kg in the present study. Conclusion : Base on the results of the present study, it is concluded that SPS has favorable effect on the PCA-induced allergic dermatitis, and SPS 500mg/kg showed similar favorable effects as compared with dexamethasone 1mg/kg. The present findings demonstrate that SPS can be effective for the prevention and treatment of allergic dermatitis.

The purpose of this study was to investigate the anti-allergy activities of persimmon leaf extract (PLE) on a phthalic anhydride (PA)-induced allergic mouse model. A human leukemic mast cell line (HMC-1) was used to examine the inhibitory activity of PLE on the histamine release by human leukemic mast cells. PLE inhibited histamine release from HMC-1 cells in response to cross-linkage of high-affinity IgE receptor-${\alpha}$ ($Fc{\varepsilon}RI{\alpha}$). Additionally, a PA-induced allergic mouse model was used to investigate the effects of PLE in vivo. Mice were orally administrated with or without PLE of single dose (250 mg/kg/day) for 31 days. Oral intake of PLE significantly inhibited passive cutaneous reactions. Oral administration of PLE to PA-induced allergic mice also led to a striking suppression of the development of contact dermatitis, ear swelling and lymph node weight. In addition, PA-specific IL-4 production of draining lymph node cells was markedly diminished by PLE oral administration, but not IFN-${\gamma}$. Furthermore, PLE treatment suppressed PA-induced thymus and activation-regulated chemokine (CCL17) and cutaneous T cell-attracting chemokine (CCL27) expressions in ear tissues. Based on these results, we suggest that PLE may have therapeutic potential as an effective material for management of irritant contact dermatitis or related inflammatory diseases.

Objectives : Scutellaria barbata has been widely used in oriental medicine used for treatment of acute and chronic inflammatory diseases. In this study, to investigate the protective effect of Scutellaria barbata on type I allergic response, we determined whether Scutellaria barbata inhibits early or late allergic responses. Methods : To assess the effect of Scutellaria barbata Pharmacopuncture Extract(SB) in RBL-2H3 cells, we investigated the levels of the markers of degranulation such as ${\beta}$-hexosaminidase and histamine, inflammatory mediator such as IL-4, TNF-${\alpha}$, PGE2 and cysLT, and mRNA expression of cytokines and enzymes. In addition, we determined the levels of intracellular ROS by DCFH-DA assay and the free radical scavenging activity by DPPH method. Results : We found that SB suppressed the release of ${\beta}$-hexosaminidase and histamine and the production of IL-4, TNF-${\alpha}$, PGE2 and cysLT in RBL-2H3 by the antigen stimulation. SB also significantly inhibited the enzyme mRNA expressions, such as HDC2, COX-1, COX-2, 5-LOX and iNOS2, along with reduced cytokine mRNA expressions, such as IL-$1{\beta}$, IL-2, IL-3, IL-4, IL-5, IL-6, IL-13, TNF-${\alpha}$ and GM-CSF in RBL-2H3. In addition, SB suppressed the levels of intracellular ROS. Conclusions : Our results indicate that SB protects against type I allergic response and exert an anti-inflammatory effect through the inhibition of degranulation, inflammatory mediator release and mRNA expression of cytokines and enzymes.
