방사선에 대한 방호와 면역기능 조절을 목적으로 새로운 생약복합조성물인 HemoHIM을 개발하였다. 식품 원료로 사용 가능한 생약재 3종 당귀, 천궁, 백작약의 에탄올 분획을 열수추출물에 첨가하여 HemoHIM을 제조하였다. HemoHIM의 항알레르기 효과를 검증하기 위하여 사람 비만세포주 HMC-1을 사용해 compound 48/80으로 유도되는 히스타민 분비량과 PMA/A23187로 유도되는 염증성 사이토카인의 분비량을 측정하였다. 히스타민의 양은 형광분석법으로, 염증성 사이토카인 IL-6, IL-8, TNF-$\alpha$, GM-CSF의 양은 효소결합 면역측정법으로 측정하였다. 저농도의 HemoHIM에 의해 히스타민 분비량이 억제되었고, 모든 농도에서 IL-6, TNF-$\alpha$, GM-CSF의 분비량은 억제되었지만 IL-8은 고농도에서만 억제되었다. 사이토카인의 mRNA 발현량은 HemoHIM의 농도 의존적으로 억제되었다. 그리고 c-kit와 Fc$\varepsilon$RI의 mRNA 발현량도 모든 농도에서 억제되었지만, tryptase의 mRNA 발현량은 저 농도에서만 억제되었다. 이상의 결과로 HemoHIM이 비만세포의 활성을 억제하는 효과가 있다는 것을 알 수 있었으며, 상대적으로 독성이 적은 항알레르기 제재로 개발할 가능성을 제시한 것으로 생각된다.

Background : Although the pathophysiology of asthma has been reported, its mechanism has not been fully elucidated. The mast cell is an effector cells in allergic inflammation and secretes a number of chemokines. Chemokines are important for the recruitment of leukocytes to sites of infection, which is essential in host defense. Chemokines also contribute to the pathogenesis of several disorders such as asthma, chronic bronchitis, atopic dermatitis, allergic rhinitis, and rheumatoid arthritis. Objective : In this study, the aim was to identify the effect of Baekryunchihyo-tang(白蓮治哮湯) on expression of chemokines. This was examined by RT-PCR using the human mast cell line (HMC-l) Materials and Methods : HMC-l cells were used, which is known to secrete and express chemokines. In order to investigate the protective effect of Baekryunchihyo-tang(白蓮治哮湯), HMC-l cells were incubated with pretreatment of Baekryunchihyo-tang(白蓮治哮湯) for 24 hrs. RT-PCR analyses of chemokine genes of cells pretreated with Baekryunchihyo-tang(白蓮治哮湯) showed that expressions of IL-8, $MIP-l{\beta}$, and RANTES genes in these cells were lower and $MIP-l{\alpha}$ showed a similar pattern compared to the calcium ionophore-treated group. In addition, cell cytotoxicity concentration measurements were performed by MTT assay method. Results : After stimulation with 1 uM calcium ionophore A23178 for 2 hrs, IL-8, major one of CXC chemokines, was highly expressed, and expression of $MIP-l{\beta}$ and RANTES (CC chemokines) increased, while expression of $MIP-l{\alpha}$ did not change. The cell cytotoxicity of Baekryunchihyo-tang(白蓮治哮湯) with treatments at various concentrations and times was not observed, respectively. Conclusion : This study suggests that Baekryunchihyo-tang(白蓮治哮湯) has dose-dependent effects on mRNA expression of IL-8(CXC chemokines), $MIP-l{\beta}$ and RANTES(CC chemokines) in human mast cellline(HMC-l). So these herbal medicines may inhibit the inflammatory process of asthma. Advanced studies are required to investigate the mechanism of inhibition by herbal medicine in the asthma model. This study provides basic data on the possibility of the clinical treatment of Baekryunchihyo-tang(白蓮治哮湯) for allergic disorders.

Background: Thymic stromal lymphopoietin (TSLP) acts as a master switch for inflammatory responses. Ginsenoside Rg3 (Rg3) which is an active ingredient of Panax ginseng Meyer (Araliaceae) is known to possess various therapeutic effects. However, a modulatory effect of Rg3 on TSLP expression in the inflammatory responses remains poorly understood. Methods: We investigated antiinflammatory effects of Rg3 on an in vitro model using HMC-1 cells stimulated by PMA plus calcium ionophore (PMACI), as well as an in vivo model using PMA-induced mouse ear edema. TSLP and vascular endothelial growth factor (VEGF) levels were detected using enzyme-linked immunosorbent assay or real-time PCR analysis. Murine double minute 2 (MDM2) and hypoxia-inducible factor 1α (HIF1α) expression levels were detected using Western blot analysis. Results: Rg3 treatment restrained the production and mRNA expression levels of TSLP and VEGF in activated HMC-1 cells. Rg3 down-regulated the MDM2 expression level increased by PMACI stimulation. The HIF1α expression level was also reduced by Rg3 in activated HMC-1 cells. In addition, Rg3-administered mice showed the decreased redness and ear thickness in PMA-irritated ear edema. Rg3 inhibited the TSLP and VEGF levels in the serum and ear tissue homogenate. Moreover, the MDM2 and HIF1α expression levels in the ear tissue homogenate were suppressed by Rg3. Conclusion: Taken together, the current study identifies new mechanistic evidence about MDM2/HIF1α pathway in the antiinflammatory effect of Rg3, providing a new effective therapeutic strategy for the treatment of skin inflammatory diseases.

Hijikia fusiforme (HF), a member of brown algae family, exerts various pharmacological effects, including preventing arteriosclerosis and menopausal disorders. This study aimed to elucidate the ameliorative effect of HF on skin inflammation. We investigated the antioxidant and anti-inflammatory effect of HF extract to evaluate its potential as a functional materials. The antioxidant activity of HF was determined using 2,2-diphenyl-1-picrylhydrazy (DPPH) scavenging and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS+) scavenging. To determine the pharmacological mechanism of HF in inflammatory reaction, we evaluated the effects of HF on interleukin (IL)-8, IL-6 and tumor necrosis factor (TNF)-α production and nuclear factor-κB (NF-κB) activation in activated- human mast cells (HMC)-1. Results showed that HF had the high DPPH and ABTS+ radical scavenging activity, and it suppressed IL-8, IL-6 and TNF-α production in a concentration-dependent manner. Moreover, HF significantly ameliorated NF-kB activation in activated-HMC-1. Hence, these results provide evidence that HF's potential for skin inflammation therapy.

The prevalence of allergic disease has been increasing over the past few decades in the majority of Western industrialized nations. There are some socioeconomic disparities regarding allergic disease status and management. Pyeongwee-San (KMP6) is Korean medicine for the treatment of gastrointestinal tract disease. It is known that KMP6 has an improving effect on the spleen and stomach functions in traditional Korean medical theory. Here, we hypothesized that KMP6 could be used to regulate the inflammatory reaction. We show the molecular mechanisms of Pyeongwee-San (KMP6) on inflammatory reactions. A molecular docking simulation showed that hesperidin, component of KMP6, regulate the enzymatic activity by interaction in the active site of caspase-1. KMP6 control the activity of caspase-1 in activated human mast cell line (HMC-1 cells). KMP6 reduced the expression of receptor interacting protein (RIP)-2 in HMC-1 cells. Thymic stromal lymphopoietin protein production and mRNA expression were inhibited by KMP6. In the activated HMC-1 cells, KMP6 suppressed the activation of mitogen-ativated protein kinase and nuclear factor-kappaB. In addition, KMP6 significantly inhibited the expression of inflammatory cytokines. Our findings indicate that KMP6 may attenuate allergic reactions via the regulation of caspase-1/RIP-2 signaling pathway. These studies will help advance the social welfare system.

Mast cells are a potent source of mediators that regulate the inflammatory response in allergic reaction. To evaluate the atopic allergic effect of Asiasari radix(AR), the author investigated a possible effect of AR on mast cell-mediated allergic reaction, cytokines secretion and mRNA expression in vivo and in vitro. In mice orally administered by AR (0.01, 0.1 and 1.0 g/kg) for 1 h, compound 48/80-induced ear swelling was significantly reduced (P < 0.05). AR had inhibitory effects on tumor necrosis factor $(TNF)-{\alpha}$, interleukin (IL)-8, and IL-6 secretion from HMC-1. Significant reduced levels of $TNF-{\alpha}$ mRNA was observed in the human mast cell line (HMC-1) with AR (1.0 mg/ml). In addition, AR had no cytotoxic effect on cell viability. These results suggest that AR contributes to the treatment of atopic allergic reactions, and that its action may be due to inhibition of cytokine secretion and mRNA expression in HMC-1.

This research was performed in order to investigate the anti-inflammatory effects of Bupleuri Radix(BR) on the Immune response in vitro. Cellular proliferation and cytokine production were measured in mast cells or mouse B cells or CD4 Th cells. BR water extract inhibited the secretions of TNF-$\alpha$ and IL-6 in PMA/A23187 stimulated HMC-1 cells. It increased proliferation but did not affect the expressions of CD69 or CD23 in rIL-4/anti-CD40 activated S cells. BR reduced surface IgE expression and secreted IgE but increased the production of IL-4, IFN-$\gamma$ and IgG1 in the same cells. BR caused an increase in proliferation in anti-CD3/anti-CD28 stimulated CD4 Th cells but it did not affect the differentiation of Th1 or Th2 cells. However, IL-2 was increased in BR treated Th2 cells. Considering the above-mentioned results, BR can be applied to a broad range of anti-inflammatory reactions, but our data suggest that it will not be likely to exert any effects on type 1 allergic response.
