Seungmagalgeuntang-gamibang has long been known to have anti-allergic effect. However, the mechanism of action of Seungmagalgeuntang-gamibang is not well investigated. The author analysed the effects of Seungmagalgeuntang-gamibang on the vascular permeability, delayed-type and contact hypersensitivities, and phagocytic function, the results obtained are as follows: 1. Administration of Seungmagalgeungtang-gamibang decreased the vascular permeability induced by serotonin in the mouse. 2. Administration of Seungmagalgeuntang-gamibang decreased the vascular permeability induced by histamine without statistical significant. 3. Administration of Seungmagalgeuntang-gamibang decreased the delayed-type hypersensitivity induced by sheep red blood cells. 4. Administration of Seungmagalgeungtang-gamibang decreased the contact hypersensitivity induced by dinitrochlorobenzene. 5. Seungmagalgeungtang-gamibang increased the phagocytic-activities of macrophages in vitro and in vivo. 6. Seungmagalgeungtang-gamibang enhanced the formation of reactive oxygen intermediates in vitro and in vivo. The above results demonstrate that Seungmagalgeuntang-gamibang suppresses the hypersensitivity reactions with increasing the phagocytic functions and formations of reactive oxygen intermediates from macrophages.

Objectives In the theory of Korean medicine, rice straw (RS) has been used effectively as treatments for dyspepsia, diarrhea, enteritis, inflammatory epigastric diseases and various dermatitis. However, the theory has not been studied intensively yet about anti-inflammatory effects for human. This study was to investigate effects of RS for a treatment of allergic contact dermatitis (ACD) induced by 2,4-dinitrochlorobezene (DNCB) in mice. Methods In this experiment, effects of RS were investigated on changes in body weights, dorsum skin thickness, clinical aspects on the dorsum skin, spleen and body weight among these four groups; normal group (NOR), control group (CON), RS spread group (RSS) and RS spread and administer group (RSS+Adm). In addition, the effects on proliferations of splenocytes were also investigated in vitro and in vivo study. Results RSS group and RSS+Adm group showed increasing in body weights, diminished dorsum skin thickness and treated dermatitis on dorsum skin. In RSS+Adm group, spleen weights were lowered significantly compared to CON group. Conclusions In conclusion, these data suggest that RS can decrease symptoms of ACD significantly, and it shows the anti-inflammatory and immunosuppressant effect as well. Therefore, RS can be useful to treat patients with ACD.

The purpose of this research was to investigate the effects of Kamihyungbangjihwang-tang (KHT) on immediate-type allergic reaction. KHT was composed of hyungbangjihwangtang (HJT) and Rubus coreanus Miquel (RC) and Aspalathus linear is (AL). KHT and HJT (500 mg/kg) inhibited the systemic anaphylaxis induced by compound 48/80 and inhibited the passive cutaneous anaphylaxis (PCA) induced by anti-dinitrophenyl (DNP)-IgE and DNP-human serum albumin (HSA) in vivo. In addition, KHT, HJT, RC and AL inhibited the release of histamine and increased the release of cAMP from rat peritoneal mast cells. The anti-allergic action of KHT was more potent than those of HJT. These results indicate that KHT may be useful for the prevention and treatment of type I allergy related disease via inhibition of histamine release from mast cells.

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.

Objectives : The aim of this study was to investigate the effect for allergic-inflammation of Fritillariae Thunbergii Bulbus (FTB) on HaCaT cells and RBL2H3 cells. Methods : To investigate the effects of FTB for anti-inflammation in HaCaT cells, the cells were pretreated with FTB for 1h and then stimulated with $TNF-{\alpha}/IFN-{\beta}$ for 24h. Then thymus and activation-regulated chemokine (TARC) and Macrophage-derived chemokine (MDC) levels were analyzed with ELISA kit. Also to investigate the effect of skin barrier protein, the cells were treated with FTB of various concentrations, and then cells were harvested, expressions of skin barrier protein were measured with RT-PCR. To investigate the effects of FTB for anti-allergy in RBL2H3 cells, the cells were pre-treated with FTB for 1h, and then stimulated with A23187 for 30 min. ${\beta}$-hexosaminidase, IL-4 and $TNF-{\alpha}$ were measured using cultured media. The cells were harvested to analyze the mechanism of the effect for FTB via Western blot. Results : FTB did not show cytotoxicity in HaCaT and RBL2H3. In HaCaT cells, FTB significantly suppressed the expression of TARC, MDC at a dose-dependent manner and markedly increased formation of the skin barrier proteins. In RBL2H3 cells, FTB decreased release of the ${\beta}$-hexosaminidase, IL-4 and $TNF-{\alpha}$ in RBL2H3 through inhibition of the phosphorylation of JNK and p38, which are include in the signaling mechanism of MAPK Conclusion : These results indicate that FTB has an anti-inflammatory effect on the allergic response through blocking MAPK pathway. This suggest that FTB could be a therapeutic agent for allergic response.

유기농 및 일반재배 대두를 다양한 용매에서 추출하여 그 추출물에 대한 항산화 효과, 항염증 효과, 대식세포의 세포사멸 보호 효과, 그리고 알레르기 저해효과를 비교하였다. DPPH 법과 SOD 효소의 활성 측정으로 항산화 능력을 평가하였으며, 항염증 효과는 LPS로 유도시킨 Raw 264.7 세포주에서 염증 매개 단백질인 Cox-2와 iNOS의 발현량을 western blotting으로 조사하여 분석하였다. 또한 대식세포 보호 효과를 세포사멸 조절 단백질인 Bcl-xl의 발현량 조사로 평가하였고, 1 mM $H_2O_2$ 처리로 유도되는 세포사멸의 보호효과를 세포 수 측정법으로 조사하였다. 항알레르기 효과는 흰쥐의 비만세포인 RBL-2H3 세포주를 사용하여 IgE로 매개되는 비만세포의 탈과립화를 OPT assay로 측정하여 분석하였다. 그 결과, 일반 재배보다 유기 재배 대두 추출물이 더 좋은 항산화, 세포사멸 보호, 항염증 효과를 나타내었다. 특히 유기농 대두의 열수 추출물은 LPS로 유도시킨 염증반응을 효과적으로 억제하는 것으로 나타났다. 그러나 항알레르기 효과는 모든 추출물에서 히스타민 유리량이 약간 감소하는 것으로 나타나 유기농과 일반재배의 차이를 확인할 수 없었다. 대두에는 많은 유용한 생리활성물질 뿐 만 아니라 알레르기 유발 물질도 존재하는 것으로 알려져 있지만 조추출물 상태에서는 특이적인 알레르기 유발보다 오히려 항알레르기 효과가 나타났다. 결론적으로, 만성 염증 및 천식, 그리고 아토피피부염과 같은 염증관련 질환에는 유기재배된 대두가 일반 대두보다 좋은 억제 효과를 가지고 있다고 판단된다.

The purpose of this study was to investigate the efficacy of Torreyae semen extract against antimicrobial and allergic contact dermatitis to explore its utility as a herbal resource. To this end, the antibacterial effects of Torreyae Semend extracted with hot water and ethanol (30%, 60%, 90%) were investigated using Staphylococcus aureus, Staphylococcus epidermidis, pseudomonas aeruginosa, and Propionibacterium acnes. And observed the anti-atopic dermatitis efficacy with a mouse model that allergic contact dermatitis induced by DNCB. Experimental results showed that the antibacterial activity against S. epidermidis and P. aeruginosa was significantly higher in the hot water extract of Torreyae Semen. We observed that the extracts of 30% ethanol and hot water of Torreyae Semen inhibited growth in a concentration-dependent manner in P. acnes & S. epidermidis. We observed that the administration of hot water extracts and 30% ethanol extract of Torreyae Semen significantly reduce the thickness of ear & back and gross skin condition compared to the control group in the mice with allergic contact dermatitis. As a result of H & E histological staining, it was observed that the Torreyae Semen extraction group had markedly reduced epidermis and skin thickness, granules, and keratinization compared to the control group. The groups administrated with Torreyae Semen hot water extracts had decreased TNF-α and IL-10 contents compared with the control group. As a result, Torreyae Semen may be used as a useful herbal resource because it has a certain level of antibacterial and anti-atopic effects.

Activated T helper 2 (Th2) immune function is hallmark of various allergic diseases. We investigated the anti-allergic effect of Jagamcho-tang extract(JE) on ovalbumin(OVA)-induced atopic dermatitis mice model and OVA-stimulated splenocytes isolated from the mice. Mice were intraperitoneally injected OVA/alum solution 2 times at interval of 14 days, followed by oral administration of JE for 7 days. After administration, mice were subcutaneously injected with OVA in ear. JE treatment reduced ear swelling and infiltration of inflammatory cells in ear. Serum levels of interleukin(IL)-4 and immunoglobulins, such as total-IgE and OVA-specific IgE, were decreased in JE treated group. Furthermore, JE treatment decreased OVA-induced Th2-associated cytokines like IL-4, IL-5 and IL-13 mRNA levels in splenocytes. In conclusion, JE reduced allergic immune response via IgE production and Th2 response in OVA-sensitized mice, suggesting that JE could be useful prescription for allergic diseases including atopic dermatitis.

Objectives Perillae Folium (PF) has been widely used in Korean herbal medicines used for treatment of acute and chronic inflammatory diseases, such as rhinitis, asthma, and enteritis. In this study, to investigate the protective effect of PF on type 1 allergic response, we determined whether PF inhibits early or late allergic responses. Methods The effect of PF was analyzed by ELISA,. RT-PCR and Western blot in RBL-2H3 cells. Levels of ${\beta}$-hexosaminidase, interleukin (IL)-4 and TNF-${\alpha}$ were measured using enzyme-linked immunosorbent assays (ELISAs). mRNA levels of cytokines and enzymes were analyzed with RT-PCR. Signal transduction was analyzed with Western blot. Results We found that PF suppressed ${\beta}$-hexosaminidase release in RBL-2H3 by the IgE-DNP-HSA stimulation. PF also significantly inhibited enzymes level, such as COX-1, COX-2, iNOS, and HDC2, along with reduced cytokine levels, such as IL-2, IL-3, IL-4, IL-6, IL-13, and TNF-${\alpha}$ in RBL-2H3. In addition, PF suppressed the phospholyation of ERK1/2, JNK1/2, and $I{\kappa}B{\alpha}$. Conclusions Our results indicate that PF protects against type 1 allergic response and exert an anti-inflammatory effect through the inhibition of degranulation and expression of cytokines and enzymes via the suppression of signal transduction.
