Anemarrhenae Rhizoma (AR) is used in traditional oriental medicine for various medicinal purposes. However, the exact mechanism that accounts for the anti-allergy and anti-inflammatory effects of the AR is still not fully understood. The aim of The present study is to elucidate whether and how AR modulates the allergic reactions in vivo, and inflammatory reaction in vitro. In this study, we showed that AR significantly decreased compound 48/80-induced systemic anaphylaxis, paw oedema, and histamine release from preparation of rat peritoneal mast cells. Also, AR inhibited the expression of inflammatory cytokine in PMA plus A23187-stimulated human mast cells (HMC-1). In addition, we showed that anti-inflammatory mechanism of AR is through suppression of nuclear factor-${\kappa}B$ activation $I{\kappa}B-{\alpha}$degradation. These results provided new insight into the pharmacological actions of AR as a potential molecule for therapy of inflammatory allergic diseases.

Asian sand dust is known to promote various respiratory symptoms or disorders. For the prevention of harmful health effects by Asian sand dust, the best strategy is known to avoid or reduce exposure to the Asian sand dust. Several studies have shown that Korean red ginseng (RG) has anti-inflammatory and anti-allergic effects. The study aimed to clarify the effect of Korean red ginseng intake on lung inflammation responses to artificial sand dust (ASD) similar to Asian sand dust. BALB/c mice were divided into five groups (n=12) of control (saline), ovalbumin (OVA), OVA with ASD, OVA plus RG with ASD, and OVA plus dexamethasone (DEXA) with ASD. Histopathologic evaluation of lung was conducted. Interleukin (IL)-5, IL-12, interferon (IFN)-${\gamma}$, IL-13, monocyte chemotactic protein (MCP)-1, and eotaxin within bronchoalveolar lavage (BAL) fluid were measured by ELISA. OVA+ASD group significantly increased concentrations of IL-5, IL-13, MCP-1, and eotaxin (P<0.01) compared to the control. OVA+ASD+RG group showed significant decreased levels of IL-2, IL-13, MCP-1 and eotaxin (P<0.01) compared with OVA+ASD. Between RG and DEXA treatment groups, there was no significant difference in all cytokines and chemokines. The inflammatory cells were significantly decreased in treatment groups with RG or DEXA compared to OVA+ASD group. This study suggests a beneficial effect of Korean RG administration in preventing inflammation of lung resulting from Asian sand dust.

Background and Objective : Asthma is a chronic inflammatory disease at the mucosa and is associated with excess production of Th2 cytokine and eosinophil accumulation in lung.Gamchomahwang-tangextract(GME) is one of the well known prescription used in oriental medicine for treating asthma. This study was designed to compare the anti-asthmatic effect of GME according to the ratio of 2 compounds.Methods : To examine the effects of GME on asthma, mice were sensitized with 100 ㎍ of OVA and 1 ㎎ of aluminum potassium sulfate(Alum; Sigma) intraperitoneally on day 1 and 15. From day 22, mice were challenged on 3 consecutive days with 5% OVA. The anti-asthmatic effects of GME were evaluated by enhanced pause(Penh), bronchoalveolar lavage fluids (BALF), inflammatory cytokine production and genes expression, serum IgE production. and histological change in lung tissue. GMEⅠ consists of ES and GU in the proportion 2:1(300 ㎎/㎏ group), GMEⅡ consist of ES and GU in the proprtion 4:1(300 ㎎/㎏ group).Results : GMEⅠ,Ⅱ generally inhibited lung inflammation, inflammatory cells infiltration and cytokine production and gene expression such as IL-4, IL-5 and IL-13 in BALF and serum IgE level. GMEⅡ significantly reduced the cytokine production and gene expression such as IL-4, IL-5 and IL-13 in BALF and GMEⅠ decreased cytokine production of IL-4, IL-13 in BALF and gene expression of IL-4, IL-5 in Lung. GMEⅡ potently inhibited the development of Penh and also reduced the number of eosinophil during OVA-induced AHR(airway hyper-reactivity). Overall the results show that GMEⅡ has more effect on inhibiting production, gene expression of cytokine, serum IgE level and development of Penh than GMEⅠ. Consequently, GMEⅡ might be more effective than GMEⅠ at inhibiting allergic asthma on the OVA-induced mice model.Conclusion : These results indicate that GME has a deep inhibitory effects on airway inflammation and hyperresponsiveness in mice model of asthma and that suppression of IL-4, IL-5, IL-13 expression and decrease of IL-4, IL-5, IL-13 production in BALF might contribute this effect. Hence, the results indicate that GME might be useful herbal medicine of allergic asthma. As a result, GMEⅡ mght be superior to GMEⅠ in the aspect of anti-asthmatic effect on the OVA-induced mice model.

Objective : Glycyrrhiza uralensis Fisch (GUF) has been used as remedy of allergic diseases for a long time in Korea. In the present study, we investigated the anti-allergic effects of GUF on experimental allergic asthma mouse model using ovalbumin (OVA). Methods : BALB/c mice were sensitized and challenged with 100 ug of OVA and 1 mg of aluminum potassium sulfate of 0.2 ml phosphate-buffered saline (PBS) intraperitoneally on day 1 and 15. Mice were challenged on 3 consecutive days with 5% OVA and AHR was assessed 24 hrs after the last challenge. We examined total inflammatory cell number in bronchoaveloar lavage fluid (BALF), Th2-associated cytokine productions and lung histology. Results : GUF potently inhibited the development of airway hypersensitivity and also reduced the number of BAL cells during OVA-induced allergic asthma. GUF also inhibited cytokine productions such as IL-4, IL-13 in lung tissue. Furthermore, GUF treatment inhibited allergic airway inflammation. Conclusion : These results suggest that GUF may inhibit the production of IL-4, IL-13 and infiltration of inflammatory cell and be beneficial oriental medicine for allergic asthma.

Allergic rhinitis is an inflammation of the nasal mucosa which is triggered by an allergic reaction. When exposed to certain allergens, the IgE covered mast cells degranulate releasing inflammatory mediators and cytokines which results in a local inflammatory reaction. In many recent studies, molecular biological methods have been used to investigate the role of cytokines in pathogenesis and new therapeutic targets of allergic rhinitis. This experimental study was done to research effects of Sochungryong-tang. We have studied effect of mice on OVA-induced production of IL-4, IL-5, IFN-${\gamma}$ by murine splenocytes and effect of OVA-induced total IgE and OVA-specific IgE. The results were as follows; 1. In IL-4 study, Sochungryong-tang treated group was proved significant inhibitory effect(p〈0.005). 2. In IL-5 study, Sochungryong-tang treated group was proved significant inhibitory effect(p〈0.05). 3. In JFN-${\gamma}$ study, Sochungryong-tang treated group was proved significant inhibitory effect(p〈0.000001). 4. In Total IgE, Sochungryong-tang treated group was proved significant inhibitory effect(p〈0.000001). 5. In OVA-specific IgE, Sochungryong-tang treated group didn't showed significant inhibitory effect. Depending upon above results, it is considered that Sochungryong-tang has the inhibitory effect on the allergic rhinitis of mice and suggested that it could be used in relieving patients of the symptoms which are caused by allergic rhinitis.

The worldwide prevalence and severity of allergic diseases including atopic and contact dermatitis has increased dramatically over the past decade, especially in developed countries. Mast cells are important effector cells in allergic reactions. The purpose of this study was undertaken to investigate the anti-allergic and anti-pruritic effects of Diospyros lotus leaf extract (DLE). DLE was prepared by extracting with distilled water. In the present study, we investigated the effect of DLE on the production of tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), interleukin-$1{\beta}$ (IL-$1{\alpha}$) and histamine in rat peritoneal mast cells (RPMCs), and on the skin lesion, leukocyte infiltration and scratching behavior in mice. Phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore A23187 significantly increased TNF-${\alpha}$ and IL-$1{\beta}$ production compared with media control. However, TNF-${\alpha}$ and IL-6 production increased by PMA plus A23187 treatment were significantly inhibited by DLE in a dose-dependent manner. DLE also inhibited the histamine release from RPMCs stimulated by compound 48/80, which promotes histamine release. Moreover, DLE administration had an inhibitory effects on the scratching behavior induced by pruritogen (compound 48/80, histamine) in ICR mice. Furthermore, DLE inhibited the skin lesions, inflammatory and mast cells in hairless mice sensitized by 2,4-dinitrofluorobenzene (DNFB). DLE administration reduced the IL-4 and IgE production induced by DNFB sensitization in hairless mice. These results suggest that DLE has a potential use as a herb medicine for treatment against allergy and pruritus-related disease.

Method : While macrophage 264.7cells was chosen as a normal group a control group was classified into three groups. One was stimulated with LPS. and another was pretreated with Woobangja for 1 hour. The third was pretreated with gydrocortisone for 1 hour. After the pretreatment, macrophage were incubated with lipopolysaccharide(LPS) 100 ng/ml for 12h and media collected and $TNF-{\alpha}$, IL-6, $IL-1{\beta}$, IL-10 concentration in supernatants were measured each by Enzyme linked immuno-sorbent assay. Woobangja were used $50\;{\mu}g/ml$, $100\;{\mu}g/ml$, $250\;{\mu}g/ml$, $500\;{\mu}g/ml$, 1 mg/ml. Hydrocortisones were used respectively $10^{-8}\;M$,$10^{-7}\;M$,$10^{-6}\;M$,$10^{-5}\;M$,$10^{-4}\;M$. Results : Woobangja showed inhibitory effect on $TNF-{\alpha}$ by LPS-stimulated macrophage 264.7. The inhibitory effect was most significant in 1mg/ml(p<0.01), and has increased according to the number of doses. Woobangja also showed inhibitory effect on IL-10 by LPS-stimulated macrophasg 264.7. The inhibitory effect was most significant in $100\;{\mu}g/ml$, and was not in a dose-dependent manner as Hydrocortisone group. Woobangja and Hydrocortison showed contrary effect on $IL-1{\beta}$ in al five concentration(p<0.01), and at the lowest concentration ($50\;{\mu}g/ml$) the level of $IL-1{\beta}$ was the lowest. On the other hand hydrocortison was observed to have inhibitory effect on $IL-1{\beta}$ in all five concentration(p<0.01). IL-6 was inhibited by hydrocortison in a roughly dose-dependent manner, but was not inhibited by Woobangja. On the contrary Woobangja obviously increased the expression of $IL-1{\beta}$ in all five concentration(p<0.01), but it was not related with concentrations. Conclusion : 1. Woobangja does significantly inhibit the expression of $TNF-{\alpha}$ by LPS-stimulated macrophage 264.7. 2. Woobangja does significantly increse the expression of IL-6 by LPS-stimulated macrophage 264.7. 3. Woobangja does significantly increse the expression of $IL-1{\beta}$ by LPS-stimulated macrophage 264.7. 4. Woobangja does significantly inhibit the expression of IL-10 by LPS-stimulated macrophage 264.7. 5. Woobangja is observer to have anti-allergic inflammatory effect through inhibiting inflammatory cytokine.

Objective: This experimental study was performed to examine the in vitro and in viva anti-inflammatory and anti-allergic effects of Mori Cortex. Methods: Water extract of Mori Cortex was studied to its ability to stimulate or inhibit macrophage 264.7 cells to produce inflammatory and allergic mediators. Cytokines such as $IL-1{\beta}$, IL-6, IL-10 and $TNF-{\alpha}$ were measured by immunochemical assay. In vitro, the macrophages 264.7 were classified into four groups. One group was a normal group. The other group was a (-) control group stimulated with LPS. And the third group was a (+) control group pretreated for 1 hour with hydrocortisone. And the fourth group was a sample group pretreated for 1 hour with Mori Cortex. After pretreatment, macrophage were incubated with lipopolysaccharide(LPS) $100\;ng/m{\ell}$ for 12 hour and media collected and $IL-1{\beta}$, IL-6, IL-10 and $TNF-{\alpha}$ concentrations in supernatants were measured each by Enzyme linked immuno-soubent assay. Mori Cortex were used $50\;{\mu}g/m{\ell},\;100\;{\mu}g/m{\ell},\;250\;{\mu}g/m{\ell},\;500\;{\mu}g/m{\ell},\;and\;1,000\;{\mu}g/m{\ell}$. Hydrocortisones were used $10^{-8}M,\;10^{-7}M,\;10^{-6}M,\;10^{-5}M\;and\;10^{-4}M$. In vivo, the SD rats were classified into three groups. One group was a normal group injected with normal saline into the abdominal cavity. The other was a control group prescribed to compound 48/80 after normal saline injection. And the third was a sample group prescribed to compound 40/80 after Mori Cortex injection. Then, the release of histamine, IL-6 and $TNF-{\alpha}$ were measured. Results : In vitro, Man Cortex significantly increased the release of $IL-1{\beta}\;and\;TNF-{\alpha}$ by LPS-stimulated macrophage 264.7 cells. And it significantly decreased the release of IL-10. In IL-6, Mori Cortex of low concentration significantly decreased the release of IL-6, but that of high concentration acted in reverse. In vivo, Man Cortex didn't show significant inhibitory effects on the release of histamine and IL-6 in comparison with that of the control group. But it significantly increased the release of $TNF-{\alpha}$ in comparison with that of the control group.

Atopic dermatitis is a recurrent or chronic eczematous skin disease with severe pruritus and has annually increased in Korea. In this study, we investigated whether Duchesnea chrysantha (Dc) extracts have an anti-inflammatory effect in human monocytic THP-1 cells and human eosinophilic EoL-1 cells. The dried and powdered whole plants of Dc were extracted with 80% EtOH (Dc-1). The residue was diluted with water, and then successively partitioned with n-hexane, EtOAc, and BuOH to produce the n-hexane (Dc-2), EtOAc (Dc-3), BuOH (Dc-4), and the water-soluble fractions (Dc-5), respectively. The mite extract and LPS increased the production of IL-6, IL-8 and MCP-1 in THP-1 cells and the increase was strongly suppressed by Dc-3 extract, as compare with other extracts. Dc-3 also inhibited the release of IL-6 increased by mite extract and LPS in EoL-1 cells. However, Dc-3 extract increased IL-8 production induced by the mite extract and LPS in EoL-1 cells. These results suggest that Dc extract may be used as anti-inflammatory agents in treating allergic disorders such as asthma and atopic dermatitis.
