Sophorae Radix (SFR) is known as a therapeutic drug that has been used in Oriental traditional medicine for the treatment of skin and mucosal ulcers, gastrointestinal hemorrhage, diarrhea, inflammation and arrhythmia. In the present study, we examined the effects of the aqueous extract of SFR on anti-inflammation, anti-allergic and anti-oxidant effect in various cell lines; they include mouse lung fibroblast cells (hFCs), human mast cells (HMC-1), human monocytic cells (THP-1), and RAW 264.7 cells. Treatment with SFR extract at a concentration of 250 ${\mu}g$/ml for 24h showed no significant decrease in the survival rate of the hFCs. SFR decreased the mRNA expression of IL-8, TNF-$\alpha$, and IL-6 in HMC-1 cells. SFR extract treatment significantly inhi-bited the protein expression of IL-6 and, IL-8 induced by mite in THP-1 cells and it also did MCP-1 expression. We examined the alternation of histamine release in HMC-1 cells for investigating anti-allergic effect of SFR. Histamine secretion decreased after the treatment with SFR. In addition, SFR extract treatment at a concentration of 10 ${\mu}g$/ml, 100 ${\mu}g$ /ml, and 200 ${\mu}g$/ml lowered the $\beta$-hexosaminidase to 10.3%, 21.7%, and 50.8%, respectively. IC50 of SFR extract in RBL-2H3 cells was 196.85 ${\mu}g$/ml. Both activity of NF-$\kappa$B promoter in RBL-2H3 cells significantly diminished after the dose-dependent treatment of SFR. Therefore, our results indicate that SFR has anti-inflammatory and it may be useful for treating allergic diseases such as atopic dermatitis.

Electroacupuncture(EA) is commonly used in various diseases. In the present study, the effect of EA in the allergic mouse model was examined. Allergy is generated via immunological mechanism and non-immunological mechanism. Mast cells activated dy those mechanisms get to release various substances such as histamine, leukotrienes, prostaglandin, TNF-$\alpha$, IL-4, IL-6, etc. which induce allergic reactions and the following inflammatory responses. To evaluate the anti-allergic effects of EA, mortality, ear swelling response, vascular permeability and cytokine secretion were investigated in EA group and non-EA group of which mice were compound 48/80-induced allergy model or PCA model. Compound 48/80 induces allergic reaction via non-immunological mechanism and PCA model is generated through the same mechanism with immediate-type(Type1) allergic reaction, one of immunological allergic reactions. EA inhibited compound 48/80-induced ear swelling response but did not inhibit the systemic anaphylaxis. EA also inhibited passive cutaneous anaphylaxis(PCA) activated dy anti-dinitrophenol IgE. In addition, EA inhibited IL-6 and TNF-$\alpha$ secretion from 48 h PCA in mice. These results indicate that EA may be used for the treatment of mast cell-mediated allergic diseases, especially immediate-type(Type 1) allergy and non-immunologically mediated allergy.

The discovery of drugs on the treatment of rhinitis and allergic disease is a very important subject in human heath. The Shinbijen has been used for centruries as a traditional medicine in Korea and is known to have an anti-inflammatory effect. However, its specific mechanism of action is still unknown. In this report, we investigated the effect of hot water extract from Shinbijen on OVA-mediated allergic reaction and studied its possible mechanism of action using fluorescenc microscopy and RT-PCR analysis. Shinbijen inhibited OVA-induced rhinitis, total cells in BFA and lymphocyte related to inflammation in mice. Shinbijen decreased immuno response, which activated by IL-4, COX-2 and iNOS expression. in tissue. Shinbijen reduced inflammatory molecule release from mice lung tissue and CD4/CD8 cells activated by cardiac blood. Shinbijen decreased OVA-induced IL-4 and iNOS levels in pulmonary alveoli. Our findings provide evidence that Shinbijen inhibits OVA-induced allergic reactions, and also demonstrate the involvement of inflammation and allergic disease in these effects.

Malus sieboldii is a dicotyledonous plant that grows widely in Jeju Island and Ganghwa Island in Korea. Malus sieboldii has been known as a detoxifying and antioxidant plant, but study on allergic diseases is not known. In this study, we investigated the effect of Malus sieboldii extract (MSE) on the activation of mast cells, which is well known to be a critical causative cell to induce allergic diseases. As a result of our experiments, MSE inhibited the degranulation and inflammatory cytokine secretion from mast cells by antigen stimulation. As the mechanism of MSE in mast cells, it inhibited the activation of Syk kinase, a essential signaling protein activated by antigen, and further inhibited activation of $PLC{\gamma}$ and MAP kinase(P38, ERK1/2, and JNK). Furthermore, in vivo animal studies showed that MSE significantly inhibited IgE-mediated passive cutaneous anaphylaxis and passive systemic anaphylaxis in a dose-dependent manner. Taken together, the results of this study showed for the first time that MSE inhibited IgE-mediated allergic responses by suppressing Syk kinase in mast cells. Therefore, it could be considered that MSE is worth developing as an anti-allergic material.

4-Hydroxy-2-(4-hydroxyphenethyl)isoindoline-1,3-dione (PD1) is a synthetic phthalimide derivative of a marine compound. PD1 has peroxisome proliferator-activated receptor (PPAR) ${\gamma}$ agonistic and anti-inflammatory effects. This study aimed to investigate the effect of PD1 on allergic asthma using rat basophilic leukemia (RBL)-2H3 mast cells and an ovalbumin (OVA)-induced asthma mouse model. In vitro, PD1 suppressed ${\beta}$-hexosaminidase activity in RBL-2H3 cells. In the OVA-induced allergic asthma mouse model, increased inflammatory cells and elevated Th2 and Th1 cytokine levels were observed in bronchoalveolar lavage fluid (BALF) and lung tissue. PD1 administration decreased the numbers of inflammatory cells, especially eosinophils, and reduced the mRNA and protein levels of the Th2 cytokines including interleukin (IL)-4 and IL-13, in BALF and lung tissue. The severity of inflammation and mucin secretion in the lungs of PD1-treated mice was also less. These findings indicate that PD1 could be a potential compound for anti-allergic therapy.

Handayeolso-Tang(HDT) has been used as traditional medicine for the treatment of Taeumin TaeYang-Hanguel. The present study was conducted to investigate the anti-allergic activity of Handayeolso-Tang(HDT). We investigated the anti-allergic effects of HDT in RBL-2H3 basophilic leukemia cells by compound48/80, a mast cell degranulator and compound 48/80 induced anaphylactic shock in mice. HDT significantly inhibited ${\beta}-hexosaminidase$ and histamine release from compound 48/80 stimulated RBL-2H3 cells. In addition, HDT effectively inhibited anaphylactic shock in mice by 45% at a dose 120 mg/mouse versus PBS treated control after the I.p injection(8 mg/kg) of compound 48/80. The in vitro anti-inflammatory activities of HDT in LPS-stimulated RAW 264.7 cells were investigated. HDT inhibited NO production in LPS-stimulated RAW 264.7 cells and effectively dowregulated the expression of iNOS mRNA and iNOS protein expression in LPS -stimulated RAW 264.7 cells. These result provide evidences that HDT may be beneficial in the treatment of allergic inflammtory disease.

In this study, we investigate anti-allergic and anti-inflammatory effects of Leonurus sibiricus seed (LSS) extract in basophilic leukemia RBL-2H3 cells. To identify anti-allergic actions of LSS, the degranulation was evaluated in IgE and DNP-BSA stimulated RBL-2H3 cells. At the concentration of $100{\mu}g/ml$ of methanol (MeOH) extract and Methylene chloride (MC) and Ethyl acetate (EtOAc) fractions, the degranulation was significantly inhibited 16.7%, 16.7% and 27.9% respectively. And then, to assess anti-inflammatory effects of LSS, IL-4 and IL-13 mRNA level were detected in PMA/ionomycin (PI)-induced RBL-2H3 cells and cell proliferation and IL-4 mRNA level in isolated splenocytes from Balb/c mice. LSS MeOH extract and MC and EtOAc fractions significantly decreased the level of IL-4 and IL-13 mRNA in PI-induced RBL-2H3 cells and showed inhibitory effects on cell proliferation and expression of IL-4 mRNA level in mouse splenocytes. Taken together, these results suggest that LSS has potential anti-allergic and anti-inflammatory effects and EtOAc fraction is the most effective in regulating immune responses.

Schizandrin (SZ), was isolated from the fruit of Schizandra chinensis, has been reported to have many biological properties, including anti-inflammatory and antitumor activities. However, its anti-allergic effects are not completely elucidated. We focused on the anti-allergic effects of SZ in PMA/ionomycin (PI)-induced rat basophilic leukemia (RBL-2H3) cells and P815 mast cells. Cytokines (IL-4, IL-13), synthesized by basophils and mast cells, are implicated in pathological conditions such as asthma and allergy. The production of IL-4 and IL-13 was quantified by ELISA and the mRNA expression was detected by using RT-PCR assay. In this study, we found that SZ did not show cytotoxic effect at up to 100 ${\mu}M$ on RBL-2H3 cells and mast cells. In addition, SZ inhibited the production of IL-4 and IL-13 and also decreased the level of mRNA in PI-induced RBL-2H3 cells and mast cells in a dose-dependent manner. Thus, we suggest that SZ may have the effect on preventing allergic disorders by inhibiting IL-4 and IL-13 cytokines.

Objective : Allergic disease, a very common chronic illness that affects all ages of patients, has been well characterized as an IgE-dependent immunologic response. Recently, interest has grown about the late inflammatory reaction as well as the early one characterized by IgE and mast cells in allergic disease. The purpose of this study was to find the anti-inflammatory effect of Taeeumjowui-tang (Taiyintiaowei-tang) in allergic reaction. Methods : The experiment was performed using Raw 264.7 cells pretreated with Taeeumjowui-tang contents extracts. The results were measured for different concentrations of Taeeumjowui-tang extracts (100, 200, $300{\mu}g$/ml): the toxicity and proliferation of cells by MTT analysis, LPS-induced NO production using Griess reagent and IL-6/ TNF-${\alpha}$ production, which is a significant criteria for diagnosing allergic reaction. Results : No toxicity of Taeeumjowui-tang (100, 200, $300{\mu}g$/ml) on Raw 264.7 cells was found after 24 hours incubation. LPS-induced NO production was reduced after treatment with Taeeumjowui-tang (100, 200, $300{\mu}g$/ml)(P<0.001). IL-6 decreased only at $100{\mu}g$/ml(P<0.05). TNF-${\alpha}$ production decreased only at $300{\mu}g$/ml, but still statistically insignificant. There was no relationship between any components of Taeeumjowui-tang alone and inhibition of NO production. Conclusions : These data suggest that Taeeumjowui-tang has anti-inflammatory effects in allergic reaction.

Dansam, the root of Salvia miltiorrhiza BGE. (Labiatae), has a bitter and a slightly 'cold' property. and is nontoxic. It has been used for the treatment of diseases such as tumors, bruises, gynecologic diseases, menoxenia, anemia and so forth. As an oriental medicine pathway, anal therapy has many kinds of treatments, Retention enema is one the most useful, advantageous methods of anal therapy. This experiment was performed in order to study the effect of an aqueous extract of Salviae radix root(SRRAE) on Immediate type allergic reaction by Retention enema. The results were obtained as follows, 1. SRRAE inhibited compound 48/80-induced Immediate type allergic reaction 100% with the dose of 0.1g/kg by anal treatment. However, SRRAE showed no significant inhibitory effect on the same reaction by oral treatment. When mice were pretreated with SRRAE at a concentration ranging from 0.001 to 1.0g/kg, by intra-anal treatment, the serum histamine levels were reduced in a dose-dependent manner. 2. SRRAE also inhibited by 79.8% local cutaneous allergic reaction activated by anti-dinitrophenyl (DNP) IgE. 3. SRRAE close-dependently inhibited the histamine release from rat peritoneal mast cells(RPMC) by anti-DNP IgE., but SRRAE not inhibited compound 48/80-induced histamine release. 4. SRRAE dose-dependently inhibited tumor necrosis $factor-\;{\alpha}$ $(TNF-\;{\alpha}$) production from RPMC by anti-DNP IgE. Moreover, the level of cAMP in RPMC, when SRRAE was added, significantly increased compared with that of a normal control. According to the above results, anal therapy(Retention enema) of SRRAE may be beneficial in the treatment of systemic and local Immediate type allergic reactions.
