The rhizomes of Acorus gramineus have frequently been used in traditional medicine mainly for sedation as well as enhancing brain function. In this study, the anti-allergic activity of A. gramineus was investigated. The 70% ethanol extract of the rhizomes of A. gramineus was found to inhibit the allergic response against 5-lipoxygenase (5-LOX)-catalyzed leukotriene (LT) production from rat basophilic leukemia (RBL)-1 cells and ${\beta}$-hexosaminidase release from RBL-2H3 cells with $IC_{50}$'s of 48.9 and > $200{\mu}g/ml$, respectively. Among the 9 major constituents isolated, ${\beta}$-asarone, (2R,3R,4S,5S)-2,4-dimethyl-1,3-bis (2',4',5'-trimethoxyphenyl)tetrahydrofuran (AF) and 2,3-dihydro-4,5,7-trimethoxy-1-ethyl-2-methyl-3-(2,4,5-trimethoxyphenyl)indene (AI) strongly inhibited 5-LOX-catalyzed LT production in A23187-treated RBL-1 cells, AI being the most potent ($IC_{50}=6.7{\mu}M$). Against ${\beta}$-hexosaminidase release by antigen-stimulated RBL-2H3 cells, only AI exhibited strong inhibition ($IC_{50}=7.3{\mu}M$) while ${\beta}$-asarone and AF showed 26.0% and 39.9% inhibition at $50{\mu}M$, respectively. In addition, the ethanol extract of A. gramineus showed significant inhibitory action against the hapten-induced delayed hypersensitivity reaction in mice by oral administration at 200 mg/kg. Therefore, it is suggested that A. gramineus possesses anti-allergic activity and the constituents including ${\beta}$-asarone and AI certainly contribute to the anti-allergic activity of the rhizomes of A. gramineus.

Objectives : The root of Codonopsis pilosula (Fr.) Nannf. (Codonopsis Pilosulae Radix) has been traditionally used as a oriental medicine with an anti-thrombotic, antidiabetic, anticancer, and anti-gastric ulcer effects and immunological adjuvant. In this study, we investigated the effect of 70% ethanol extract of Codonopsis Pilosulae Radix (CPR-E) on ovalbumin (OVA)-induced allergic responses in mice. Methods : Mice were sensitized (1, 8, and 15 days) with OVA and airway challenged(22, 24, 26, 28, and 30 days) to induced allergic responses. CPR-E extract at doses of 50 and 100 mg/kg/body weight was orally administered from days 21 to 30 consecutively. The levels of allergic mediators such as histamine, OVA-specific immunoglobulin (Ig) E, and Th1/Th2 cytokines such as IFN-${\gamma}$ and IL-4 were measured in the sera of mice by ELISA. The histological change of lung tissue was observed by hematoxylin and eosin (H&E) staining. Results : CPR-E extract significantly decreased the serum levels of histamine, OVA-specific IgE, and IL-4 compared with those of OVA control group, but significantly increased the serum level of IFN-${\gamma}$. Based on H&E staining, CPR-E extract inhibited the infiltration of inflammatory cells into lung tissues with histological changes. Conclusions : These results indicate that CPR-E extract has anti-inflammatory and anti-allergic responses through regulating the cytokine balance, suggesting that the extract may be useful for the treatment of allergic inflammatory diseases such as bronchial asthma and allergic rhinitis.

Bee venom (BV), well known as a traditional Oriental medicine, has been widely used in the treatment of some immune-related diseases. However, the anti-allergic effect of BV have not been reported. In this study, we investigated the antiallergic effect of BV on triphasic cutaneous reaction (TpCR) and passive cutaneous anaphylaxis (PCA). Our results indicated that BV suppress ear swelling and vascular permeability on IgE mediated type I hypersensitivity response. Increase in ear thickness was significantly inhibited by BV in this model. BV also blocked the infiltration of immune cells into the ear. Moreover, BV suppressed expression of HDAC3, Tryptase, MCP-1 in ear tissue. These results demonstrated that BV has a suppressive effect on allergic reaction.

Rumex crispus is known to have anticancer, antioxidant, antibacterial, and bone loss inhibitory activities. Mast cells are critical immune cells that induce a type 1 IgE-mediated allergic reaction. However, there are no reports of inhibitory effects of Rumex crispus on mast cells and allergic reactions. In this study, we performed some experiments to investigate whether Rumex crispus ethanol extract(RCE) has any inhibitory effect on antigen-induced type I allergic response in vitro and in vivo. RCE inhibited degranulation of IgE-mediated mast cells(IC₅₀, ~57 ㎍/ml) and cytokine production such as TNF-α and IL-4 in a dose-dependent manner. In vivo, RCE significantly inhibited passive cutaneous anaphylaxis(PCA)(ED₅₀, ~198 mg/kg) in mice. Furthermore, RCE inhibited degranulation of MCs in ear tissue of mice with PCA. Mechanism studies showed that RCE inhibited the activation of Syk and Syk-dependent pathway such as LAT, PLC-γ, Akt, and MAP Kinase. Our results demonstrate for the first time that RCE inhibits type I hypersensitive response by suppressing the activity of Syk in mast cells, thereby reducing degranulation and cytokine production. Taken together, RCE could be used as a novel therapeutic material to suppress allergic diseases.

Mast cells are crucial as effector cells in the immediate-type allergic reaction. Lentinus edodes has been the popular edible mushroom in oriental countries and reported to have immunomodulatory, anti-tumor, anti-atherogenic, anti-viral, and anti-allergic activities. However, the roles of L. edodes in mast cell-mediated anaphylactic reaction have not been fully elucidated. In this research, we have demonstrated the effects of the methanol extract of L. edodes (MELE) on mast cell-mediated anaphylaxis-like and anaphylactic reactions. MELE suppressed systemic anaphylaxis-like reaction, plasma histamine levels, and ear swelling response in mice treated with compound 48/80. MELE also suppressed passive systemic and cutaneous anaphylaxis mediated by anti-dinitrophenyl IgE. In accordance with these findings, MELE dose-dependently decreased histamine release from RPMC evoked by compound 48/80 or the antigen-antibody reaction. To clarify the mechanism of degranulation system, intracellular cAMP levels as well as calcium influx in RPMC was evaluated. In compound 48/80-treated RPMC, MELE blocked calcium uptake into the cells. In addition, MELE elevated the intracellular cAMP content and significantly attenuated compound 48/80-induced cAMP reduction in RPMC. Taken together, we propose the clinical use of MELE in mast cell-mediated immediate-type allergic diseases.

Objectives : In this study, we investigate the anti-allergic effects of Ullmus macrocarpa Hance (Ulmus) on RBL-2H3 mast cell (basophilic leukemia cell line), which are mediated by FcεRIs. Methods : We evaluated the effect of the ethanol extract of Ulmus on the allergic inflammatory response in IgE-antigen-mediated RBL-2H3 cells. Cell toxicity was determined by MTT assay and the markers of degranulation such as beta-hexosaminidase, histamine, PGD2, TNF-α, IL-4, IL-6 production of inflammatory mediators and FcεRI-mediated protein expression by western blot. Results : Ulmus inhibited degranulation and production of allergic mediators (e.g., TNF-α, IL-4, and IL-6) in them. Ulmus reduced histamine levels, expression of FcεRI signaling-related genes such as Lyn, Syk, and Fyn, and extracellular signal-regulated kinase phosphorylation in mast cells. Also, Ulmus reduced PGD2 release and cyclooxygenase-2 expression, and cytosolic phospholipase A2 phosphorylation in FcεRI-mediated RBL-2H3 mast cells. Conclusions : These results indicate that Ulmus exhibits anti-allergic activity through inhibition of degranulation and inflammatory mediators and cytokine release. These findings suggest that Ulmus may have potential as a prophylactic and therapeutic agent for the treatment of various allergic diseases.
