Objectives : We studied the effects of Radix Asteris herbal acupuncture solution (RAHAS) on the type I hypersensitivity. Methods : In vivo, we measured compound 48/80 induced active systemic anaphylactic shock, anti-DNP IgE induced passive cutaneous anaphylaxis (PCA) and acetic acid induced microvascular permeability using ICR mice. In vitro, we showed effects on cytotoxicity and ${\beta}$-hexosaminidase release from RBL-2H3 cells. Results : In vivo, RAHAS pretreatments at $BL_{13}$ and optional points inhibited active systemic anaphylactic shock induced by compound 48/80 and microvascular permeability increased by acetic acid. PCA was only inhibited by RAHAS pretreatments at $BL_{13}$. In vitro, RAHAS treatments inhibited ${\beta}$-hexosaminidase release. Conclusion : These results suggest that RAHAS may be beneficial in the prevention of type I hypersensitive inflammatory response.

Objectives : We studied the effects of Scutellariae Radix pharmacopuncture solution (SRHAS) on the type 1 hypersensitivity. Methods : In vivo, we measured compound 48/80-induced active systemic anaphylactic shock using ICR mice and anti-DNP IgE-induced passive cutaneous anaphylaxis (PCA) using Sprague Dawley rats. In vitro, we showed effects on cytotoxicity and ${\beta}-hexosaminidase$ release from RBL-2H3 cells. Results : In vivo, SRHAS pretreatments (100% or 50%) at BL13 inhibited active systemic anaphylactic shock induced by compound 48/80. PCA was only inhibited by pretreatments of SRHAS at optional points. In vitro, $0.1{\sim}2%$ SRHAS treatments did not affect cell viability while ${\beta}$-hexosaminidase release was significantly inhibited. Conclusions : These results suggest that SRHAS may be beneficial in the inhibition of type I hypersensitive inflammatory response.

The aim of this study was to evaluate the anti-inflammatory effects of essential oils extracted from the wood of Chamaecyparis obtusa, Pinus densiflora, Pinus koraiensis, and Larix kaempferi. Essential oils were extracted by hydrodistillation, and their chemical components were determined by GC/MS. Major chemical components of these essential oils were ${\alpha}$-cadinol (19.25%), ${\tau}$-muurolol (14.20%), and ${\alpha}$-pinene (13.74%) in C. obtusa; ${\alpha}$-pinene (47.16%), longifolene (14.31%), ${\beta}$-phellandrene (11.78%), and ${\beta}$-pinene (11.02%) in P. densiflora; ${\alpha}$-pinene (13.49%) and longifolene (10.79%) in P. koraiensis, and geranyl linalool (23.58%) and ${\alpha}$-pinene (18.57%) in L. kaempferi. To evaluate the anti-inflammatory effects of essential oils, lipopolysaccharide (LPS)-induced RBL-2H3 mast cells were treated with these essential oils; then, the changes in the mRNA expression level of the cytokines IL-4 and IL-13 were examined. Further, degranulation was evaluated by measuring ${\beta}$-hexosaminidase release. After LPS-induced RBL-2H3 mast cells were exposed to $10^{-7}%$ of all types of essential oils, the gene expression levels of IL-4 and IL-13 within the cells remarkably decreased. The relative mRNA expression level of IL-4 was 69.6% in P. densiflora, 63.2% in P. koraiensis, 55.1% in C. obtusa, and 45.8% in L. kaempferi compared with that in the group treated with LPS. The mRNA expression level of L-13 should a similar trend. The inhibitory rate of IL-13 mRNA expression of P. densiflora, P. koraiensis, C. obtusa, and L. kaempferi was 57.8%, 57.1%, 51.1%, and 34.5%, respectively. ${\beta}$-Hexosaminidase release significantly decreased following the treatment with the four types of essential oils. The rate of ${\beta}$-hexosaminidase release were 38.1% C. obtusa; 33.0% P. densiflora; 27.4% P. koraiensis; and 9.1% L. kaempferi. Among all types of essential oils, that extracted from P. densiflora wood showed the highest anti-inflammatory activity. These results show that the tested essential oils exert an anti-inflammatory effect through the inhibition of degranulation and expression of cytokines.

Objetives : The purpose of this study was to examine the pathway of anti-allergic effects of Aconiti Ciliare Tuber (ACT). Methods : We examined cell viability, ${\beta}$-hexosaminidase release, pro-inflammatory cytokines secretion and mRNA expressions, nuclear factor-kappa B (NF-${\kappa}B$) (p65) activation, inhibitor kappa B-alpha ($I{\kappa}B-{\alpha}$) degradation, and MAPKs activation from RBL-2H3 cells pre-treatment by ACT of 1.0 mg/ml, 2.0 mg/ml separately. Results : We observed that ACT reduced the secretion of ${\beta}$-hexosaminidase, TNF-${\alpha}$, IL-4 and the expression of COX-2 mRNA in RBL-2H3 cells. Futhermore, ACT inhibited the levels of activation of NF-${\kappa}B$ (p65) protein, ERK MAPK, and degradation of $I{\kappa}B-{\alpha}$ in RBL-2H3 cells. Conclusions : These results show that ACT has an anti-histamine effect and inhibitory effect of NF-${\kappa}B$ (p65) through regulation of $I{\kappa}B-{\alpha}$ degradation. This improves that ACT could be used as an anti-allergic medicine.

This study was performed to evaluate the antioxidant activities and anti-asthma effects of Morus bark water extracts. Inhibitory effect of Morus bark onto free radical generation was determined by measuring DPPH and hydroxyl radical scavenging activities in vitro. Anti-asthma activities of Morus bark water extracts were assessed by testing their effects on the degranulation of mast cell. For this, $\beta$-hexosaminidase released from a basophilic cell line, RBL-2H3 was used and pro-inflammatory cytokines were measured by ELISA kit. The antioxidant activities of water extracts of Morus bark was 59.2% in the DPPH assay at $2,000\;{\mu}g/mL$ and 78.8% in the hydroxyl radical scavenging assay at $2,000\;{\mu}g/mL$. Our results indicated that Morus bark water extracts effectively inhibited free radical generation. Morus bark water extracts inhibited inflammation-mediating substances such as histamine and $\beta$-hexosaminidase release from RBL-2H3 cells. Cytokine release demonstrated a more effective blockading ability of the Morus bark water extracts to the release of IL-4 and TNF-$\alpha$ compared to control. These results demonstrate that Morus bark may be beneficial in the treatment of allergic inflammatory disease.

Punica granatum (PG) evidences a variety of physiological properties, including anti-diabetic, anti-cancer, antiinflammatory, anti-microbial, and anti-oxidative activities. Using the human basophilic KU812F cells, the inhibitory effects of the methanolic extract of PG seed, shell, and juice on calcium ionophore, A23187-induced degranulation were assessed. All of the PG extracts inhibited A23187-induced intracellular $Ca^{2+}$ levels, ${\beta}$-hexosaminidase, and histamine release in a dose-dependent manner. These results showed that all of the PG extracts are potent inhibitors of degranulation in allergic reactions, via the suppression of $Ca^{2+}$ influx.

Mast cells are key effector cells in the early phase allergic inflammation and in diverse immunological and pathological processes. In order to understand the effect on reduction of the anti-dinitrophenyl (DNP) IgE antibody-induced β-hexosaminidase release in RBL-2H3 rat mast cells, a novel series of 4-senecioyloxymethyl- 6,7-dimethoxycoumarins (SMDC) was prepared by reacting 4-chloromethyl-6,7-dimethoxycoumarin with various carboxylic acids. Compounds 8-11 with cyclic moiety such as phenyl, thiophenyl, pyridinyl, and furanyl group were found to inhibit-hexosaminidase release more potently (5.98-9.62 μM) than compounds 3- 7 and 12 with acyclic moiety (19.32-76.78 μM). Furthermore, compounds 8 and 9 inhibited IgE-induced ear swelling and significantly reduced systemic passive cutaneous anaphylaxis reaction in mice.
