Objective : To demonstrate of regulatory effect of atopic allergic regulation by Chungsangbangpoong-Tang(CBT), This experiment was studied. Methods : The author investigated a possible effect of CBT on cytokines production using human T cell line (MOLT-4) or human mast cell line (HMC-1). In addition, the author investigated whether CBT has inhitory effects on compound 48/80- induced histamine release from rat peritoneal mast cells (RPMC) and compound 48/80-induced ear swelling in ICR mice. Results : CBT (0.01 mg/ml)-containing medium in stimulated culture supernatants significantly increased IL-2 secretion compared with untreated MOLT-4, whereas CBT (0.01-1.0 mg/ml)-containing medium in stimulated culture supernatants significantly decreased IL-4 secretion compared with untreated MOLT-4. Significant reduced levels of IL -6 and $TNF-{\alpha}$ were observed in the HMC-l with CBT (P<0.05). CBT did not inhibit the histamine release from the RPMC but inhibit ear swelling response. Conclusion : These results suggest that CBT contributes to the treatment of atopic allergic reactions, such as atopic dermatitis and that its action may be due to regulation of cytokine production.

Objective: Danguieumja-gagambang (DGEJGB), a traditional Korean prescription, has been used as therapeutics for allergic diseases such as atopic dermatitis (AD). In this study, we compared with regulatory Effect of Atopic Allergic Reaction by Prescriptions A and by Prescriptions B. Methods : To evaluate and compare the atopic allergic effectiveness of two prescription (A, B) of DGEJGB, the author investigated a possible effect of DGEJGB on mast cell-mediated allergic reaction, cytokine secretion and mRNA expression in vivo and in vitro. Results : Mast cells are a potent source of mediators that regulate the inflammatory response in allergic reaction. In mice orally administered A, B of DGEJGB ( 0.1, 0.1 and 1.0 g/kg) for 1 h, compound 48/80-induced ear swelling was significantly reduced. Significant reduced levels (P < 0.05). of tumor necrosis factor $(TNF)-{\alpha}$ was observed in the human mast cell line (HMC-1) with DGEJGB (A). IL-6 and IL-8 secretion were significantly inhibited by DGEJGB (A, B). In addition, $TNF-{\alpha}$ and IL-8 mRNA expression were reduced by DGEJGB (A) at the dose of 0.01 mg/ml without cell toxicity. Conclusions : These results suggest that DGEJGB (A) contributes to the treatment of atopic allergic reactions rather than DGEJGB (B), and that its action may be due to inhibition of cytokine secretion and mRNA expression HMC-1.

Objective : Atractyloides Chinensis Rhizome (ACR) is widely used in oriental medicine as a remedy for an inflammation and an allergic disease. However, as yet there is no clear explanation of how ACR affects the production of inflammatory cytokine. This study was to determine the effects of ACR on the mast cell-mediated inflammatory responses. Method : The amount of inflammatory cytokine production induced by the phorbol myristate acetate (PMA) plus calcium ionophore(A23187) in the human mast cell line (HMC-1) incubated with various concentrations of ACR was measured. The TNF-${\alpha}$ protein levels were analysised by Western blots. The TNF-${\alpha}$, IL-6 and IL-8 secreted protein levels were measured by the ELISA assay. The TNF-${\alpha}$, IL-6 and IL-8 mRNA levels were measured by the RT-PCR analysis. NF-${\kappa}$B, phospho-I${\kappa}$B and MAPKs were examined by Western blot analysis. The NF-${\kappa}$B promoter activity was examined by a luciferase assay. Results : 1. The expressions of TNF-${\alpha}$ and TNF-${\alpha}$ mRNA were decreased dose-dependently at 0.05-0.2mg/$m\ell$ of ACR and significantly decreased at 0.2mg/$m\ell$. 2. The expressions of IL-6 and IL-6 mRNA were decreased dose-dependently at 0.05-0.2mg/$m\ell$ of ACR and significantly decreased at 0.2mg/$m\ell$. 3. The expressions of IL-8 and IL-8 mRNA were decreased dose-dependently at 0.05-0.2mg/$m\ell$ of ACR and significantly decreased at 0.2mg/$m\ell$ specially. 4. The expressions of Phosphorylated-JNK were decreased, not p38, ERK 5. The expressions of NF-${\kappa}$B were decreased dose-dependently at 0.1-0.2mg/$m\ell$ of ACR. The expressions of Phosphorylated I${\kappa}$B were significantly decreased at 0.2mg/$m\ell$. In addition, ACR suppressed PMA plus A23187-induced NF-${\kappa}$B promoting activity. Conclusion : It is suggested that ACR should suppress through inhibition of NF-${\kappa}$B activity and cytokine production.

The effects of aqueous extract of Artemisia iwayomogi (Compositae) (AIAE) on the mast cell-dependent allergic and inflammatory reactions were investigated. AIAE (0.05 to 1 g/kg) dose-dependently inhibited systemic allergic reaction induced by compound 48/80 in mice. AIAE (0.1 and 1 g/kg) also significantly inhibited local allergic reaction activated by anti-DNP IgE. AIAE (0.001 to 1 mg/ml) dose-dependently inhibited the histamine release from rat peritoneal mast cells (RPMC) activated by compound 48/80. Moreover, AIAE inhibited the secretion of interleukin (IL)-6 in phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore A23187-stimulated human mast cell line (HMC-1) cells. These results provide evidence that AIAE may be beneficial in the treatment of allergic diseases.

Perilla frutescens var. acuta Kudo (PF) is a traditional Korean medicinal herb for allergic reaction regulation. In the present study, we investigated the effect of 30% ethanol extract powder of PF (EPPF) and rosmarinic acid (RA), the active compound of EPPF on various allergic reactions using in vivo and in vitro models. EPPF and RA significantly inhibited compound 48/48-induced systemic anaphylactic reaction and histamine release (P < 0.05). In addition, EPPF and RA significantly inhibited passive cutaneous anaphylaxis (PCA) in a dose-dependent manner (P < 0.05). These effects were stronger than those of disodium cromoglycate, the reference drug tested. EPPF and RA also significantly inhibited production of inflammatory cytokines, tumor necrosis factor-a interleukin (IL)-6, and vascular endothelial growth factor on the PCA reaction and phorbol 12-myristate 13-acetate and calcium ionophore A23187-stimulated human mast cell line, HMC-1 cells (P < 0.05). Moreover, EPPF and RA showed an inhibitory effect on lipopolysaccharide (LPS)-induced IL-4 production from whole spleen cells. Finally, EPPF and RA significantly decreased IL-4-dependent IgE production by LPS-stimulated whole spleen cells (P < 0.05). In conclusion, these results indicate that EPPF has potent anti-allergic activities.

Ji-Jang-Soo (JJS) is known to have a detoxification effect. However, it is still unclear how JJS has these effects in experimental models. In this study, we investigated the effect of JJS on the viability of cells and production of cytokines in human T-cell line, MOLT-4 cells, and human mast cell line, HMC-1 cells. The MOLT-4 cells were cultured for 24 h in the presence or absence of JJS. As the result, JJS (1/100 dilution) significantly increased the cell viability about 78% (P < 0.05) and also increased the interleukin (IL)-2, and interferon $(IFN)-{\gamma}$ production compared with media control at 24 h. But had no effect on IL-4 production. Hypoxia mimic compound, desferroxamine (DFX) decreased the immune cell viability. Cell viability decreased by DFX was increased by JJS. In conclusion, these data indicate that JJS may have an immune-enhancing effect.

Goat milk has a protein composition similar to that of breast milk and contains abundant nutrients, but its use in functional foods is rather limited in comparison to milk from other sources. The aim of this study was to prepare a goat A2 ${\beta}$-casein fraction with improved digestibility and hypoallergenic properties. We investigated the optimal conditions for the separation of A2 ${\beta}$-casein fraction from goat milk by pH adjustment to pH 4.4 and treating the casein suspension with calcium chloride (0.05 M for 1 h at $25^{\circ}C$). Selective reduction of ${\beta}$- lactoglobulin and ${\alpha}_s$-casein was confirmed using sodium dodecyl sulphate-polyacrylamide gel electrophoresis and reverse-phase high-performance liquid chromatography. The hypoallergenic property of A2 ${\beta}$-casein fraction was examined by measuring the release of histamine and tumor necrosis factor alpha from HMC-1 human mast cells exposed to different proteins, including A2 ${\beta}$-casein fraction. There was no significant difference in levels of both indicators between A2 ${\beta}$-casein treatment and the control (no protein treatment). The A2 ${\beta}$-casein fraction is abundant in essential amino acids, especially, branched-chain amino acids (leucine, valine, and isoleucine). The physicochemical properties of A2 ${\beta}$-casein fraction, including protein solubility and viscosity, are similar to those of bovine whole casein which is widely used as a protein source in various foods. Therefore, the goat A2 ${\beta}$-casein fraction may be useful as a food material with good digestibility and hypoallergenic properties for infants, the elderly, and people with metabolic disorders.
