  • Fructus of Rubus coreanus $M_{IQ.}$. (FRCM) has been used for stuttering urination, prostate gland disease, and impotence in Korean traditional medicine. Water extract of FRCM (WFRCM) treatment significantly attenuated airway hyperreactivity (AHR). Airway recruitment of leukocytes and eosinophils was also markedly reduced by WFRCM administration, suggesting that WFRCM can alleviate the airway inflammation. However, the level of cytokine (IL-4, IL-5, and IL-13) in bronchoalveolar lavage fluid (BALF) and lung was not different compared with positive control. WFRCM reduced the number of draining lymph node cells during OVA-induced allergic asthma. I further examined transcription level of cytokine in lung. WFRCM treatment reduced IL-4 and IL-13 mRNA in lung and inhibited IgE and IgG1 but not IgG2a. My data suggest that WFRCM attenuates OVA-induced allergic asthma through inhibition of Th2 cell response.

  • The effects of Arctii fructus extract on allegenic inflammation were investigated using in vivo and in vitro test models. Firstly, the cytotoxicity of Arctii fructus extract was validated using MTT assay. As a result, Arctii fructus extract showed no cytotoxic potential, while SDS, a positive control, revealed strong cytotoxic effect. In LLNA assay, Arctii fructus extract showed no skin allergenicity. Next, the anti-allergic actions of Arctii fructus extract were evaluated using rodent experimental models. The oral, intraperitoneal and intradermal administration of Arctii fructus extract significantly inhibited the compound 48/80-induced vascular permeability documented by Evans blue extravasation. In addition, Arctii fructus extract showed potent inhibitory effect on passive cutaneous anaphylaxis activated by anti-dinitrophenyl (DNP) IgE when orally administered. In an in vitro study, Arctii fructus extract revealed to possess inhibitory potential on the compound 48/80-induced histamine release from rat peritoneal mast cells. Moreover, Arctii fructus extract inhibited the IL-4 and TNF-${\alpha}$ mRNA induction by PMA and A23187 in human leukemia mast cells, HMC-1. Finally, it revealed that Arctii fructus extract significantly suppressed histamin-provoked antigenic inflammation reactions in human prick test. Taken together, these results suggest that anti-allergic action of Arctii fructus extract may be due to the inhibition of histamine release and cytokine gene expression in the mast cells.

  • 1. Objectives The roots of Sophora flavescens Aiton (SFA) are widely used as a herbal remedy for allergic inflammation. In this study, we invested the effect of SFA on passive cutaneous anaphylaxis reaction and histamin releas and we demonstrated that SFA suppressed the production of pro-inflammatory cytokines, such as tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), interleukin- 6 (IL-6), and interleukin -8 (IL-8), through inhibition of the $NF{\kappa}B$, JNK and p38 pathway in the human mast cell line, HMC-1. 2. Methods To accomplish this, we invested passive cutaneous anaphylaxis reaction and histamin release at an animal experiment. In addition, we investigated the effect of SFA on the production of inflammation-related cytokines in HMC-1 cells that were co-treated with PMA and A23187, which can induce production of pro-inflammatory cytokines. 3. Results and Conclusions SFA induced passive cutaneous anaphylaxis reaction and histamin releas and supressed the expression of TNF-${\alpha}$, IL-6, and IL-8. In addition, the protein levels of TNF-${\alpha}$ were also decreased by SFA treatment. Furthermore, SFA inhibited the nuclear translocation of nuclear factor $NF{\kappa}B$ through inhibition of the phosphorylation and degradation of $I{\kappa}B-{\alpha}$, which is an inhibitor of $NF{\kappa}B$. Moreover, SFA also inhibited induction of MAPKs (JNK, p38) and $NF{\kappa}B$ promoter-mediated luciferase activity. Taken together, these results suggest that SFA could be used as a treatment for mast cell-derived allergic inflammatory diseases.

  • Allergic inflammation is thought to be a Th2 cell-dominant immune response during which tissue-resident fibroblasts produce chemokines which contribute to the recruitment of migratory leukocytes to sites of tissue injury. Thymus and activation-regulated chemokine (TARC; CCL17) is a potent member of the CC chemokine family and a selective chemoattractant for Th2 cells. In order to study the regulatory profiles of TARC production by $TNF-{\alpha}$, $IFN-{\gamma}$, and Il-4 in human normal skin fibroblast, CCD-986sk cell line was used. The expression of TARC protein was measured using ELISA, and mRNA level was detected by RT-PCR. The combination of $TNF-{\alpha}$ and IL-4 induced a time-and dose-dependent synergistic increase in the expression of TARC at both protein and mRNA levels in the cultured human skin fibroblasts. Exposure of the cells to single cytokine had no effect on TARC expression. The high concentration (100 ng/ml) and long incubation time (72 h) of $IFN-{\gamma}$ further enhanced the TARC production induced by $TNF-{\alpha}$/lL-4 in the skin fibroblast. This synergistic effect of Th1 and Th2 type cytokines on TARC production by skin fibroblasts may contribute to the inflammatory cell infiltration and tissue damage with allergic inflammation.

  • Objective This study is to learn the effects of Hataedock method using Coptidis rhizoma and Glycyrrhiza uralensis mixed extract on inflammatory response in allergic rhinitis-induced obese NC/Nga mice. Materials and Methods The mice were fed with high fat-diet to be obese, and were divided into 3 groups as follows; allergic rhinitis-induced obese mice group with Hataedock method (CGT, n=10), no treatment group (Ctrl), allergic rhinitis elicited obese mice group (ARE). To induce allergic rhinitis, NC/Nga mice of 3 weeks age were sensitized on 7, 8 and 9 weeks by ovalbumin antigen in intraperitoneal space. After 7 days of final sensitization, allergic rhinitis was initially induced in mice through nasal cavities for 5 days. After 1-week, allergic rhinitis was induced again by the same method. Histological examination was used to identify distribution of IL-4, CD40, STAT6, $Fc{\varepsilon}RI$, substance P, MMP-9, NF-${\kappa}B$ p65, iNOS and COX-2. Results Hataedock method significantly reduced IL-4, STAT6 and CD40 response (p<0.05). In CGT, the inhibition of Th2 differentiation decreased inflammatory mediators such as $Fc{\varepsilon}RI$, substance P, MMP-9, NF-${\kappa}B$ p65, iNOS and COX-2 (all p<0.05). The immunological improvement led reduction of respiratory epithelial damage and mucin secretion in goblet cell. Conclusion The results of this study show that the Hataedock method suppresses the expression of allergic rhinitis by decreasing the inflammatory mediators through the regulation of Th2 differentiation even when the inflammation reaction is increased by obesity. Therefore, Hataedock may have potential preventive measure of allergic rhinitis accompanied by obese.

  • We have reported that a 24 kDa protein (22U homologous; As22U) of Anisakis simplex larvae could elicit several Th2-related chemokine gene expressions in the intestinal epithelial cell line which means that As22U may play a role as an allergen. In order to determine the contribution of As22U to allergic reactions, we treated mice with 6 times intra-nasal application of recombinant As22U (rAs22U). In the group challenged with rAs22U and ovalbumin (OVA), the number of eosinophils in the bronchial alveolar lavage fluid (BALF) was significantly increased, as compared to the group receiving only OVA. In addition, mice treated with rAs22U and OVA showed significantly increased airway hyperresponsiveness. Thus, severe inflammation around the airway and immune cell recruitment was observed in mice treated with rAs22U plus OVA. The levels of IL-4, IL-5, and IL-13 cytokines in the BALF increased significantly after treatment with rAs22U and OVA. Similarly, the levels of anti-OVA specific lgE and lgG1 increased in mice treated with rAs22U and OVA, compared to those treated only with OVA. The Gro-${\alpha}$ (CXCL1) gene expression in mouse lung epithelial cells increased instantly after treatment with rAs22U, and allergy-specific chemokines eotaxin (CCL11) and thymus-and-activation-regulated-chemokine (CCL17) gene expressions significantly increased at 6 hr after treatment. In conclusion, rAs22U may induce airway allergic inflammation, as the result of enhanced Th2 and Th17 responses.

  • Background &Objectives : Rhinitis is an inflammation of nasal mucosa and the major symtoms are watery rhinorrhea, sneezing, itchy nose, and nasal obstruction. Rhinitis is classified into allergic rhinitis and nonallergic rhinitis. Allergic rhinitis is an immune reaction by allergen, and vasomotor rhinitis which is nonallergic and noninfectious is hypersensitive reaction. The incidence of allergic rhinitis has increased and the rate of vasomotor rhinitis is high. However there have been no studies about vasomotor rhinitis compared with allergic rhinitis. And there have been no studies so far performed on the effect of Tongkwansan. Therefore this study is aimed to find out the effects of Tongkwansan on allergic rhinitis and vasomotor rhinitis. Materials and Methods : Fifteen BALC/c mouses were divided into three groups : normal group, control group and sample group. To induce the allergic rhinitis in control group and sample group, mouses were sensitized intrapertioneally 0.1% ovalbumin solution three times at intervals of 1 week. Then intranasal sensitization was performed by diffusing 0.1 % ovalbumin solution 3 times at intervals of 2 days. After that time, mouses in the sample group were oral administration treated by Tongkwansan for 28 days. We observed changes in the segment of IL-4, IL-5, $IFN-{\gamma}$, Total IgE, and ovalvumin specific IgE in blood. We used the statistical methods of ANOVA test(p<0.05). Results : There were no significant changes statistically in $IFN-{\gamma}$, IL-4, and IL-5 in blood(p<0.05). There were also no significant changes statistically in Total IgE, OVA-specific IgE in blood(p<0.05). Conclusion : According to above results, it is supposed that Tongkwansan has no significant effects on allergic rhinitis. But it is supposed that Tongkwansan has significant effects on vasomotor rhinitis which is nonallergic and noninfectious

  • The aim of this study is to evaluate the anti-inflammatory effect of Hataedock treatment using Coptidis Rhizome and Glycyrrhiza Uralensis (CG) mixed extract in allergic rhinitis induced NC/Nga mice. We divided NC/Nga mice into 3 groups as follows; allergic rhinitis-induced group after CG Hataedock treatment (CGT, n=10), no treatment group (Ctrl), allergic rhinitis elicited group (ARE). To induce allergic rhinitis, NC/Nga mice of 3 weeks age were sensitized on 7, 8 and 9week by Ovalbumin (OVA) antigen in intranasal space. Hataedock using CG extract was administered on week 3 in allergic rhinitis-induced group (CGT) after Hataedock treatment. To identify distribution of Interlukin (IL)-4, Cluster of differentiation 40 (CD40), high-affinity IgE receptor ($Fc{\varepsilon}RI$), substance P, Matrix metallopeptidase 9 (MMP-9), Nuclear $factor-{\kappa}B$ ($NF-{\kappa}B$) p65, Inducible nitric oxide synthase (iNOS) and Cycloxygenase-2 (COX-2), we used histological examination. CGT significantly inhibited IL-4 and CD40 response compared with ARE. The reduction of Th2 cytokine expression decreased inflammatory mediators such as $Fc{\varepsilon}RI$, substance P, MMP-9, $NF-{\kappa}B$ p65, iNOS and COX-2. Such immunological improvement induced reduction of respiratory epithelial damage and mucin secretion in goblet cell. These results indicate that Hataedock treatment suppresses allergic rhinitis through modulating of Th2 responses and diminishing various inflammatory mediators in nasal mucosal tissue. It might have potential applications for prevention and treatment of allergic rhinitis.

  • Objective : Allergic Inflammation is related with secretion of Cytokine. This study was performed to examine the effects of Woobangja on anti-allergic inflammation. 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.

  • 본 연구에서는 표고버섯(Lentinula edodes)을 자외선 조사를 통한 ergocaciferol (비타민 D2) 함량을 증진시킨 추출물을 이용하여 염증 및 알레르기 반응에 미치는 효과를 확인하였다. 표고버섯 추출물의 항염증 및 항알레르기 효능은 LPS로 활성화된 대식세포(RAW 264.7)와 PMA와 A23187에 의해 활성화된 비만세포(RBL-2H3)로부터 분비 또는 발현되는 TNF-α, IL-6, IL-1β, IL-4와 같은 cytokine과 histamine 분비량을 측정하여 관찰하였다. LPS에 의해 활성화된 대식세포에서 자외선 조사 표고버섯 추출물 처리에 의해 pro-inflammatory cytokine인 TNF-α와 IL-6의 분비량을 ELISA 방법으로 측정하였을 때 현저히 감소함을 확인하였고 mRNA 발현 또한 감소됨을 확인하였다. 비만세포에 자외선 조사 표고버섯 추출물과 PMA, A23187을 함께 처리한 경우 비만세포의 탈과립에 의해 분비되는 histamine의 양이 유의적으로 감소함을 확인하였고 IL-4의 발현양 또한 감소함을 확인할 수 있었다. 이상의 결과는 자외선 조사에 의해 비타민 D2 함량을 증진시킨 표고버섯 추출물이 염증과 알레르기 반응의 cytokine의 발현을 저해하는 것으로 보아 염증 및 알레르기 질환의 예방과 치료에 효과적으로 이용될 수 있을 것으로 사료된다.
