In the present study, we investigated the effect of the water extract of Perilla frutescens var. acuta (Labiatae; WEPF) on the mast cell-mediated allergic reactions. WEPF was anally administered to mice for high and fast absorption. WEPF inhibited compound 48/80-induced systemic allergic reaction. WEPF attenuated immunoglobulin E (IgE)-mediated local allergic reaction. In addition, WEPF decreased the gene expression of pro-inflammatory cytokines in phorbol 12-myristate 13-acetate plus calcium ionophore A23187 (PMACI)-stimulated HMC-1 cells. These results indicate that WEPF inhibits mast cell-mediated allergic reactions in vivo and in vitro.

본 연구에서 장류 및 젓갈 유래 균체를 각각 sonication, $100^{\circ}C$에서 30 min, $125^{\circ}C$에서 15 min의 조건으로 추출하여 HMC-1에 처리하였을 때, 이 추출방법에 따른 HMC-1매개 염증반응 억제효과를 조사하였다. 추출방법을 달리하여 추출한 장류 및 젓갈 유래 균체 J80, G147이 HMC-1생존율에 미치는 영향은 대조구 B (Not treated)와 비교하였을 때 86~96%로 유의적 차이를 보이지 않아 장류 및 젓갈 유래 균체에 의한 세포 독성은 나타나지 않았다. 장류 및 젓갈 유래 균체의 모든 전처리구에서 histamine 유리 억제효과를 나타내었으며 특히, $100^{\circ}C$에서 30 min 동안 가열하였을 때 histamine 억제율이 J80에서 28.86%, G147에서 41.14%으로 가장 높게 나타냈다. IL-8 분비량은 J80, G147의 모든 전처리구에서 IL-8 분비억제효과가 나타났으며, J80의 경우 $100^{\circ}C$, 30 min에서 처리한 구에서 분비량이 0.78 ng/ml로 대조구 B (Not treated)에 비하여 약 28.45%의 분비억제효과로 가장 높게 나타내었다. G147의 경우 $125^{\circ}C$, 15 min에서 처리한 구에서 분비량이 0.73 ng/ml로 약 36.52%의 분비억제효과로 가장 높게 나타내었다. IL-6 분비량을 측정한 결과 J80, G147의 모든 실험구에서 IL-6 분비억제효과가 나타났으며, J80에서는 $100^{\circ}C$, 30 min한 D구의 분비량이 0.40 ng/ml으로 대조구 B (Not treated)에 비하여 약 38.46%의 분비억제효과로 가장 높았으며, G147 역시 $100^{\circ}C$, 30 min 동안 처리한 D구의 분비량이 0.27 ng/ml으로 대조구 B (Not treated)에 비하여 56.45%의 분비억제효과로 가장 높게 나타냈다. TNF-${\alpha}$ 분비량 역시 IL-6와 마찬가지로 J80, G147에서 대조구 B보다 낮은 분비량으로 TNF-${\alpha}$ 분비 억제효과가 나타났으며 J80의 경우 $100^{\circ}C$, 30 min 처리한 D의 TNF-${\alpha}$ 분비량이 0.052 ng/ml으로 66.67%의 분비억제효과로 가장 높았으며, G147의 경우 sonication을 처리한 C구의 TNF-${\alpha}$ 분비량이 0.086 ng/ml으로 41.1%의 분비억제효과로 다른 구에 비해 높은 억제효과를 나타내었다. 위의 결과를 통해서 장류 및 젓갈 유래 균체의 3가지 전처리 방법 중 $100^{\circ}C$, 30 min 처리 시 염증 반응 억제 효과가 가장 높을 것으로 예상된다. 결과를 미루어보아 장류를 섭취하는 대표적인 방법인 가열하여 찌개로 조리과정 중 장류 및 젓갈 속의 균체가 열에 가열되면서 염증억제효과 높일 수 있는 가장 좋은 조리 방법으로 사료되며, 이는 대중들이 가장 가깝게 염증반응 억제효과를 볼 수 있는 식품일 것이다. 또한 염장처리과정만을 거친 젓갈을 섭취하는 것보다 열처리과정을 거친 젓갈을 섭취할 경우 염증억제효과를 더 높일 수 있을 것으로 예상된다.

Lonicerae Flos containing formulation, Geumeumyoungji-tang (GYT), is an herbal prescription prepared using 5 different herbal drugs, namely, Lonicerae Flos, Ganoderma, Lactucae Herba, Xanthii Fructus, and Smilacis Rhizoma. This study was focused on the investigation of the pharmacological effects of GYT on allergic reactions. As the first step of the study, GYT was administered BALB/c mice which were sensitized by 2,4-dinitrofluorobenzene (DNFB). As the result GYT ameliorated dermatitis provoked by DNFB. The serum IgE level of the DNFB sensitized-mouse was significantly decreased when GYT was administered. In order to confirm the moderating effect of this prescription on allergic reaction, GYT was pretreated to human mast cells (HMC-1) before they were stimulated by phorbol-12-myristate 13-acetate plus calcium ionophore A23187 (PMACI). GYT suppressed secretion of inflammatory cytokines, interleukin (IL)-6 and IL-8, from HMC-1. Additionally, pretreatment of GYT showed regulating effect on COX-2 expression. Collectively, these findings provide insights into the pharmacological actions of GYT as a potential agent for treatment of allergic dermatitis.

Samsoeum (SSE) is used in traditional oriental medicine for various medicinal purposes. However, the exact mechanism that accounts for the anti-allergy and anti-inflammatory effects of the SSE is still not fully understood. The aim of the present study is to elucidate whether and how SSE modulates the allergic reactions in vivo, and inflammatory reaction in vitro. In this study, we showed that SSE significantly decreased compound 48/80-induced systemic anaphylaxis, ear-swelling response, histamine release from preparation of rat peritoneal mast cells and anti-dinitropheny IgE-induced passive cutaneous reaction. Also, SSE inhibited the expression of inflammatory cytokine and cyclooxygenase-2 in PMA plus A23187-stimulated human mast cells (HMC-1). In addition, we showed that anti-inflammatory mechanism of SSE is through suppression of nuclear factor-${\kappa}B$ activation and $I{\kappa}B-{\alpha}$ phosphorylation/degradation in HMC-1. These results provided new insight into the pharmacological actions of SSE as a potential molecule for therapy of inflammatory allergic diseases.

Atopic dermatitis (AD) is a common inflammatory skin disorder mediated by inflammatory cells, such as macrophages and mast cells. Rifampicin is mainly used for the treatment of tuberculosis. Recently, it was reported that rifampicin has anti-inflammatory and immune-suppressive activities. In this study, we investigated the effect of rifampicin on atopic dermatitis in vivo and in vitro. AD was induced by treatment with 2, 4-dinitrochlorobenzene (DNCB) in NC/Nga mice. A subset of mice was then treated with rifampicin by oral administration. The severity score and scratching behavior were alleviated in the rifampicin-treated group. Serum immunoglobulin E (IgE) and interleukin-4 (IL-4) levels were also ameliorated in mice treated with rifampicin. We next examined whether rifampicin has anti-atopic activity via suppression of mast cell activation. Rifampicin suppressed the release of ${\beta}$-hexosaminidase and histamine from human mast cell (HMC)-1 cultures stimulated with compound 48/80. Treatment with rifampicin also inhibited secretion of inflammatory mediators, such tumor necrosis factor-${\alpha}$ ($TNF-{\alpha}$) and prostaglandin $D_2$ ($PGD_2$), in mast cells activated by compound 48/80. The mRNA expression of cyclooxygenase 2 (COX-2) was reduced in the cells treated with rifampicin in a concentration-dependent manner. These results suggest that rifampicin can be used to treat atopic dermatitis.

Gamisaenghyeolyunbueum (GSYE) is a traditional Oriental herbal medicine prescription, which has been used for the treatment of various allergic disorders, atopic dermatitis, extravasated bleeding from skin, especially skin related disease. The author investigated the effects of GSYE on mast cell-mediated allergic inflammatory reactions. GSYE dose-dependently (0.01-1 g/kg) inhibited compound 48180-induced systemic anaphylactic shock and ear swelling response. The inhibitory effect of GSYE on the histamine release from rat peritoneal mast cells induced by compound 48f80 reveals significantly (p<0.05) at concentrations ranging from 0.01 to 1 mg/ml in a dose-dependent manner. GSYE also inhibited the passive cutaneous anaphylaxis(PCA) by oral administration at 1 g/kg. In addition, GSYE dose-dependently (0.01-1 g/kg) inhibited the phorbol 12-myristate 13-acetate(PMA) and A23187-induced tumor necrosis $factor-{\alpha}$ secretion from human mast cell line HMC-1 cells. These results indicate that GSYE may be a beneficial applicability in the allergic-related diseases.

Lactococcus lactis is a lactic acid bacterium and used in the dairy food industry. The ameliorating effects of Lactobacillus species on atopic dermatitis (AD) have been extensively studied, but the specific effect of L. lactis strains has not yet been investigated. In this study, the efficacy of L. lactis LB 1022, isolated from natural cheese, was evaluated using RAW 264.7, HMC-1 and HaCaT cell lines and an ovalbumin-sensitized AD mouse model. L. lactis LB 1022 exhibited nitric oxide suppression and anti-allergy and anti-inflammatory activity in vitro. Oral administration of L. lactis LB 1022 to AD mice significantly reduced the levels of IgE, mast cells, and eosinophils, and a range of T cell-mediated T helper Th1, Th2, and Th17-type cytokines under interleukin (IL)-10, transforming growth factor-β (TGF-β), thymus and activation-regulated chemokine (TARC), and thymic stromal lymphopoietin (TSLP). In addition, L. lactis LB 1022 treatment increased the concentration of short-chain fatty acids. Overall, L. lactis LB 1022 significantly modulated AD-like symptoms by altering metabolites and the immune response, illustrating its potential as candidate for use in functional food supplements to alleviate AD.
