본 연구는 국내산 편백, 소나무, 잣나무, 일본잎갈나무 목부 정유의 항염증 효과를 평가 하였다. 실험에 사용된 정유는 각 수종의 목부에서 증류법(hydrodistillation)으로 추출되었다. 추출한 정유들을 GC-MS를 통해 성분 분석한 결과, 편백의 경우 ${\alpha}$-cadinol (19.25%), ${\tau}$-muurolol (14.20%) 및 ${\alpha}$-pinene (13.74%)이, 소나무는 ${\alpha}$-pinene (47.16%), longifolene (14.31%), ${\beta}$-phellandrene (11.78%) 및 ${\beta}$-pinene (11.02%)이 주요성분이었으며, 잣나무의 경우 ${\alpha}$-pinene (13.49%)와 longifolene(10.79%), 낙엽송의 경우 geranyl linalool (23.58%) 및 ${\alpha}$-pinene (18.57%)이 주요성분으로 확인되었다. 침엽수 목부 정유들의 항염증 효과는 LPS(Lipopolysaccharide)로 염증반응이 유도된 RBL-2H3 비만세포주에 정유를 처리한 후 IL-4(interleukin-4), IL-13(interleukin-13), ${\beta}$-hexosaminidase의 발현 변화를 조사함으로써 평가하였다. MTT assay를 통한 세포 독성 평가 결과, 침엽수 4종 정유 모두 $10^{-7}{\sim}10^{-5}%$ 농도에서 세포 독성을 보이지 않았다. 염증반응이 유도된 RBL-2H3 세포에 침엽수 4종의 목부 정유를 $10^{-7}%$ 농도로 처리하였을 때, LPS 처리군 대비 침엽수 4종의 목부 처리군에서 IL-4와 IL-13의 상대적 발현량이 큰 폭으로 감소하였으며, ${\beta}$-hexosaminidase 분비가 유의하게 억제되었다. 침엽수 정유 4종의 IL-4 상대적 발현량은 LPS 처리군 대비 소나무 69.6%, 잣나무 63.2%, 편백 55.1% 그리고 낙엽송 45.8% 감소하였다. IL-13의 상대적 발현량은 소나무 57.8%, 잣나무 57.1%, 편백 51.1% 그리고 낙엽송 34.5% 감소하였다. ${\beta}$-Hexosaminidase 분비의 경우 LPS 처리군 대비 편백 38.1%, 소나무 33.0%, 잣나무 27.4% 그리고 낙엽송 9.1% 억제하였다. Il-4, IL-13 및 ${\beta}$-hexosaminidase 분비를 비교한 결과, 침엽수 목부 정유 4종 중 소나무 정유의 활성이 가장 우수하였다. 이러한 결과는 국내 침엽수 4종의 목부 정유는 염증반응을 유발하는 싸이토카인의 발현 억제를 통하여 항염증 효과를 나타냄을 확인할 수 있었다.

Background: BIOGF1K, a fraction of Panax ginseng, has desirable antimelanogenic, anti-inflammatory, and antiphotoaging properties that could be useful for treating skin conditions. Because its potential positive effects on allergic reactions in skin have not yet been described in detail, this study's main objective was to determine its efficacy in the treatment of atopic dermatitis (AD). Methods: High-performance liquid chromatography was used to verify the compounds in BIOGF1K, and we used the (3-4-5-dimethylthiazol-2-yl)-2-5-diphenyltetrazolium bromide method to determine its cytotoxicity in RBL-2H3 and HMC-1 cell lines. RBL-2H3 cells were induced using both anti-DNP-IgE/DNP-BSA and calcium ionophore (A2187) treatments, whereas HMC-1 cells were induced using A2187 alone. To measure mast cell degranulation, we performed histamine (enzyme-linked immunosorbent assay) and β-hexosaminidase assays. To quantify interleukin (IL)-4, IL-5, and IL-13 levels in RBL-2H3 cells, we performed quantitative polymerase chain reaction (PCR); to quantify expression levels of IL-4 and IL-13 in HMC-1 cells, we used semiquantitative reverse transcription polymerase chain reaction (RT-PCR). Finally, we detected the total and phosphorylated forms of extracellular signal-regulated kinase, p-38, and c-Jun N-terminal kinase proteins by immunoblotting. Results: BIOGF1K decreased the AD response by reducing both histamine and β-hexosaminidase release as well as reducing the secretion levels of IL-4, IL-5, and IL-13 in RBL-2H3 cells and IL-4 and IL-13 in HMC-1 cells. In addition, BIOGF1K decreased MAPK pathway activation in RBL-2H3 and HMC-1 cells. Conclusions: BIOGF1K attenuated the AD response, hence supporting its use as a promising and natural approach for treating AD.

Objectives : Scutellaria barbata has been widely used in oriental medicine used for treatment of acute and chronic inflammatory diseases. In this study, to investigate the protective effect of Scutellaria barbata on type I allergic response, we determined whether Scutellaria barbata inhibits early or late allergic responses. Methods : To assess the effect of Scutellaria barbata Pharmacopuncture Extract(SB) in RBL-2H3 cells, we investigated the levels of the markers of degranulation such as ${\beta}$-hexosaminidase and histamine, inflammatory mediator such as IL-4, TNF-${\alpha}$, PGE2 and cysLT, and mRNA expression of cytokines and enzymes. In addition, we determined the levels of intracellular ROS by DCFH-DA assay and the free radical scavenging activity by DPPH method. Results : We found that SB suppressed the release of ${\beta}$-hexosaminidase and histamine and the production of IL-4, TNF-${\alpha}$, PGE2 and cysLT in RBL-2H3 by the antigen stimulation. SB also significantly inhibited the enzyme mRNA expressions, such as HDC2, COX-1, COX-2, 5-LOX and iNOS2, along with reduced cytokine mRNA expressions, such as IL-$1{\beta}$, IL-2, IL-3, IL-4, IL-5, IL-6, IL-13, TNF-${\alpha}$ and GM-CSF in RBL-2H3. In addition, SB suppressed the levels of intracellular ROS. Conclusions : Our results indicate that SB protects against type I allergic response and exert an anti-inflammatory effect through the inhibition of degranulation, inflammatory mediator release and mRNA expression of cytokines and enzymes.

The purpose of this study was to investigate Anti-allergic Inflammatory Effects of Hwangyounhaedog-tang on PMA plus A23187-stimulated RBL-2H3 cells. We examined MTT assay, ${\beta}$-hexosaminidase activity, IL-4 and TNF-${\alpha}$ from RBL-2H3 after pre-treatment with HHT. In addition, we investigated expression of COX-1 and COX-2 mRNA using RT-PCR study. The results are as follows: All the concentrations of HHT from 1 to 4 mg/ml didn't have an effect on cell viability. In RBL-2H3 cells, ${\beta}$-hexosaminidase release, IL-4 and TNF-${\alpha}$ were significantly reduced by treated all concentrations of HHT. COX-2 on mRNA expression was reduced at treatment 2mg of HHT prior to stimulating by A23187. These results indicate that HHT has inhibition effects on allergy in this study.

Background: Allergic diseases like such as atopic dermatitis, asthma, and rhinitis have recently increased both domestically and globally. The present study was undertaken to select candidates with anti-allergic activity from plant resources. Methods and Results: Fifty-six plant extracts at $20{\mu}g/m{\ell}$ were screened against ${\beta}$-hexosaminidase production and interleukin (IL)-4 release in degranulated rat basophilic leukemia (RBL)-2H3 cells. The anti-allergy activity of three plant extracts selected from the preliminary screening experiment, Polygonatum sibiricum F. Delaroche (root), Pyrus pytifolia var. culta (Makino) Nakai (leaf), and Rehmannia glutinosa (Gaertn.) Libosch. ex Steud (root) were measured at concentrations of $2-250{\mu}g/m{\ell}$ in three cell lines as RBL-2H3, HaCaT and Jurkcat T cells. The assay showed the root extract of R. glutinosa to have an inhibitory activity of 4.2% - 28.6% on ${\beta}$-hexosaminidase production from IgE-sensitized RBL-2H3 cells. Each extract of P. sibiricum and R. glutinosa reduced IL-4 release in IgE-sensitized RBL-2H3 cells, respectively. The leaf extract of P. pyrifolia var. culta showed a significantly potent suppressive effect of 10.2% - 74.7% on the mRNA expression of tumor necrosis factor (TNF)-${\alpha}$ in HaCaT cells sensitized with TNF-a and INF-g, and showed inhibitory effect of -8.6% - 90.9% on the mRNA expression of IL-2 in Jurkat T cells sensitized with PMA and A23187. Conclusions: The results showed that the root of R. glutinosa and leaf of P. pyrifolia var. culta could be useful candidates as antiallergy materials.
