The present study was conducted to investigate the anti-allergic activity of Galgeunhaegi-Tang(GHT). We investigated the anti-allergic effects of GHT in RBL-2H3 basophilic leukemia cells by compound48/80, a mast cell degranulator and compound 48/80 induced anaphylactic shock in mice. GHT significantly inhibited ${\beta}$-hexosaminidase and histamine release from compound 48/80 stimulated RBL-2H3 cells. In addition, GHT effectively inhibited anaphylactic shock in mice by 40% at a dose 100 mg/mouse versus PBS treated control after the l.p injection(8 mg/kg) of compound 48/80. The in vitro anti-inflammatory activities of GHT in LPS-stimulated RAW 264.7 cells were investigated. GHT inhibited NO production in LPS-stimulated RAW 264.7 cells and effectively dowregulated the expression of iNOS mRNA and iNOS protein expression in LPS-stimulated RAW 264.7 cells. These result provide evidences that GHT may be beneficial in the treatment of allergic inflammtory disease.

Effects of Panax ginseng on allergic reactions were studied uslng various in vivo and in vitro experimental models such as 48-hr passive cutaneous anaphylaxis, mediators-induced skin reactions, histamine release from rat peritoneal mast cells, hexosaminidase release from RBL-2H3 cells, and lipoxygenase assay . In all of anti-allergic experiments we conducted, ginseng components (50% ethanol extract or ginseng total saponin or ginsenosides) extracted from Korean red ginseng, did not show significant anti-allergic actions. In 48-hr passive cutaneous anaphylaxis and mediators-induced skin reactions, 50% ethanol extract did not suppress hypersensitivity reactions. Total saponin, 50% ethanol extract, and 8 major ginsenosides did not show inhibitory effects on lipoxygeanse activity. Ginseng total saponin did not inhibit histamine release from rat peritoneal mast cells. All of the ginseng components mentioned above were also tested on RBL-2H3 cells, but none of them inhibited hexosaminidase release from this cell line. These results suggest that Panax ginseng does not have effects on allergic reactions at the level of 50% ethanol extract or total saponin used. All of 8 major saponin components tested ($Rb_1$, $Rb_2$, Rc, Rd, Re, Rf, $Rg_1$, $Rg_2$), did not inhibit lipoxygenase activity and degranulation events.

Objectives : In this study, we investigated the effect of modified-Okbyungpoongsan (mOP) on mast cell-mediated allergic response in basophilic leukemia cell line, RBL-2H3 mast cells. Methods : Cells were stimulated with anti-DNP-IgE after the treatment of DNP-HSA (AI/D), and then incubated with different concentrations of mOP (0.1, 0.2, 0.5 and 1 mg/$m{\ell}$) in RBL-2H3 cells. Cell toxicity was determined by WST-1 assay. The degranulation of mast cells was observed by microscope with toluidine blue staining and also the levels of beta-hexosaminidase, histamine and TNF-alpha were measured in culture supernatants by enzyme-linked immunosorbant assay. Results : mOP inhibited anti-DNP-IgE-imduced degranulation of mast cells in RBL-2H3 cells. mOP also significantly decreased the levels of histamine and inflammatory cytokine, TNF-alpha in RBL-2H3 cells, but slightly decreased the level of beta-hexosaminidase. Conclusions : These results indicate that mOP, an oriental prescription could be inhibit the allergic response through suppressing the mast cell activation.

The marine carotenoid fucoxanthin can be found in marine brown seaweeds, macroalgae, diatoms, and microalgae, and has remarkable biological properties. Numerous studies have shown that fucoxanthin has considerable potential and promising applications in human health, but the underlying mechanisms involved in its anti-allergic activity are not fully understood. We here investigated the mechanisms by anti-allergic activity of fucoxanthin fraction from Eisenia bicyclis in immunoglobulin E-antigen complex (IgE/DNP-BSA)-stimulated RBL-2H3 mast cells. This study we found that the fucoxanthin inhibits the release of ${\beta}$-hexosaminidase and suppressed not only transcriptional activation of NF-${\kappa}B$, but also phosphorylation of ERK and JNK in IgE/DNP-BSA-treated RBL-2H3 cells. Fucoxanthin may be useful for preventing allergic diseases, including asthma and atopic dermatitis.

홍삼은 인삼을 증숙하는 과정에서 생겨나는 화학적으로 변화된 생리활성물질들에 의해 인삼과 차별화된 효과를 보여준다. 또한 홍삼은 장내미생물의 생물학적 전환에 의해 변화되어 생체내 약리활성을 보이는데, 이는 개인의 장내 미생물의 분포 차이에 의해 약리작용의 차이를 보일 수 있다. 최근 이 같은 차이를 극복하기 위해 인위적으로 장내미생물에 의해 사전 발효시킨 발효홍삼은 홍삼과 다른 성분량의 차이를 보임으로써 독특한 약리작용을 보인다고 알려져 있다. 이에 본 연구는 홍삼과 발효홍삼의 추출물이 알러지 및 염증반응에 끼치는 영향에 대해 알아보기 위해 비만세포의 탈과립 과정에서 분비되는 $\beta$-hexosaminidase 분비량 비교, 염증매개 세포부착물질인 ICAM-1 발현비교, 생쥐림프구의 증식능, 각질형성세포 증식능을 상호 비교하였다. 실험결과 홍삼은 1, $10\;{\mu}g/ml$에서 $\beta$-hexosaminidase 분비량 억제 및 ICAM-1 발현 억제 조절 효과를 나타내었으며, 발효 홍삼은 모든 농도에서 유의적인 억제 효과를 나타내었다. 그러므로 홍삼과 발효홍삼에서는 모두 항알러지 및 항염증 효과가 있다고 사료된다. 그러나 LPS에 의한 B세포의 증식능에서 홍삼 $1\;{\mu}g/ml$은 증가효과를 발효홍삼에서는 $100\;{\mu}g/ml$에서 억제효과를 나타내었고, ConA에 의한 T세포의 증식능에서는 홍삼 $100\;{\mu}g/ml$에서 증가효과를 발효홍삼 $100\;{\mu}g/ml$에서는 억제효과를 나타냄으로써 림프구 증식능에 관한 실험에서는 두 추출물간에 상반된 효과를 나타내었다. HaCaT세포를 이용한 각질형성세포 증식능에서는 발효홍삼 1, $10\;{\mu}g/ml$에서만 효과를 나타내었다. 이러한 결과를 종합해 볼 때, 홍삼과 발효홍삼에 존재하는 성분량의 변화에 따라 그 효능에서 차이를 나타내고 있는 것으로 사료되며, 홍삼 및 발효홍삼의 고농도 $100\;{\mu}g/ml$에서는 저농도와는 다른 효과를 보이는 경향을 나타내고 있으므로 홍삼 및 발효홍삼의 사용에 있어 적절한 적응증과 주성분의 검증 및 유효 농도에 대한 연구가 더욱 필요하다고 판단된다.

1,2,3,4,6-Penta-O-galloyl-${\beta}$-D-glucose(PGG)는 오배자(Galla Rhois)의 gallotannin으로 항산화 효과, 항균 효과, 항알레르기 효과 등을 가지는 것으로 알려졌다. 알레르기성질환은 비만세포를 포함한 다양한 면역세포와 관련된 질환이다. 비만세포는 탈과립화에 의한 알레르기 매개성 물질(histamine 및 ${\beta}-hexosaminidase$)의 분비, T helper 2 type 사이토카인(IL-4) 분비 및 염증을 일으키는 매개체($TNF-{\alpha}$)의 증가를 통해 알레르기 반응에서 중요한 역할을 한다. 따라서 본 연구에서는 PGG가 phorbol 12-myristate 13-acetate(PMA)와 A23187로 비만세포인 RBL-2H3 세포에서 탈과립 그리고 Th2 type 및 염증성 사이토카인 생산에 미치는 영향을 조사하고, 관련 메커니즘에 대해 평가하였다. PGG는 PMA와 A23187 자극에 의한 탈과립 마커(histamine 및 ${\beta}-hexosaminidase$)의 분비를 억제하고, IL-4 및 $TNF-{\alpha}$와 같은 사이토카인의 분비를 억제하였다. 이러한 효과는 전사인자인 $NF-{\kappa}B$의 세포질에서 핵으로의 이동을 억제함으로써 나타나는 것으로 판단된다. 이러한 결과로부터 gallotannin의 하나인 PGG가 알레르기 반응을 현저히 저해하는 효과가 있는 것으로 나타나, 향후 알레르기성 질환을 예방, 개선 및 치료하는 데 유용한 물질로 사용될 가능성이 있을 것으로 생각된다.

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.
