The mast cell plays a pivotal role in initiating allergic response by secreting intracytoplasmic granular mediators such as histamine. Magnoliae flos has been used for treatment of allergic disease in Korea. However, its effect in experimental models remains unknown. The present report describes an inhibitory effect of Magnoliae flos on mast cell-mediated immediate-type allergic reactions. Topical application of compound 48/80 can induce an ear swelling response in normal($WBB6F_1-+/+$) mice but not in the congenic mast cell-deficient $WBB6F_1-W/W^v$ mice. Magnoliae flos inhibited concentration-dependently mast cell-dependent ear swelling response induced by compound 48/80 by topical application. Magnoliae flos inhibited concentration-dependently passive cutaneous anaphylaxis induced by anti-dinitrophenyl (DNP) IgE in rats by topical application. Magnoliae flos also inhibited concentration-dependently the histamine release from the rat peritoneal mast cells by compound 48/80 or anti-DNP IgE. Moreover, Magnoliae flos had a significant inhibitory effect on compound 48/80-induced systemic anaphylactic reaction. These results indicate that Magnoliae flos inhibits immediate-type allergic reactions by inhibition of mast cell degranulation in vivo and in vitro.

The immature fruits of Poncirus trifoliata L. or Ponciri fructus (PF), well known as 'Jisil' in Korea, have been used against allergic diseases for generations, and still occupy an important place in traditional Oriental medicine. Anti-allergic effects of this fruit have been investigated in a few experimental models. Immunoglobulin E (IgE) is the principal immunoglobulin involved in immediate hypersensitivities and chronic allergic diseases. The effect of an aqueous extract of PF on in vivo and in vitro IgE production was investigated. PF dose-dependently inhibited the active systemic anaphylaxis and serum IgE production induced by immunization with ovalbumin, Bordetelia pertussis toxin and aluminum hydroxide gel. PF strongly inhibited interleukin 4 (IL-4)-dependent IgE production by lipopolysaccharide-stimulated murine whole spleen cells. In the case of U266 human IgE-bearing B cells, Ponciri fructus also showed an inhibitory effect on the IgE production. On the other hand, mast cell hyperplasia can be causally related with chronic inflammation. Stem cell factor (SCF), the ligand of the c-kit protooncogene product, is a major regulator and ohernoattractant of mast cells. Ponciri fiuctus (1 mg/mL) significantly inhibited the SCF-induced migration of rat peritoneal mast cells (RPMCs). RPMCs exposed to SCF (50 ng/mL) resulted in a drastic shape change with a polarized morphology while the cells exposed to Ponciri fructus (1 mg/mL) remained resting, with little or no shape alteration. The drastic morphological alteration and distribution of polymerized actin were blocked by pretreatment with Ponciri fructus. In addition, Ponciri fructus inhibited both TNF-alpha and IL-6 secretion from RPMCs stimulated with SCF. These results suggest that Ponciri fructus has an anti-allergic activity by inhibition of IgE production from B cells. These findings also provide evidence that Ponciri fructu inhibits chemotactic response and inflammatory cytokines secretion to SCF in mast cells.

유색미 겨 추출물이 염증반응에 미치는 효과를 호중구 세포주 및 비만세포가 분비하는 염증매개물질인 histamine과 ${\beta}-hexosaminidase$의 분비 및 염증 cytokine 생성에 대한 억제활성을 측정하여 평가하였다. 호중구 세포주인 RBL-2H3 세포와 rat에서 분리 추출한 복강 비만세포(RPMC, peritoneal mast cell)를 이용하여 histamine과 ${\beta}-hexosaminidase$ 분비에 대한 억제활성을 조사한 결과, 일반미 겨 추출물은 RBL-2H3 세포에서 염증매개물질들의 분비량을 증가시킨 반면, 유색미 겨 추출물은 이들의 분비를 억제하였다(histamine 10.19% 억제, ${\beta}-hexosaminidase$ 110.03% 억제). RPMC에서는 유색미가 histamine과 ${\beta}-hexosaminidase$의 분비를 일반미보다 각각 8배와 3배나 높게 억제하는 것으로 나타났다. 염증관련 cytokine으로서 $IL-1{\beta},\;TNF-{\alpha}$ 및 IL-6의 발현을 RT-PCR로 측정한 결과, 유색미가 일반미 보다 $TNF-{\alpha},\;IL-1{\beta}$ 및 IL-6의 발현을 억제하는 효과가 우수하였다. ELISA를 이용하여 cytokine의 분비량을 측정한 실험에서도 유색미가 일반미보다 $TNF-{\alpha},\;IL-1{\beta}$ 및 IL-6의 분비를 효과적으로 억제하였다. 이상의 결과는 유색미가 염증반응의 원인 물질인 histamine과 ${\beta}-hexosaminidase$의 분비에 대한 억제효과 뿐 아니라, 염증 cytokine의 발현을 저해하는 효과도 일반미보다 우수하다는 사실을 보여주었다.

02PS15 extracts (BuOH, $H_2O$, and crude extracts) significantly inhibited IL-4 and IL-6 secretion from the phytohemagglutinin (PHA)-plus phorbol 12-myristate 13-acetate (PMA)-induced peripheral blood mononuclear cleas (P<0.05). 02PS15 extracts (BuOH and crude extracts) also significantly inhibited the histamine release from rat peritoneal mast cells (P<0.05). Significant reduced levels (P<0.05) of PMA- and A23187-induced IL-8 were observed in the human mast cell line, HMC-1, with O2PS15 extracts (BuOH and crude extracts). 02PS15 extracts (BuOH and crude extract) downregulated the expression of IL-6 and IL-8 in the activated HMC-1. These results suggest that O2PS15 has the inhibitory effect of atopic allergic reaction anil this might be useful for clinical application to treat several allergic diseases such as atopic dermatitis.

The purpose of this research was to investigate the effects of Kamihyungbangjihwang-tang (KHT) on immediate-type allergic reaction. KHT was composed of hyungbangjihwangtang (HJT) and Rubus coreanus Miquel (RC) and Aspalathus linear is (AL). KHT and HJT (500 mg/kg) inhibited the systemic anaphylaxis induced by compound 48/80 and inhibited the passive cutaneous anaphylaxis (PCA) induced by anti-dinitrophenyl (DNP)-IgE and DNP-human serum albumin (HSA) in vivo. In addition, KHT, HJT, RC and AL inhibited the release of histamine and increased the release of cAMP from rat peritoneal mast cells. The anti-allergic action of KHT was more potent than those of HJT. These results indicate that KHT may be useful for the prevention and treatment of type I allergy related disease via inhibition of histamine release from mast cells.

The purpose of this research was to investigate the effects of Kwakhyangjeonggisan (KJS) on the anti-allergic action. In the present study, we examined the effect of KJS on type I and type IV allergic reaction. KJS inhibited the systemic anaphylaxis induced by compound 48/80 and platelet activating factor (PAF), and inhibited the passive cutaneous anaphylaxis (PCA) induced by anti-dinitrophenyl (DNP)-IgE and DNP-human serum albumin (HSA) in vivo. In addition, KJS dose-dependently inhibited the release of histamine from peritoneal mast cells in rat. Also, KJS inhibited the delayed type hypersensitivity (DTH) induced by SRBC and the contact dermatitis induced by dinitrofluorobenzene (DNFB). KJS inhibited the proliferation of splenocytes, the subpopulation of B220+ cells and CD4+CD8-(Th) cells in splenocytes and the production of γ-interferon in serum and splenocytes. These findings suggest that KJS prevented the type I allergy by the inhibition of histamine release from mast cells and the type IV allergy by the inhibition of γ-interferon production and B lymphocytes subpopulation. These results indicate that KJS may be useful for the prevention and treatment of type I and type IV allergy related disease.

We analyzed the effect on the expression of various cytokines, and IgE from mast cells and the underlying molecular mechanisms of WONGAM and SINWONGAM in presented models. Results : WONGAM and SINWONGAM showed the inhibitory effect on the histamine release from rat peritoneal mast cells or human mast cells without cytotoxicity. WONGAM and SINWONGAM blocked anaphylactic shock and decreased the IgE production. Furthermore, WONGAM and SINWONGAM inhibited the productions of TNF-α and IL-6 in compound 48/80-induced anaphylaxis mice model. Conclusion : These results indicated that WONGAM and SINWONGAM would have protect effect on allergic responses through the inhibition of allergic mediators and pro-inflammatory cytokines. This study may facilitate the development on Glycyrrhiza new varieties for allergy.

Objectives: The root and stem of Sinomenium acutum has been used for treatment of arthritis and neuralgia in oriental medicine. To find new substances of the anti-anaphylactic drugs, we studied Sinomenium acutum. Methods: To investigate the effect of this plant, the effect on anaphylactic reaction, plasma histamine level, and tumor necrosis $factor-{\alpha}-(TNF-{\alpha})$ production were measured after the aqueous extract of Sinomenium acutum stem (SSAE) was administrated to mice and rats. Results: The SSAE (0.1 to 1000 mg/kg) dose-dependently inhibited systemic anaphylactic reaction induced by compound 48/80 in mice. Especially, SSAE reduced compound 48/80-induced anaphylactic reaction with 50% at the dose of 1000 mg/kg. SSAE (100 to 1000 mg/kg) also significantly inhibited local anaphylactic reaction activated by anti-dinitrophenyl (DNP) IgE. When mice were pretreated with SSAE at a concentration ranging from 0.1 to 1000 mg/kg, the plasma histamine levels were reduced in a dose-dependent manner. SSAE (1 to 1000 g/ml) dose-dependently inhibited histamine release from the rat peritoneal mast cells (RPMCs) activated by compound 48/80 or anti-DNP IgE. The level of cAMP in RPMCs, when SSAE was added, increased compared with that of a normal control. In addition, SSAE (0.1 g/ml) had a significant inhibitory effect on anti-DNP IgE-induced $TNF-{\alpha}$ production. Conclusions: These results indicate that SSAE inhibits mast cell-mediated anaphylactic reactions and $TNF-{\alpha}$ production from mast cells.

The inhibitory effects of 25 polyphenols against in vitro allergic reactions were compared using biochemical and cell assays. Three polyphenols including curcumin, gallic acid, and quercetin suppressed the release of $\beta$-hexosaminidase from ionophore A23187-stimulated RBL-2H3 cells more effectively (>50% inhibition at $100{\mu}M$ concentration). They were found to have potencies in suppressing the release of histamine not only from ionophore A23187-, but also from immunoglobulin E (IgE)-stimulated RBL-2H3 cells. Moreover, such suppressive effects of the three polyphenols were also observed in A23187 plus PMA-costimulated rat peritoneal mast cells. The extent of inhibition were quantified as the respective polyphenol concentration that inhibit 50% ($IC_{50}$) of $\beta$-hexosaminidase or histamine release, showing an inhibition tendency with decreasing order of curcumin>gallic acid>quercetin. Down-regulation of $Ca^{2+}$ influx was suggested as the cause of the inhibition of $\beta$-hexosaminidase and histamine releases in these cells. The immune process inhibition was confirmed by the observed reduction in the gene expressions and release of pro-inflammatory cytokine tumor necrosis factor (TNF)-$\alpha$, interleukin (IL)-$1\beta$, and IL-4, due probably to antioxidant activity of the polyphenols. These findings illustrate that curcumin, gallic acid, and quercetin may be beneficial against allergic inflammatory diseases.
