  • 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.

  • Samul-Tang (SMT) has been used for nourishing of the blood, hematopoiesis as a herbal medicine history. The purpose of this study is to find out anti-allergic inflammatory reaction of SMT. To clarify the mechanism, the effect of SMT on vascular permeability of rat cutaneous tissue and histamine and cytokines (IL-6, IL-8, TNF-${\alpha}$) release from mast cells were observed. The results are the pretreatment with SMT significantly decreased the compound 48/80-induced degranulation and histamine release from RPMC, SMT also inhibited the anti-DNP lgE-induced increment of vascular permeability of rat cutaneous tissue. SMT significantly reduced the PMA plus A23187-induced increment of expression of IL-6, IL-8, and TNF-${\alpha}$ in HMC-1 Cell. The Present study provide evidence that SMT inhibits mast cell-derived inflammatory allergic reactions by blocking histamine release and pro-inflammatory cytokine expression, and suggest the mechanisms of action. Furthermore, in vivo and in vitro anti-allergic effect of SMT suggests a possible therapeutic application of this agent in inflammatory allergic diseases.

  • This study is aimed at determining whether graviola (Annona muricata) beneficially influences immunoglobulin (Ig) E-mediated allergic reactions in human mast cells (LUVA cells). To examine the anti-allergic effect of graviola leaf extract (GLE), we treated antigen/IgE sensitized mast cells with extracts of various concentrations. In this study, the results of the in vitro model of IgE-mediated mast cell degranulation showed that GLE significantly inhibited the release of histamine, β-hexosaminidase, TNF-α, IL-4 and IL-6 in LUVA cells. Pretreatment with GLE suppressed the phosphorylation of antigen-induced Lyn and Syk, thus suppressing the downstream MAPKs pathways. The above results indicate GLE could suppress mast cell activation and allergic responses. Accordingly, it can be supported that GLE has the potential to be used as functional cosmetic material.

  • The effect of aqueous extract of Stachys riederi var. japonica Miq. (Labiatae) (SRAE) on the immediate-type allergic reactions was investigated. SRAE was found to exhibit a inhibitory activity on the compound 48/80-induced systemic anaphylaxis in mice. SRAE inhibited the plasma histamine release induced by compound 48/80 in mice. In addition, SRAE also inhibited the passive cutaneous anaphylaxis reaction induced by IgE/anti-IgE in mice. The effect of SRAE on the histamine release from rat peritoneal mast cells (RPMC) was studied. SRAE inhibited the histamine release induced by compound 48/80 in RPMC. To clarify the mechanism of these inhibiting reactions, we investigated the effects of SRAE on cyclic AMP (cAMP). The level of cAMP in human leukemia cell line, HMC-1, when SRAE (1 mg/ml) was added, significantly increased compared with that of basal cells. These results indicate that SRAE may be beneficial in the treatment of immediate-type allergic reaction.

  • Objective: In this study, we investigated the protective effect of rhododendron mucronulatum extract (RME) on allergic reactions and inflammation. Methods: The effect of RME was determined using ELISA and RT-PCR in RBL-2H3 mast cells and RAW 264.7 macrophage cells. We determined cell viability, β-hexosaminidase release, and the synthesis of IL-4 and TNF-α in RBL-2H3 cells. In addition, we determined NO from RAW 264.7 and the gene expression of IL-1β, iNOS, IL-6, TNF-α, and IL-10. Results: RME inhibited β-hexosaminidase release and synthesis of IL-4 and TNF-α in RBL-2H3 by the anti-DNP IgE plus DNP-HSA stimulation. In addition, RME inhibited the production of NO and the gene expression of IL-1β, iNOS, IL-6, and TNF-α in LPS-stimulated RAW 264.7 cells. Conclusion: From these results, we concluded that RME possesses anti-allergic activity and anti-inflammatory activity due to the inhibition of mast cells and macrophage function.
