ETHNOPHARMACOLOGICAL RELEVANCE: KOB03 is a polyherbal medicine consisting of five different herbs and has commonly been used for the treatment of various allergic diseases. However, its precise anti-allergic effect and mechanism remain unknown.
AIM OF THE STUDY: The aim of this study was to investigate the effect of KOB03 on allergic responses through the regulation of mast-cell mediated allergic inflammation.
MATERIALS AND METHODS: To determine the effect of KOB03 on mast cell-mediated allergic reactions, we investigated the parameter changes of in vivo models such as compound 48/80-induced systemic anaphylaxis and ovalbumin (OVA)-induced allergic rhinitis, and the release of allergic inflammatory mediators such as histamine, immunoglobulin (Ig) E, and inflammatory cytokines via the MAPKs and NF-kappaB pathways.
RESULTS: The oral administration of KOB03 at doses of 100 and 200mg/kg inhibited histamine release and mortality in compound 48/80-induced anaphylactic rats. KOB03 also improved rhinitis symptoms, inhibited the histopathological changes of nasal mucosa, and decreased the serum levels of histamine, OVA-specific IgE and TNF-α in OVA-induced allergic rhinitis in mice. In vitro, KOB03 suppressed compound 48/80-induced histamine release by blocking mast cell degranulation. In addition, KOB03 inhibited the production of inflammatory cytokines such as TNF-α, IL-1β, IL-6 and IL-8 in PMA/A23187-stimulated HMC-1 mast cells by suppressing their gene expression and blocking the ERK1/2 and p38 MAPK and NF-κB pathways.
CONCLUSIONS: These results suggest that KOB03 has an anti-allergic effect by modulating mast cell-mediated allergic responses in allergic rhinitis.
