Abstract
The effects of Arctii fructus extract on allegenic inflammation were investigated using in vivo and in vitro test models. Firstly, the cytotoxicity of Arctii fructus extract was validated using MTT assay. As a result, Arctii fructus extract showed no cytotoxic potential, while SDS, a positive control, revealed strong cytotoxic effect. In LLNA assay, Arctii fructus extract showed no skin allergenicity. Next, the anti-allergic actions of Arctii fructus extract were evaluated using rodent experimental models. The oral, intraperitoneal and intradermal administration of Arctii fructus extract significantly inhibited the compound 48/80-induced vascular permeability documented by Evans blue extravasation. In addition, Arctii fructus extract showed potent inhibitory effect on passive cutaneous anaphylaxis activated by anti-dinitrophenyl (DNP) IgE when orally administered. In an in vitro study, Arctii fructus extract revealed to possess inhibitory potential on the compound 48/80-induced histamine release from rat peritoneal mast cells. Moreover, Arctii fructus extract inhibited the IL-4 and TNF-
