Inhibition of IgE-mediated anaphylactic reaction by Mentha arvensis in rats / 천식및알레르기

ABSTRACT

BACKGROUND: It has been reported that Mentha arvensis water extract (MAWE) inhibited systemic anaphylaxis and histamine release from the rat peritoneal mast cells (RPMC) by compound 48/80. OBJECTIVE AND METHOD: This study was undertaken to determine the inhibitory effects of immunoglobulin E (IgE)-mediated anaphylactic reaction by MAWE. This paper deals with an evaluation of the effect of MAWE on the anti-dinitrophenyl (DNP) IgE antibody induced anaphylactic reaction in rats. We also investigated the influence of MAWE on anti-DNP IgE antibody-induced tumor necrosis factor-alpha (TNF-alpha) production. RESULTS: MAWE inhibited passive cutaneous anaphylaxis (PCA) when intravenously, intrap- eritoneally, and orally administered. MAWE dose-dependently inhibited histamine release from RPMC activated by anti-DNP IgE antibody. Moreover, MAWE had an inhibitory effect on anti-DNP IgE antibody induced TNF-alphaproduction from RPMC. CONCLUSION: These results suggest that MAWE inhibits the IgE-mediated anaphylactic reaction in rats.
