Abstract
We investigated the effect of aqueous extract of Vitex rotundifolia (L.) (Verbenaceae) fruits (VRFE) on the immediate-type allergic reactions in vivo and in vitro. VRFE (10-4-1.0 g/kg) dose-dependently inhibited systemic allergic reaction induced by compound 48/80. When VRFE was employed in a systemic allergic reaction test, the plasma histamine levels were reduced in a dose-dependent manner. VRFE (5 x 10-1 and 1.0 g/kg) inhibited passive cutaneous anaphylaxis activated by anti-dinitrophenyl (DNP) IgE. VRFE (10- 3-1.0 mg/ml) also dose-dependently inhibited the histamine release from the rat peritoneal mast cells (RPMC) by compound 48/80 or anti-DNP IgE. Moreover, VRFE (10-3 mg/ml) had a significant inhibitory effect on anti-DNP IgE- induced tumor necrosis factor-α production from RPMC. These results suggest that VRFE may be beneficial in the regulation of immediate-type allergic reaction. (C) 2000 Elsevier Science Ireland Ltd.
