Solanum melongena L. (Solanaceae) has anti-oxidant, analgesic, and hypolipidemic effects. We previously showed that Solanum melongena (SM) aqueous extract inhibits mast cell-mediated allergic reactions. The activation of protease-activated receptor-2 (PAR-2) induces acute inflammation in rat hindpaw. In the present study, we investigated the effects of the SM aqueous extract on mouse paw edema induced by PAR2 agonists. Trypsin or trans-cinnamoyl-LIGRLO-NH$_2$ (tc-NH$_2$), PAR-2 agonists, was injected into the hind paw of mice to induce paw edema. SM aqueous extract (1, 5, 10, and 100 mg/kg) was orally administered 1 hr before induction of paw edema. SM aqueous extract (5, 10, and 100 mg/kg) significantly inhibited both paw edema and vascular permeability in the dose-dependent manner. Furthermore, SM aqueous extract (10 mg/kg) significantly inhibited PAR-2 agonist-induced myeloperoxidase (MPO) activity and tumor necrosis factor (TNF)-$alpha$ expression in paw tissue compared to that of saline. These results suggest that SM aqueous extract may be useful for treatment of PAR-2-mediated inflammation.
