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.

Potentilla chinensis Ser. (Rosaceae) has long been used for a remedy of diarrhea and inflammation in Korea. In this study, the anti-inflammatory effects of the Potentillae chinensis Herba water extract (PCX) was investigated in proteinase-activated receptor-2 (PAR2)-mediated rat paw edema. Paw edema was induced by injection of trypsin or trans-cinnamoyl-LIGRLO-$NH_2$ (tc-$NH_2$) into the hind paw of rats. PCX (10, 50, 100 and 200 mg/kg) was orally administered 1 h before the induction of inflammation. At doses of 50, 100 and 200 mg/kg, PCX showed significant inhibition on both change in paw volume and vascular permeability. PCX (100 mg/kg) significantly inhibited PAR2 agonists-induced myeloperoxidase (MPO) activity in paw tissue. These results indicate that PCX has an anti-inflammatory action in PAR2-mediated paw edema.

Curcumin, a dietary pigment responsible for the yellow color of curry, has been used for the treatment of inflammatory diseases and exhibits a variety of pharmacological effects such as anti- inflammatory, anti-tumor, anti-oxidant, and anti-viral activity. In order to examine the potency of the curcumin in inflammation we used carrageenan induced rat hind paw odema model. As curcumin is practically water insoluble, it is hypothesized that pharmacological activity of curcumin could be improved by enhancing its water solubility. Water soluble complexes of curcumin with cyclodextrins were prepared and screened for greater solubility. Pure curcumin 100 mg/kg body weight along with curcumin complexes equivalent to 100 mg/kg body weight of pure curcumin were tested for the anti-inflammatory activity in Wister rats male rats using carrageenan induced hind paw edema model and compared with that of the reference compound diclofenac sodium at a dose level of 10 mg/kg body weight. Results were statistically analyzed using ANOVA. All the treatment groups showed statistically significant anti-inflammatory activity compared with that of vehicle control and positive control.

Objective : The aim of this study is to investigate the anti-inflammatory effects of 15Hz electroacupuncture(EA) on carrageenan-injected rats. Inflammation was induced by an intraplantar injection of 1% carrageenan into the right hind paw. Methods : Bilateral EA stimulation with 15 Hz were delivered at those acupoints corresponding to Zusanli and Sanyinjiao in man via the needles for a total of 30 min duration in carrageenan-injected rats. Results: The developing edema was measured 30 minutes interval afer carrageenan injection and 15 Hz EA stimulation presented significant edema inhibition. Three hours after carrageenan injection, prostaglandin $E_2(PGE_2)$ and nitric oxide(NO) levels were measured. The 15Hz EA stimulation significantly inhibited $PGE_2$ and NO production in the right paw. The pro-inflammatory mRNA expression such as cyclooxygenases(COX)-2 and interleukin(IL)-$1{\beta}$ were slightly down-regulated by EA stimulation. The number of COX-2, IL-$1{\beta}$, tumor necrosis factor-${\alpha}$ immunoreactive cells were abundantly observed in paw edema. But these cells were decreased in nmber according to anti-edema effect of 15Hz EA. Conclusions: These results indicate that 15Hz EA stimulation have an alleviation action against carrageenan-induced edema and local inflammation.

Signal transducer and activator of transcription 4 (STAT4) is one of the important mediators in generating inflammation and immune responses. To address the role of Stat4 in carrageenan induced acute inflammation, we performed paw edema measurement and 7.4 k mouse cDNA microarray analysis in carrageenan induced acute inflammation in Stat4 knockout (-/-) mice. Male BALB/c (n=8) and Stat4 -/- (n=5) were used and paw edema was induced with injection of $30\;{\mu}L$ of 1% carrageenan into plantar surface of right hind paw. Next, we isolated the mRNA in mouse whole brain and analyzed cDNA microarray profiles for the changes of the brain expression in Stat4 -/- mice. Interestingly, the increase in paw volume of Stat4 -/- mice was reduced by about 30% as compared to that of wild type. The cDNA microarray analysis revealed the altered expressions of several cytokines (Tnf, Il6, and Il4) and pain-associated proteins (Ptgs2, Gabra6, and Gabbr1) in Stat4 -/- mice. Our results suggest that Stat4 may be related to the inhibitory responses on carrageenan induced acute inflammation.
