Roots of Erigeron annuus Attenuate Acute Inflammation as Mediated with the Inhibition of NF-κB-Associated Nitric Oxide and Prostaglandin E2 production
Figure 1
Inhibition of carrageenan-induced paw edema formation by EER. The EER was administered to rats at the oral dose of 0.3 or 1 g/kg/day. Then, paw edema was induced by subcutaneously injecting 1% solution of carrageenan dissolved in saline (0.1 mL per animal) into the hind paw. The swelling volume of the paw was measured at 1–4 h after carrageenan injection. Dexamethasone (Dex, 1 mg/kg, p.o.) was used as a positive control. Data represents the mean S.E.M. of five animals (significant as compared with carrageenan alone, ). For data points where error bars could not be seen, the standard error was subtended by the data point. EERs: extract of Erigeron annuus roots.
