Relative expression of COX-2 mRNA (a), mPGES-1 mRNA (b), and PGIS mRNA (c) in rat hind paw. Carrageenan (Car) injection (filled bars) elevated COX-2 mRNA and mPGES-1 mRNA levels compared to saline (Sal) injection (open bars) though the elevations were not statistically significant by t-test except for COX-2 and PGIS in BEL-treated groups. BEL did not significantly influence COX-2 mRNA, mPGES-1 mRNA, or PGIS mRNA levels.
