Figure 4. Western blot analysis of COX-1 and COX-2 in the late phase of the paw edema.

Expression of COX-1 (A) and COX-2 (B) were evaluated in paws homogenates obtained from mice treated with perthamide C, vehicle or saline at 24, 48, 72, 96 h following λ-carrageenan injection. (n = 4 paws for each treatment and time point) ^*P<0.05 ^**P<0.01 vs saline. Image is representative of three separate experiments.
