Effect of the treatment with 16-hydroxy betulinic acid (50, 100 mg/kg) and Phenylbutazone as control (100 mg/kg) on paw edema induced by intradermal injection of carrageenan (1% 0.1 ml) in rats. Zero (time zero) corresponds to baseline measurement of animals performed 24 h before the test. Each group represents the mean of 5 animals, and the vertical lines indicate the SEM. ^∗P< 0.05 and ^∗∗P < 0.01 compared with control group.
