Effects of taraxasterol on cotton pellet-induced rat granuloma. The sterile cotton pellets were implanted by a single needle incision into both axillae regions of rats. Then the rats were divided into five groups (n=10 for each group): taraxasterol groups (2.5, 5, 10 mg/kg, respectively), control group (0.5% CMC-Na), and positive group (2.5 mg/kg DXM). On day 8, the wet cotton pellets were carefully dissected and the granuloma formation was measured by the increase in dry weight of the pellets. Data represent means ± SEMs. * P<0.05, ** P<0.01 vs. control group.
