Figure 6. Figure 6: Effect of EEB of H. umbrosa on leukocyte migration into the peritoneal cavity induced by carrageenan in mice. Groups of rats were pre-treated with vehicle (control), dexamethasone (Dexa, 2 mg/kg, s.c.) or EEB (100, 200 and 400 mg/kg) 60 min before carrageenan (500 µg/cavity, 500 µL, i.p.)-induced peritonitis. Cell counts were performed at the time 4 h after the injection of carrageenan. Each value represents the mean ± S.E.M. **p < 0.01 or ***p < 0.001 related to control group. ANOVA followed by Tukey's test.
