Figure 2: Effect of HE-Bu obtained from Eugenia uniflora upon TNF-α (a) and IL-1β (b) production in infected mice serum. The mice, except the sham group, received vehicle, HE-Bu 75, 150. and 300 mg·kg−1 (p.o.) or dexamethasone (0.5 mg·kg−1 s.c.), which were administered 1 h before CLP surgery, and the cytokines levels were evaluated 6 h after onset. Each group represents the mean ± SEM of four to five animals. *, **, and *** indicated value versus CLP plus vehicle group; ## and ###, CLP plus vehicle versus sham. ANOVA followed by Bonferroni’s test. A false-operated group (sham) was also provided for this test.
