Figure 2.
Mikania laevigata extract (MLE) decreases neutrophil migration to the gingival tissue. In order to estimate the relative numbers of infiltrating neutrophils in the gingival tissue, myeloperoxidase (MPO) activity present in the gingival tissue homogenates was measured. Results are shown as mean MPO activity ± standard deviation. # p<0.05 compared with control animals; * p<0.05 compared with ligature-induced periodontitis treated with vehicle (ANOVA followed by Bonferroni's test)
