Evans blue content (b) and Myeloperoxidase activity (a) in gingivomucosal tissue was significantly increased by ligature compared to the contralateral side. Hypericum significantly reduced myeloperoxidase activity levels and Evans blue content (a, b respectively). Densitometry data are expressed as % of total tissue area. Data are means of mean ± s.e.m. from N = 10 rats for each group. *P < 0.01 vs. non-ligated. ° < b0.01 vs. ligated.
