Immunohistochemical detection of cyclooxygenase-2 (COX-2) in the epithelial cells (a), COX-2 activity (b), prostaglandin E2 (PGE2) levels (c), and N-acetyl-β-D-glucosaminidase (NAG) activity (d) in the scar tissue from rats untreated and treated with doxycycline hyclate (Dx). Cim: control of the immunohistochemical method (the primary antibody was omitted in the technique), C: control, , and . In the graphics, data are represented as mean and standard deviation.
