Abstract

We have investigated the effects of WY14643, a potent peroxisome proliferator activator receptor- PPAR- agonist, in a rat model of ligature-induced periodontitis. Male Sprague-Dawley rats were lightly anaesthetized with pentobarbitone 35 mg-kg. Sterile, 2-0 black braided silk thread was placed around the cervix of the lower left first molar and knotted medially. Animals received WY14643 1 mg-kg i.p, daily for eight days. Eighths days after placement of the ligature, we evaluated several markers of inflammation such us 1 myeloperoxidase activity, 2 a cytokines and adhesion molecules expression, 3 NF-κB expression, 4 iNOS expression, 5 the nitration of tyrosine residues, 6 activation of the nuclear enzyme polyADP-ribose polymerase, 7 apoptosis, and 8 the degree of gingivomucosal tissues injury. Administration of WY14643 significantly decreased all of the parameters of inflammation as described above. These results demonstrate that WY14643 exerts an anti-inflammatory role during experimental periodontitis and is able to ameliorate the tissue damage.
