Abstract
In a previous experiment using TNF inhibition in the rat it was accidentally found that adhesion and scar formation was reduced compared to previous experience. Wound and bone healing also seemed enhanced. The present study was conducted to assess if this observation could be verified in a controlled setting using a standardized laminectomy in the rat. Five rats received doxycycline and five other rats received saline and served as control. Macroscopic blinded evaluation 1 week after the laminectomy revealed that adhesion and scar formation was less in doxycycline-treated animals than in control animals. Wound and bone healing was found to be better in doxycycline-treated animals. The mechanisms for the observed effects cannot be fully understood but the data indicate that further research may lead to opportunities to design pharmacological modalities to reduce adhesion and scar formation, maybe in combination with suitable barriers.
