Introduction: COPD is now a major challenge for public health, it is the fourth leading cause of death in the world and projected to be the third. Objective: To assess the anti-inflammatory action of the laser in the preservation of alveolar structure and decreases in neutrophils. Methods: We used five groups of eight animals: control group, group cannula; laser group, the COPD group (received papain instillation) and COPD + laser. For analysis of results were performed BAL and histopathological. Results: Results were submitted to analysis of variance (ANOVA). BAL showed a significant increase in the number of neutrophils in the COPD group compared to the control group and the COPD+laser group. In the histopathological analyses, COPD group showed a high degree of hyalinization, congestion and alveolar collapse, which was not found in other groups. Conclusion: Fotobiomodulation effects of laser proved effective in the prevention of lung emphysema.Downloads
