Introduction. The chronic obstructive pulmonary disease is a respiratory disease characterized by chronic airflow obstruction and inflammatory manifestation. Objective. To investigate the effect of low level laser therapy in the treatment of pulmonary inflammation. Methodology. We used 30 rats divided into three groups of ten animals: control group (received only room air), group COPD and COPD + laser (exposed to cigarette smoke for 45 days with group COPD + laser treated for 12 days with 904nm laser). For data analysis was performed histopathology. Results. The control group had normal air spaces with architectural distortion of the peripheral lung, COPD group showed a marked emphysema, areas of atelectasis and destruction of alveolar walls in the treated group there was a regression from mild to severe emphysema. Conclusion. Through the analysis performed pulmonary inflammation induced by cigarette can be proved, and the low level laser therapy was effective in reducing inflammation.
