DOI : 10.30621/jbachs.2018.432 Objectives: The effects of ozone treatment on direct mechanical injury and the inflammation secondary to the injury resulting from blunt thoracic trauma were evaluated with the histopathological results obtained in our study.

Patients and Methods: 24 adult male Wistar albino rats of the same colony with an average weight of 200-250 gr were used in our study. The rats were divided into 3 groups. First group were anaesthetized with ketamine HCl/xylazine. Second group were given contusion with isolated unilateral lung contusion. Third group were given 30 μgr/ml ozone at a dose of 1.1mg/kg intrarectally after the contusion for five days. Four different parameters; atelectasis, parenchymal inflammation, perivascular mononuclear inflammation and bronchial injury, were used in histopathological evaluation and all parameters were scaled.

Results: Cell concentration, perivascular mononuclear inflammation and leukocyte infiltration were significantly higher in the lung tissues of all the rats in the trauma group compared to the anesthesia group. However, when the control, trauma and ozone groups were compared, there was no significant difference in terms of alveolar edema and bronchial injury. Similarly, among subgroubs of trauma and ozone groups, there was not a statistical significance in terms of histopathological data.

Conclusion: When inflammatory stages and cell distribution were compared between the study groups, advanced acute inflammatory changes were found on the fifth day of inflammation in both contusion groups and no significant difference was observed in terms of inflammatory response pattern. Consequently, no positive effect of ozone treatment was shown on the acute and subacute inflammatory response in decreasing the primary and secondary injury caused by the trauma.
