OBJECTIVES: This study is aimed to determine the effect of ozone therapy in neonatal rats with experimentally induced hypoxic ischemic brain injury (HIBI). METHODS: The study included 7-d-old male Wistar rats that were randomized to the sham, control, ozone 1, and ozone 2 groups. All rats except those in the sham group were kept in a hypoxia chamber, and then the rats in the control group were given 0.5 mL of saline. Those in the ozone 1 group were given ozone 1 mg kg-1 intraperitoneally, and those in the ozone 2 group were given ozone 2 mg kg-1 intraperitoneally. RESULTS: There were significantly fewer apoptotic neurons in the right hemispheres of the rats in the ozone 1 and ozone 2 groups than in the control group (p < 0.001 and p < 0.001, respectively). There were significantly fewer apoptotic neurons in the right hemispheres of the rats in the ozone 2 group than in the ozone 1 group (p < 0.001). Morris Water Maze (MWM) test results were similar in the ozone 2 and sham groups. CONCLUSIONS: The present study's findings show that ozone therapy reduced neuronal apoptosis and improved cognitive function in neonatal rats with experimentally induced HIBI (Tab. 2, Ref. 30).
