Aim:TBI has two distinct phases: primary and secondary injury. Many agents have been used to prevent secondary injury. Oleocanthal (OC) has anti-inflammatory and antioxidant properties similar nonsteroidal anti-inflammatory drug. We evaluated the neuroprotective effects of OC in a rat model of TBI.Material and Methods:Twenty-six adult male, Wistar albino rats were used. The rats were divided into 4 groups. group 1, sham (n = 5). group 2, trauma (n = 5): Rats were treated with 10 mg/kg saline intraperitoneally (IP) twice a day. Groups 3 and 4, rats were treated with 10 (group 3, n = 8) or 30 (group 4, n = 8) mg/kg OC IP twice a day. For each group brain samples were collected 72 h after injury. Brain samples and blood were evaluated with histopathological and biochemical methods.Results:Histopathological evaluation revealed a significant difference between group 2 and group 4. Biochemical findings demonstrated that, oxidative stress index was the highest in group 2 and was the lowest in the group 4. Conclusion:Results indicated that OC has a protective effect on neural cells after TBI. This effect is achieved by reducing oxidative stress and apoptosis.
