In this study, we investigated whether Rosemary extract (RE) improved cognitive deficits in repetitive mild Traumatic brain injury (rmTBI) rats and its potential mechanisms. The present results showed that rmTBI caused cognitive deficits, such as increased latency to find platform and decreased time spent in target quadrant in Morris water maze (MWM). These behavioral alterations were accompanying with the increased neuronal degeneration and glial fibrillary acidic protein (GFAP)-positive cells, increased Reactive oxygen species (ROS) generation, decreased activity of Superoxide Dismutase (SOD), Glutathione Peroxidase (GPx) and Catalase (CAT), elevated protein level of IL-1 beta, IL-6 and TNF-alpha in hippocampus. Treatment with RE prevented these changes above. Our findings confirmed the effect of rosemary extract on improvement of cognitive deficits and suggested its mechanisms might be mediated by anti-oxidative and anti-inflammatory. Therefore, rosemary extract may be a potential treatment to improve cognitive deficits in rmTBI patients. (C) 2016 Elsevier Ireland Ltd. All rights reserved.
