Purpose: To investigate the role of Rosmarinic acid (RA) in the prevention of traumatic brain inand the immunohistochemical analysis of IBA-1 and GFAP expressions.Methods: Healthy male rats were randomly divided into 3 groups consisting of 10 rats. Groups were as follows; control group, traumatic brain injury (TBI) group, and TBI+RA group. After traumatic brain injury, blood samples were taken from the animals and analyzed with various biochemical markers. And then IBA-1 and GFAP expressions were evaluated immunohistochemically.Results: Significant results were obtained in all biochemical parameters between groupImmunohistochemical sections showed IBA-1 not only in microglia and macrophage activity but alsin degenerative neurons in blood vessel endothelial cells. However, GFAP reaction and post-traumatirosmarinic acid administration showed positive expression in astrocytes with regular structure arounthe blood vessel.Conclusion: Rosmarinic acid in blood vessel endothelial cells showed that preserving the integrity of astrocytic structure in the blood brain barrier may be an important antioxidant.
