MATERIAL and METHODS: The animals were divided into four groups as Group 1; control group, Group 2; trauma group, Group 3; AT III group and Group 4; Enoxaparin group. Severe trauma was performed by the weight dropping technique. These animals were killed 48 hours after injury. Histopathological and immunohistochemical analysis were performed. Specimens were graded for cell death, inflammation, hemorrhage and apoptosis.
RESULTS: The control group showed normal ultrastructure of brain tissue. Trauma produced obvious damage. 8 rats (80%) in the trauma group demonstrated minimal inflammation and grade 5 cell death. Trauma increased hemorrhage and apoptosis scores to statistically significant levels (p<0.001). Enoxaparin was found to reduce neuronal cell death but not as effectively as AT III. A statistically significant difference was observed between the AT III and Enoxaparin group according to inflammation grades. Significant antiapoptotic properties of AT III were observed while hemorrhage was more common in the Enoxaparin group.
CONCLUSION: Anticoagulants such as AT III and enoxaparin are promising drugs in the treatment of traumatic brain injuries.
