Spinal cord injury causes neuron nerve fiber loss. The aim of this study was to investigate the neuroprotective, inflammatory and angiogenetic effects of melatonin on rat spinal cord injury (SCI). For spinal cord injury, a standard weight reduction method was used that caused moderate severity of injury (100 g / cm force) Tat10 Melatonin (10 mg/kg intraperitoneally ) was administered for 10 days after trauma. Each group consisted of 10 animals. of these, six were used for biochemical and four were used for th e evaluation of histological analysis. Spinal cord samples were taken for histological examination or determination of malondiald ehyde (MDA) and glutathione (GSH) levels, myeloperoxidase (MPO) activity. Spinal cord injury and melatonin treated group were compared. Melatonin administration in spinal cord injury increased the activity of glial cells in the radial and funicular cells and epen dymal cells and increased the activity of glial cells and also showed a positive ef fect on inflammation and vascular endothelial cells in s ynaptic connections in the nerve fibers undergoing spinal injury endothelial degeneration It is thought that it can regulate the degenerative effect which is caused by both the inflammatory effect and the angiogenic effect which will have a positive effect on the neural connection.
