Abstract

Several studies demonstrate the involvement of glial cells and neurotrophins in neuropathic pain by modulating the response nociceptive. However, these mechanisms are poorly understood when discussed in the dorsal root ganglia of the spinal cord (DRG). In recent years increased studies related to the development of techniques for the treatment of neuropathic pain. Pain is characterized by spontaneous burning pain accompanied by allodynia and hyperalgesia. The technique of Neural Mobilization is non-invasive and clinically proven to be effective in reducing sensitivity to pain and therefore improving the quality of life of patients. It should be noted that this technique has been adapted to rats in our laboratory and is best described in the methodology of this project. Our aim is to characterize, through the methods of immunohistochemistry the involvement of satellite cells, GFAP (glial fibrillary acidic protein), and NGF (growth factor neural) in DRG of rats with chronic constrictive injury (CCI) of the sciatic nerve and treated with neural mobilization.(AU)
