Morphological alterations induced by didanosine in cultured dorsal root ganglion nrurons;

Expression of three distinct families of calcium-activated chloride channel genes in the mouse dorsal root ganglion;

Effect of nucleus pulposus allografted into epidural space on the expressions of TNF-α and IL-1 in rat′s dorsal root ganglion neurons;

The expression of the NGF receptor p75 in lumbar dorsal root ganglia and bladder of streptozocin-induced diabetic rats;

Effect of gabapentin on sympathetic sprouting of the dorsal root ganglia in the spinal nerve ligation model rats;

Change of expression of vesicular glutamate transporter 1 in the lumbar spinal cord,dorsal root ganglia and nerve stump distal to ligation after complete ligation of the unilateral sciatic nerve;

To study the changes of the expression of calcitonin gene-related peptide (CGRP) in the spinal cord and dorsal root ganglia (DRGs) after dorsal rhizotomy, 25 adult Sprague-Dawley rats were randomly divided into normal group, sham-operated group and L4、5 dorsal rhizotomy group, and the experimental group was further divided into 3 d, 7 d and 14 d groups according to the survival time, respectively.

Objective To investigate the experssion of calcitonin gene-related peptide(CGRP) in dorsal root ganglion (DRG) and spinal cord of rats after sciatic nerve ligation.

：The purpose of this study is explored different neur otrophic effects of glial-derived neurotrophic factor (GDNF) on survival ,viabi lity and neurite outgrowth of injured DRG by KA-induced,so primarily cultured DRG neurons were dissociated from neonatal rats in N1 serum-free medium,inju rious model was set up by the addition of KA into the cultures in vitro .
