Effect of pulsed radiofrequency treatment of the lumbosacral dorsal root on cytokines;

The release of SP and CA in the region deminated by dorsal root was examined by using the methods of cutting dorsal root, stimulating the distal end, dissociating the governed skin, collecting and determining the dermic perfusing liquid.

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;

Objective To explore the effect of silica on the structure and function of the calcium channel in dorsal root ganglion(DRG)of rat by analyzing the change of the high-voltage-activated(HVA)calcium current after silica exposure.

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 .
