[The changes of NT-4 expression in spared root ganglion and spinal cord following partial dorsal root rhizotomy].

Objective: This study was conducted to detect the expression levels of NT-4 in the spared dorsal root ganglia (DRG, L6) on the operated side and un-operated side, in the spinal lamina II (L3, L5, L6) and Clarke's nucleus (L3) of the normal adult cats and the cats submitted to partial dorsal rhizotomy. The aim was to illuminate the temporospatial changes of NT-4 expression and its possible relation to spinal cord plasticity.

Methods: Fifteen male adult cats were divided into three groups.
