Neuropathological and neuroprotective features of vitamin B12 on the dorsal spinal ganglion of rats after the experimental crush of sciatic nerve: an experimental study.

Background: Spinal motoneuron neuroprotection by vitamin B12 was previously reported; the present study was carried out to evaluate neuroprotectivity in the dorsal root ganglion sensory neuron.

Methods: In present study thirty-six Wister-Albino rats (aged 8-9 weeks and weighing 200-250 g) were tested. The animals were randomly divided into 6 groups which every group contained 6 rats.
