HE (haematoxylin-eosin) staining of spinal cord sections at the 2 days after operation. a No sign of neurnal damage was observed in the sham group. b Decrease of the cell volume of neuron and karyopyknosis were observed in group 3. c Reduction of the number of neuron and vacuolation of grey matter were observed in Group 4. d Apoptotic and necrotic motoneurons in the ventral horn were observed in group 5
