The Effect of Safflower Yellow on Spinal Cord Ischemia Reperfusion Injury in Rabbits
The neurons of spinal cord anterior horn were assessed by HE staining and viewed at the magnification of 200 times. There were numerous normal neurons without morphological change in the control (Cont.) group (a). Neuronal structural changes appeared in group (b), such as neuronal pyknosis, light staining tigroid body, and nucleus atrophy. The percentage of normal neurons was higher in the group (c) as compared to that in the group, and only slight edema was observed in group. Bar graph (d) showed the comparison for the ratio of normal motoneurons in spinal cord anterior horn between group and group, and * indicated comparison with the other groups, . NN-index: normal to total neuron number ratio.
