Figure 1

The motor function evaluated by Tarlov Scoring System after 72-hour reperfusion. The spinal ischemia-reperfusion significantly impacted the motor function, and a high score was seen in animals with spinal ischemia + saline; but BYHWD administration and roscovitine pre-treatment greatly improved the motor function. The score was higher in the group with roscovitine than that in the group with BYHWD, but there were no significant differences between the groups. **: P < 0.01 vs. Control group. *#: P < 0.05 vs. SI + Saline. SI + Saline: Spinal ischemia + Saline. SI + BYHWD: Spinal ischemia + BYHWD. SI + R: Spinal ischemia + Roscovitine.
