Delayed release particles from vascular endothelial growth factor for repairing spinal cord ischemic injury of rats.

OBJECTIVE To study the effect of delayed release particles from vascular endothelial growth factor (VEGF) on the reparation of ischemic injury of spinal cord in rats. METHODS The spinal cord ischemia model of rats was established. The delayed release particles from VEGF were injected via the intubation of spinal subarachnoid space. The rehabilitation was observed by the assessment of unfold claw reflection, space between toes, spinal evoked potential (SEP) and motor evoked potential (MEP). RESULTS VEGF prompted SEP and MEP appearance, improved the motor function of hind limbs. CONCLUSIONS VEGF can promote the rehabilitation of spinal cord ischemic injury of rats.
