Completely paralyzed dog could walk through two weeks after it had been restored to its spinal cord.

However, during the flood of four rats, which were injected with polyethylene glycol, were killed. Another one rescued rats, which was injection, was recovered the ability to walk.
In another experiment conducted by Korean scientists, was spinal cord injury in 16 mice. Half of them were made by injection of polyethylene glycol. Five of the eight mice showed signs of recovery movements. The remaining three died.
