[Characteristics of the effect of a constant electromagnetic field on reparative processes in spinal cord injuries].

In 171 white rats the spinal cord was completely sectioned in the upper thoracic region. In 46 control rats an early crude spinal cord scar was identified which precluded the growth of nervous fibers. On the contrary, in animals exposed to constant magnetic field a smooth spinal cord scar was found with collaterals of anterior spinal arteria, recrease of the destruction zone and nervous fiber growth across the scar, This resulted in restored hind paw motility by 56 +/- 4.
