Blast Overpressure-Induced Neuroinflammation and Axonal Injury in the Spinal Cord of Ferrets.

Summary: Explosions from combat can cause serious damage to a soldier's spinal cord, leading to long-lasting physical problems. To understand exactly how this happens, scientists studied ferrets exposed to blast waves. They checked how well the ferrets could walk and looked closely at their spinal cords after one day and again after one month. The blasts made it hard for the ferrets to walk normally, especially right after the explosion. When scientists looked at the spinal cords, they found swelling, inflammation, and damage to the nerve fibers in the neck area. This study shows that blast waves cause quick and lasting harm to the spinal cord, which could help doctors find new ways to treat injured soldiers in the future.
