Ultra-delicate surgery may offer hope to those paralyzed by spinal injuries.(Originated from Knight-Ridder Newspapers)
With a feat of ultra-delicate surgery considered impossible just a few years ago, researchers have partially repaired the severed spinal cords of 22 rats, enabling the once-paralyzed animals to move their legs and take a few stumbling steps.
This accomplishment, along with a handful of other recent advances, opens the possibility that doctors one day will be able to restore some feeling and movement to people paralyzed by spinal cord injuries.
Lars Olson and H. Cheng of Sweden's Karolinska Institute took a graft of threadlike nerve fibers from another part of the rats' bodies, attached them across the severed area, and coaxed them to start growing down the rat's spinal cords.
``This is the first time that anyone has shown regeneration in a completely severed spinal cord,'' neurosurgeon Wise Young of New York University Medical Center said.
While the finding is being announced in Friday's issue of the journal Science, rumors of the astonishing rat repair work have buzzed for weeks through the community of…
