<B>July 27, 2009--</B>Fifteen minutes after researchers intentionally paralyzed this rat by dropping a weight on its back, they injected the rodent with Brilliant Blue G dye, a derivative of common food coloring Blue Number One. The dye reduced inflammation of the spinal cord, which allowed the rats to take clumsy steps—but not walk—within weeks, a new study says.</DIV></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://news.nationalgeographic.com/news/2009/07/photogalleries/blue-rats-food-dye-heals-pictures/index.html"><DIV>
In both rats and people, secondary inflammation following spinal cord trauma causes more lasting damage than the initial injury: Swelling sparks a small "stroke," which stops blood flow and eventually kills off the surrounding tissue.</DIV></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://news.nationalgeographic.com/news/2009/07/photogalleries/blue-rats-food-dye-heals-pictures/index.html"><DIV>
