The nonprofit National Safety Council, or NSC, has been tracking fatality trends and providing estimates for almost 100 years. This year's preliminary estimates bring us some good news and some bad news.
After a spinal cord injury, blood flow is temporarily disrupted at the site of the injury. It resumes rapidly, however, and most doctors have assumed that blood flow then returns to near normal levels. A new study published in the May issue of Nature Medicine has demonstrated just the opposite -- spinal cord injuries lead to chronically poor blood flow and a lack of oxygen to the spinal cord's neuronal network. However, research showed that blocking a specific enzyme, and in turn pushing oxygen through the spinal cord improves the blood flow.
