| Have you ever wished you could not feel pain? There are people in the world with this ability. They do not know when they are hurting. Last year,Nature magazine published a report about six children who have never suffered pain.The research team found the children after hearing about a boy who apparently felt no pain. The boy stood on burning coals and stabbed his arms with knives to earn money. He died in a fall before the researchers could meet him. But the team was able to find members of the boy's extended family. They also seemed unable to feel pain. This may lead to bad results. These children sometimes burned themselves with hot liquids or steam. They sat on hot hearting devices. They cut their lips with their teeth,but felt no pain. Two of the children bit off one-third of their tongue. Yet they could feel pressure and tell differences between hot and cold. Why were they unable to feel pain? Doctor Woods and his research team studied DNA-deoxyribonucleic acid from the children. They also examined DNA from the children's parents. The team found that all had health. The researchers found that each child received a faulty version of the gene from a parent. The gene is called SCN9A. It gives orders to a protein that serves as a passageway for the chemical sodium(钠). All nerve cells have such passages. This is how spinal cord and brain work. Researchers discovered something important about SCN9A. They linked it to a rare condition in which patients suffer painful burning in their feet or hands. The problems of these patients were nearly opposite to those of the children who felt no pain. "In patients with the painful burning hands and feet, SCN9A was too active. The findings may mean better medical help for pain," Doctor Woods says. |
