The drug Neupogen is the first ever approved for the treatment of acute radiation injury and the approval came as a result of research performed by the University of Maryland School of Medicine (UM SOM) scientists claims a study. The investigators did their research in a non-human clinical model of high-dose radiation. 'Our research shows that this drug works to increase survival by protecting blood cells' said Thomas MacVittie one of the researchers. 'That is a significant advancement because the drug can now be used as a safe and effective treatment for the blood cell effects of severe radiation poisoning'
