This subproject is one of many research subprojects utilizing theresources provided by a Center grant funded by NIH/NCRR. The subproject andinvestigator (PI) may have received primary funding from another NIH source,and thus could be represented in other CRISP entries. The institution listed isfor the Center, which is not necessarily the institution for the investigator.Realistic models of battlefield injury must look at several simultaneous insults or a chain of sucessive degenerating physiological condidtions. Chlorine gas inhilation is a serious problem in warfare, with the problem more serious in light of recent terrorist activity.We propose to monitor the phyiological effects of chlorine gas inhilation over a 96 hour test to simulate battlefield conditions for military applications. The animal model was developed independently by the US Army, and is a combination gas toxcity/hemorrhage model in a pig. DOS will be used to measure tissue hypoxia and the onset of shock before, during, and after the insult to better undertand how tissues react to chemical warefare agents.
