项目摘要
Acute lung injury can result from irritant chemical exposure released from terrorists' attacks including the
intentional detonation of chemical plants, railroad car derailments, or chemical truck hijacking. Often fatal, an
initial diagnosis of acute lung injury can be difficult because the onset of signs and symptoms can be delayed
hours or days after exposure. Histologically, acute lung injury is marked by epithelial and endothelial injury that
leads to delayed pulmonary edema with surfactant disruption, alveolar collapse, respiratory failure, and
ultimately, death. Based on its toxicity and industrial usage, acrolein is one of the chemicals of high concern to
the counterACT program. Lethal acrolein exposures have resulted following accidental release during
transportation and use. Terrorists’ attacks often produce massive fires that also can result in acrolein exposure,
as well as, carbon monoxide (CO) exposure. Current acute lung injury treatment is limited to supportive
strategies (managed ventilation and supplied oxygen). Importantly, many people are likely to be exposed to
concentrations that are not immediately lethal. In these individuals, pulmonary edema can be delayed for many
hours and occur with no initial symptoms. Thus, the majority of victims will be difficult to diagnose and health
care systems may be overwhelmed because patients cannot be triaged adequately. Treating individuals after
exposure but before symptoms develop provides a window of opportunity to prevent or diminish delayed
pulmonary edema. This proposal seeks to develop therapeutic countermeasures that are effective and safe for
use in the prevention and treatment of delayed pulmonary edema induced by acrolein, CO, and acrolein plus
CO and thereby reduce mortality.
