Peripheral Thermal Injury On Cerebral Integrity
Thermal injury is characterized by increased microvascular permeability, which causes massive fluid volume requirements during resuscitation. Peripheral tissue thermal injury often causes systemic reactions, such as fever, hyperalgesia, anorexia, and increased permeability of the blood-brain-barrier (BBB). Since thermal injury remains one of the leading causes of childhood death in the United States (one million children are injured and 3,000 children die each year as a result of burn trauma, according to the Children’s burn Awareness Program, Chicago), and since generalized encephalopathy is the most common neurologic complication of thermal injury in children occurring with a 14% incidence, research on the effect of peripheral thermal injury on cerebrovascular integrity is essential.
The two specific aims of our current studies are 1) to evaluate injurious effect of peripheral thermal injury on BBB integrity; 2) to investigate inflammatory mechanisms underlying BBB dysfunction. These studies could provide important new information on the mechanistic tissues in thermal injury on the central nervous system in the rat model. The results may lead to development of effective therapies on thermal injury beyond the level that current treatments achieve.
