Gut mucosal homeostasis and cellular mediators after severe thermal trauma and the effect of insulin-like growth factor-I in combination with insulin-like growth factor binding protein-3.

Increased small bowel epithelial cell apoptosis and decreased cell proliferation lead to impairment of gut mucosal integrity and function after thermal injury. Impairment of gut integrity is associated with increased bacterial translocation and incidence of sepsis. The purpose of this study was to determine whether IGF-I/IGF binding protein (IGFBP)-3 can improve small bowel homeostasis after injury and by which cellular mechanisms these changes occur and to identify changes in apoptosis-related genes after burn and the effect of bile acid on small bowel epithelial cell apoptosis after burn.

The effect of growth hormone on gut mucosal homeostasis and cellular mediators after severe trauma.

Background: Gut mucosal integrity and function is impaired after severe trauma with associated increases in small bowel epithelial cell apoptosis and decreases in cell proliferation. Growth hormone improves gastrointestinal function during chemotherapy and has anabolic effects on protein synthesis. The purpose of this study was to determine whether growth hormone can improve small bowel homeostasis after injury and by which cellular mechanisms these changes occur.
