title: Recombinant human growth hormone modulates the hepatic acute-phase response and P-selectin in burned rats.
abstract: The purpose of this study was to determine the effect of recombinant human growth hormone (rhGH) on serum constitutive proteins, cytokines, P-selectin, and insulin-like growth factor (IGF-1) in the thermally injured rats.Sprague-Dawley rats (64 males) were given 30% total body surface area full thickness scald burn. They were randomly divided to receive either 2.5mg/kg per day im rhGH or saline (control). Rats were sacrified on postburn days 1, 2, 5, and 7, and serum constitutive proteins, cytokines, P-selectin, and IGF-1 levels were measured.Serum IGF-1 levels were increased on days 2, 5, or 7 after burn in rhGH-treated rats compared with controls (P<0.001, <0.01 and <0.001, respectively). Serum transferrin and albumin levels were increased on days 7 after burn in rhGH-treated rats compared with controls (P<0.05). The cytokines increased after thermal injury. The rhGH decreased serum levels of tumor necrosis factor-alpha on postburn days 1 compared with controls (P<0.001). Serum levels of interleukin-1 were decreased on days 1 and 2 after burn in rhGH treated rats compared with controls (P<0.001, <0.01, respectively). Rats receiving rhGH showed significantly increased P-selectin levels at 5 and 7 postburn days compared with controls (P<0.001). Our data indicate that rhGH, given after thermal injury, increased albumin, transferrin, IGF-1, and P-selectin levels and decreased serum tumor necrosis factor-alpha and interleukin-1 levels.
