Effects of growth hormone on circulating neutrophil activation in septic peritonitis rats induced by lipopolysaccharide / 中华急诊医学杂志

ABSTRACT

Objective To study the effect of growth hormone (GH) on circulating neutrophil activation in septic peritonitis rats induced by lipopolysaceharide.Methods Male Wistar rats were divided into six groups (n=7) in randomized mannernormal control,septic peritonitis,septic peritonitis plus GH (0.5 mg/kg),septic peritonitis plus GH (1.0mg/kg),septic peritonitis plus GH (2.0 mg/kg),GH alone (2.0 mg/kg).Septic peritonitis rats were induced by lipopolysaccharide.CD11b expression and an oxidative burst of neutrophils were detected by flow cytornetric analysis. Results Growth hormone significantly increased sepsis-induced expression of CD11b and oxidative burst of circulating neutrophils (P＜0.01).Control animals treated with GH alone had CD11b expression and oxidative burst similar to that animals,treated with saline.Conclusion Treatment of GH may be harmful,instead of beneficial,on sepsis-induced organ injury.
