Abstract:
AIM:Stress response induced by severe trauma can activate free radical, endothelial cell, and mononuclear macrophage to regulate the production and release of mediators of inflammation. In this study, we investigated the influence of semi-hepatectomy on cytokine in serum. METHODS:The experiment was performed at Clinical Laboratory of Datong Seventh People's Hospital from April to July 2006. The experimental procedure was accorded with animal ethical standards. Twenty-five healthy rabbits were selected and randomly divided into two groups. In hepatectomy group (n=20), semi-hepatectomy was performed by regular approach, following by abdominal closure when there was no active bleeding. In control group (n=5), only abdominal opening and closure was conducted. Peripheral venous blood was harvested 1 day before and 24 hours, 1, 2, 3, and 4 days after surgery (IGF) to examine the levels of cytokine in serum such as interleukin-2 (IL-2), IL-6, IL-8, tumor necrosis factor (TNF) and insulin-like growth factor by radioimmunity. RESULTS:Twenty-five rabbits were all included in final analysis. Compared with the control group, IL-2 increased 24 hours after surgery, and reduced even lower than preoperative level 1 week after surgery, but then increased gradually and approached to preoperative level 4 weeks after surgery. IL-6 and IL-8 were elevated within 24 hours after surgery, and reached the peak at 3 weeks, then began to reduce until the normal level 4 weeks after surgery. TNF decreased 24 hours after surgery, and then increased but decreased again 4 weeks after surgery. IGF increased 24 hours after surgery, reached the peak 2 weeks after surgery, and reduced to normal level 4 weeks after surgery. CONCLUSION:Hepatectomy can induce decrease in IL-2, T cell growth factor in peripheral blood, in rabbits.
