title: Effect of recombinant human granulocyte/macrophage colony-stimulating factor on the healing of colonic anastomosis in rats.
abstract: The purpose of this study was to investigate the efficacy of recombinant human granulocyte/macrophage colony-stimulating factor (rHuGM-CSF) on the wound healing of colonic anastomosis in rats. In total, 40 male Wistar rats were taken into this study. The control group (n = 20) received subcutaneous saline injection. The experiment group (n = 20) received rHuGM-CSF at 100 microg/kg subcutaneously. Both groups underwent colonic anastomosis 2 days later. In each group, burst pressure and hydroxyproline levels were determined 3 and 7 days after anastomosis. White blood cell (WBC) and red blood cell (RBC) counts were determined in each group to evaluate the effect of rHuGM-CSF on hematologic parameters in rats. There was no significant difference between the two groups in regard to burst pressure and hydroxyproline levels (p > .05). As expected, WBC counts significantly increased in the experiment group on days 3 (p = .035) and 7 (p = .046) following surgery. In conclusion, rHuGM-CSF administration and increased WBC counts did not have any positive effect on the wound healing of colonic anastomosis.
