Objective:
To evaluate the protective effect of recombinant human granulocyte colony stimulating factor (rhG-CSF) on acute hepatic failure induced by galactosamine (D-GalN) and lipopolysaccharide (LPS) in mice, and to explore its mechanism.
Methods:
The mice were intraperitoneally administered D-GalN (800 mg/kg) and LPS (10 microg/kg), and then were intraperitoneally injected either saline (the control group )or rhG-CSF at 300 microg/kg body weight (the therapy group) at 4 h, 2 h and 0 h before the D-GalN/LPS injection. The survival rate of the mice was estimated at 24 h after the D-GalN/LPS injection. The degree of hepatic injury was evaluated at 6 h after the D-GalN/LPS injection, and the levels of TNF-alpha, IFN-gamma, IL-6 and IL-10 mRNA were simultaneously measured by semiquantitative RT-PCR.
Results:
The survival rate of the therapy group was significantly higher than that of the control group (68.4% vs 20%, P<0.01). As compared with the control group, the degree of liver injury in the therapy group significantly decreased (P<0.05), and the levels of TNF-alpha and IFN-gamma mRNA in the hepatic tissue also reduced remarkably (P<0.01, respectively), while the levels of IL-6 and IL-10 mRNA increased (P<0.01, respectively) at 6 h after the D-GalN/LPS injection.
Conclusion:
G-CSF can protect the mice from acute hepatic failure induced by D-GalN/LPS.
