ABSTRACT
<p><b>OBJECTIVE</b>To apply an orthogonal design optimization strategy to a mouse model of acute liver failure induced by D-galactosamine (D-GalN) and lipopolysaccharide (LPS) exposure.</p><p><b>METHODS</b>A four-level orthogonal array design (L16(45)) was constructed to test factors with potential impact on successful establishment of the model (D-GalN and LPS dosages, and dilution rate of the D-GalN/LPS mixture). The mortality rate of mice within 24 hours of D-GalN/LPS administration was determined by the Kaplan-Meier method. The model outcome was verified by changes in serum alanine transferase level, liver histology, and hepatocyte apoptosis.</p><p><b>RESULTS</b>The orthogonal array identified the optimal model technique as intraperitoneal injection of a combination of D-GalN and LPS at dosages of 350 mg/kg and 30 mug/kg, respectively, and using a dilution rate of 3. The dosages tested had no effect on survival. The typical signs of liver failure appeared at 6 hrs after administration of the D-GalN/LPS combination.</p><p><b>CONCLUSION</b>The orthogonal design optimization strategy provided a procedure for establishing a mouse model of acute liver failure induced by D-GalN and LPS that showed appropriate disease outcome and survival, and which will serve to improve future experimental research of acute liver failure.</p>
