Abstract

When BALB/cAJc1 mice are intravenously injected with heat-killed Propionibacterium acnes (P. acnes) followed by an intravenous injection of lipopolysaccharide (LPS) 7 days later, massive necrosis is induced in the liver tissue and most of the mice die within 24 hours of LPS injection. Using this experimental model, acute hepatic failure was induced in various strains of mice and the difference in the response was studied. As a result, as in BALB/cAJc1 mice, acute hepatic failure was also induced in BALB/cAJc1-nu, AKR/J, C3H/HeNJc1, C57BL/6NJc1 and DDy mice. However, as an exception, hepatic cell necrosis was hardly seen and the survival rate was remarkable high in C3H/HeJ mice, which genetically do not respond to LPS stimulation. These results indicate that for this experimental induction of acute hepatic failure, macrophages must be activated by the two-step stimulation of P. acnes and LPS.
