| Outline of Final Research Achievements |
Hepatocyte-derived serum enzyme activities were decreased in some hepatic disorders. In the Trichinella spiralis-infected rats, PON1 activity was decreased in the course of infection and other enzyme activity was also decreased. On the other hand, serum inflammatory cytokines were significantly increased throughout the course of infection. IL-4 and IL-10 as anti-inflammatory cytokines were also increased. In the liver tissue, infiltrations with inflammatory cells (lymphocytes, neutrophils and eosinophils) and degeneration of hepatocytes were observed. Expressions of mRNA of various enzymes derived from hepatocytes were also significantly depressed. T. spiralis infection in rats induced inflammatory response in the liver and then decreased serum enzyme activities which are derived from hepatocytes.
On the contrary, same parasite infection in mice induced anti-inflammatory response in the early phase of infection and resulted rather mild injuries in the liver tissues of mice.
