| Outline of Final Research Achievements |
Nine-week-old male SHR/NDmcr-cp rats and Sprague–Dawley (SD) rats were fed with high-fat and high-cholesterol (HFC) diets for 9 weeks. At 18 weeks of age, rats developed non-alcoholic steatohepatitis (NASH) with advanced hepatic fibrosis. In contrast, SD rats fed with high-fat without high-cholesterol diets did not develop NASH and fibrosis. This may indicate that dietary cholesterol induces hepatic features of NASH and eventually progressed cirrhosis in rats within 9 weeks. Phycocyanin is a pigment found in the blue-green algae, Spirulina, which possesses anti-oxidative and anti-inflammatory effects. SD rats fed an HFC diet with phycocyanin did not reveal an obvious histopathological improvement, whereas serum transaminases levels tended to decrease in a dose-dependent manner.
