| Outline of Final Research Achievements |
We have investigated the mechanism of the onset of NASH and the preventive effects of voluntary exercise against NASH by using the animal model of STAM. We have proposed oxidative stress markers of lipids, hydroxylinoleic acids (HODE) which can provide the oxidative stress mechanism in vivo. It was found that plasma levels of HODE increased by the procession of the diseases compared to the control mice. It was interesting that the triglyceride levels in plasma and liver decreased significantly by exercise while the HODE levels were not changed significantly by the exercise. In conclusion, oxidative stress was indeed involved in the onset mechanism of NASH and exercise is prominent for the alleviation of the disease.
