| Outline of Final Research Achievements |
To investigate Alzheimer's disease from the aspect of glucose metabolism in the brain, 13C NMR metabolite mapping in APP/PS1 mouse brain was observed after the infusion of 13C glucose. For highly sensitive data acquisition, 1H-detected 13C NMR spectroscopic imaging was utilized with a 7T MR system, 100G/cm gradient system and Tx/Rx separated RF coil system. 13C Glu/Gln signals of the brain increased to the maximal level at 2 hours after 13C glucose infusion, and then the signals gradually decreased in either APP/PS1 mice or wild type mice at the age of 18 months. Apparent differences in the signals between the two groups wwere not recognized, since natural abundant big 13C signals from fat tissue around the skull disturbed the observation of signals from the brain and variations among the experiments were big. Specific 13C signals of the brain in APP/PS1 mice were not detected.
