| Outline of Final Research Achievements |
In order to determination of biomarkers and the mechanism of action in sudden death related administration of multiple psychotropic drugs, we investigated changes of metabolites in plasma of rats injected with single or various combinations of representative psychotropic drugs by GC-MS/MS based plasma metabolic profiling over time. In multiple drug combination models, 93 metabolites were detected. Each time group was separated from one another on the PCA and PLS score plots, especially in 12 hours, and characteristic metabolites changes correlated with the energy production (glycolysis, TCA cycle, and lipid metabolism, etc.) were detected.
