| Research Abstract |
In this study, the pathological changes of cardiac region, especially impulse conducting system in amphetamines(MA)-abusers was investigated. In long term MA-treated mouse-model, cardiac tissue was examined by 2-dementional electrophoresis to observe the changes of protein expressions. After long-term 0MA treatment, mTOR passway, related to program cell death(PCD) was activated. Gene expressions of potassium-channel associated genes were down regulated in MA-treated mouse. MA might change the action potential of cardiac cells to induce the cardiac sudden death.
