| Research Abstract |
This study examined the effect of repeated administration of methamphetamine (METH) on endoplasmic reticulum stress (ERS) in the dopaminergic neurons of rats. Lower doses of METH (0.5 and 1.0 mg/kg/day for 5d) increased GRP78 (KDEL), one of ERS markers, although superoxide dismutase-1, but no GRP78, was increased at higher doses (5 and 10 mg/kg/day for 5d). Further studies on ERS in METH-treated rats could contribute the understanding of the pathophysiology of METH-induced neuronal damages.
