Research Abstract |
This study suggests that, in consideration of the neurotoxic effects of methamphetamine(METH) due to oxidative stress, pharmacological intervention on NO synthase may help reduce the monoamine-depleting and apoptosis-inducing effects of methamphetamine and that pretreatment with low-dose METH may be protective against METH neurotoxicity in the midbrain, leading to the suppression of oxidative stress and apoptotic mechanisms, in part via ER stress-related pathways. In the point of view of forensic pathology, an animal model of escalation drug intake and pretraetment of low-dose METH prior to neurotoxic-dose admistration could be useful to investigate the mechanisms involved in neurotoxicity of human METH abusers.
