Objective(s): Present study investigated the neuroprotective effects of selegiline and the molecular mechanisms involved in methamphetamine-induced neurotoxicity.Materials and Methods: Male wistar rats were randomly divided into six groups (10 rats in each group). Group 1 and group 2 received normal saline and methamphetamine (10 mg/kg),...

This study was conducted to evaluate the effect of soy milk on serum 17- β estradiol level and number of neurons in cerebral cortex and hippocampus as well as determination of the ratio of neurons in cortical and hippocampal regions in neonatal ovariectomized rats. Thirty female rats (one day old) were divided into six groups of five. At day 7, ovariectomy surgery was performed in four groups a...

The regional distribution of c-Jun expression and of the number of apoptotic cells was compared in various brain areas after methamphetamine administration to mice. Our results showed that there was methamphetamine-induced overexpression of c-Jun in the cortex and striatum but not in the cerebellar cortex. There was an almost totally similar regional appearance of methamphetamine-induced apopto...

Authors explored grey-matter density in 29 methamphetamine abusers and 20 healthy comparison subjects using voxel-based morphometry. Grey-matter density changes and performances on the Wisconsin Card Sorting test (WCST) were also compared between 11 short-term (<6 months) and 18 long-term (>or=6 months) abstinent methamphetamine abusers. Methamphetamine abusers had lower grey-matter density in ...

Background Isolation-reared mice show social encounter-induced hyperactivity with activation of prefrontal serotonergic and dopaminergic systems, but it is not known whether this stress response is observed in other pathological conditions. Here we examined whether the social encounter stimulation induces abnormal behavior during withdrawal in chronic methamphetamine-treated mice. Methods To ...

Methamphetamine abuse in young adults has long-term deleterious effects on brain function that are associated with damage to monoaminergic neurons. Administration of glial cell line-derived neurotrophic factor (GDNF) protects dopamine neurons from the toxic effects of methamphetamine in animal models. Therefore, we hypothesized that a partial GDNF gene deletion would increase the susceptibility...

BACKGROUND The medical literature reports health hazards for law enforcement personnel from repeated exposure to methamphetamine and related chemical compounds. Most effects appear transitory, but some Utah police officers with employment-related methamphetamine exposures developed chronic symptoms, some leading to disability. This report is of an uncontrolled retrospective medical chart evalua...

major hazardous environmental pollutants. MeHg is easily absorbed from the intestine, and transported into the brain across the blood-brain barrier. It has been demonstrated that MeHg neurotoxicity may be modulated by dysfunction of astrocytes such as disturbing ion homeostasis and the uptake of glutamate [a major excitatory transmitter of the central nervous system (CNS)] in cultures, since gl...

Effect of cadmium treatment on brain lipids, lipid peroxidation and distribution of Zn, Cu and Fe in rat brain regions was investigated. Adult male rats were exposed to Cd (100 ppm Cd as cadmium acetate) in drinking water for 30 days. The Cd exposure resulted in a significant decrease in the phospholipid content and an increase in the lipid peroxidation in the cerebral cortex and cerebellum. Th...
