| ABSTRACT Methamphetamine (METH) is widely abused in worldwide. METH use could damage the dopaminergic system and induce cardiotoxicity via oxidative stress and mitochondrial dysfunction. Edaravone, a sedative-hypnotic agent, is known for it's antioxidant properties. In this study we used edaravone for attenuating of METH-induced cardiotoxicity in rats. The groups (six rats in each group) were as follows: control, METH (5 mg/kg IP) and edaravone (5, 10 and 20 mg/kg, IP) was administered 30 min before METH. After 24 hours, animals were killed, heart tissue was separated and mitochondrial fraction was isolated and oxidative stress markers were measured. Edaravone significantly (p<0.05) protected the heart against lipid peroxidation by inhibition of... |

| Sleep loss is both common and critically relevant to our society and might lead to the abuse of psychostimulants such as amphetamines, cocaine and modafinil. Since psychoactive substance abuse often occurs within a scenario of sleep deficit, the purpose of this investigation was to compare the sleep patterns of rats challenged with cocaine (7 mg/kg, ip), methamphetamine (7 mg/kg, ip), or modafinil (100 mg/kg, ip) subsequent to paradoxical sleep deprivation (PSD) for 96 h. Our results show that, immediately after 96 h of PSD, rats (10 per group) that were injected with a psychostimulant presented lower percentages of paradoxical sleep compared to those injected with saline (P < 0.01). Regarding slow wave sleep (SWS), rats injected with psychostimulants... |
