anxiety assessment in methamphetamine - sensitized and withdrawn rats: immediate and delayed effects
objective: the anxiety profile in the stimulant-sensitized animals is not clear. thus, this study was conducted to elucidate the effects of acute and chronic administration of methamphetamine (meth) on the anxiety profile. the aim of this study was to examine whether meth-sensitized rats would show an increase in the expression of anxiogenic-like behaviors and to determine whether a low dose of...
objective: this study was designed to examine the effect of environmental enrichment during methamphetamine (meth) dependency and withdrawal on methamphetamine-induced spatial learning and memory deficits and obsessive-compulsive behavior. method: adult male wistar rats (200 ± 10 g) chronically received bi-daily doses of meth (2 mg/kg, sc, with 12 hours intervals) for 14 days. rats reared in st...
Both HIV infection and methamphetamine dependence can be associated with brain dysfunction. Little is known, however, about the cognitive effects of concurrent HIV infection and methamphetamine dependence. The present study included 200 participants in 4 groups: HIV infected/methamphetamine dependent (HIV+/METH+), HIV negative/methamphetamine dependent (HIV-/METH+), HIV infected/methamphetamine...
Combined use of an opioid with a psychostimulant is popular among drug abusers. Such “polydrug use” may increase drug effects or attenuate adverse effects of either drug alone. We proposed that a combination of methamphetamine (meth) and morphine may change physical opioid withdrawal symptoms. Adult male rats were chronically injected with cumulative subcutaneous (s.c.) doses of morphine, meth ...
objective(s): this study evaluated the effect of swimming exercise during spontaneous methamphetamine (meth) withdrawal on the anxiety, depression, obsessive-compulsive disorder (ocd) and voluntary meth consumption in meth-dependent rats. materials and methods: male wistar rats were repeatedly administered with bi-daily doses of meth (2 mg/kg, subcutaneous) over a period of 14 days. exercised ...

Abuse of methamphetamine (METH) is a frequent comorbidity among individuals infected with human immunodeficiency virus (HIV) type 1. In cell cultures and animal models, METH accelerates retroviral replication. To determine whether METH increases HIV replication in humans, we evaluated HIV loads in HIV-positive METH users and nonusers. We studied 3 groups: Tox+, active METH use and positive urin...
Abuse of the stimulant drug methamphetamine is associated with neural injury and neuropsychological (NP) deficits, while the residual effects of marijuana use remain uncertain. We sought to determine if methamphetamine dependent persons who also met criteria for marijuana abuse or dependence evidenced different NP performance than those with dependence for methamphetamine alone. We examined thr...
Genetic studies on METH abuse and METH psychosis are influential in the fields of comorbidity of substance abuse, etiological models of schizophrenia, and the nosology of prolonged or chronic substance-induced psychosis. Most data of genetic markers associated with METH abuse or METH psychosis derived from Asian samples. Previous studies on Meth abuse and Meth psychosis have identified many pot...
Several lines of evidence suggest that the dopaminergic nervous system contributes to methamphetamine (METH) dependence, and there is increasing evidence of antagonistic interactions between dopamine and adenosine receptors in METH abusers. We therefore hypothesized that variations in the A1 adenosine receptor (ADORA1) gene modify genetic susceptibility to METH dependence/psychosis. In this stu...
