background it has been elucidated that berberis vulgaris (barberry) can alleviate morphine withdrawal syndrome. also it has been reported that aqueous extract of barberry possibly have inhibitory effect on nmda receptors. objectives in this study, we decided to evaluate the effects of aqueous extract of b. vulgaris fruit on morphine tendency in mice using conditioned place preference (cpp) meth...

the effect of aqueous extract of nepata glomerulosa boiss. aerial parts on morphine withdrawal syndrome was investigated in mice. dependence was induced by subcutaneous injections of morphine for 3 consecutive days. on day 4, morphine was injected 2 h prior to intraperitoneal injection of naloxone. the number of jumps during a 20 min. period after naloxone injection was considered as a measure ...

In this study, the effect of reversible inactivation of locus ceruleus (LC) on naloxone- induced withdrawal syndrome in paragigantocellular (PGi) neurons in morphine- dependent rats was investigated. For inactivation of LC, 1 µl of lidocaine (2%) was used and for induction of withdrawal syndrome, naloxone hydrochloride (2 mg/kg) was injected systemically. The results showed that in dependent gr...

Previous pharmacological studies have implicated serotonergic brain systems in opiate withdrawal syndrome. Increased brain 5-HT release is associated with the development of physical dependence to morphine. Specific serotonin reuptake inhibitors, such as fluvoxamine and sertraline reduce the severity of naloxone precipitated opioid withdrawal syndrome. Other studies have shown that 5-HT system ...

Objective(s) Opioid abuse is still remained a major mental health problem, a criminal legal issue and may cause ischemic brain changes including stroke and brain edema. In the present study, we investigated whether spontaneously withdrawal syndrome might affect stroke outcomes. Materials and Methods Addiction was induced by progressive incremental doses of morphine over 7 days. Behavioral si...

Introduction: Methadone has been used as a drug to detoxify opioid tolerance. Naloxane precipitated morphine withdrawal behaviours were attenuated by venlafaxine as an antidepressant. On the contrary, after detoxifying the opioids, spontaneous withdrawal syndrome may occur with pain sensitivity. Therefore the present study aimed to examine the effects of chronic methadone (70 mg/kg, in dr...
