Objective: Ferula assa-foetida, a native species in Iran, is used for treatment of several diseases particularly for neurological disorders in Iranian Traditional Medicine. The aim of this study is to investigate the effect of methanolic roots, fruits, and aerial parts extracts of Ferula assa-foetida on withdrawal syndrome in morphine-dependent mice. Materials and Methods: Aerial parts, roots, ...

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 ...

Introduction: Morphine withdrawal syndrome is mediated via several central and peripheral neurological pathways. In the present study we investigated the role of N-methyl-D aspartic acid (NMDA) glutamate receptor on naloxone-induced withdrawal syndrome in morphine-conditioned mice. Materials and Methods: We designed two separate experiments. In experiment one, 30 male NMRI mice were divide...

background thymus species are well known medicinal plants which the previous studies suggested the involvement of the opioid system in them. objectives this study aimed to investigate the effects of methanolic extract and essential oil of aerial parts of thymus daenensis (td), an endemic aromatic medicinal plant of iran, on morphine withdrawal syndrome in mice. materials and methods experiments...

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 ...

It has been suggested that an increase firing rate of noradrenergic neurons of the locus ceruleus is responsible for the opiate withdrawal syndrome. However, lesion studies have indicated that the noradrenergic neurons of the locus ceruleus are not essential for either the expression or suppression by clonidine of opiate withdrawal. The present study was designed to determine the effect of the ...

Hyperactivity of noradrenergic locus coeruleus (LC) neurons following withdrawal from chronic opiates has been implicated in the opiate withdrawal syndrome. Here, we report that local withdrawal induced in vivo by microinfusion of an opiate antagonist into the LC of morphine-dependent rats marginally, but significantly, activated LC neurons above the level obtained with local naloxone microinfu...

Previous pharmacological studies have implicated serotonergic brain systems in opiate withdrawal. To test the hypothesis that serotonin (5-HT) has a critical role in the development of opiate withdrawal, we have employed a near-total brain 5-HT system lesion technique (90% depletion) using 5,7-dihydroxytryptamine combined with induction of opiate dependence by implantation of morphine pellets o...

Introduction: Morphine addiction and morphine withdrawal syndrome are the two main problems of today’s human society. The present study has investigated the effects of nicotine on the strength of physical and psychological dependency in single and repeated doses morphine administrated rats. Methods: Male Wistar rats were subjected to morphine consumption with single or frequent dose protocols. ...
