Objective: It has been shown that berberine, a major component of Berberis vulgaris extract, modulates the activity of several neurotransmitter systems including dopamine (Da) and N-methyl-D-aspartate (NMDA) contributing to rewarding and reinforcing effects of morphine. Drug craving and relapsing even after a long time of abstinence therapy are the most important problems of addiction. In the p...
background: role of nitric oxide (no) in morphine-induced conditioned place preference (cpp) has already been proposed in the rat medial septum (ms), but no molecular evidence has been provided to clear this fact. methods: effects of intraseptal injections of l-arginine and/or ng-nitro-l-arginine methyl ester (l-name) on morphine place conditioning in wistar rats were examined. morphine (2.5-7....
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...
Introduction: Topiramate is a newly anti-convulsant drug, which acts as NMDA glutamate receptor antagonist as well as the GABAB receptor agonist. It is used for physical dependence to opioids as well as cocaine, nicotine, alcohol and ecstasy dependence. In the present study attempts were made to further identification of the effects of topiramate on the acquisition and expression of morphine...
In the present study, involvement of the N-methyl-d-aspartate (NMDA) receptors of the CA1 region of dorsal hippocampus (intra-CA1) in the acquisition or expression of morphine-induced conditioned place preference in rats was studied. Male Wistar rats were used in these experiments. NMDA-receptor agonist (NMDA) and antagonist (MK-801) were injected into the CA1 region of the dorsal hippocampus (...
The present study focused on the effects of 1-amino-3,5-dimethyladamantane (memantine), a clinically used, low-affinity N-methyl-D-aspartate channel blocker, on the motivational impact of morphine and morphine withdrawal syndrome. Memantine (7.5 mg/kg) inhibited the acquisition as well as the expression of morphine-induced conditioned place preference. However, memantine did not affect signific...
Recent evidence suggests that cannabinoid CB(1) receptors may represent effective targets for therapeutic agents used to treat cocaine and heroin relapse. However, the role of cannabinoid CB(1) receptors in the potential treatment for other drugs of abuse is still largely unknown. The present study was conducted to determine whether cannabinoid CB(1) receptors play a similar role in relapse to ...
