AIMS The effects of intracerebroventricular administration of neuropeptide Y (NPY) on ethanol withdrawal were studied in rats. METHODS Ethanol was administered intragastrically five times daily for 4 days. At 16-17 h after the last infusion of ethanol, rats were rated for withdrawal using a score based on three signs: irritability, tremor and rigidity. Subsequently, the rats received an injec...

This research was done to test the effect of Rosa damascena essential oil on withdrawal signsof naloxone-precipitated morphine in male mice. Morphine dependence was induced by injection(IP) three times daily at doses of 50, 50 and 75 mg/kg, respectively, for 3 days. On day 4,after the last administration of morphine, Rosa damascena essential oil was administered atdifferent concentrations (5, 2...

The mechanisms of drug dependence and rewarding properties of opiates are not exactly known and several neurotransmitters seem to be involved. It is possible that the rennin-angiotensin system could interact with the opioid system, since it has been shown that angiotensin II(Ang) and ACE inhibitors have analgesic, anticonvulsant and antidepression effects and in some cases they could antagonize...

BACKGROUND AND PURPOSE Abrupt discontinuation of nicotine, the main psychoactive component in tobacco, induces a withdrawal syndrome in nicotine-dependent animals, consisting of somatic and affective signs, avoidance of which contributes to drug maintenance. While blockade of fatty acid amide hydrolase, the primary catabolic enzyme of the endocannabinoid arachidonoylethanolamine (anandamide), e...

In chronic smokers, nicotine withdrawal symptoms during tobacco cessation can lead to smoking relapse. rodent models, exposure elicited physical dependence, whereas acute antagonism of nicotinic acetylcholine receptors (nAChRs) immediately precipitated symptoms. Although the central serotonergic system plays an important role in withdrawal, exact raphe nuclei regulating these remain unknown. We...

Introduction: It has been shown that orexin peptides have a role in opioid withdrawal behaviors. Orexin-expressing neurons that are present in the hypothalamic nuclei send dense projections to the Locus Coeruleus (LC). Withdrawal syndrome is temporally associated with hyperactivity of LC neurons. However, LC neurons do not show withdrawalinduced hyperactivity in the brain slices from morphine-d...

Drug addiction is a destructive misfortune that leads to recession in all social fields. For this reason, proper treatment of addiction should be seriously considered. Formerly, the effectiveness of TENS and ICWS methods on the reduction of withdrawal syndrome signs in the rat was evaluated separately. In this study the interaction of these two methods were analyzed. For this purpose, four grou...

Alcohol withdrawal hypertension is a common clinical problem which often goes unrecognized. We report a case in which the symptoms and signs of withdrawal with a marked elevation in blood pressure mimicked the features of a phaeochromocytoma. Despite a positive phentolamine test no further evidence for phaeochromocytoma was found and both blood pressure and symptoms settled as the features of a...
