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. ...

OBJECTIVE The goal was to determine whether withdrawal from sugar can cause signs of opioid dependence. Because palatable food stimulates neural systems that are implicated in drug addiction, it was hypothesized that intermittent, excessive sugar intake might create dependency, as indicated by withdrawal signs. RESEARCH METHODS AND PROCEDURES Male rats were food-deprived for 12 hours daily, i...

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...

A number of experimental studies have found that reactive oxygen species are involved during morphine treatment or withdrawal. The aims of this study were to analyse whether morphine administration and/or removal are related to peroxide generation and/or signs of withdrawal in rats, and whether the changes in antioxidant status induced by the administration of an antioxidant may modify peroxide...

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...

Introduction: The aim of this study was to assess the effect of Ca2+/calmodulin-dependent kinase IIα (CaMKIIα) inhibitor (KN-93) injection into the locus coeruleus (LC) on the modulation of withdrawal signs. We also sought to study the effect of chronic morphine administration on CaMKIIα activity in the rat LC. Methods: The research was based on behavioral and molecular studies. In the behav...

Previous studies suggest that binge eating sugar leads to behavioral and neurochemical changes similar to those seen with drug addiction, including signs of opiate-like withdrawal. Studies are emerging that show multiple neurochemical and behavioral indices of addiction when animals overeat a fat-rich diet. The goal of the present study was to utilize liquid and solid diets high in sugar and fa...
