Abstract
Purpose: Regarding a wide variety of researches conducted with various therapeutic effect of crocin, the main constituent of saffron, the current study aims to assess the efficacy of crocin to improve learning and memory impairment caused by withdrawal following concurrent usage of ethanol (Eth) and nicotine (Nic) in adolescent male rats.
Methods: In order to test memory fucntion, Morris water maze and passive avoidance methods were applied in male Wistar rats undergone adolescent Nic-Eth withdrawal and the effect of crocin treatment was assessed at both behavioral and biochemical levels. The biochemical parameters included the inflammatory cytokines, indicators of oxidative stress and cholinergic metabolism within the hippocampla tissues. Animals were divided into 7 experimental groups as follows: 1) control (saline + saline), 2) nicotine + ethanol, 3-5) nicotine + ethanol + crocin (three doses), 6) nicotine + ethanol + bupropion + naloxone and 7) saline + crocin.
Results: Results indicated that crocin treatment effectively prevented the Nic-Eth withdrawal induced behavioral manifestations of memory impairment when assessed by Morris water maze and passive avoidance tests. In addition, the biochemical alterations (in inflammatory, oxidative and cholinergic parameters) induced by Nic-Eth withdrawal were also ameliorated in rats treated by crocin. Interestingly, the mentioned ameliorative effect of crocin was found to be dose-dependent in most experiments and almost equipotential to that of bupropion and naloxone co-administration, when administered at high doses.
Conclusion: We would like to suggest the crocin treatment as an alternative medication for the management of Nic - Eth withdrawal, however, further studies are required to assess the unknown side effects and high dose tolerability of the drug in human subjects.
期刊介绍：
Neuroscience Letters is devoted to the rapid publication of short, high-quality papers of interest to the broad community of neuroscientists. Only papers which will make a significant addition to the literature in the field will be published. Papers in all areas of neuroscience - molecular, cellular, developmental, systems, behavioral and cognitive, as well as computational - will be considered for publication. Submission of laboratory investigations that shed light on disease mechanisms is encouraged. Special Issues, edited by Guest Editors to cover new and rapidly-moving areas, will include invited mini-reviews. Occasional mini-reviews in especially timely areas will be considered for publication, without invitation, outside of Special Issues; these un-solicited mini-reviews can be submitted without invitation but must be of very high quality. Clinical studies will also be published if they provide new information about organization or actions of the nervous system, or provide new insights into the neurobiology of disease. NSL does not publish case reports.
