Investigating the Co-administration of Ghrelin and Nicotine into the Medial Septum and Its Influencing on Morphine Amnestic Effect. مجله علوم اعصاب پایه و بالینی. 1402; 14 (3) :365-374
چکیده:
Introduction: Evidence indicates that medial septum nicotinic receptors regulate cognitive processes. Ghrelin is a gut hormone that regulates energy homeostasis. Ghrelin is also produced in the brain and is involved in cognitive function. This study aims to evaluate the effects of medial septal administration of ghrelin on the amnestic effect of morphine in rats.In addition, the possible relationship between the medial septal ghrelin and acetylcholine nicotinic receptors on the amnestic effect of morphine is evaluated.
Methods: The rats were implanted at the medial septum area and were microinjected with ghrelin and nicotinic receptor agents. The step-through type inhibitory avoidance apparatus was used for memory retrieval assessment.
Results: The results showed that the administration of morphine after the training phase impaired memory consolidation. Post-training intra-septal injection of the same doses of either ghrelin or nicotine did not change memory performance; however, their co-application with morphine (significant dose: 7.5 mg/kg subcutaneous injection) increased the step-through latency and improved memory consolidation. Moreover, post-training co-application of low doses of the two agonists could not affect morphine-induced memory impairment.
Conclusion: These results indicated no interaction between medial septal ghrelin and nicotinic receptors on the amnestic effect of morphine in rats.
