Abstract: 

Introduction: The limbic system plays an important role in neural mechanisms related to emotion and memory. Hallucinogenic drugs are a factor affecting the functioning of this system and interfering with its nervous system regulation. Recent studies on adolescent users of hallucinogenic drugs, such as marijuana, have shown some degree of behavioral and emotional disorders. Cannabinoids, compounds forming marijuana, acting via its receptors throughout the brain.Conclusion: These ligands bind to their receptors in parts of the limbic system (the amygdala, prefrontal cortex, hippocampus, thalamus and hypothalamus) and lead to changes in the expression of neurotransmitters and neural pathways in the brain. These alterations influence emotional behavior.

Abstract: 

Background and objective: Cannabinoids which are active compounds of marijuana show some pharmacological effects similar to the opioids. There are also functional interactions between both Cannabinoid and opioid systems. In this study we investigated the role of Cannabinoid receptors in central amygdala and its interaction with opioid system.Methods: In the present study, we investigated the effects of intraperitoneal injection of opioid drugs on response-induced by intra-amygdala (intra-Amyg) microinjection of Cannabinoid agents in rats, using elevated plus-maze test of anxiety.Results: Intraperitoneal injection of morphine (3, 6 and 9 mg/kg) increased %OAT and %OAE, but not locomotor activity, showing an anxiolytic response. However, some doses of the opioid receptor antagonist, naloxone reduced %OAT and locomotor activity as well. Intra-Amyg administration of CB1 Cannabinoid receptor agonist, ACPA (at the dose of 1.25 and 5 ng/rat) increased %OAT and %OAE but not locomotor activity, thus showing an anxiolytic response, which was increased by morphine (6 mg/kg, i.p.) without any interaction. Naloxone also reduced ACPA effects.Intra-Amyg administration of CB1 Cannabinoid receptor antagonist, AM251 (2.5, 25 and 100ng/rat) did not alter %OAT and %OAE but higher doses of drug (25 and 100 ng/rat) reduced locomotor activity. However, the drug in combination of morphine anxiolytic response and with naloxone decreased anxiety. Conclusion: The results may indicate an anxiolytic for CB1 Cannabinoid. Our results also showed that opioid system may have interaction with Cannabinoid receptor in the amygdale.

Abstract: 

NEUROINFLAMMATION, EXCITOTOXICITY AND OXIDATIVE STRESS ARE THE KEY MEDIATORS OF NEURODEGENERATION. ON THE OTHER HAND, THE END OCannabinoid (ECB) system IS CONSIDERED AS A REGULATOR OF MANY NEURONAL MECHANISMS THAT ARE RELEVANT TO NEURODEGENERATIVE DISORDERS. THE EXPRESSION LEVEL OF Cannabinoid RECEPTORS IN NEURONS AND GLIAL CELLS MAY CHANGE IN A NEUROLOGICAL DISEASE AND CHRONIC ALTERATIONS IN ECB SIGNALLING ARE OFTEN ACCOMPANIED WITH CHRONIC ACTIVATION OF THE IMMUNE system AND A NUMBER OF IMMUNE CELLS. ACTIVATION OF CB1 AND CB2 RECEPTORS ARE KNOWN TO BE INVOLVED IN THE REGULATION OF CALCIUM HOMEOSTASIS, MITOCHONDRIAL FUNCTION, AND NEUROTROPHIC PROCESS, WHILE OTHER RECEPTORS GATED BY CannabinoidS SUCH AS PPARG, ARE GAINING INTEREST IN THEIR ANTI-INFLAMMATORY PROPERTIES. BASED ON THESE MECHANISMS, DURING THE LAST TWO DECADES, PHARMACOLOGICAL MANIPULATION OF THE ENDOGENOUS Cannabinoid system, AS WELL AS APPLICATION OF PHYTOCannabinoidS AND SYNTHETIC CannabinoidS HAVE BEEN INVESTIGATED TO FIND NEW THERAPIES FOR NEURODEGENERATIVE CONDITIONS AND TARGETING THE Cannabinoid system HAS EMERGED AS A POTENTIAL THERAPEUTIC APPROACH TO TREAT MANY NEURODEGENERATIVE DISEASES SUCH AS MULTIPLE SCLEROSIS (MS), PARKINSON’S DISEASE (PD), AND ALZHEIMER’S DISEASE (AD). MOST OF THE SUPPORTING EVIDENCE HAS BEEN OBTAINED BY USING CELLULAR AND ANIMAL MODELS. META-ANALYSIS OF CLINICAL TRIAL REPORTS REVEALED THAT MOST BENEFICIAL EFFECTS OF CannabinoidS HAVE BEEN SHOWN IN THE TREATMENT OF MS. IN FACT, THERE IS MODERATE-QUALITY EVIDENCE FOR BENEFICIAL EFFECTS OF CannabinoidS IN RELIEVING SPASTICITY, NEUROPATHIC PAIN OR PAINFUL SPASMS, AND URINARY DYSFUNCTION IN MS PATIENTS. ORAL ADMINISTRATION OF Cannabinoid COMPOUNDS IS PROBABLY INEFFECTIVE FOR TREATING LEVODOPA INDUCED DYSKINESIA IN PATIENTS WITH PD. MOREOVER, ORAL CannabinoidS ARE OF UNKNOWN EFFICACY IN NON–CHOREA-RELATED SYMPTOMS OF HUNTINGTON DISEASE, TOURETTE SYNDROME, CERVICAL DYSTONIA, AND EPILEPSY. IT SHOULD BE NOTED THAT THE RISKS AND BENEFITS OF MEDICAL CannabinoidS SHOULD BE WEIGHED CAREFULLY. RISK OF SERIOUS ADVERSE PSYCHOPATHOLOGIC EFFECTS WAS NEARLY 1% AND CONSISTED OF ADDICTION, WITHDRAWAL SYNDROME, IMPAIRED MOTOR COORDINATION, SCHIZOPHRENIA, MOOD DISORDERS, AND PROGRESSION TO USE OF OTHER DRUGS. DESPITE THE FACTS MENTIONED ABOVE, THERE IS STILL TREND USING Cannabinoid COMPOUNDS WITH NO PSYCHOACTIVE ADVERSE EFFECTS SUCH AS CANNABIDIOL OR USING SELECTIVE ACTIVATOR OF CB2 RECEPTORS. AUGMENTATION OF ECB system IN THE CNS BY INHIBITING RELEVANT ENZYMES OR TRANSPORTERS IS ANOTHER THERAPEUTIC STRATEGY THAT WOULD BE EFFECTIVE IN THE TREATMENT OF NEURODEGENERATIVE DISEASES WITH LESS ADVERSE EFFECTS.

Abstract: 

Objective: In recent years Cannabinoids and their use have attracted a great deal of attention. The aim of the present examination is to study the effect of the Cannabinoid system and its interaction with the opioid system in state-dependent memory. Method: In this experimental study, the intracerebroventricular (ICV) administration of different doses of Cannabinoid agonists and antagonists, and the subcutaneous administration of morphine was used in the passive avoidance task. Results: Cannabinoid agonists prevent the retrieval of memory by morphine. Conclusion: The improvement of retrieval memory by morphine treatment seems to be induced, at least in part, through the Cannabinoid receptors.
