We investigated the effects of (R)-(-)-5-methyl-1-nicotinoyl-2-pyrazoline (MS-153), which is reported to accelerate glutamate uptake, on the development of morphine tolerance and physical dependence in mice. For the induction of morphine tolerance and dependence, mice were twice daily treated with morphine (10-45 mg/kg, s.c.) for 5 days. First, co-administration of MS-153 (12.5 mg/kg, s.c.) did...
cAMP response-element binding protein (CREB), a transcription factor involved in learning, memory and drug addiction, is phosphorylated by calcium-calmodulin-dependent protein kinase IV (CaMKIV). Here, we show that CaMKIV-knockout (KO) mice developed less analgesic tolerance after chronic morphine administration with no alteration in physical dependence or acute morphine-induced analgesia. The ...
introduction: there are some evidences that the matricaria recutita extract has sedative effects and relieves symptoms of morphine withdrawal syndrome. symptoms of this syndrome are due to increased expression of fos transcription factor in brain. in this study the effect of chronic hydro alcoholic extract (30 mg/kg) of matricaria recutita on jumping behavior and expression of fos transcription...
The expression of mRNAs for the glial glutamate transporters, GLT-1 and GLAST, in the rat brain accompanied with morphine dependence and naloxone-precipitated withdrawal was investigated by Northern blot analysis. The expression of GLT-1 mRNA was significantly decreased in the striatum and thalamus of morphine-dependent rats, and significantly increased in the striatum 2 h after the naloxone-pr...
introduction: the aim of this study was to evaluate the changes in camp and some other cellular ingredients following adenyl cyclase activation in paragigantocellularis (pgi) neurons of morphine dependent and withdrawn rats. material and methods: the 3.5 mm thick brainstem slice prepared from pgi area (-10.04 to -13.24 from bregma) of control and morphine dependent rats (n=5 in each group). wer...
Previous studies from our laboratory and others have implicated a critical role of Ca(2+)/calmodulin-dependent protein kinase II (CaMKII) in opioid tolerance and dependence. Translational research targeting the CaMKII pathway is challenging, if not impossible, because of a lack of selective inhibitors. We discovered in a preliminary study that haloperidol, a butyrophenone antipsychotic drug, in...
Objective: Opioid dependence is a chronic and complex disorder characterized by relapse remission. Chronic administration of morphine causes symptoms physical psychological dependence. The purpose the present study was to investigate effect anti-addictive drugs such as bupropion varenicline on naloxone precipitated withdrawal syndrome in rat model. Materials Methods: To assess morphine, Wistar ...
OBJECTIVES This research aims at studying the neuroendocrine effects of music on creating morphine dependence in mice using conditioned place preference (CPP). METHODS The mice treated with 10 mg/kg morphine subcutaneously, fast music and slow music. Morphine was used to create dependence. In order to recognize the morphine rewarding effects, CPP technique was used. In the conditioning stage ...
Introduction: There are evidences showing the role of nitric oxide in the opiate reward properties. The role of nitric oxide signaling pathway as an intracellular mechanism on augmentation of long term potentiation in hippocampal CA1 area of rats is also confirmed. It has been also reported that oral morphine dependence facilitates formation of spatial learning and memory via activation of N...
Individual differences in behavioral characteristics or initial responses to abused drugs had been recently demonstrated to have predictive value in the propensity of later abuse. The research described here was initiated to determine the initial response of rats to administration of morphine if the physiological response has predictive value for the propensity of the animals to later selfadmin...
