Ventrolateral periaqueductal gray exogenous and endogenous histamine attenuates sciatic nerve chronic constriction injury-induced neuropathic pain through opioid receptors

Sara Salimi; Esmaeal Tamaddonfard; Farhad Soltanalinejad-Taghiabad

Volume 12, Issue 4 , December 2021, , Pages 429-436

  The aim of the present study was to investigate the effects of intra-ventrolateral periaqueductal gray (vlPAG) microinjection of histamine and thioperamide (a histamine H3 receptor antagonist/inverse agonist) on neuropathic pain. To explore the possible mechanism, naloxone was microinjected alone or ...  Read More

Role of opioid system in verapamil-induced antinociception in a rat model of orofacial pain

Esmaeal Tamaddonfard; Amir Erfanparast; Mina Taati; Milad Dabbaghi

Volume 5, Issue 1 , March 2014, , Pages 49-54

  Calcium, through its various channels involves in local, spinal and supra-spinal transmission of pain. In the present study, we investigated the separate and combined treatment effects of verapamil (a calcium channel blocker), morphine (an opioid agonist) and naloxone (an opioid antagonist) on pain in ...  Read More

Effect of pilocarpine on the formalin-induced orofacial pain in rat

Esmaeal Tamaddonfard; Amir Erfanparast; Emad Khalilzadeh

Volume 3, Issue 2 , June 2012, , Pages 91-95

  In this study, the effects of subcutaneous (SC) injection of pilocarpine (a cholinomimetic agent) and atropine (a muscarinic receptors antagonist) were investigated on a tonic model of orofacial pain in rats. The contribution of the endogenous analgesic opioid system was assessed using naloxone (an opioid ...  Read More

Thioperamide-induced Antinociception is Mediated through Endogenous Opioid System in the Dentate Gyrus of Adult Rats

Emad Khalilzadeh; Esmaeal Tamaddonfard; Amir-Abbas Farshid; Amir Erfanparast

Volume 1, Issue 3 , December 2010, , Pages 166-173

  The present study investigated the effects of intra-dentate gyrus microinjection of naloxone (an opioid antagonist) and thioperamide (an antagonist of histamine H3 receptors) in the formalin test in rats. Subcutaneous injection of formalin (50 μl, 2.5 %) in the ventral surface of right hind paw produced ...  Read More

Antinociceptive Effect of Morphine Microinjections into the Dorsal Hippocampus in the Formalin-Induced Orofacial Pain in Rats

Amir Erfanparast; Esmaeal Tamaddonfard; Amir Abbas Farshid; Emad Khalilzadeh

Volume 1, Issue 2 , September 2010, , Pages 83-89

  In the present study, the effects of intra-hippocampal microinjections of morphine (an opioid agonist) and naloxone (an opioid antagonist) were investigated in the formalin-induced orofacial pain in rats. Orofacial pain was induced by subcutaneous injection of formalin (1 %, 50 μl) in the upper lip ...  Read More
