The attenuation of pain behaviour and serum interleukin-6 concentration by nimesulide in a rat model of neuropathic pain.

Background Evidence for a role of immune system in hyperalgesic pain states is increasing. Recent work in neuroimmunology suggests that the immune system does more than simply perform its well known functions of recognizing and removing invading pathogens and tumors. Interest in neuroinflammation and neuroimmune activation has grown rapidly in recent years with the recognition of the role of central nervous system inflammatiom and immune responses in the aetiology of pain states.

Carbamazepine effects on pain management and serum IL-6, IL-10 evaluation in addicted patients undergoing surgery.

Postoperative pain control remains an important issue in the field of surgery. Assessing and managing patients with acute pain who are addicted to opioids are often challenging. It has been shown that, addicted patients are less tolerant to pain.

Minocycline Effects on IL-6 Concentration in Macrophage and Microglial Cells in a Rat Model of Neuropathic Pain.

Background: Evidence indicates that neuropathic pain pathogenesis is not confined to changes in the activity of neuronal systems but involves interactions between neurons, inflammatory immune and immune-like glial cells. Substances released from immune cells during inflammation play an important role in development and maintenance of neuropathic pain. It has been found that minocycline suppresses the development of neuropathic pain.

The Attenuation of Pain Behavior and Serum COX-2 Concentration by Curcumin in a Rat Model of Neuropathic Pain.

Background: Neuropathic pain is generally defined as a chronic pain state resulting from peripheral and/or central nerve injury. There is a lack of effective treatment for neuropathic pain, which may possibly be related to poor understanding of pathological mechanisms at the molecular level. Curcumin, a therapeutic herbal extract, has shown to be effectively capable of reducing chronic pain induced by peripheral administration of inflammatory agents such as formalin.

Immunomodulatory activities of chitin microparticles on Leishmania major-infected murine macrophages.

Background: Chitin microparticles (CMPs) are found to be potent macrophage stimulators; however, their immunomodulatory effects on the parasite-infected macrophages have not yet been studied. To address this issue, we used a Leishmania major-infected murine macrophage model and characterized the regulatory effects of CMPs on the parasite-infected cells.

Methods: Mouse peritoneal macrophages were prepared and infected with L.

Suppression of interleukin-6 by minocycline in a rat model of neuropathic pain.

Inflammatory mediators produced in the injured nerve have been proposed as contributing factors in the development of neuropathic pain. In this regard an important role is assigned to interleukin-6. The present study, evaluated the effect of pretreatment with minocycline, on pain behavior (hyperalgesia and allodynia) and serum level of interleukin-6 in chronic constriction injury (CCI) model of neuropathic pain in rat.
