orexin, mainly produced by orexin-expressing neurons in the lateral hypothalamus (lh), plays an important role in pain modulation. moreover, it is shown that the nucleus accumbens (nac) is one of the important areas involved in this modulation. orexin-1 (ox1) and orexin-2 (ox2) receptors are densely distributed in the nac. the study investigated the involvement of ox1 receptors in the nac on an...

Apple Cider Vinegar (ACV) is a natural compound that is used mainly in numerous food preparations. During the last few decades, ACV has been used for various therapeutic purposes in different countries. One of its main applications by people in Iran and other countries has been as an oral traditional remedy to control chronic pain in arthritis. In this study, ACV’s effects on acute and chronic ...

Upregulation of Ca(2+)-permeable AMPA receptors (CP-AMPARs) in the dorsal horn (DH) neurons of the spinal cord has been causally linked to the maintenance of persistent inflammatory pain. Therefore, inhibition of CP-AMPARs could potentially alleviate an, otherwise, poorly treatable chronic pain. However, a loss of CP-AMPARs could produce considerable side effects because of the crucial role of ...

  Pharmacologists believe analgesic and anti-inflammatory drugs such as non-steroidal anti-inflammatory drugs (NSAIDs) and opioid compounds, due to their side-effects and, in some cases, inadequacy, are not always useful. Therefore it seems necessary to search for newer analgesic compounds. In traditional Iranian Medicine, the leaf and rhizome of Sambucus ebulus is used as a topical medication ...

Endoplasmic reticulum (ER) stress is involved in many neurological diseases and inflammatory responses. Inflammatory mediators induce neuronal damage and trigger the neuropathic or inflammatory pain. But there is very little data on the role of the ER stress response in pain mechanisms. In this study, we explored whether the ER stress response is involved in orofacial inflammatory pain by using...

  Objective(s): The present study investigated the effects of microinjection of histamine and histamine H1, H2, and H3 receptor antagonists, chlorpheniramine, ranitidine and thioperamide, respectively into the primary somatosensory cortex (PSC) on inflammatory pain.   Material and Methods: Two stainless steel guide canulas were bilaterally implanted into the PSC of anaesthetized rats. Inf...

Abstract Background: For long time medical scientists have speculated about alleviation of pain so that they have attempted to prescribe a potent analgesic with the least side effects. There are some records in Iranian traditional medicine showing that Elaeagnus angustifolia L. decreases inflammation and pain. Therefore, in this study the analgesic effect of the aqueous extracts of E. angustif...
