Background and objectives: Pain is an unpleasant feeling which affects the quality of life and relieving from pain is an important goal in many treatment protocols. Apium graveolens L. (celery) has been considered as sedative, analgesic, carminative, antispasmodic and diuretic in Iranian traditional medicine. The aim of present study was to evaluate the anti-n...

objective(s):neuropathic pain is caused by lesions or diseases affecting the somatosensory system and often responds poorly to typical medications.  in this study, we evaluated anti-nociceptive effects of morphine, gabapentin and their combination on heat hyperalgesia, cold and mechanical allodynia in chronic constriction injury (cci) model of neuropathic pain in rats. materials and methods: mo...

The transient receptor potential ankyrin 1 (TRPA1) cation channel is one of the well-known targets for pain therapy. Herbal medicine is a rich source for new drugs and potentially useful therapeutic agents. To discover novel natural TRPA1 agonists, compounds isolated from Chinese herbs were screened using a cell-based calcium mobilization assay. Out of the 158 natural compounds derived from tra...

PURPOSE The present study was designed to investigate the anti-nociceptive activity of ethanolic leaf extract of Trema cannabina Lour (family: Cannabaceae) in experimental animal models. METHODS The anti-nociceptive action was carried out against two types of noxious stimuli, thermal (hot plate and tail immersion tests) and chemical (acetic acid-induced writhing) in mice. RESULTS Phytochemi...

abstract  introduction: hyperalgesia is considered as one the marked signs of subchronic diabetes mellitus that could affect the life style of the patients. with c onsidering the potential anti-diabetic effect of the medicinal plant withania somnifera (ws)( ashwagandha), this study was designed to investigate the analgesic effect of ws on formalin-induced nociceptive responses (standard formali...

The present study was performed to investigate the role of calcitonin gene-related peptide (CGRP) and its antagonist CGRP8-37 on nociception in the nucleus accumbens of rats. Hindpaw withdrawal latencies (HWLs) to noxious stimulation induced by hot plate and Randall Selitto tests were measured. The HWL to both thermal and mechanical stimulation increased significantly after intra-nucleus accumb...

Objective: Migraine is the most common primary headache disorder in children. However, its pathogenetic mechanisms are not fully understood. Researchers focused on Orexin A (a neuropeptide with anti-nociceptive effects) and B pro-nociceptive effects), but literature scarce terms of studies investigating plasma levels these neuropeptides pediatric migraine patients. We aimed to compare orexins b...

This study was designed to investigate the anti-inflammatory and anti-nociceptive activity of the methanol extract from the aerial part of Phlomis younghusbandii (MEAP) and to explore the possible related mechanisms. Anti-inflammatory effects of MEAP were evaluated by using the ear edema test induced by dimethylbenzene and vascular permeability test induced by acetic acid. Anti-nociceptive acti...

INTRODUCTION Nociception is the process by which intense thermal, mechanical or chemical stimuli are detected by a subpopulation of peripheral nerve fibers, called nociceptors (Basbaum and Jessell, 2000) and nociceptive refers to the potential of a stimulus to produce a tissue lesion and a reaction from the organism. Nociceptive pain results from activity in neural pathways caused by actual tis...

Introduction: Ginger has shown anti-nociceptive effects. Here we investigated the possible involvement of GABAA receptors in anti-nociceptive effect of ginger using muscimol (GABAA agonist) and picrotoxin (GABAA antagonist) in rats that received ginger. The pain sensitivity was evaluated by formalin test. Methods: Thirty-five male Sprague-Dawley rats were randomly divided into 7 groups (n=5): s...
