Background: Musculoskeletal pain is a major clinical problem, but researchers lack viable animal models to study this phenomenon. However, formalin injections are widely used to produce tonic and neurogenic nociceptive responses in rodents. Rodents can present a potential animal model for pain. Objectives: To develop a muscle pain model with intramuscular injection of formalin in rats. Ma...
BACKGROUND We investigated the effects of pre-emptive administration of ketamine and norBNI on pain behavior and the expression of DREAM, c-Fos, and prodynorphin proteins on the ipsilateral side of the rat spinal cord at 2 and 4 hours after formalin injection. METHODS Eighty-four male Sprague Dawley rats were divided into 4 major groups consisting of control rats (C) (n = 12), rats given only...
BACKGROUND Pregabalin is an anticonvulsant and analgesic agent that interacts selectively with the voltage-sensitive-Ca(2+)-channel alpha-2-delta subunit. The aim of this study was to evaluate whether the analgesic action of intrathecal (IT) pregabalin is associated with K(ATP) channels in the rat formalin test. METHODS IT PE-10 catheters were implanted in male Sprague-Dawley rats (250-300 g)...
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 a biphasic pattern (first phase: 0-5 min and second phase: 15 - 60 min) of licking/biting an...
Background: Studies have emphasized the effect of Trigonella foenum-graecum extract on the reduction of pain and inflammation. Objective: In this research we investigated the mechanisms of Trigonella foenum-graecum extract in reducing pain and inflammation induced by formalin. Methods: Male Albino mice (weight 20 - 25 g) were evaluated through the injection of 2 microliters of formalin to th...
