مقدمه: مطالعات زیادی نشان می دهند تجویز حاد و مزمن دگزامتازون دارای اثرات پر دردی و ضد التهابی می باشد و استرس نیز اثرات متفاوتی چون بی دردی،پردردی و ضد التهابی را نشان می دهد اما این اثرات بر روی nociceptionدرغیاب فیبر های cکار نشده است. در مطالعه حاضر نقش فیبرهای c در اثرات بی دردی(analgesic )، پردردی(hyperalgesic )، التهابی(proinflammatory ) و ضدالتهابی(anti-inflammatory ) دگزامتازون و استرس...
Background: Opioids like morphine produce side effects ranging from nausea and vomiting, pruritus, over sedation, dizziness and urinary retention to respiratory depression. Particularly, on chronic administration, it leads to development of tolerance. Combining opioids with certain other drugs (adjuvant analgesics) like ketamine, which is an N-methyl-D-aspartate (NMDA) receptor antagonist, not ...
The action mechanism for the production of spinal analgesia of KK-3, tyrosyl-N-methyl-gamma-aminobutylyl-phenylalaninol, was examined by the tail pinch and tail flick methods. Intrathecal KK-3, 2.5, 5 and 10 nmol/mouse, dose-dependently produced an analgesic effect in both methods. In the tail pinch method, the analgesia was suppressed by 2 mg/kg but not by 1 mg/kg of naloxone; however, the ana...
We have studied the effects of three different types of calcium channel blockers (verapamil, diltiazem, and nicardipine) on local lignocaine sensory block. The standardized tail flick test was used to measure the duration and degree of lignocaine-induced conduction block in rats. After obtaining baseline tail flick latencies (mean 3.2 s), two 100-microliter doses of 0.3% lignocaine alone, a com...
This study investigated the antinociceptive mechanisms of khat extract (100, 200, and 400 mg/kg, i.p.) in four pain models: two thermic (hot plate, tail-flick) and two chemical (acetic acid, formalin) models. Male mice were pretreated intraperitoneally (i.p.) with the opioid receptor blocker naloxone (5 mg/kg), the cholinergic antagonist atropine (2 mg/kg), the selective α1 blocker prazosin (1 ...
BACKGROUND The combination of two analgesic agents offers advantages in pain treatment. Codeine and morphine analgesia is due to activation of opioid receptor subtypes. METHODS This study, performed in mice using isobolographic analysis, evaluated the type of interaction in intraperitoneal (ip) or intrathecal (it) coadministration of codeine and morphine, in three nociceptive behavioral model...
a b s t r a c t introduction: aloe vera extract is used as an anti-inflammatory and anti-bradikinin agent in laboratory animals. the aim of this survey was to evaluate the ant-nociceptive effect of a. vera aqueous extract in fructose-fed male rats. methods: forty-five wistar-albino male rats were equally and randomly divided into five groups including sham operated and four test groups. sham op...
The limbic system has been implicated in the modulation of pain. The aim of this study was to determine the role of amygdala in different types of pain, viz., phasic and tonic. Unilateral stimulation of central nucleus of amygdala (CeA), basolateral nucleus (BL) and medial amygdaloid (MeA) in conscious rats resulted in the reduction of the tonic formalin-induced pain. The thresholds for simple ...

cuminum cyminum linn. (umbelliferae) is a plant, which has been used as a toothache remedy in folk medicine of iran. in this study, the potential anti-nociceptive and anti-inflammatory activities of the fruit essential oil of c. cyminum has been evaluated in chemical (formalin test) and thermal (tail-flick test) models of nociception and formalin model of acute inflammation in rats and mice. th...
