OBJECTIVES The purpose of this work was to determine whether the intraperitoneal administration of glibenclamide as a K ATP channel blocker could have an effect on the antinociceptive effects of antidepressants with different mechanisms of action. METHODS Three antidepressant drugs, amitriptyline as a dual-action, nonselective inhibitor of noradrenaline and a serotonin reuptake inhibitor, flu...

Wu-tou decoction (WTD) is a classic traditional Chinese medicine formula and has been used effectively to treat joint diseases clinically. Previous reports indicated that WTD possesses anti-inflammatory activity; however, its actions on pain have not been clarified. Here, we investigated the antinociceptive activity of WTD in CFA-induced mice, and its possible mechanism of the action associated...

Background Vitex negundo L. has been widely studied for its beneficial effect in inflammatory and pain conditions. The present study describes the isolation of two new bioactive chromone constituents from V. negundo and their in vivo evaluation for anti-inflammatory and antinociceptive activities. Methods Two new chromone derivatives, namely, methyl 3-(2-(5-hydroxy-6-methoxy-4-oxo-4H-chromen-...

There are several reports that adenosine and carbamazepine have pharmacodynamic interaction. I n this study the antinociceptive interaction o f these two agents was evaluated in mice by the hot plate test. Agents were injected intraperitoneally. 0.2 and 0.4 mg/kg doses of R-phenylisopropyladenosine (R-PIA) substantially showed antinociceptive effects. Carbamazepine had antinociceptive acti...

BACKGROUND Amiloride has been reported to produce a wide variety of actions, thereby affecting several ionic channels and a multitude of receptors and enzymes. Intrathecal α2-adrenergic receptor agonists produce pronounced analgesia, and amiloride modulates α2-adrenergic receptor agonist binding and function, acting via the allosteric site on the α2A-adrenergic receptor. OBJECTIVES To investi...

BACKGROUND From the thousands of years, metal compounds have been used in medicine for treatment of various diseases including various types of cancers. Ruthenium was seen as a promising metal due to its similar kinetics to platinum and its lower toxicity. Therefore, we aimed to evaluate the newer mononuclear ruthenium (II) compounds for antinociceptive and antitumor activities. MATERIALS AND...

The therapeutic potential of snake venoms for pain control has been previously demonstrated. In the present study, the antinociceptive effects of Micrurus lemniscatus venom (MlV) were investigated in experimental models of pain. The antinociceptive activity of MIV was evaluated using the writhing, formalin, and tail flick tests. Mice motor performance was assessed in the rota rod and open field...

In Sri Lankan traditional medicine, the decoction of leaves of the plant Pongamia pinnata (L.) is claimed to possess antinociceptive activity. However, as yet, its antinociceptive potential has not been scientifically investigated. The aim of this study was to investigate the antinociceptive potential of an aqueous leaf extraction (ALE) of P. pinnata in rats, using three algesiometric methods (...

objective: this study was aimed to examine the antinociceptive and anti-inflammatory effects of urtica dioica leaf extract in animal models. materials and methods: hydroalcoholic extract of the plant leaves was prepared by percolation method. male swiss mice (25-35 g) and male wistar rats (180-200 g) were randomly distributed in control, standard drug, and three experimental groups (n=6 in each...

The mechanism of action of acetaminophen is currently widely discussed. Direct inhibition of cyclooxygenase isoforms remains the commonly advanced hypothesis. We combined behavioral studies with molecular techniques to investigate the mechanism of action of acetaminophen in a model of tonic pain in rats. We show that acetaminophen indirectly stimulates spinal 5-hydroxytryptamine (5-HT)1A recept...
