چکیده

In this study, the antinociceptive effects of the gap junction blocker carbenoxolone and morphine were examined using the formalin test as a model of pain. We found that carbenoxolone was dose-dependently antinociceptive in both the first and second phases of the formalin test. Pretreatment with carbenoxolone increased antinociceptive effect of morphine in the first phase of formalin test. Also, pretreatment of carbenoxolone at lower dose of morphine could enhance antinociceptive effect of it in the second phase of formalin test. It is possible that gap junction blockade may be involved in the antinociceptive activity of carbenoxolone.

Gap junctions of the hippocampal CA1 area are crucial for memory consolidation

Introduction: Gap junctions are specialized cell–cell contacts between eukaryotic cells through which they communicate. This type of communication has the potential to modulate memory process. We evaluated the effects of the gating of the hippocampal CA1 area gap junction channels on memory consolidation, using passive avoidance task. Materials and Methods: 72 adult male Wistar rats were distri...

Effects of intrathecal carbenoxolone treatment on nociception and analgesia in rat.

BACKGROUND Gap junctions (GJ) are important in pain signalling at the spinal cord level. AIMS The aim of this investigation was to study the effects of GJ on nociception and the analgesic/hyperalgesic effects of morphine following administration of carbenoxolone as a GJ blocker. Male Wistar rats (200-250 g) were divided into three groups: saline i.p., 10 mg/kg and 1 μg/kg i.p. morphine, each ...

A Study on the Effect of Intracuneiformis Nucleus Microinjection of GABAA Receptor Agonist and Antagonist on Antinociceptive Effects of Morphine by Formalin Test in Rat

In the present study, the effects of intracuneiformis nucleus microinjection of gamma-aminobutyric acidA (GABAA) receptor agonist and antagonist on antinociception inducced by morphine were investigated with formalin test in rat. Intracuneiformis nucleus microinjection of morphine (10µgr/rat) and Bicuculline (50, 100 ng/rat) induced antinociception in the both first and second phases of formali...

Long-term Morphine-treated Rats are more Sensitive to Antinociceptive Effect of Diclofenac than the Morphine-naive rats

This study investigates the effectiveness of the antinociceptive effects of diclofenac, an NSAID, on the nociceptive behavior of morphine-treated rats on formalin test.Rats were treated with morphine-containing drinking water for twenty one days, which induced morphine dependence. The antinociceptive effects of 8, 16, and 32 mg/kg doses of diclofenac were then evaluated and compared with distil...
