In this study, we investigated the role of orexinergic systems in dopamine-related behaviors induced by the mu-opioid receptor agonist morphine in rodents. Extensive coexpression of tyrosine hydroxylase with orexin receptors was observed in the mouse ventral tegmental area (VTA). The levels of dopamine and its major metabolites in the nucleus accumbens were(More)
We recently reported that micro-opioid receptor agonist morphine failed to induce its rewarding effects in rodents with sciatic nerve injury. In the present study, we investigated whether a state of neuropathic pain induced by sciatic nerve ligation could change the activities of the extracellular signal-regulated kinase (ERK) and p38 in the mouse lower(More)
It has been widely accepted that repeated administration of kappa-opioid receptor agonists leads to the development of antinociceptive tolerance. The present study was designed to investigate the effect of repeated administration of a selective kappa-opioid receptor agonist (1S-trans)-3,4-dichloro-N-methyl-N-[2-(1-pyrrolidinyl)cyclohexyl]-benzeneacetamide(More)
Recently, it has been reported that both thrombin-sensitive protease-activated receptor 1 (PAR-1) and platelet-derived growth factor (PDGF) are present not only in platelets, but also in the CNS, which indicates that they have various physiological functions. In this study, we evaluated whether PAR-1/PDGF in the spinal cord could contribute to the(More)
The present study was designed to investigate the effect of repeated administration of a selective kappa-opioid receptor agonist (1S-trans)-3,4-dichloro-N-methyl-N-[2-(1-pyrrolidinyl)cyclohexyl]-benzeneacetamide hydrochloride [(-)U-50,488H] on antinociception and G-protein activation induced by mu-opioid receptor agonists in mice. A single s.c. injection of(More)

Pain is a multidimentional experience, generally most of chronic disease followed by pain incidence. Chronic pain can be caused by inflammation or neuropathic condition and change the imbalance of N-methyl-D-aspartate receptor 2B (NR2B) subunit. This research was an observation of the influence of gabapentin and baclofen to dorsal horn histology in(More)

Repeated treatment of morphine produces several change in brain and behavior that far outlast their initial neuropharmacological effects. The nature of persistent drug-induced neural plasticity is interested because it is thought to contribute to the development of drug dependency and addiction. The purpose of this study was designed to investigate the(More)
Multiple changes occur in the aging brain, leading to age-related emotional disorders. A growing body of recent evidence suggests that the cortical delta-opioid receptor system plays a critical role in anxiety- and depressive-like behaviors in the rodent. In this study, we show that aging mice promoted anxiety-like behaviors as characterized by both the(More)
The management of excessive adverse effects of opioids is a major clinical problem. The present study was undertaken to investigate the effect of a selective gamma-aminobutyric acid (GABA)(B) receptor agonist baclofen on the mu-opioid receptor agonist-induced antinociceptive, emetic and rewarding effects. Either morphine or fentanyl produced a(More)
The present study was designed to investigate the possible change in spinal micro -opioid receptor function after repeated administration of a selective kappa-opioid receptor agonist (1S-trans)-3,4-dichloro-N-methyl-N-[2-(1-pyrrolidinyl) cyclohexyl]-benzeneacetamide hydrochloride [(-)U-50,488H] in the ICR mouse. A single s.c. or i.t. injection of(More)
