Effects of cannabinoid compounds on neurons are predominantly mediated by the CB(1) cannabinoid receptor. Onset of signaling cascades in response to cannabimimetic drugs is triggered by the interaction of the cannabinoid receptor with G(i/o) proteins. Much work has been done to delineate the cannabinoid agonist-induced downstream signaling events; however,(More)
Aluminum, a known neurotoxin, has long been implicated in the pathogenesis of Alzheimer's disease. Its exposure is associated with impairment in the cholinergic system in the brain. In this study we investigated the behavioral effects of aluminum in rats and the possible effect of rivastigmine, a cholinesterase inhibitor, on the aluminum-induced behavioral(More)
We investigated the effect of rolipram, a selective phosphodiesterase IV inhibitor, on morphine dependence in mice. The withdrawal manifestations were significantly reduced in mice that were treated with rolipram in combination with morphine repeatedly, compared to the mice treated with morphine and saline. Immunohistochemical study of c-Fos protein(More)
We investigated how dizocilpine, a non-competitive N-methyl-D-aspartate (NMDA) receptor antagonist, affects the development of morphine dependence in mice. Co-administration of dizocilpine (0.25 mg/kg) and morphine (10 mg/kg) for 5 days attenuated the development of tolerance to the antinociceptive effects of morphine. The withdrawal manifestation induced(More)

PURPOSE The influence of N(6)-Cyclohexyladenosine (CHA), an adenosine A(1) agonist and 3-(2-Carboxypiperazine-4-yl)-1-propenyl-1-phosphonic acid (CPPene), a selective N-methyl-D-aspartate (NMDA) antagonist upon the anticonvulsant activity of diazepam (DA), sodium valproate (VP), diphenylhydantoin (DPH), phenobarbital (PB) and carbamazepine (CAZ) was(More)
Memantine, a noncompetitive NMDA receptor blocker, has been demonstrated to be neuroprotective against various neurotoxins. Aluminum, a well-known neurotoxin, has been suggested to be a contributing factor in Alzheimer's disease. In this study we investigated the possible effect of memantine on aluminum-induced cognitive impairment in rats. Rats were(More)
