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)

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)
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)
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)
Some possible biological and biochemical effects of Sistrurus Malarius Barbouri (SMB) crude venom were investigated. The acute median lethal doses of the venom under investigation were found to be 14.4 and 9.72 microg/g body weight (b.w.), respectively, in rats on i.p. administration. The possible neurotoxicity of acute, subchronic and chronic doses was(More)
It is generally accepted that divalent cations are involved in the nociceptive pathway. The effect of systemic co-administration of magnesium sulfate and calcium channel blockers (nifedipine, verapamil) on the analgesic effect of opioid (mixed mu/kappa: butorphanol) and non-opioid drugs (paracetamol) was investigated. Albino mice and rats were used as(More)
