Prior exposure to MK-801 sensitizes rats to ethanol-induced conditioned taste aversion.

چکیده
Pretreatment with an uncompetitive NMDA receptor antagonist, dizocilpine [(+)MK-801; six daily injections of 0.1 or 0.2 mg/kg, i.p.] significantly enhanced subsequent 1.5 g/kg ethanol-induced conditioned taste aversion (CTA). In a control experiment, dizocilpine (0.05-.2 mg/kg) produced only a marginal CTA. Thus, pre-exposure to low, non-aversive doses of MK-801 may sensitize rats to the aversive stimulus effects of ethanol.

متن کاملThe delayed effects of DTG and MK-801 on latent inhibition in a conditioned taste-aversion paradigm.
The delayed effects of phencyclidine (PCP) have been shown to disrupt latent inhibition (LI) in a conditioned taste-aversion paradigm. In an attempt to understand the mechanism of this disruption, the delayed effects of the selective sigma receptor agonist 1,3-Di(2-tolyl)guanidine (DTG) and the selective NMDA receptor antagonist MK-801 on latent inhibition were assessed in the same paradigm. Wa...
متن کاملEthanol-induced taste aversions: lack of involvement of acetaldehyde and the area postrema.
Two experiments were run to evaluate the role of acetaldehyde and the area postrema in the acquisition of an ethanol-induced conditioned taste aversion. An ethanol-induced taste aversion was observed in male Sprague-Dawley rats with a dose of 4 g/kg. PO, but not after doses of 1 or 2 g/kg. Pretreatment with 4-methylpyrazole (8 mg/kg, IP), which itself did not induce an aversion as compared to p...
متن کاملReversal Effect of Intra-Central Amygdala Microinjection of L-Arginine on Place Aversion Induced by Naloxone in Morphine Conditioned Rats
Background: Role of nitric oxide (NO) on expression of morphine conditioning using a solely classic task has been proposed previously. In this work, the involvement of NO on the expression of opioid-induced conditioning in the task paired with an injection of naloxone was investigated. Methods: Conditioning was established in adult male Wistar rats (weighing 200-250 g) using an unbiased procedu...
متن کاملNMDA receptors of dorsal hippocampus are involved in the acquisition, but not in the expression of morphine-induced place preference.
In the present study, involvement of the N-methyl-d-aspartate (NMDA) receptors of the CA1 region of dorsal hippocampus (intra-CA1) in the acquisition or expression of morphine-induced conditioned place preference in rats was studied. Male Wistar rats were used in these experiments. NMDA-receptor agonist (NMDA) and antagonist (MK-801) were injected into the CA1 region of the dorsal hippocampus (...
