摘要: Several drug discrimination studies reported that both competitive and uncompetitive NMDA receptor antagonists substituted for ethanol stimulus in rats. In the present study we examined if compounds act as agonists at complex, D-cycloserine (a partial agonist glycine positive modulatory site) N-methyl-D-aspartate (an glutamate binding site), could antagonize discriminative effects of ethanol. Rats were trained to discriminate between IP administered 1.0 g/kg (10% v/v) saline under a sweetened milk-reinforced fixed ratio 10 (FR10) schedule reinforcement. When animals met criteria, antagonism tests conducted with (0.3-10.0 mg/kg, IP) (15.0-60.0 IP). Neither nor antagonized ethanol-mediated effects. addition, (3.0-300.0 did not substitute These results indicate least certain complex do attenuate interoceptive cue rat.
