Differential effects of nicotine but not cathinone on motor activity of P and NP rats.

The locomotor stimulatory effects of nicotine (0.4 and 0.8 mg/kg) and cathinone (0.5 and 1.0 mg/kg) were assessed in alcohol-preferring (P) and -nonpreferring (NP) rats. Whereas P rats demonstrated enhanced (0.8 mg/kg) or no change (0.4 mg/kg) in…

Discriminative stimulus properties of (+)cathine, an alkaloid of the khat plant.

The effects of the psychostimulant (+)cathine (norpseudoephedrine) were examined in a two-choice, food-motivated, drug-discrimination paradigm. Rats were able to discriminate cathine from vehicle and this effect was dose- and time-dependent. Prior…

Effects of cathinone and amphetamine on the neurochemistry of dopamine in vivo.

The effects of (-)cathinone, the primary psychoactive alkaloid of the Khat plant, were compared to those of (+)amphetamine in the anterior caudate-putamen and the nucleus accumbens. In vivo microdialysis was used to measure extracellular levels of…

Effect of altering dopamine or serotonin neurotransmitters upon cathinone discrimination.

Rats were trained to discriminate between the stimulus properties of 0.8 mg/kg l-cathinone and its vehicle in a two-lever, food-motivated operant task. Once trained, rats showed a dose-related decrease in discriminative performance when tested with…

Effect of learned behavior upon conditioned place preference to cathinone.

The purpose of this study was to examine whether first training rats to discriminate the stimulus cues produced by an indirect dopamine agonist, cathinone, would influence a subsequent test of preference. The conditioned place preference (CPP)…

Potentiation of cathinone by caffeine and nikethamide.

The drug discrimination paradigm was employed to evaluate the effect of coadministration of both caffeine and nikethamide upon the discrimination of a low dose of cathinone. In rats trained to discriminate between 0.8 mg/kg l-cathinone and its…

Rats become acutely tolerant to cathine after amphetamine or cathinone administration.

The drug discrimination paradigm was used to evaluate in rats the ability of the discriminate response to either 0.8 mg/kg d-amphetamine or 0.8 mg/kg l-cathinone to generalize to 2.4-6.0 mg/kg of the active cathinone metabolite d-norpseudoephedrine,…

Effect of repeated administrations upon cathinone discrimination and conditioned place preference.

1. Eight male rats were trained to discriminate the interoceptive cues produced by 0.8 mg/kg l-cathinone in a two-lever, food-motivated operant task and they were, subsequently, tested for preference to cathinone in a conditioned place preference…
