Female rats that rapidly acquire a d-amphetamine discrimination generalize more to d-amphetamine

Pharmacology Biochemistry and Behavior, 1996
Female Long-Evans rats were trained to discriminate d-amphetamine (0.8 mg/kg) vs. saline in a food-reinforced two-lever operant task. Fifteen rats (fast group) acquired the discrimination rapidly, achieving criterion (eight correct choices within ten sessions) during the first 10 sessions (mean sessions to criterion = 10.0).

Mechanism of the diuretic action of D-amphetamine

Metabolism, 1964
Abstract In a study of the mechanism of the diuretic action of D-amphetamine in idiopathic edema, it was found that D-amphetamine (20 mg.) significantly increased Na excretion both in normal subjects and in patients with idiopathic edema ingesting constant amounts of .14 per cent saline solution.

Self-administration of d-amphetamine by rats

Psychopharmacologia, 1968
Self-administration of d-amphetamine by rats was characterized by periods of drug intake and abstinence. Frequency of responding for drug injection was found to vary inversely as a function of drug dose per infusion (magnitude of reinforcement), and directly as a function of number of responses required per infusion (fixed-ratio reinforcement schedule).

Task-specific tolerance to d-amphetamine

Neuropharmacology, 1984
Rats were trained concurrently on sweetened-milk drinking and bar-press-responding behavior, which alternated on a daily basis. Dose-response functions for d-amphetamine were determined before and after conditions of chronic treatment. When given before chronic treatment, d-amphetamine decreased both milk consumption and reinforcement received for ...

Ganglionic blockade by d-amphetamine

European Journal of Pharmacology, 1983
The actions of d-amphetamine on ganglionic transmission in the isolated stellate ganglion of the hamster were observed. Blockade of the compound action potential by d-amphetamine had a slow onset with an onset half-time of 2-5 min. The concentration-blockade relationship for d-amphetamine was not shifted by phentolamine (10(-5) M) or propranolol (10(-6)

D-Amphetamine in obsessive-compulsive disorder

Psychopharmacology, 1983
In a double-blind crossover study, single doses of d-amphetamine and placebo were administered to 12 patients with severe chronic obsessive-compulsive disorder (OCD). Improvement of obsessional symptoms was significant on clinical ratings and was correlated with improved performance on an attention task.
