Mechanism of d-amphetamine inhibition of protein synthesis

Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1976
At 1 h after intraperitoneal administration of D-amphetamine sulphate (15 mg/kg), rat brain polyribosomes show disaggregation accompanied by reduced capacity for in vitro peptide chain elongation. The direct action of amphetamine on cell-fine protein-synthesizing systems was therefore explored. When brain or liver polyribosomes from untreated rats were

Effects of d-amphetamine upon psychosocial stress responses

Journal of Psychopharmacology, 2016
Psychostimulant drugs alter the salience of stimuli in both laboratory animals and humans. In animals, stimulants increase rates of responding to conditioned incentive stimuli, and in humans, amphetamine increases positive ratings of emotional images. However, the effects of stimulants on real-life emotional events have not been studied in humans.

Modulation of use‐dependent plasticity by d‐amphetamine

Annals of Neurology, 2001
AbstractUse‐dependent plasticity, thought to contribute to functional recovery after brain injury, is elicited by motor training. The purpose of this study was to determine if administration of d‐amphetamine facilitates the effects of motor training on use‐dependent plasticity.

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.

d-Amphetamine, operant history, and variable-interval performance

Pharmacology Biochemistry and Behavior, 1980
The effects of d-amphetamine on the bar-pressing of rats maintained under a variable-interval schedule of water reinforcement were examined as a function of the operant history of the subjects. One group of rats initially received 51 sessions of exposure to a fixed-ratio 20 schedule, while a second group received equivalent exposure to an interresponse-

d-amphetamine and adjunctive drinking in rats

Psychopharmacology, 1977
In the first experiment four food-deprived rats developed high levels of adjunctive water drinking during daily sessions of intermittent food pellet delivery. When the water was removed and a solution of d-amphetamine sulfate (0.01 mg/ml) put in its place, adjunctive drinking was disrupted towards the end of each session although the rats ingested ...

Cocaine Choice in Humans During d-Amphetamine Maintenance

Journal of Clinical Psychopharmacology, 2010
The results of preclinical laboratory experiments and clinical trials indicate that agonist replacements such as d-amphetamine may be a viable option for managing cocaine dependence. This study determined the effects of d-amphetamine maintenance on cocaine choice behavior in human participants.

Effects of d-amphetamine on human aggressive behavior

Psychopharmacology, 1986
Male research subjects were administered placebo and three doses of d-amphetamine (5, 10 and 20 mg/70 kg) in a laboratory situation which provided both aggressive and non-aggressive response options. The non-aggressive response was button pressing maintained by presentation of points exchangeable for money at the end of the session.

Aggression in Hyperactive Boys: Response to d-Amphetamine

Journal of the American Academy of Child Psychiatry, 1984
Ten hyperactive boys were studied in a double-blind, placebo-counterbalanced trial of d -amphetamine. On the basis of reports citing the aggression-reducing effect of low doses of d -amphetamine in animals and adults, it was predicted that the study group's aggressive behavior and aggressive/impulsive attitudes and fantasies would be lower in the d -

Drug preference and mood in humans: d-amphetamine

Psychopharmacology, 1980
A total of 31 normal human volunteers participated in a nine-session experiment. During the first four sessions, they received alternately 5 mg d-amphetamine or placebo. During the next five sessions, they were given a choice between amphetamine and placebo.
