Propranolol blocks the unconditioned and conditioned hyperactive effects of methamphetamine in CD-1 mice.
The present experiment examined the contribution of the β-adrenergic receptor system in mediating the unconditioned (i.e. pharmacological) and conditioned (i.e. learned) hyperactive effects of methamphetamine. To this end, mice underwent an 8-day conditioning procedure involving two different, alternating session types (chamber and home-cage days). On chamber days (1, 3, 5, and 7), mice were injected (intraperitoneally) with vehicle (dH 2 O) or propranolol (16 or 32 mg/kg) and were injected (subcutaneously) 30 min (min) later by either vehicle (saline; unpaired) or methamphetamine (1.0 mg/kg; paired). On home-cage days (2, 4, 6, and 8), mice were injected (subcutaneously) with either vehicle (saline; paired) or methamphetamine (1.0 mg/kg; unpaired) in their home cages. The test day for conditioned hyperactivity occurred 48 h after the last chamber day. Propranolol dose-dependently blocked the unconditioned and conditioned hyperactive effects of methamphetamine, implicating a role for the β-adrenergic system in mediating these effects of methamphetamine.
期刊介绍:
Behavioural Pharmacology accepts original full and short research reports in diverse areas ranging from ethopharmacology to the pharmacology of schedule-controlled operant behaviour, provided that their primary focus is behavioural. Suitable topics include drug, chemical and hormonal effects on behaviour, the neurochemical mechanisms under-lying behaviour, and behavioural methods for the study of drug action. Both animal and human studies are welcome; however, studies reporting neurochemical data should have a predominantly behavioural focus, and human studies should not consist exclusively of clinical trials or case reports. Preference is given to studies that demonstrate and develop the potential of behavioural methods, and to papers reporting findings of direct relevance to clinical problems. Papers making a significant theoretical contribution are particularly welcome and, where possible and merited, space is made available for authors to explore fully the theoretical implications of their findings. Reviews of an area of the literature or at an appropriate stage in the development of an author’s own work are welcome. Commentaries in areas of current interest are also considered for publication, as are Reviews and Commentaries in areas outside behavioural pharmacology, but of importance and interest to behavioural pharmacologists. Behavioural Pharmacology publishes frequent Special Issues on current hot topics. The editors welcome correspondence about whether a paper in preparation might be suitable for inclusion in a Special Issue.
