在实验I中,A。82 mg/kg剂量的氢溴酸苯丙胺(AMP)在单向主动回避任务训练后立即ip,可增强24小时后测定的雄性ARS大鼠的保持能力。相比之下,AMP的剂量范围为。Ip 41-2.64 mg/kg不影响游泳逃逸任务的保持(实验II)。行为活跃的剂量。82 mg/kg可降低杏仁核和海马区的多巴胺浓度。给未经训练的SS(实验III)注射8.2 mg/kg的剂量可降低杏仁核、皮质、海马体、下丘脑和中脑中测得的去甲肾上腺素浓度;减少杏仁核、皮质、海马体和纹状体中的多巴胺浓度;并显著减少肾上腺髓质中去甲肾上腺素和肾上腺素的浓度。此外,由于肾上腺髓质的完整性对于AMP的增强作用是必要的,而且由于AMP降低了脑和肾上腺髓质中儿茶酚胺的浓度,这种药物可能通过对大脑和肾上腺髓质的双重作用而影响保留性能。
In Exp I, an. 82 mg/kg dose of 4-OH amphetamine hydrobromide (AMP) administered ip immediately following training in a 1-way active avoidance task enhanced retention performance of male ARS Sprague-Dawley rats measured 24 hrs later. In contrast, AMP in a dose range of. 41–2.64 mg/kg, ip, did not affect retention of a swim escape task (Exp II). The behaviorally active dose of. 82 mg/kg decreased dopamine concentrations in the amygdala and hippocampus. A dose of 8.2 mg/kg administered ip to naive untrained Ss (Exp III) decreased concentrations of norepinephrine measured in the amygdala, cortex, hippocampus, hypothalamus, and midbrain; decreased concentrations of dopamine in the amygdala, cortex, hippocampus, and striatum; and significantly reduced concentrations of norepinephrine and epinephrine in the adrenal medulla. In addition, because the integrity of the adrenal medulla is necessary for the enhancing action of AMP and because AMP reduces concentrations of catecholamines in the brain and adrenal medulla, it is possible that this drug affects retention performance by a dual action on the brain and the adrenal medulla.(20 ref)(PsycInfo Database Record (c) 2023 APA, all rights reserved)
