Abstract

Rats were administered either amitriptyline (20 mg kg-1, i.p.) or mianserin (10 mg kg-1, i.p.) for 21 consecutive days and the alpha- and beta-adrenoceptor characteristics of cardiac ventricles, cerebral cortex and hippocampus examined by ligand-binding procedure. Chronic administration of amitriptyline significantly reduced the maximum density of beta-receptors in the cerebral cortex without significantly altering cardiac alpha- or beta-receptors; mianserin treatment had no significant effect on any of the receptors studied.

摘要

给大鼠连续21天腹腔注射阿米替林(20毫克/千克)或米安色林(10毫克/千克),然后通过配体结合法检测心室、大脑皮层和海马体的α-和β-肾上腺素能受体特征。长期给予阿米替林可显著降低大脑皮层中β-受体的最大密度,而对心脏的α-或β-受体无显著影响;米安色林处理对所研究的任何受体均无显著影响。
