title: Effect of cortisone, aldosterone and nialamide on "amphetamine stereotypies" and brain methamphetamine levels of adrenalectomized rats.
abstract: Cortisone, aldosterone or nialamide was administered to adrenalectomized or sham-operated rats for 7 days, and methamphetamine was injected 24 hrs after the last injection of these compounds. Stereotyped head movement and licking activity were scored 5 min, 30 min and 60 min after methamphetamine injection and, in parallel brain methamphetamine levels in similarly treated rats were measured 5 min, 30 min and 60 min after the methamphetamine injection. Adrenalectomy depressed stereotyped head movements but enhanced the brain amphetamine accumulation. Nialamide but not the hormones further increased the amphetamine accumulation in adrenalectomized rats. No drugs had any effect on the amphetamine-induced head movement suppressed by adrenalectomy.
