Reversal of adenine-induced depression of mouse locomotor activity by amphetamine.
Adenine (200 mg/kg) was found to depress locomotor activity in mice. Dl-, and d-amphetamine reversed the depression of locomotor activity produced by adenine while l-amphetamine was found to be incapable of reversing the adenine-induced depression. The stimulation of mouse locomotor activity caused by dl- and d-amphetamine in mice treated with adenine was less than that caused by equal dosage of these agents in mice not treated with adenine. Mice treated with adenine showed marked depletion of brain norepinephrine, dopamine and serotonin, irrespective of whether or not they had been treated with d- or l-amphetamine, and whether or not these agents were capable of reversing adenine-induced depression of locomotor activity.
