Different effects of direct and indirect dopamine receptor agonists on immobility time in reserpine-treated mice.
1. The effects of dopamine agonists on the immobility time in mice were examined. 2. Apomorphine (APO), bupropion (BUP), bromocriptine (BRC) and quinpirole but not SKF 38393 elicited anti-immobility effect. The effect of the agonists was decreased by the D-2 antagonist sulpiride but not by the D-1 antagonist SCH 23390. 3. In animals pretreated with reserpine, the anti-immobility effects of APO and quinpirole were potentiated, while the response of BPU was decreased and that of BRC was not changed. 4. It is concluded that D-2 dopamine receptors are involved in the anti-immobility effects of dopaminergic agents, D-2 dopamine receptors may become hypersensitive by reserpine and BUP exerts its response through indirect dopaminergic if mechanism.
