Abstract:
The influence of 6-hydroxydopamine on morphine-induced convulsions were investigated in rats. Morphine, in doses up to 100 mg/kg did not produce any convulsive pattern in vehicle-pretreated rats. The pretreatment of rats by 6-hydroxydopamine strongly potentiated the seizure producing activity of morphine and the dose-response curve of seizure severity shifted to the right. These results suggest that brain catecholamines are involved in the mechanism of morphine-induced convulsions.
