摘要
The mu-opioid receptor subtypes involved in the discriminative stimulus properties of morphine were investigated in rats that had been trained to discriminate between 3.0 mg/kg morphine and saline. The discriminative stimulus properties of morphine were significantly attenuated by beta-funaltrexamine (an irreversible mu-opioid receptor antagonist: 10 and 20 mg/kg) and naloxonazine (an irreversible mu(1)-opioid receptor antagonist: 20 mg/kg). These results suggest that the discriminative stimulus properties of morphine may be mediated by mu(1)-opioid receptors.
