腹膜内施用κ-阿片受体激动剂布马佐辛、替氟多和U-50,488 H对吗啡(8 mg/kg腹膜内)的作用。使用甩尾试验测定未用过吗啡和吗啡耐受的雄性Sprague-Dawley大鼠的诱导镇痛。用皮下注射法诱导大鼠吗啡耐受,在7天期间植入6个吗啡丸。植入吗啡颗粒导致耐受性的发展,如与植入安慰剂颗粒的大鼠相比,对吗啡的镇痛反应降低所证明的。布马佐辛(0.3,1.0和3.0 mg/kg)和U-50,488 H(16 mg/kg)可拮抗吗啡诱导的大鼠镇痛作用,而替氟多(8和16 mg/kg)可增强这种作用。在吗啡耐受大鼠中,布马佐辛(3 mg/kg)和U-50,488 H(16 mg/kg)增强吗啡诱导的镇痛作用。在吗啡耐受大鼠中,任何剂量的替氟安定对吗啡诱导的镇痛作用均无影响。这些结果提供了证据,表明不同的κ-阿片受体激动剂对吗啡初治大鼠和吗啡耐受大鼠中吗啡诱导的镇痛作用有差异。
The effect of i.p. administration of κ-opioid receptor agonists, bremazocine, tifluadom and U-50,488H on morphine (8 mg/kg i.p.)-induced analgesia in morphine-naive and morphine tolerant male Sprague-Dawley rats was determined using the tail-flick test. The tolerance to morphine in the rats was induced by s.c., implantation of six morphine pellets during a 7-day period. Implantation of morphine pellets resulted in the development of tolerance as evidenced by the decrease in the analgesic response to morphine when compared to placebo pellets implanted rats. Bremazocine (0.3, 1.0 and 3.0 mg/kg) and U-50,488H (16 mg/kg) antagonized morphine-induced analgesia in morphine-naive rats while tifluadom (8 and 16 mg/kg) potentiated the effect. In morphine-tolerant rats, bremazocine (3 mg/kg) and U-50,488H (16 mg/kg) potentiated morphine-induced analgesia. Tifluadom at any of the doses had no effect on morphine-induced a analgesia in morphine-tolerant rats. These results provide evidence that different κ-opioid agonists modify morphine-induced analgesia differentially in morphine-naive and morphine-tolerant rats.
