Rats treated with Lilly 110140, a specific inhibitor of serotonin re-uptake in brain, are less sensitive to electroshock. Lilly 110140 antagonizes the hyperalgesia following injections of p-chlorophenylalanine and potentiates morphine analgesia. Naloxone blocks the analgesia following morphine, but has no effect on Lilly 110140-induced analgesia. Brain serotonin neurons may, at least in part, mediate analgesia.
用Lilly 110140(一种大脑中血清素再摄取的特异性抑制剂)处理的大鼠对电击的敏感性较低。Lilly 110140可拮抗注射对氯苯丙氨酸后的痛觉过敏,并增强吗啡镇痛作用。纳洛酮可阻断吗啡后的镇痛作用,但对Lilly 110140诱导的镇痛作用无效。大脑血清素神经元可能至少部分介导了镇痛作用。
