Abstract

The antinociceptive effect of subcutaneous 4,5,6,7-tetrahydroisoxazol[5,4-c]pyridin-3-ol (THIP) or (+/-)-baclofen, measured as reaction time of rats placed on a plate heated to 55 degrees C, was assessed after a single or the last repeated (18 consecutive days) dose (5 mg kg-1 once daily) of subcutaneous desipramine. Baclofen (10 mg kg-1)-induced antinociception was reduced by acute and unaffected by chronic desipramine treatment. On the contrary, THIP (20 mg kg-1)-induced antinociception was unaffected by acute and reduced by chronic desipramine.

摘要

以置于加热至55摄氏度平板上的大鼠反应时间来衡量,在单次或最后一次重复(连续18天)皮下给予地昔帕明(每日一次,5 mg/kg)后,评估皮下注射4,5,6,7-四氢异恶唑并[5,4-c]吡啶-3-醇(THIP)或(±)-巴氯芬的抗伤害感受作用。急性给予地昔帕明可降低巴氯芬(10 mg/kg)诱导的抗伤害感受,而慢性给予地昔帕明则无影响。相反,急性给予地昔帕明对THIP(20 mg/kg)诱导的抗伤害感受无影响,而慢性给予地昔帕明则使其降低。
