摘要
目的 研究脊髓NMDA受体在吗啡耐受过程中的变化 ,旨在探讨NMDA受体在吗啡耐受机制中的作用 ,为进一步阐明吗啡耐受的受体机制提供实验材料。方法 建立慢性吗啡耐受大鼠模型 ,用MK 80 1进行干预 ,用免疫组织化学方法测定脊髓后角NMDA受体在吗啡耐受过程中的变化 ,MK 80 1抗吗啡耐受过程中是否对NMDA受体数量有影响。结果 吗啡耐受形成过程中NMDA受体数量增加 ;MK 80 1与吗啡合用有抗吗啡耐受作用 ,MK 80 1可以阻断吗啡耐受过程中NMDA受体数量的增加。结论 吗啡耐受的机制可能涉及NMDA受体的上调 ,MK 80 1可能通过抑制NMDA受体上调而具有部分抗吗啡耐受作用。
