摘要 目的探讨P糖蛋白抑制剂红霉素对P糖蛋白介导的大鼠吗啡耐受效应的逆转作用。方法雄性SD大鼠随机分为3组,A组:皮下注射吗啡10 mg/kg,30 min后腹腔注射10 mL/kg的生理盐水;B组:皮下注射吗啡10 mg/kg,30 min后腹腔注射75 mg/kg红霉素;C组:皮下注射10 mL/kg的生理盐水,30 min后腹腔注射10mL/kg的生理盐水;测定大鼠吗啡耐受形成的最大镇痛百分率(MPE),采用免疫组化方法测定P糖蛋白免疫反应阳性产物在吗啡耐受过程中的变化。结果 A组第1天的MPE为100%,第3天和第5天分别下降到(79.50±26.16)%和(59.50±27.58)%,到第7天已经下降至(23.20±17.22)%,与第1天比较差异有统计学意义(P<0.05);B组第1天的MPE为100%,第3天的MPE为(91.00±12.73)%,第5天的MPE为(65.00±8.49)%,第7天的MPE为(57.00±11.31)%。A组第7天P糖蛋白阳性面积为(0.80±0.06)%,与C组[(0.53±0.08)%]比较,差异有统计学意义(P<0.05),B组第7天P糖蛋白阳性面积为(0.54±0.02)%,与A组比较差异有统计学意义(P<0.05)。结论红霉素作为P糖蛋白抑制剂可逆转P糖蛋白介导的吗啡耐受效应。
