摘要 采用体外肝微粒体酶生化测定方法,研究地塞米松(DEX)和利福平(RFP)对鸡细胞色素P450酶系的影响。将36羽公鸡随机等分为对照组(生理盐水)、DEX处理组(5 mg.kg-1,腹腔注射7 d)和RFP处理组(15 mg.kg-1,口服7 d),第8天处死实验动物,提取肝微粒体,进行微粒体酶活性分析。结果显示:与对照组相比,DEX组相对肝重、肝微粒体蛋白浓度、细胞色素P450总含量和红霉素-N-脱甲基酶(ERND)的活性均显著升高(P<0.01),而RFP组各项指标没有统计学意义(P>0.05)。结果提示:腹腔注射地塞米松对鸡肝CYP450产生明显诱导作用,口服给予利福平对鸡肝CYP450无明显诱导作用。
