Abstract

Liver microsomal glucuronidation of acetaminophen, chloramphenicol, salicylic acid, lorazepam, p-nitrophenol and morphine were measured in 8 days bile duct ligated rats. Compared to normals, cholestatic rats showed a decrease of 31% for p-nitrophenol glucuronidation; salicylic acid glucuronidation increased 281%; acetaminophen glucuronidation increased 38% while morphine, chloramphenicol and lorazepam values were similar to controls. We concluded that cholestasis produces non predictable changes on liver drug glucuronidation pathways.

胆汁淤积期肝药物糖醛酸化的变化是不可预测的。
观察胆管结扎大鼠8 d对乙酰氨基酚、氯霉素、水杨酸、劳拉西泮、对硝基酚和吗啡的肝微粒体糖醛酸化。与正常大鼠相比,胆固醇淤积大鼠对硝基酚葡萄糖醛酸化降低31%;水杨酸葡萄糖醛酸化增加281%;对乙酰氨基酚葡萄糖醛酸化升高38%,而吗啡、氯霉素和劳拉西泮值与对照组相似。我们的结论是,胆汁淤积对肝药物糖醛酸化途径产生不可预测的变化。
