1、万方数据中文摘要2癃闭舒对大鼠肝脏CYP各亚型蛋白质表达水平的影响。大鼠灌胃给予癃闭舒两个月后,与对照组相比,癃闭舒组大鼠肝脏CYPlAl、CYPlA2、CYP2C11、CYP2D1、CYP3A1的蛋白质表达水平显著升高(P<0.01)。癃闭舒组大鼠肝脏CYPlAl、CYPlA2、CYP2C1l、CYP2D1和CYP3A1的蛋白质表达量与GAPDH蛋白表达量的比值分别为0.39+0.02、0.634-0.02、1.324-0.03、1.884-0.04和0.614-0.02。对照组大鼠肝脏CYPlAl、CYPlA2、CYP2C11、CYP2D1和CYP3A1的蛋白质表达量与GAPDH蛋白表达量
2、的比值分别为0.324-0.02、0.41:k0.01、1.084-0.05、1.56+0.02和0.44+0.01。与对照组相比,癃闭舒组大鼠肝脏CYP2E1的蛋白质表达水平显著降低(P<0.05)。给药组和对照组大鼠肝脏CYP2E1的蛋白质表达量与GAPDH蛋白表达量的比值分别为0.194-0.01和0.244-0.01。结论:1大鼠灌胃给予抗良性前列腺增生药癃闭舒两个月后,大鼠肝脏CYPlA2、CYP281、CYP2C1l、CYP2E1、CYP3Al和CYP3A2亚型的mRNA表达水平显著升高。2大鼠灌胃给予抗良性前列腺增生药癃闭舒两个月后,大鼠肝脏CYP2E1的蛋白表达水平显著降低;大
