摘要 【目的】研究银杏叶提取物对大鼠肝脏细胞色素 P450酶 CYP1A1、CYP1A2、CYP2B1/2、CYP3A1蛋白表达的影响。【方法】银杏叶提取物10mg/kg 和100mg/kg 两个剂量,大鼠经灌胃处理10d 后,取出肝脏,称重,制备肝微粒体,以未经处理者为对照组,测定 CYP1A1、CYP1A2、CYP2B1/2、CYF3A1的蛋白表达。【结果】CYP1A1、CYP1A2、CYP2B1/2、CYP3A1的蛋白表达在给药后比对照组显著升高,且存在明显的剂量依赖性。【结论】银杏叶提取物能显著诱导大鼠CYP1A1、CYP1A2、CYP2B1/2、CYP3A1的蛋白表达水平,故有可能影响与之同时服用的药物的疗效。
