To assess the potential effect of total flavonoids of epimedium （TFE） on cytochrome P450 and activity of its main isoforms in rat liver microsomes. TFE （300 mg/kg） was administered once daily to male Sprague-Dowley rats by gavage for fifteen days. The total cytochrome P450 content and its main isoforms CYP1A2, CYP3A4 and CYP2E1 activities in rat liver microsomes were detected. The activity of CYP1A2 was measured by fluorometry and the activities of CYP3A4 and CYP2E1 were determined by measuring the amount of methanal and p-aminophenol formed using UV/Vis spectrophotometer, respectively. Administration of TFE significantly increased the total CYP450 content and activities ofCYP1A2, CYP3A4 and CYP2E1 in rat liver microsomes, compared with the control group. Particularly, the activities of CYP1A2 and CYP2E1 were enhanced significantly （P〈0.01）. TFE induced the increase in total CYP450 content and its main isoforms CYP1A2, CYP3A4 and CYP2E1 activities in rat liver microsomes.
目的:比较帕罗西汀对单纯抑郁症和抑郁合并焦虑症的临床疗效。方法:采用前瞻性、多中心合作研究,所有病人均于每日早餐后服用20mg帕罗西汀。对180例资料完整的病人分别于治疗基期、治疗3个月和6个月时进行随访,并评价生活质量(quality of life,QOL)。结果:两组病人的QOL总评分和各维度评分随治疗时间延长而逐步升高,且抑郁合并焦虑症组的QOL改善情况优于单纯抑郁症组。结论:帕罗西汀能显著改善单纯抑郁症和抑郁合并焦虑症病人的QOL,使用足够疗程改善程度更大。
