目的:研究熟大黄对大鼠肝脏的量-效/毒关系,探讨熟大黄保肝与损肝的“双向”作用及炮制减毒的客观真实性.方法:同时采用正常和病理动物,在较大剂量范围(生药2. 0,5. 4,14. 7,40. 0 g·kg~(-1)·d~(-1))考察熟大黄总提物对实验动物一般状态、生化指标和组织病理的影响,并通过因子分析方法综合分析熟大黄量-效/毒关系.结果:采用因子分析法从给药后显著变化的9个生化指标中抽提出2个公因子,公因子1主要由HA,LN和TGF-β_1主导,可解释为纤维化因子;公因子2主要由ALT,AST和ALP主导,可解释为细胞损伤因子.因子分析结果表明熟大黄对大鼠肝脏存在明显的药效与毒性“双向”作用:对CCl_4诱导的慢性肝损伤具...

OBJECTIVE: To investigate the dosage-efficacy/toxicity relationship of prepared rhubarb, in order to explore the bidirectional effects in hepatoprotection and hepatotoxicity of prepared rhubarb and the objective authenticity for attenuating toxicity by processing. METHOD: Normal and pathological animals were adopted simultaneous to investigate the effect of total extracts from prepared rhubarb within a high dose range (2.0, 5.4, 14.7, 40.0 g x kg(-1) x d(-1)) on normal state, biochemical index and histopathology of experimental animals. The factor analytic approach was used to analyze the dosa...
