| 摘 要： | 为研究对苯二甲酸 (TPA)、乙二醇 (EG)、联苯 联苯醚 (DOW)对大鼠肝脏损伤的联合作用及其损伤机制 ,采用亚慢性动物实验 ,利用三因素两水平析因设计方法 ,分析研究了反映大鼠肝脏损伤的酶学、生化和形态学指标。结果表明 ,TPA、EG、DOW各联合染毒组大鼠的血清ALT活性和血清总胆汁酸 (TBA)含量 ,与单剂量染毒组及对照组相比均有不同程度的增高 ,析因分析结果提示 ,此 3种物质对肝脏损伤的联合作用特征表现为相加 (TPA +EG)、协同 (EG +DOW)、协同 (TPA +DOW)和相加作用 (TPA +EG +DOW) ,并通过形态学观察进一步得到验证。

| Abstract: | The joint injury actions and mechanisms of terephthalic acid (TPA), ethylene glycol (EG) and/or dowtherm A (DOW) on liver in rats were investigated. A subchronic toxicity study was designed by a 2(3) factorial method. Some enzymes, biochemical and morphologic indices reflecting the injury of liver were studied. The results showed that serum ALT and serum total bile acid (TBA) of rats in the combined intoxication groups were significantly higher than those in the groups with single toxic agent and control group. The results of factorial analysis showed that the joint action induced by TPA, EG and/or DOW were characterized as additive (TPA+EG), synergistic (EG+DOW), synergistic (TPA+DOW) and additive(TPA+EG+DOW)actions. The deduction was identified by morphologic observations. |
