中文摘要:
      选取中华圆田螺为受试动物,探究氟对其肝胰脏抗氧化酶SOD、GSH、POD活性和丙二醛(MDA)含量的影响。结果显示,在不同浓度水氟环境条件下(0、40、80、160 mg L-1)连续暴露10 d、20 d和30 d时,与对照组相比,中华圆田螺肝胰脏SOD活性在暴露前20 d,中低浓度组活性被诱导升高,高浓度组受抑制降低。暴露30 d时,中低浓度组活性降低,高浓度组逐渐升高。MDA含量在暴露前20 d时,中低浓度组活性整体被诱导升高,高浓度组受抑制降低。暴露30 d时,MDA含量受到显著抑制均低于对照组。GSH活性以诱导为主均高于对照组,POD活性在10 d时均低于对照组,而在20 d时被诱导升高且均高于对照组,30 d时中高浓度以抑制为主。上述研究结果为水质污染控制及生态风险评价提供了基础数据。

英文摘要:
      The effects of fluoride on the activities of antioxidant enzymes (SOD, GSH and POD) and MDA levels were measured in hepatopancreas of Cipangopaludina cahayensis exposed to different concentrations of fluoride (0, 40, 80, 160 mg L-1) for 30 days. The results indicated that compared with the control group, SOD activities were induced in the low concentration group but were inhibited in the high concentration group after 20 days exposure. After exposure for 30 days, SOD activities were decreased in hepatopancreas of Cipangopaludina cahayensis exposed to low and medium concentration fluoride, while were gradually increased in high concentration group. MDA contents were induced in the hepatopancreas of Cipangopaludina cahayensis exposed to low and medium concentrations while were inhibited in the high concentration group for 20 days. After exposure for 30 days, the MDA contents were significantly inhibited compared with that in the control group. GSH activities were higher in the hepatopancreas of Cipangopaludina cahayensis during the whole exposure period. POD activities were decreased compared with those in the control group after 10 days exposure, and then were elevated after 20 days exposure, while were inhibited after 30 days exposure. All the results would provide the basic data for water pollution control and ecological risk assessment.
