中文摘要：以鲫鱼为实验对象,采用不同质量浓度的LAS和Cd2+进行暴露实验,研究亚急性条件下,LAS、Cd2+及其复合污染对鲫鱼鳃、肝脏SOD、Na+-K+-ATPase活性的影响.结果表明:在单一LAS、Cd2+处理条件下,随LAS、Cd2+质量浓度增加,鲫鱼鳃、肝脏的SOD、Na+-K+-ATPase活性与对照组相比均呈浓度-效应关系;复合处理下,污染物质量浓度的不同组合对鲫鱼鳃、肝脏的SOD、Na+-K+-ATPase活性影响不同,其中当Cd2+质量浓度为0.4mg.L-1时,肝脏的SOD、Na+-K+-ATPase活性均随LAS质量浓度的增加而降低,各复合组的SOD、Na+-K+-ATPase活性均显著低于相应质量浓度的单一Cd2+处理组(P<0.05);2.0 mg.L-1Cd2+与5.0 mg.L-1LAS复合组鲫鱼鳃SOD、Na+-K+-ATPase活性、肝脏SOD活性显著低于相应质量浓度的单一Cd2+、LAS处理组(P<0.05).在一定质量浓度的组合下,LAS与Cd2+复合污染在SOD、Na+-K+-ATPase水平上表现为一定的协同作用.

外文摘要：The effects of LAS, Cd2＋ alone and combined pollution on the activities of SOD and Na＋-K＋- ATPase in the gill and liver tissues of Carassius auratus stressed for 14 days were studied in concentrations of LAS （1.0mg·L^-1,5.0 mg·L^-1） and Cd2＋（0.4 mg. L-1,2.0 mg. L^-1） by using exposed experiment. The results showed that, compared with control, the dose-effect was observed under alone pollution both in the liver and gill. Different pollution combined treatments produced different effects in changes of two enzymes activities in the liver and gill. Thus, 0. 4 mg · L^-1 Cd2＋ induced the SOD and Na＋-K＋-ATPase activities decreased with the increase of LAS concentration, and the activities of two enzymes in the liver were lower under combined stress than that of Cd2＋ treatment alone significantly （P〈0. 05）, while 2.0 mg· L-1 Cd2＋ and 5.0 mg·L^-2 LAS induced the SOD and Na＋-K＋-ATPase activities in the gill and the SOD activity in the liver decreased significantly （P〈0. 05） compared with the Cd2＋ or LAS treatment aone. It can be concluded that the joint effects of the combined pollution on the SOD and Na＋-K＋-ATPase activities were synergistic under certain LAS and Cd2＋ concentrations.
