| 摘 要： | 以斑马鱼为受试材料,研究了Se(Ⅳ)和Se(Ⅵ)在斑马鱼组织中的累积及对抗氧化系统的影响。试验分3组,分别为对照组、Se(Ⅳ)处理组(500μg·L-1)和Se(Ⅵ)处理组(5000μg·L-1),处理28 d后,测定斑马鱼脑、鳃、肝、肠和肌肉组织中硒的累积以及过氧化氢酶(CAT)活性、总抗氧化能力(T-AOC)和Na+/K+-ATPase活性。结果显示,与对照组相比,硒处理组斑马鱼各组织中呈现不同程度的硒累积,肝组织中硒累积量最高,肠组织中CAT活性、鳃和肠组织中T-AOC活性以及鳃和肝组织中Na+/K+-ATPase活性均显著降低。Se(Ⅳ)与Se(Ⅵ)处理组相比,斑马鱼肝和鳃组织中硒累积量显著升高,肝组织中CAT活性显著下降13%,T-AOC活性显著升高1.8倍。研究结果表明Se(Ⅳ)比Se(Ⅵ)生物可利用性更高,硒累积导致斑马鱼组织发生氧化胁迫,试验为进一步从抗氧化系统的角度研究硒暴露对鱼类等水生生物的毒性作用机制奠定了基础。
