摘要： Tributyltin (TBT), as antifouling paints, is widely present in aquatic environment, but little is known regarding the toxicity of TBT on fish brain. In this study, the effects of exposure to TBT on the antioxidant defense system, Na+-K+-ATPase activity, neurological enzymes activity and Hsp 70 protein level in brain of juvenile common carp (Cyprinus carpio) were studied. Fish were exposed to sublethal concentrations of TBT (5, 10 and 20 g/L) for 7 days. Based on the results, with increasing concentrations of TBT, oxidative stress was apparent as reflected by the significant higher levels of oxidative indices, as well as the significant inhibition of all antioxidant enzymes activities. Besides, the activities of Acetylcholinesterase (AChE), Monoamine oxidases (MAO) and Na+-K+-ATPase were significantly inhibited after exposure to TBT with higher concentrations. In addition, the levels of Hsp 70 protein were evaluated under TBT stress with dose-depended manner. These results suggest that selected physiological responses in fish brain could be used as potential biomarkers for monitoring residual organotin compounds present in aquatic environment.
