    Abstract:
    Fish Lateolabrax japonicus were exposed to 0.1 and 1mg/L of anion surfactant sodium dodecylbenzene sulfonate (SDBS) and to 2 and 20 microg/L of benzo[a]pyrene (B[a]P) for 6, 12, and 18 days, with control and solvent control groups. Liver antioxidant enzymes, including superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), reduced glutathione (GSH), and glutathione S-transferase (GST), were determined; brain acetylcholinesterase (AChE) and liver inducible nitric oxide synthase (iNOS) activities were also measured. The results indicated that (1) L. japonicus avoided oxidative damage through antioxidant systems; (2) SOD, GPx, and GSH were induced, and GST was inhibited and then induced by B[a]P exposure; and (3) CAT, GPx, and AChE were induced while iNOS was inhibited, and GST was induced and then inhibited by SDBS stress in experimental period.
