摘要： Condensed tannins (CT) were demonstrated to mitigate oxidative stress and maintain intestinal health of fish, but little information is available to clarify the underlying regulation mechanisms. This study was conducted to evaluate the effects of CT supplementation on growth, antioxidant capacity and intestinal barrier function of Lateolabrax maculatus via in vivo oxidized fish oil-induced and in vitro hydrogen peroxide-induced stress models. Results indicated that dietary inclusion of 0.1% CT mitigated oxidative injure and intestinal damage caused by oxidized fish oil as reflected by the recovery of growth performance, serum antioxidant capacity, intestinal permeability and tight junction proteins gene expression. Supplementation of 800 mu mol/L of CT in the L. maculatus intestinal epithelial cells damage induced by hydrogen peroxide as in vitro model increased (P < 0.05) cell viability, antioxidant enzyme activities and nuclear factor erythroid 2-related factor 2 gene expression, but decreased (P < 0.05) reactive oxygen and malondialdehyde concentrations. In conclusion, CT is effective in protecting against oxidized fish oil-induced and hydrogen peroxide-induced oxidative injure and intestinal damage of L. maculatus.
