Obstructive jaundice (OJ) can cause multiple pathophysiological consequences including intestinal barrier dysfunction. Omega-3 has been indicated to have a promising therapeutic effect on OJ. This study aimed to further investigate the functions of omega-3 on OJ-induced intestinal injury. A rat OJ model was established by bile duct ligation with or without omega-3 administration. ELISA was utilized for measuring serum levels of inflammatory cytokines. Hematoxylin-eosin staining and TUNEL staining were employed for detecting the morphological changes and cell apoptosis in rat intestine. Western blotting was utilized for evaluating expression of tight junction proteins in the intestinal tissues. Omgea-3 offset the reduction in body weight of OJ rats. Omega-3 alleviated inflammatory response, pathological damages and cell apoptosis in the intestine of OJ rats. Additionally, omega-3 enhanced levels of tight junction proteins in the intestinal tissues of OJ rats. Omega-3 ameliorates OJ-triggered impairment of intestinal barrier function in rats.
