ABSTRACT

In the present study, we investigated the hepatoprotective effects of schisandrin B (Sch B) and green tea polyphenols (GrTP), two natural antioxidants, against Hg hepatotoxicity. Fifty-six rats were randomly divided into four groups of fourteen animals in each group: control group, Hg-treated group, Sch B pretreated group, and GrTP pretreated group. HgCl2 injection increased Hg accumulation, pathological and ultrastructural injury, lactate dehydrogenase (LDH) level, alanine transaminase (ALT) level, apoptosis, reactive oxygen species (ROS) level, glutathione (GSH) level, and malondialdehyde (MDA) level. HgCl2 injection decreased glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) activities. Sch B and GrTP protected against Hg-induced dysfunction and liver injury by enhancing the antioxidant defense system. Our results indicate that Sch B and GrTP exert antioxidative effects against Hg-induced hepatotoxicity in rats.
