Abstract
BACKGROUND Cisplatin is a potent anticancer agent widely employed in chemotherapy. However, cisplatin leads to toxicity on non-targeted healthy organs, including the liver. We investigated the hepatoprotective mechanism of arbutin (ARB), a glycosylated hydroquinone, against cisplatin-induced hepatotoxicity. METHODS Rats were orally administered with ARB (ARB1 = 50 mg/kg; ARB2 = 100 mg/kg) for 14 consecutive days against hepatotoxicity induced by a single dose of cisplatin (10 mg/kg) on day 15. Three days after the intraperitoneal cisplatin injection, serum and liver tissue were collected for subsequent analyses. RESULTS Cisplatin triggered marked increases in serum AST, ALT, and ALP activities, hepatic malondialdehyde (MDA) and reactive oxygen species (ROS) coupled with a considerable diminution in hepatic activities of superoxide dismutase (SOD), catalase (CAT) and the concentration of reduced glutathione (GSH). The gene expressions of interleukin-1β (IL-1β), tumor necrosis factor (TNF-α), and IL-6 were notably increased. The pre-administration of ARB1 and ARB2 reduced AST, ALT and ALP in serum and restored SOD, CAT, GSH, ROS, MDA and cytokine levels which was also evidenced by alleviated hepatic lesions. Further, cisplatin-induced prominent alterations in the gene expressions of nuclear factor erythroid 2-related factor 2 (Nrf2), heme oxygenase-1 (HO-1), iNOS, NF-κB, Bax, Bcl-2, caspase-3 and 8-OHdG in the liver. Interestingly, ARB protected the liver and mitigated the cisplatin-induced alterations in serum AST, ALT, ALP, and reduced hepatic redox markers, 8-OdG, inflammatory markers and gene expressions. CONCLUSION The findings demonstrate that ARB is a potential protective adjuvant against cisplatin-induced hepatotoxicity via inhibition of hepatic oxidative stress, inflammation, and apoptosis.

Abstract
This study was planned to assess the potential protective effects of taxifolin against thioacetamide-induced hepatic encephalopathy and subsequently to portray its behavioural results. The experimental model was induced with three doses of (200 mg/kg i.p.) thioacetamide and taxifolin (50 and 100 mg/kg, p.o.) was administered for fourteen days. Taxifolin effectively attenuated hepatic encephalopathy through decrease in AST, ALT, ALP and LDH concentrations and improvement of hyperammonemia, and increase in antioxidant capacity by decreasing MDA, ROS, and increasing CAT and GSH. In addition, the expressions of NF-κB, TNF-α, IL-1β, caspase-3 and Bax was down-regulated while IL-10 and Bcl-2 expressions were up-regulated with taxifolin treatment. The recovery was confirmed by downregulation of iNOS and 8-OHdG expressions in our immunohistochemical analysis. Taxifolin treatment reduced the disrupting role of thioacetamide as seen by corrected hyperammonemia as well as preservation of astrocyte and hepatocyte structure. Elevated plus maze and locomotor activity tests also proved that taxifolin might repeal the neurobehavioral disabilities. In conclusion, taxifolin has shown hepatoprotective and neuroprotective roles with antioxidant and anti-inflammatory effects, as well as suppressing the excessive release of ammonia, and it eventually reversed neurobehavioral impairments.
