ABSTRACT
<p><b>OBJECTIVE</b>The aim of our study was to assess the complications of hepatic fibrosis associated with bile duct ligation and the potential curative role of sepia ink extract in hepatic damage induced by bile duct ligation.</p><p><b>METHODS</b>Rattus norvegicus rats were divided into 3 groups: Sham-operated group, model rats that underwent common bile duct ligation (BDL), and BDL rats treated orally with sepia ink extract (200 mg/kg body weight) for 7, 14, and 28 d after BDL.</p><p><b>RESULTS</b>There was a significant reduction in hepatic enzymes, ALP, GGT, bilirubin levels, and oxidative stress in the BDL group after treatment with sepia ink extract. Collagen deposition reduced after sepia ink extract treatment as compared to BDL groups, suggesting that the liver was repaired. Histopathological examination of liver treated with sepia ink extract showed moderate degeneration in the hepatic architecture and mild degeneration in hepatocytes as compared to BDL groups.</p><p><b>CONCLUSION</b>Sepia ink extract provides a curative effect and an antioxidant capacity on BDL rats and could ameliorate the complications of liver cholestasis.</p>

OBJECTIVE@#To evaluate the curative effect of the 132 KD protein isolated from the seeds of Peganum harmala (P. harmala) L. against carbon tetrachloride (CCl(4)) induced oxidative stress in rats.@*METHODS@#Animals were post treated intraperitoneally with 132 KD isolated protein at doses of 4 and 8 mg/kg body weight and bovine serum albumin (BSA) (8 mg/kg body weight) as well as vitamin C (250 mg/kg body weight p.o.) for 7 d after they challenged with CCl(4) orally (1 mL/kg body weight) in olive oil (50%) for 2 d.@*RESULTS@#The purified protein from seeds of P. harmala plant showed in vitro antioxidant activity with DPPH assay. Administration of CCl(4) induced induction in serum aminotransferases (AST, ALT), alkaline phosphatase (ALP), lipid profile parameters and liver malondialdehyde (MDA) and decrease in serum total protein, liver superoxide dismutase (SOD), catalase (CAT), and reduced glutathione (GSH) levels. 132 KD protein treatment of rats post CCl4 intoxication successfully alleviated the toxic effects of CCl(4).@*CONCLUSIONS@#The isolated protein possessed strong antioxidant activity comparable to that of BSA (negative control) and vitamin C (positive control).
