title: Hepatoprotective and antioxidant activity of N-Trisaccharide in different experimental rats.
abstract: OBJECTIVE
  To investigate the hepatoprotective, antioxidant and antihyperlipidemic effect of N-Trisaccharide isolated from Cucumis prophetarum (L.) on different experimental rats.
  
  
  METHODS
  N-Trisaccharide (25 and 50 mg/kg.b.w), silymarin (25 mg/kg) and glibenclamide (25 mg/kg) was orally administered once daily for 28 days and toxicity evaluation studies were carried out. Liver damage was assessed by determining DNA damage, serum enzyme activities and hepatic histopathology of carbon tetrachloride (CCl4) induced hepatic injury in rats. Enzymatic and non enzymatic antioxidant levels in liver and kidney were determined and biochemical parameters such as, serum lipid profile, renal function markers were estimated in type 2 diabetic rats.
  
  
  RESULTS
  DNA fragmentation analysis revealed the protective effect of N-Trisaccharide on liver DNA damage. Histopathological studies indicated that CCl4-induced liver injury was less severe in N-Trisaccharide (25 and 50mg/kg) treated group. Given at the above doses conferred significant protection against the hepatotoxic actions of CCl4 in rats, reducing serum markers like SGOT, SGPT, ALP, creatinine and urea levels back to near normal (p<0.05) compared to untreated rats. In diabetic rats, N-Trisaccharide treatment significantly reversed abnormal status of enzymatic and non-enzymatic antioxidants levels to near normal. Also, serum lipids such as TG, TC, LDL-C and VLDL-C levels were significantly (p<0.05) reduced compared to diabetic untreated rats.
  
  
  CONCLUSIONS
  Present study results confirm that N-Trisaccharide possesses significant antihyperlipidemic, antioxidant and hepatoprotective properties.
