title: Antioxidant activity of ethanolic extract of Tinospora cordifolia on N-nitrosodiethylamine (diethylnitrosamine) induced liver cancer in male Wister albino rats.
abstract: BACKGROUND
  Cancer is a disease that evokes wide spread fear among people and is one of the leading causes of deaths in the world. Diethylnitrosamine (DEN) is a known carcinogen in rodent liver. DENs reported to undergo metabolic activation by cytochrome P450 enzymes to form reactive electrophiles that cause oxidative stress leading to cytotoxicity, mutagenicity and carcinogenicity.
  
  
  OBJECTIVE
  The present study was carried out to evaluate the antioxidant activity of ethanolic extract of Tinospora cordifolia (EETC) in N-nitrosodiethylamine (DEN) induced liver cancer in male Wister albino rats.
  
  
  METHODS
  The antioxidant activity was assessed by the levels of lipid peroxidation (LPO), enzymic and nonenzymic antioxidants.
  
  
  RESULTS
  A significant levels of LPO was increased as the enzymic and nonenzymic antioxidants values were decreased in liver cancer bearing animals.
  
  
  CONCLUSIONS
  The administration of EETC to cancer bearing animals reverted the LPO levels, enzymic and nonenzymic antioxidants to near normal.
