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. Materials and Methods: The antioxidant activity was assessed by the levels of lipid peroxidation (LPO), enzymic and nonenzymic antioxidants. Result: 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
