Aflatoxin-induced biochemical changes in liver of mice and its mitigation by black tea extract.
Aflatoxin belongs to the class of naturally occurring mycotoxins, food contaminants having potent carcinogenicity. We have evaluated the ameliorative role of black tea extract on aflatoxin-induced biochemical changes in the liver of albino male mice. Adult male mice were orally administered with 750 and 1500 pg of aflatoxin in 0.2 mL olive oil/kg b.w./day for 30 days. Oral administration of aflatoxin caused, as compared with controls, significant, dose-dependent reduction in DNA, RNA, protein and glycogen contents; however, cholesterol content and phsphorylase activity were significantly increased. Black tea is one of the most potent antioxidants containing numerous bioactive phytonurtients having therapeutic applications. Aflatoxin-induced changes in the liver of mice were significantly ameliorated on co-treatment of black tea extract (2% infusion in water).
