The genotoxic and antigenotoxic effects of tannic acid in human lymphocytes.

The genotoxicity of tannic acid (TA, tannin) were investigated using chromosome aberration (CA), sister chromatid exchange (SCE), and micronucleus (MN) test systems in human peripheral lymphocytes. Also, the antigenotoxicity of TA against known mutagen EMS was also examined. The lymphocytes were treated with 1.
