Protection and induction of chromosomal damage by vitamin C in human lymphocyte cultures

Abstract excerpt

Some chemotherapeutic approaches have proposed the use of antioxidants such as vitamin C (VC) to minimize the cytotoxicity and damage induced in normal tissue by antitumor agents that produce free radicals. Nevertheless, VC can also be cytotoxic, genotoxic, and harmful when combined with antitumor agents in human cells in vitro. The present study was undertaken to investigate the effects of VC (100, 200, 500, and...
