Antigenotoxic and Apoptotic Activity of Green Tea Polyphenol Extracts on Hexavalent Chromium-Induced DNA Damage in Peripheral Blood of CD-1 Mice: Analysis with Differential Acridine Orange/Ethidium Bromide Staining

Figure 3

Effects of polyphenol extracts of green tea on the MN-PCEs frequency (% reduction) in mice peripheral blood at different times: (a) 24 h, (b) 48 h, and (c) 72 h after treatment with CrO₃. Data represent MN-PCEs frequency obtained at 24, 48, and 72 h minus the MN-PCEs frequency at 0 h (NIF). ^a𝑃<0.05  versus control group; ^b𝑃<0.05  versus polyphenol extracts of green tea group; ^c𝑃<0.05  versus CrO₃-polyphenol extracts of green tea group. 𝑛=5 (2000 cells for mouse).
