Figure 3.

The effect of beetroot on DNA damage caused by γ-ray irradiation in splenocytes, as measured with the alkaline comet assay. Splenocytes were isolated from mice of each experiment group 10 days after 7 Gy WBI. Data shown are representative of three independent experiments. (a) Naive group, (b) IR group, (c) IR + Beetroot group, (d) percentage of tail DNA, (e) olive tail movement, (f) tail length in each group, scored according to the Komet 5.5 program. Bars in (a)–(c) represent 30 μm. Each criteria was calculated in 100 cells per mouse. Data are expressed as mean ± SEM (*, †p < .05, **p < .01).
