Fig. 4. Radioprotective effect of delphinidin against proton beam exposure.

Fig. 4

(A) ROS scavenger effects of delphinidin in proton-exposed HEL 299 cells. ROS scavenger effect of delphinidin was measured by the 2′-7′-dicholordihydrofluorescein diacetate (DCF-DA) assay. Results are expressed as the intensity of DCF-DA fluorescence. (B) Effects of delphinidin on superoxide dismutase (SOD) activity in proton-exposed HEL 299 cells. (C) Effects of delphinidin on catalase (CAT) activity in proton-exposed HEL 299 cells. The measured data are expressed as mean ± SD. Values with different letters are significantly different from each other at P < 0.05 by Duncan's multiple range tests. CG, Control group; EG, exposed group without pretreatment; EG-LDp, exposed group with low concentration of delphinidin; EG-HDp, exposed group with high concentration of delphinidin.
