The lipid hyperoxide (LH) levels according to the cumulative iron dose (A) and radiation dose (B). (A) LH (µM) was highest in the mice that received 200 mg of iron at post-HSCT day 7 (P=0.01). All mice (N=6) treated with allogeneic HSCT received 1,100 cGy. (B) LH was highest in the recipients of 1,100 cGy (P<0.01) of radiation. All mice (N=6) treated with allogeneic HSCT had cumulative iron levels of 100 mg. Beeswarm boxplots show the median values and the quartiles, and single measurements are shown as open circles. The middle bar in the box denotes mean value. a)P<0.01 in t-test, b)P<0.01 in ANOVA.
