Figure 1. Cardiac inflammatory cell numbers at 6 months after irradiation.

Figure 1

Radiation caused an increase in mast cell numbers and CD68 positive cells, as shown by representative micrographs (A) and total cell counts (B). TSB reduced the effects of radiation on cardiac mast cell number. PTX enhanced the effects of radiation on the number of CD68 positive cells. Average ± SEM, n=8-9. *Significant difference with sham-irradiation (p<0.05), † Significant difference with 21 Gy (p<0.05). Scale bar: 100 μm.
