Figure 1

Body weights (mean ± SEM) of proton irradiated and control rats. There were no differences in weight at the time of irradiation. Regardless of dose, irradiated rats had decreased body weights (p < 0.0001). The 11 Gy rats had decreased weights at 5 weeks, no difference at 6 weeks, and decreased weights the rest of the testing period compared with controls.. The 14 Gy and 17 Gy rats had decreased weights at week 1 until the end of testing with the exception of week 6 in the 14 Gy rats when there was no difference compared with controls. n = 10/group for sham controls, 11 Gy, and 17 Gy and 8–10 for 14 Gy.
