Kaplan-Meier morbidity curves as a function of diet for rats given 11 Gy single-dose PBI with one-hind limb shielded, where morbidity is defined as a BUN of 120 mg/dl. Panel A, Study 1: animals continuously fed a standard natural-ingredient rodent diet, Teklad 8904 (n=12, black); animals switched at 2 weeks prior to irradiation to a casein-based AIN-76A diet (n=8, green); animals switched at 1 week after irradiation to the same AIN-76A diet (n=14, red). Panel B, Study 2: animals continuously fed Teklad 8904 (n=6, black); animals switched at 1 week after irradiation to the casein-based AIN-76A diet (n=5, red); animals switched at 1 week after irradiation to a further modified AIN-76A diet in which the protein was switched from casein to soy (n=8, blue). In both studies, once the diet switch was made, animals stayed on the AIN-76A diet for until 18 weeks after irradiation when the diet was changed back to Teklad 8904.
