(a) Kaplan-Meier survival rate curve of 4 groups (n = 10) administrated with PEG400 (vehicle), α-TS (400 mg/kg), γ-TOS (400 mg/kg), δ-TOS (400 mg/kg) 24 h before and 1 h after the 9.5 Gy TBI. (b) Kaplan-Meier survival rate curve of 4 groups (n = 10) administrated with PEG400 (vehicle), δ-TOS (100 mg/kg), δ-TOS (200 mg/kg), δ-TOS (400 mg/kg) 24 h before and 1 h after the 9.5 Gy TBI. P value was calculated by log-rank test.
