Survival rates of mice. (a) Different dosages of GSPs were given by gavage about 1 h before radiation and maintained through drinking until 1 week after radiation. (b) Different effects of the three strategies of GSPs (400 mg/kg of the body weight) delivery including therapy (after radiation, survival 40%), prevention (before radiation, survival 50%), and the combination of therapy and prevention medication (after radiation and before radiation, survival 80%). Representative results from one of three independent experiments are shown. ; control, ; others, .
