PLAG increased survival rates and mitigated body weight loss in mice receiving an LD70/30 dose of gamma rays. Mice (n = 40 per group, 20 males and 20 females) received the LD70/30 dose (6.11 Gy) of gamma rays, and were administered 50 or 250 mg/kg of PLAG once a day starting the day after irradiation and continuing until the final day of observation. Panel A: Survival was monitored for 30 days. P = 0.0041, 6.11 Gy + PLAG 50 mg/kg vs. 6.11 Gy; P < 0.0001, 6.11 Gy + PLAG 250 mg/kg vs. 6.11 Gy (log-rank test). Panel B: Body weights were measured daily for 30 days. Data are presented as mean. #6.11 Gy vs. 6.11 Gy + PLAG 50 mg/kg; *6.11 Gy vs. 6.11 Gy + PLAG 250 mg/kg. #/*P < 0.05, ##/**P < 0.01, ###/***P < 0.005.
