Fig. 1. Andrographolide protected mice from radiation-induced lung injury.

Fig. 1

Mice were exposed to 18 Gy irradiation and then treated with the indicated doses of Andrographolide for 4 weeks after irradiation. a Representative images of mice at 8 weeks post-irradiation. b Kaplan–Meier survival analysis of mice in different groups, n = 12 per group. c Representative images of H&E staining of lung tissues from each group. Alveolar hemorrhage and the thickness of the alveolar walls were indicated by arrows. Scale bar, 50 μm. d Semi-quantitative histological analysis of lung tissues of five fields per mouse in every group. e Lung coefficient of mice in each group. The results are shown as the mean ± S.E.M., n = 6 mice per group. *P < 0.05 vs the IR group.
