Effects of radon inhalation on the microscopic morphology and IHI in the stomachs of mice with ethanol-induced gastric mucosal injury. (A) Histological appearances of the stomachs of mice in different groups: (a) control group; (b) 30% EtOH group; (c) 60% EtOH group; (d) Rn group; (e) Rn + 30% EtOH group; (f) and Rn + 60% EtOH group. Scale bar = 100 μm. All samples were stained with HE. The black arrow in (c) indicates typical injury area. (B) IHI scores. The number of mice for each experiment and significance are the same as those for Fig. 6.
