M867 Inhibits Radiation Induced Apoptosis and Smad2/3 Mediated Inflammatory Response in Lung Parenchyma. A: Lung tissue slides were subjected to TUNEL assay. Shown are representative photographs of histology slides. B: Bar graphs of mean (10 random fields) percentages of cells that stained positive with SEM. P-values are indicated. C: One mouse from each treatment group was sacrificed. Mice lungs were removed and immunostained for p-Smad2/3. Shown are representative photographs of histology slides, magnification is x 40. D: Bar graph of mean (10 random fields) percentages of cells that stained positive for p-Smad2/3 with SEM. P-values are indicated.
