Quantitation of histological observations of normal lung tissue following treatment with radiation and soy

Histological findings of normal lung tissue surrounding the tumor nodules, from the experiment presented in Figures 3 and 4 were quantified and the extent of inflammatory infiltrates, hemorrhages and fibrosis were scaled from weak (±), moderate (+), strong (++) to heavy (+++). The fibrotic score was obtained from analysis of lung sections stained with Masson-Trichome as shown in Figure 4. Lung tissue sections of the left and right lung were separately analyzed because only the left lung was irradiated.
