Figure 3. Histology of lung tissue from A549 lung tumor-bearing mice treated with radiation and soy.

Figure 3

A. Lung tissue from control mice showing normal lung alveoli. B, C. Lung tissue from left and right lung from mice treated with soy showing no changes in the morphology of lung alveoli compared to control mice. D, E. Irradiated left lung showing heavy infiltration of inflammatory cells [IF arrows] consisting mostly of lymphocytes and a few neutrophils. Fibrous tissue [F arrows] is observed in the midst of inflammatory infiltrates [IF arrows]. In panel E areas of extensive hemorrhages [H arrows] with inflammatory infiltrates are observed in irradiated lung tissue. F. Non-irradiated right lung from radiation (left lung) treated mice showing normal lung tissue morphology. G, H. Irradiated left lung from mice treated with left lung irradiation and systemic soy. The morphology of lung tissue resembles normal alveoli as seen in control mice. I. Right lung non-irradiated from mice treated with left lung irradiation and systemic soy showing normal morphology of lung tissue. All magnifications 40X.
