(25) studied the protective effects of quercetin liposomes against radiation-induced pulmonary injury and found that irradiated C57BL/6 mice treated with quercetin liposomes had significantly increased SOD activity and decreased MDA content to protect against radiation-induced acute pneumonia and chronic pulmonary fibrosis by reducing oxidative damage compared with irradiated mice without treatment. The gene discussed is SOD1; the disease is pneumonia.
