We found that AA treatment significantly alleviated radiation-induced lung histopathological damage (Fig 11B), reduced inflammatory cytokines IL-1β, IL-4, IL-6, IFN-γ in BALF (Fig 11C-11F), mitigated oxidative stress (Fig 11G and 11H), and improved pulmonary edema and overall health status (Fig 11I and 11J). The gene discussed is IL6; the disease is edema.
