WebDec 14, 2010 · Oxygen toxicity caused by ROS progresses in overlapping phases based on degree of severity and reversibility of injury. The phases are initiation, inflammation, proliferation, and fibrosis. Initially, there are increased ROS and depleted antioxidant levels, and the lung fails to clear itself of mucous. WebOxidative stress also contributes to tissue injury following irradiation and hyperoxia, as well as in diabetes. In hematological cancers, such as leukemia, the impact of oxidative stress can be bilateral. Reactive oxygen species can disrupt the function of immune cells, promoting immune evasion of leukemic cells.
