The Immediate Defensive Reaction (by Vertebrate Tissue) to Infection or Injury Caused by Chemical or Physical Agents. the Process Is Characterized by Local Vasodilation Extravasation of Plasma Into Intercellular Spaces and Accumulation of White Blood Cells and Macrophages.
Any Process That Results in a Change in State or Activity of a Cell or an Organism (in Terms of Movement Secretion Enzyme Production Gene Expression Etc.) As a Result of Oxidative Stress a State Often Resulting From Exposure to High Levels of Reactive Oxygen Species E.g. Superoxide Anions Hydrogen Peroxide (h2o2) and Hydroxyl Radicals.
The Chemical Reactions and Pathways by Which Prostaglandins Are Formed From Arachidonic Acid and in Which Prostaglandin Endoperoxide Synthase (cyclooxygenase) Catalyzes the Committed Step in the Conversion of Arachidonic Acid to the Prostaglandin Endoperoxides Pgg2 and Pgh2.
