Unalamation (pronounced: un-ala-mation).[1] describes homeostatic physiology where the so called 'inflammatory' lipid mediators maintain normal homeostatic physiological functions under the influence of anti-inflammatory lipid mediators. When there is injury, physical or microbial, acute inflammation is triggered by the biosynthesis of inflammatory lipid mediators such as prostaglandins and leukotrienes[2]. Levels of these inflammatory mediators descend to normal tissue concentrations as the acute inflammation is resolved. In certain tissues such as kidneys, heart, brain, intestines, and during physiological changes such as ovulation and parturition[3], these 'inflammatory' lipid mediators are present at high concentrations or increased during the physiological change[4]. Yet, there are no signs of inflammation. It is the simultaneous presence of anti-inflammatory lipid mediators such as epoxy polyunsaturated fatty acids that regulate the inflammatory propensity of prostaglandins towards homeostasis and this is designated as unalamation[5][6]
