Abstract
In a concentration higher than 5·10−7 M thyroxine delayed the development of chemiluminescence and reduced the rate of rise of the slow flash. The antioxidative activity of thyroxine was only a little less than the activity of the classical antioxidant α-tocopherol. In lower concentrations (of the order of 1·10−8 M) thyroxine had a peroxidant action, which was most marked in the case of intact mitochondria incubated in phosphate medium in the presence of Mg2+ ions and was weaker in mitochondria treated with Ca2+ ions in hypotonic medium.
