VENEREO GUTIERREZ, Justo R.. Daño oxidativo, radicales libres y antioxidantes. Rev Cub Med Mil [online]. 2002, vol.31, n.2, pp.126-133. ISSN 0138-6557.
A literature review was made on the topic of free oxygen radicals, reactive oxygen species and oxidative stress to bring medical science specialists closer to the interesting and ever increasingly important world of free radicals, a topic of interest at present not only for biochemists, physiologists and other specialists in basic medical sciences but for other experts as well. This paper provides a general view of the main aspects of this topic, concepts, classifications and characteristics of free radicals, and of the various systems of antioxidant defense. Also, it briefly explains the mechanisms by which these chemical species damage the body, and finally makes recommendations from the hygiene-dietary viewpoint in order to keep an adequate prooxidant-antioxidant balance.
