Abstract
ESCALANTE-GOMEZ, Carlos; QUESADA-MORA, Silvia and ZELEDON-SANCHEZ, Fernando. Oxidative Profile of the Menopausal Woman: Estrogens´ Rol in the Prevention and Treatment of Diseases. Acta méd. costarric [online]. 2009, vol.51, n.4, pp.206-212. ISSN 0001-6002.
The cell carefully regulates the balance between the production of radical oxygen species and antioxidant enzymes levels. Antioxidant enzymes are critical for aerobic cells to maintain within balance free radical production. During the climacteric transition, the body and its metabolism suffer many changes and the mechanisms that regulate oxidative balance are not the exception. Estrogens, per se, are antioxidants, and this has promoted several studies to investigate the potential role of estrogens in disease prevention. Within the last few years, a great deal of studies have shown the relationship between oxidative stress and diseases such as therosclerosis and cardiovascular disease, cancer and Alzheimers disease. It appears that estrogens do modify the oxidative / anti-oxidative equilibrium in vivo, but more investigation is needed to further specify their role in disease prevention during the climacteric phase.
