CORRIA OSORIO, Jesús  and  CRUZ MANZANO, Elio. Balance between reactive species and antioxidant systems in a normal pregnancy. Rev Cubana Obstet Ginecol [online]. 2009, vol.35, n.2, pp. 0-0. ISSN 1561-3062.

Pregnancy is a state characterizing by an increase, strictly regulated of oxidative processes in mother and in fetus, determined by an increase of dioxygen consumption, and by use of some reactive species in some cellular processes significant for mother-fetus development. Short- and long-term lack of anti-oxidant/pro-oxidant balance, favouring these later, provoke oxidative stress and damage to bio-molecules, loss of functions and apoptosis, affecting the normal course of pregnancy. Thus, it is important to know regulation of redox state in this period. In present review are showed some of main studies and results discussed evidencing role of Reactive Species and Anti-oxidant systems in normal pregnancy.

Keywords : Oxidative stress; pregnancy; fetal weight; low-birth weight; eactive species; anti-oxidative systems; redox state.
