CRUZ MANZANO, Elio et al. Evidences of the maternal redox state regulation among the 30 and the 36 weeks of pregnancy. Rev Cubana Obstet Ginecol [online]. 2010, vol.36, n.4. ISSN 0138-600X.

Pregnancy is a physiological status characterized by a strictly controlled increase of oxidative processes. The risk of this oxidative process may to depend on the mother antioxidant status, which to potentially protect the mother-fetus unit increasing the intrauterine growth and the neonate weight. OBJECTIVE: To show evidences of mother redox satus regulation among the 30 and the 36 weeks of physiological pregnancy. METHODS: A cross-sectional, analytical and observational study was conducted including 36 healthy pregnants wit a single-fetus, and similar weight and gestational age between 30 and 36 weeks. As antioxidant defense indicators were determined the potential serum-ferric reduction agent, the extracellular superoxide dismutase and malondialdehyde concentration. It was also determined the hemoglobin ,serum ferric and glycemia, as well as the body mass index (BMI) and its variation. Based on the methodology of routes analysis there were structural equations forms with study variable. RESULTS: The ferric redactor potential and the serum concentration of malondialdehye were positively correlated to serum activity of superoxide dismutase and to the reduced glutathione concentration were the malondialdehyde contributes more than the ferric redactor potential and its variation. Glycemia also was directly related to lipid peroxidation and to antioxidant status indicators. CONCLUSIONS: Pregnants included in present study had a suitable redox balance, and the malondialdehyde or some other product of lipid peroxidation may be related to stimulation of protective responses for its maintenance.
