Abstract |
OBJECTIVE This controlled trial investigated the effect of supplementation with vitamins C and E on the lipid peroxide, antioxidant ability, and antioxidant vitamin levels in full term maternal and umbilical venous plasma. METHODS: Forty pregnant women were randomized in this study. They were nulliparous or multiparous women with history of preeclampsia or preterm premature rupture of membranes (PPROM). Twenty women were given vitamin C (1,000 mg/day) and vitamin E (400 IU/day) from 15~20 gestational weeks to delivery. The others were not given, as a control group. Maternal venous blood was obtained before vitamin supplementation and just before delivery. Umbilical venous blood was obtained after delivery. Lipid peroxide level and oxygen-radical absorbance capacity (ORAC) were measured by thiobarbituric acid reaction and Cao's method, respectively. Ascorbic acid, uric acid, beta-carotene, retinol, alpha-tocopherol, and gamma-tocopherol were measured by high performance liquid chromatography. Results: Supplementation with vitamins C and E was associated with decrease in lipid peroxide levels and increase in ORAC values and alpha-tocopherol levels in maternal venous plasma. And it was also associated with decrease in lipid peroxide levels and increase in ORAC values and alpha-tocopherol levels in umbilical venous plasma. CONCLUSION: Supplementation with vitamins C and E may be beneficial in the prevention of oxidant-antioxidant imbalance origin diseases such as preeclampsia, PPROM. And it also may affect antioxidant ability of the fetus. |
