Malondialdehyde and antioxidant enzymes in second and third trimesters of pre-eclamptic Nigerian women

To determine changes in malondialdehyde (product of lipid peroxidation) and antioxidant enzymes (Superoxide Dismutase, Glutathione Per-oxidase) levels in pre-eclamptic Nigerian women A Total of 100 subjects each for pre-eclamptic,apparently normal and non pregnant women were recruited into the study.Venous blood samples were taken from the participants during second and third trimesters of pregnancy and at the point of contact for non pregnant women. Malondialdehyde, glutathione peroxidase and superoxide dismutase were measured accordingly from plasma and haemolysate prepared from whole blood.Variables were analysed using SPSS version 16, taking level of significance to be 0.05 RESULTS: Plasma malondialdehyde in the third trimester (3.13±0.61umol/l) of pre-eclamptic subjects was higher than in the second trimester (3.00±1.21umol/l).Plasma malondialdehyde in the third trimester of normal pregnancy (2.03±0.71umol/l) was also found to be significantly higher than in the second trimester (1.65±0.62umol/ l)(p
