Özet

The aim of the present study was to measure plasma uric acid (UA) levels and superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and xanthine oxidase (XO) activities and to evaluate the relationship between these parameters and the severity of pre-eclampsia. Twenty-five pre-eclamptic, 15 healthy pregnant and 15 non-pregnant women were enrolled in this study. Increased mean plasma XO activity was found to be higher in both pre-eclampsia groups than in the healthy pregnant group. Plasma UA levels were the highest in the severe pre-eclampsia group among the study groups. SOD and GSH-Px activities were significantly lower in both pre-eclampsia groups than in the healthy pregnant group (p < 0.005 andp < 0.001, respectively). Increased XO and decreased SOD and GSH-Px activities may contribute to the pathophysiological mechanisms of pre-eclampsia and increased UA may serve a protective role responding to superoxide radicals arising from increased XO activity or other sources in pre-eclampsia.
