Preeclampsia is a disease in pregnancy and characterized by hypertension and proteinuria. Preeclampsia and eclampsia are the most causes of maternal and fetal mortality and morbidity in Indonesia. Placental and systemic oxidative stress caused endothelial cell dysfunction and injury. Placental oxidative stress also linked to fetal growth restriction. HSP70 is essential for cellular recovery, survival and maintenance of homeostasis. The purpose of this study was to compare the MDA, a marker for oxidative stress and HSP70 production in placental of severe preeclampsia, mild preeclampsia and normotensive pregnant women. Placenta were collected after delivery from normotensive pregnancies (N=10), severe preeclampsia (N=10) and mild preeclampsia (N=10). Placenta was cultured in RPMI and 20% FBS, and supernatant were collected in day 3. MDA was measured using spectrophotometer and absorbance read in 530nm. HSP70 was measured using enzyme-linked immunosorbent assay. The mean MDA concentration did not differ significantly between patients with severe preeclampsia (7.13+5.36 nmol/ml) and mild preeclampsia (4.82+2.47 nmol/ml) when compared with normotensive pregnancies (4.57+2.4 nmol/ml). The mean HSP70 concentration in mild preeclampsia is highest (10.15+12.39 nmo/ml) when compared with severe preeclampsia (3.78 +3.07 nmol/ml) and normotensive pregnant women (3.76+4.65nmol/ml), but the difference was not significant. Although the difference was not significant, is indicates homeostasis response in mild preclampsia women is relative good. This response was abated in severe preeclampstic women. Although MDA and HSP70 concentration did not differ significantly between groups, however the high HSP70 concentration is indicates homeostasis response relatively good in mild preeclamptic women.
