title: Prostaglandin E2, trace elements and levels of oxidative processes in spontaneous miscarriages.
abstract: We investigated the significance of prostaglandin (PG)E2, trace elements level, pro-oxidative and antioxidative parameters changes in spontaneous miscarriages.
  
  
  
  In the 125 first trimester pregnancies, 35 with complete spontaneous abortion (group S), 40 with missed abortion (M) and 50 healthy (H), PGE2 plasma concentrations were analysed by commercial ELISA kits, plasma trace elements colorimetrically, lipid peroxidation and the antioxidative enzyme activities in hemolysate by commercial sets. Student's t-test and ANOVA were applied.
  
  
  
  Average PGE2 plasma concentration in the group H was higher than in S and M (p < 0.05). The higher average plasma Cu concentration, glutathione peroxidase and catalase contents were in the group H than in groups S and M (p < 0.01). Significantly lower value of lipid peroxidation was in the group H than in the groups S and M (p < 0.01). The lowest superoxide dismutase (SOD) content was in the group H and the highest in group S (p < 0.01).
  
  
  
  In patients with abortions significantly lower levels of plasma PGE2, plasma Cu and anti-oxidative enzymes, except SOD, and significantly higher level of lipid peroxidation products than in healthy pregnancies may be important for miscarriage etiology and prevention.
