Three groups of subjects have been divided (25/group): healthy normotensive non-pregnant women (Group A), normal normotensive pregnant women (Group B), and women with preeclampsia (Group C).The levels of serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin , creatinine , blood urea nitrogen, triglyceride , total cholesterol and glucose have been estimated in all subjects. All measured parameters were determined by spectrophotometric analysis. The results showed a significant(P<0.05) increase in serum ALT, AST, blood urea nitrogen, triglyceride and total cholesterol levels in group B as compared to group A. However creatinine, total bilirubin and glucose levels did not show any statistical significant alterations. The women in group C showed to be associated with a significant (P<0.05) rise in all measured parameters except total bilirubin as compared to women in group A. The preeclamptic women (group C) showed significant (P< 0.05) increase in serum alanine aminotransferase , blood urea nitrogen , triglyceride , total cholesterol and glucose levels as compared to women in group B. While serum aspartate aminotransferase, total bilirubin and creatinine levels did not show any statistical significant alteration.
