    【Abstract】 Objective To investigate the total and free magnesium of plasma in pregnancy and in case of preeclampsia.Methods The total magnesium and free magnesirm of plasma were determined by 7600 Auto Analyzer and NOVA Blood Gas Analyzer respectively. Results There are no significantly differences in the total and free magnesium levels between in the control women and in the early or mid-term pregnancies. The levels of total and free magnesium decreased significantly in late term pregnancy and in preeclampsia, and both of the total and free magnesium levels increased markedly after magnesium sulfate was given to the cases of preeclampsia. Conclusion It is useful to detect the total and free magnesium for the trement of preeclampsia. ......
