title: [Total and ionized magnesium concentration in the blood plasma and erythrocytic magnesium concentration of women in the third trimester of pregnancy with imminent preterm labor].
abstract: OBJECTIVE
  There are some data concerning magnesium concentration influence on the risk of preterm labor. The estimation of magnesium concentration changes may be useful in prevention of preterm labor.
  
  
  METHODS
  Therefore the aim of our study was to find out the correlation between magnesium concentration and the risk of preterm labor.
  
  
  METHODS
  Total magnesium concentration and ionized magnesium concentration in blood plasma and erythrocytic magnesium concentration ware examined in the three groups of: 23 women in the third trimester of pregnancy with imminent preterm labor under tocolytic therapy; 20 women in the third trimester of physiologic pregnancy and 19 non-pregnant healthy women in the reproductive age.
  
  
  RESULTS
  We discovered statistically confirmed differences (p < 0,05 ) in ionized magnesium concentration as well between the group of women in physiologic pregnancy and non-pregnant women and between the group of pregnant women with imminent preterm labor and non-pregnant women.
  
  
  CONCLUSIONS
  Although there were no statistically confirmed differences in total magnesium concentration and erythrocytic magnesium concentration between the three groups of examined women, there were statistically confirmed differences in ionized magnesium concentration between the pregnant and non-pregnant women. Our results suggest that ionized magnesium concentration is better indicator of magnesium balance in human's body than total magnesium concentration.
