Pregnancy complications effect on the nickel content in maternal blood, placenta blood and umbilical cord blood during pregnancy

Figure 1 Distribution of birth weight and birth length. A: Distribution of birth weight and birth length in control group and disease group; B: Birth weight and birth length were shown as mean ± SD. ^aP < 0.05. Control group: Healthy women who delivered at term without pregnancy complications; Combined disease group: The group with gestational diabetes (GDM) and hypertensive disorder complicating pregnancy (HDCP).

Figure 2 Distribution of nickel content in maternal-fetal system. A: Nickel (Ni) content in maternal blood, placenta blood and cord blood in control group and disease group; B: The Ni content in maternal-fetal system is shown as mean ± SD. ^aP < 0.05 vs Ni content in umbilical cord blood in control group; ^cP < 0.05 vs Ni content in maternal blood in same group. Control group: Healthy women who delivered at term without pregnancy complications; Combined disease group: the group with gestational diabetes (GDM) and hypertensive disorder complicating pregnancy (HDCP).
