MPO and gestational diabetes: As shown in Figure 6, the levels of NO (10.61 ± 1.61 μM) and MDA (27.01 ± 1.6 μM) as well as the activity of MPO (5.6 ± 0.51 mU/mL) were significantly increased by 0.92-fold (p < 0.0001), 0.9-fold (p < 0.0001), 1.3-fold (p < 0.0001), and – 0.49-fold (p < 0.0001), respectively, in the GDM group compared with those (5.52 ± 0.9 μM, 14.2 ± 2 μM, and 2.44 ± 0.26 mU/mL, respectively) in the NPC group.
