Effect of CrVI on the activities of oxidative stress markers (LPO and H2O2) and AOXs (Gpx and Sod) in the placental extracts. Pregnant mothers (n = 5) received drinking water with or without CrVI (50 ppm) from 9.5 to 14.5 dpc. Placentas were separated on 18.5 dpc and extracts prepared as given in materials and methods. Histograms of LPO (A), H2O2 (B), Gpx (C), and Sod (D) are shown. dpc, days postcoitum. Each value represents mean ± SEM of 5 placentas. *Control versus CrVI, P < .05.
