Fig. 1. PTU, PCBs, and AP on the body weight change in ovariectomized rats. Note: A: OVX. Control; B: PTU + PCBs (LOAEL); C: PTU + AP (LOAEL); D: PCBs + AP (LOAEL); E: PTU + PCBs + AP (LOAEL); F: PTU + PCBs + AP (BMDL). Mean body weight and weight change were graphed. One-way ANOVA was used to test the significant differences (p < 0.05) of each weight parameter among different groups.
