In addition, compared with the control group, the levels of superoxide dismutase (SOD) in the livers of the HF + STZ group were significantly downregulated (p < 0.05), while the SOD levels in the livers of the HF + Cur + STZ group were significantly upregulated (p < 0.05) compared with those in the HF + STZ group. Here, SOD1 is linked to hydrops fetalis.
