Supplementation of COS (0.5–5%) significantly increased the SOD activity in the liver of DF diabetic rats (p < 0.05 vs. HF or DF group; Figure 8Ba), but only COS 1% supplementation significantly increased the GPx activity (p < 0.05 vs. HF or DF group; Figure 8Bb). The gene discussed is SOD1; the disease is hydrops fetalis.
