In the DJOS-operated rats, the erythrocytes CAT activity differed significantly among studied dietary groups, i.e., HF/HF and CD/HF, HF/HF and HF/CD, and HF/HF and CD/CD, with the lowest activity measured for the CD/HF diet group and the highest measured for the HF/HF group (Figure 2B and Table 2). Here, CAT is linked to hydrops fetalis.
