Figure 2 reveals that serum AST activities were visibly accelerated in the HF group (P < 0.05); however, AST activity was decreased in the FG group which is treated with genistein (500 mg/kg) in the HF diet compared with the HF group. Furthermore, serum LZM activity was significantly declined in HF or HC groups (P < 0.05); however, they were upregulated in FG or CG groups. This evidence concerns the gene LYZ and hydrops fetalis.
