Although differences in SOD activity did not reach statistical significance among the groups, the HF+RS and HF+FG groups similarly modulated the corresponding antioxidant enzyme ratios promoting CAT and GPx over SOD, especially evident after receiving FG that promoted higher CAT activity (CAT/SOD ratio, p value = 0.085 for HF+RS vs. HF groups and p value < 0.05 for HF+FG vs. HF groups). The gene discussed is CAT; the disease is hydrops fetalis.
