FGF1 and hydrops fetalis: Moreover, MDA and SOD were also detected (Figures 3B–C); MDA was increased obviously (p < 0.05) and SOD was decreased in the DOX-HF group apparently compared with the control group (p < 0.05); aFGF-NP + UTMD group (p < 0.05) and aFGF + UTMD group (p < 0.05) significantly lowered MDA levels and increased SOD levels compared with the DOX-HF group.
