Figure 5.

HUVECs were plated in 6-well plates (1.5 × 10⁵ cells/well) and treated with 10 μg/mL of FP for 24 h followed by treatment with H₂O₂ (300 µM) for 24 h. (A) CAT, (B) GR, (C) Gpx, and (D) SOD activities were assayed by the methods described in the Methods. Enzyme activity is expressed as units per milligram protein. Results are expressed as mean ± SD of at least three experiments. * p < 0.05 significantly different from the control (ctrl). ° p < 0.05, significantly different from H₂O₂-treated HUVECs. Ctrl (control, untreated cells); H₂O₂ (cells treated with hydrogen peroxide); FP (cells pretreated with fermented Pushgay).
