Effects of EGb on cell viability. Cell viability after treatments with different concentration of EGb (A). Cell viability after treatments with 25 mg/mL of EGb, 75 mM of H₂O₂ or a combination of them (B). Cells treated with DMSO were used as control. Fluorescent microscopic image of DAPI/PI stained cells; DAPI: blue; PI: red (C). Histogram reports quantification of fluorescence of DAPI and PI (D). The bars represent ± the average ± SD of independent experiments (n = 3). Statistically significant difference compared to control cells: ** p ≤ 0.01, *** p ≤ 0.005.
