Effect of nitrones on the activities of phase II enzymes and intracellular GSH in BAEC. BAEC were incubated with different concentrations of nitrone (0–50 µM) for 24 h, and phase II enzyme activities were spectrophotometrically assessed. Following the protocol described in “materials and methods” section, activities from the cell extracts were determined for (A) HO-1, (B) NQO1, (C) GR, (D) GPx and (E) GSH, respectively. Results are represented as mean ± SEM, *p < 0.05 vs. control (nitrone-untreated cells), where n = 3.
