Effects of PGE₁ on the production of intracellular ROS was determined by measuring the intensity of DCFH fluorescence. (A) Control group; (B) H₂O₂-alone group; (C) H₂O₂+0.25 μmol/L PGE₁ group; (D) H₂O₂+0.50 μmol/L PGE₁ group; (E) H₂O₂+1.00 μmol/L PGE₁ group; (F) H₂O₂+1.5 mmol/L Vc group; (G) Effects of PGE₁ on the production of intracellular ROS. The values are expressed as percentages of the fluorescence intensity. Mean±SD. n=4. ^cP<0.01 vs control group; ^fP<0.01 vs the H₂O₂-alone group.
