Effects of PGE₁ on cell viability of H₂O₂-induced HUVECs as evaluated by MTT analysis (A) and LDH release (B). Values are expressed as mean±SD. n=6. ^cP<0.01 vs control group; ^eP<0.05, ^fP<0.01 vs the H₂O₂-alone group; ⁱP<0.01 vs the H₂O₂+0.25 μmol/L PGE₁ group; ^lP<0.01 vs the H₂O₂+0.50 μmol/L PGE₁ group; ^oP<0.01 vs the H₂O₂+1.00 μmol/L PGE₁ group.
