Effect of Salvia miltiorrhiza solution, salvianic acid A and salvianolic acid B on TNF-α protein expression in KGN cells. Representative microscopic photographs were obtained in the (A) control group, (B) 200 µM H₂O₂ group, (C) Salvia miltiorrhiza solution (0.2, 1 and 5%) group, (D) salvianic acid A (3, 10 and 30 µM) group and (E) salvianolic acid B group (3, 10 and 30 µM). Magnification, x400. (F) Quantification of TNF-α release measured via ELISA. ^#P<0.05 vs. control group and ^*P<0.05 vs. H₂O₂ group. TNF-α, tumor necrosis factor-α.
