Fig. (10) Effect of LCLE treatment on caspase-3 activity in U937, K562 and HL-60 cells. (A) histogram showing caspase-3 activity of untreated control and LCLE (50, 100 and 150 µg/ml) treated U937 cells, (B) histogram showing caspase-3 activity of untreated control and LCLE (50, 100 and 150 µg/ml) treated K562 cells and (C) histogram showing caspase-3 activity of untreated control and LCLE (50, 100 and 150 µg/ml) treated HL-60 cells. The SE value was < 0.001 in bars where no indication is shown for SE.
