Cell lysates were analyzed by a colorimetric assay of Ac-DEVD-pNA. Each experiment was repeated 3 times. Data presented as mean ± standard deviation (n = 3). Caspase activities were given as arbitrary units (AU) per milligram of protein. Untreated H446 cells were used as a negative control group. *P<0.05 as compared to the corresponding control group. ^# P<0.05 as compared to corresponding EVO treated group at 24 h. P<0.05 as compared to corresponding EVO treated group at 48 h.
