The effects of EP and CS extracts on caspase 3 activity in human lung cancer cells. Cells were treated with 100 and 300 ng/mL of EP and CS extracts for 36 h and the activity of caspase 3 measured accordingly. a: represents the activity of caspase 3 following 100, 300 ng/mL of EP and 300 ng/mL of EP + 50 ng/mL of AM630 treatment. b: represents the activity of caspase 3 following 100, 300 ng/mL of CS and 300 ng/mL of CS + 50 ng/mL of AM630 treatment. Data represent Mean ± SD of three separate experiments. The statistical differences between treated and untreated groups were analyzed by ANOVA and are indicated by asterisks (* = P < 0.05, ** = P < 0.01)
