The viability of the untreated control was taken as 100 %. The viability percentage was calculated for different concentrations of AEPa. No significant differences were found at 10–400 μg/ml of AEPa when compared with the control. b Propidium iodide (PI) exclusion test at 50 and 100 ug/mL in comparison to the control (CTL). No significant differences were observed in macrophages stained with PI dyeBack to article page
