Combination treatment of MKN45, KATO-III, HT29-5F12, HT29-5M21 and LS174T cells with bromelain and NAC. Cells were treated for 72 hours with three concentrations of each agent on their own and in combination. In general, growth-inhibitory effects of combination therapy were significantly more potent than those induced by single agent treatment. Significant changes (p <0.05) are marked by bold (*) and non-bold (*) asterisks when single agent bromelain and NAC are considered as control, respectively.
