Biological actions of standard kimchi (sKimchi) and cpKimchi; comparison in an in vitro H. pylori cell model. A Cell survival assessed by MTT assay. MTT assay were performed on AGS cells (up) and RGM-1 cells (down) challenged with 1, 2.5, 5, or 7.5 mg/ml sKimchi and cpKimchi soluble extracts. Kimchi at concentrations greater than 5 mg/ml had significant cytotoxic effects only on AGS cells and not on RGM-1 cells even after kimchi treatment at concentrations greater than 5 mg/ml.
