Electrical resistance in human ileal mucosa. (A) Electrical resistance (TER) during vehicle (control) experiments and during exposure to sodium caprate (C10) in mucosa from colon cancer patients (n=8; open symbols) and non-inflamed mucosa from Crohn's disease patients (n=5; filled symbols) mounted in Ussing chambers. *p<0.05 between groups, Mann-Whitney. (B) TER in inflamed mucosa from patients with Crohn's disease (n=4; filled symbols) mounted in Ussing chambers. Broken lines indicate the curves of non-inflamed mucosa from Crohn's disease patients and colon cancer patients in (A). *p<0.05 compared with non-inflamed mucosa, Mann-Whitney. The variables are expressed as per cent of initial values (median and 25–75th interquartile range). Washout of vehicle and C10 was performed at 10 minutes (arrows).
