Theophylline and forskolin-stimulated short circuit current (SCC) in human colon endoscopic biopsies from C-patients and N-patients is presented. Numbers in parenthesis are numbers of biopsy specimens and number of patients. Increases in SCC after stimulation with 400 μM theophylline (C-patients: 29,18), (N-patients: 7,4) and 1 μM forskolin (C-patients: 45,23), (N-patients: 13,7).
