Methods: (1) The mucosa biopsy specimens were collected from 40 patients with ulcerative colitis, and normal mucosa from 20 colon cancer cases served as control. Effects of wortmannin on expression of TNF-alpha in intestinal mucosal specimens from patients with ulcerative colitis were determined on the condition of tissue culture.
