Figure 2 Expression of hydroxyindole-O-methyltransferase in colonic mucosa in healthy subjects (C), patients with ulcerative proctitis and ulcerative colitis. Healthy subjects [control group (C); n = 30]; Patients with acute phase of ulcerative proctitis (UP; n = 30); Patients with acute phase of ulcerative colitis (UC; n = 30); Differences between group C and UP ^bP < 0.01; Differences between group C and UC ^dP < 0.01. HIOMT: Hydroxyindole-O-methyltransferase.
