Evaluation of enterochromaffin cells and melatonin secretion exponents in ulcerative colitis

Figure 3 Urinary excretion of 6-sulfatoxymelatonin in healthy subjects (C) and patients with ulcerative proctitis and ulcerative colitis. The number of enterochromaffin cells was counted in 10 fields in each bioptate at × 200 magnification; 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. 6-HMS: 6-sulfatoxymelatonin.
