Evaluation of enterochromaffin cells and melatonin secretion exponents in ulcerative colitis

Figure 1 Number of enterochromaffin cells in colonic mucosa in healthy subjects (C), 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. EC: Enterochromaffin cells.
