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.

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.

Figure 4 Correlation between the number of enterochromaffin cells and excretion of 6-sulfatoxymelatonin in patients. A: With ulcerative proctitis (group II); B: with ulcerative colitis (group III). The number of enterochromaffin cells was counted in 10 fields in each bioptate at × 200 magnification; y: Linear regression equation; r: Pearson's correlation coefficient; 6-HMS: 6-sulfatoxymelatonin; EC: Enterochromaffin cells.
