The ratio of mast cell degranulation in the colonic mucosa. Under an electron microscope, mast cell degranulation was categorized into piecemeal degranulation (PMD) and anaphylactic degranulation (AND). Percentage of degranulation was calculated with the number of total granules and the number of PMD or AND. Student t test was performed with the data between groups. *, P < 0.05, compared with PMD of normal group (A). #, p < 0.05, compared with PMD of normal group (B). $, p < 0.05, compared with AND of the normal group (A). &, p < 0.05, compared with AND of the normal group (B). @, p < 0.05, compared with PMD of UC only group (A). +, p < 0.05, compared with AND of UC only group (B).
