Figure 2: EG stands for experiment group; CG stands for control group; BT stands for “before treatment”. AT stands for “after treatment”. The average number of positive immunoreactivity particles for IgA, IL-1β, or IL-10 in colon mucosa was no significant difference before treatment between two groups. Two months after treatment, the average number of positive particles for IgA and IL-10 in colon mucosa in each group increased significantly (). Moreover, the average number of positive particles for IgA and IL-10 in experiment group was more than that in control group (). However, average number of positive particles of IL-1β was opposite to that of IgA and IL-10 ().
