DAI score
Twenty-four hours after the C. rodentium model was established, mice in the control colitis group manifested lethargy, sluggishness, appetite loss, rough hair, diarrhoea, bloody stools or faecal occult blood (+∼++), and weight loss. These symptoms were most evident 3 days after the start of modelling. All the symptoms of mice of the TS+CR group were less severe than those observed in the CR group and were significantly different on days 1 and 3 (P <0.05). The conditions of the surviving mice in both groups started to gradually improve on day 4, and the mice were relieved on day 7. At this time, in contrast to the mice in the CR group, the mice in the TS+CR group were still recovering. The DAI scores of the three groups at different time points are shown in Fig. 3.
