Role of moxibustion in inflammatory responses during treatment of rat ulcerative colitis

Figure 2 Comparison of disease activity index in ulcerative colitis rats before and after moxibustion treatment. Ulcerative colitis (UC) rats in the waiting list control (WLC) group did not receive moxibustion treatment. UC rats in the 3-min moxibustion (3M), 6-min moxibustion (6M) and 9-min moxibustion (9M) groups received 3, 6 and 9 min, respectively, in each treatment session. Values are the average of 14 sessions. Before treatment, there was no significant difference in disease activity index (DAI) among the groups. After treatment, significant differences (P < 0.05) in disease activity were found. In the 3M, 6M and 9M groups, DAI markedly decreased after moxibustion treatment. Error bar represents SD, and significance was assessed using least significant difference.
