Moxibustion treatment modulates the gut microbiota and immune function in a dextran sulphate sodium-induced colitis rat model

Figure 3 Histopathological scores for colon tissue in the different groups. HC: Healthy controls; UC: UC model group; UC-7: UC model with seven days of moxibustion; UC-14: UC model with fourteen days of moxibustion; UC-W: UC model with mesalazine gavage; HC-7: Healthy controls with seven days of moxibustion; HC-14: Healthy controls with fourteen days of moxibustion. The histopathological scores in the UC group were significantly increased compared with the HC group (P < 0.01). After treatment, the scores were decreased in the UC-7, UC-14, UC-W, HC-7 and HC-14 groups compared with the UC group (P < 0.01). ^bP < 0.01 vs the HC group; ^dP < 0.01 vs the UC group.
