Figure 2: DHI treatment can reduce inflammation in adhesion tissue in the rat model 7 days after operation (; compared with the control group, and ). (a) HE staining of each group at 100x magnification. The top right corner is shown at 200x magnification. The brackets indicate tissue with adhesion. (b) The inflammatory score of each group based on HE staining (compared with the control group, and , normal distribution, one-way ANOVA). (c) The TNF-α expression in each group (compared with the control group, , abnormal distribution, Kruskal-Wallis test). (d) The TGF-β expression in each group (compared with the control group, , abnormal distribution, Kruskal-Wallis test).
