Figure 8 Tumor necrosis factor-α level in colonic tissue. Data are presented as mean ± SD, ^aP < 0.05, ^bP < 0.01 vs control, Statistical comparisons were performed using One-way ANOVA followed by Dunnett’s test using GraphPad Prism 5.0.; ^cP < 0.05 vs IBS; ^eP < 0.05 vs TXYF, difference between SGD-M and TXYF was analyzed by the Student’s t test using GraphPad Prism 5.0. (n = 4). TNF: Tumor necrosis factor; SGD: Shugan decoction; IBS: Irritable bowel syndrome; TXYF: TongXieYaoFang.
