Figure 2 Histological observation and evaluation of colon tissue. A: Visual inspection of TNBS-induced colitis of colon tissue in rats and effect of rVIPa with different concentrations; B: Histologic score; C: Colon length. Data represent mean ± SEM (n = 8). ^aP < 0.05, ^eP < 0.001 vs control rats; ^cP < 0.05, ^dP < 0.01, ^fP < 0.001 vs TNBS-induced model rats.
