Changes in nitric oxide synthase concentration in colonic myenteric tissue and serum. A: Comparison of nitric oxide synthase (NOS) concentration in colonic myenteric tissue of rats in the four groups showing statistically significant differences between EG groups and CG group (bP < 0.0001), and between EG2-3 groups and EG1 group (aP < 0.05); B: Comparison of NOS concentrations in the serum of rats in the four groups showing statistically significant differences between EG groups and CG group (bP < 0.0001), and between EG2-3 groups and CG group (aP < 0.05). CG: Control group; UC: Ulcerative colitis; NOS: Nitric oxide synthase; L-NMMA: NG-monomethyl-L-arginine monoacetate; EG1: UC group; EG2: UC + NOS agonist TP508TFA group; EG3: UC + NOS inhibitor L-NMMA group; NOS: Nitric oxide synthase.
