Method The rat model of ulcerative colitis was induced with2,4,6 trinitrobenzene sulfonic acid. 方法采用三硝基苯磺酸法制备大鼠实验性溃疡性结肠炎模型。
Methods: The chemical model was induced by trinitrobenzene sulfonic acid(TNBS) and the mechanical model was induced by colon irritation (CI) during postnatal development. 方法:化学造模采用TNBS模型,物理模型采用新生鼠发育期肠激惹方式诱导模型。
