[Regulatory effect of Tripterygium wilfordii polycoride (TWP) towards TLR4/MyD88 independent pathway in TNBS/ethanol ulcerative colitis (UC) rat model].

In order to study the regulatory effect of Tripterygium wilfordii polycoride (TWP) towards TLR4/MyD88 independent pathway in TNBS/ethanol ulcerative colitis (UC) rat model, TNBS/ethanol enema was adopted to build TNBS/ethanol UC rat model. After the successful modeling procedure, 90 male Wistar rats are were divided into 6 groups, including namely normal group, model group, TWP low, middle, high dose groups (3, 6, 12 mg•kg⁻¹)and azathioprine (AZA) group (6 g•kg⁻¹), with 15 rats in each group. All rats in each group were administrated with corresponding medicines for 14 days.
