Objective To study the immune mechanism of Qingchang Effervescence Suppository for ulcerative colitis (UC). MethodsAll the rats were divided into normal control
model control
blank effervescence suppository
Qingchang Effervescence Suppository
Qingchang Suppository and Sulfasalazine groups. Tumor necrosis factor-α (TNF-α) and interleukin-13 (IL-13) in serum and colon supernatant were detected by enzyme-linked immunospecific assay. The expression of interleukin-8(IL-8) mRNA was detected by immunohistochemical method and in situ hybridization. Results As compared with normal control group
TNF-α in serum and the expression of IL-8 mRNA in colon mucosa of model control group increased significantly (P<0.05 or P<0.01). As compared with model control group
Qingchang Effervescence Suppository could reduce TNF-α and the expression of IL-8 mRNA significantly (P<0.05 or P<0.01)
but had no obvious effect on IL-13 (P>0.05). Conclusion Qingchang Effervescence Suppository has therapeutic effect on UC by inhibiting proinflammatory cytokine.
