ABSTRACT
The aim of this paper was to investigate the anti-inflammatory effect of Tripterygium wilfordii processed with licorice on DSS-induced ulcerative colitis( UC) mice and its regulation on intestinal immune system. In this study,a DSS-induced animal model of UC mice was established,with mesalazine( Mes) as a positive drug. The pharmacodynamic effects of low( PT1) and high( PT2)doses of T. wilfordii processed with licorice were analyzed by disease activity index( DAI),colon length and colon histopathological score in mice. By detecting the expression levels of TNF-α and IL-6 cytokines in the serum of mice,immunohistochemical CD3+T and Fox P3+Treg staining in the colon of mice,the anti-inflammatory and immunoregulatory effects of T. wilfordii processed with licorice on UC mice were analyzed. The hepatotoxicity of each dose of T. wilfordii processed with licorice was also analyzed by HE staining in liver tissue of mice and ALT and AST levels in serum. The results showed that the colitis symptoms of the mice in the PT1 group and the PT2 group were alleviated,the inflammatory cell infiltration was reduced. And the expression of inflammatory factors was decreased,the difference was statistically significant compared with the model group( P<0. 05). The HE staining and ALT and AST levels in the high dose group and low dose group were not significantly different from those in the normal group. The results showed that T. wilfordii processed with licorice has the anti-inflammatory and immunomodulatory effects on UC mice,and the dose did not show significant hepatotoxicity.
