OBJECTIVE
To investigate molecular mechanisms underlying in the treatment of inflammatory bowel disease by Pulsatilla decoction.
METHODS
Wistar male rats were randomly divided into control group, model group, model + positive control group (mesalazine), traditional Chinese medicine treatment group, in addition, the Chinese medical treatment group was divided into middle and high dose group ( n = 8). Intragastric administration was used in the positive control group and traditional Chinese medicine treatment group. The expression of Smad7 and p-Smad3 in the colons were detected by immunohistochemistry and Western blot.
RESULTS
Compared with the model group, positive medicine and traditional Chinese medicine group, especially high-dose group, could effectively inhibit the expression of Smad7, while enhancing the p-Smad3 expression.
CONCLUSIONS
The activation of TGF-beta1/Smad3 signaling pathway may be the molecular mechanism underlying in the anti-inflammatory effect of inflammatory bowel disease by Pulsatilla decoction.
