ABSTRACT
Objective:
To investigate the regulatory effect of Sijunzi Tang(SJZT) and its single herbs(Ginseng Radix et Rhizoma, Glycyrrhizae Radix et Rhizoma Praeparata cum Melle, Atractylodis Macrocephalae Rhizoma and Poria) on intestinal flora in spleen-deficient rats.Method:
Normal rats were randomly divided into the blank group, model group, Zhengchangsheng granules group, SJZT group and each single herb group, rats were orally administered Sennae Folium decoction to induce diarrhea for ten consecutive days to establish a spleen-deficient model(distilled water for the blank group), then treated with the corresponding drugs for seven consecutive days(distilled water for the blank group and the model group). Fresh feces were collected on pre-modeling(0th day), post-modeling(11th day), and post-treatment(18th day). Short-chain fatty acids(SCFAs) in feces were acidified by sulphuric acid and extracted by diethyl ether, then determined by gas chromatography. The structural change(diversity and similarity) of intestinal flora in feces was analyzed by 16S rDNA-polymerase chain reaction(PCR)-denaturing gel gradient electrophoresis(DGGE) technique.Result:
Compared with blank group, the contents of SCFAs as well as diversity and similarity indexes of intestinal flora in feces of all administered groups were significantly decreased on the 11th day(PPth day, compared with model group, the contents of SCFAs as well as diversity and similarity indexes of intestinal flora in feces of Atractylodis Macrocephalae Rhizoma group were significantly increased(PPPPConclusion:
Ginseng Radix et Rhizoma, Atractylodis Macrocephalae Rhizoma and Poria are the single herbs responsible for the regulatory effect of SJZT on intestinal flora in spleen-deficient rats, and Atractylodis Macrocephalae Rhizoma may play a major role.
