Regulatory Effect of Sijunzi Tang and Its Single Herbs on Intestinal Flora in Rats with Spleen Deficiency
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:
2
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(0
th
day)
post-modeling(11
th
day)
and post-treatment(18
th
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:
2
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 11
th
day(
P
<
0.05
P
<
0.01)
this indicated that the spleen-deficient model was successfully constructed. On the 18
th
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(
P
<
0.01)
these indexes in feces of SJZT group
Ginseng Radix et Rhizoma group and Poria group were significantly increased(
P
<
0.05
P
<
0.01)
while Glycyrrhizae Radix et Rhizoma Praeparata cum Melle group only increased diversity index of intestinal flora(
P
<
0.05).
Conclusion:
2
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.
