Effect of Shaoyaotang on Expressions of AP-1 and TNF-α in Colon of Rats with Hygrothermal Ulcerative Colitis
To observe the effect of Shaoyaotang on mRNA and protein expressions of colon tissue activated protein-1 (AP-1) and tumor necrosis factor-
α
(TNF-
α
) of hot and humid-type intrinsic ulcerative colitis (UC) model in rats
in order to explore the mechanism of action of herbaceous peony decoction in the treatment of UC.
Method:
2
Totally 60 Wistar rats were randomly divided into blank group
model group
SASP group
and low
medium and high-dose Shaoyaotang groups. The damp-heat intrinsic UC rat model was replicated based on integrated disease and syndrome
namely
high-fat and high-sugar spicy food and immune complex method combined with 2
4
6-trinitrobenzene sulfolnic acid (TNBS) and ethanol complex method. After the successful modeling
low
medium and high-dose Shaoyaotang (6
12
24 g·kg
-1
) was given by gavage
and 1 g·kg
-1
dose of salazol sulfadiazine was given to by gavage. The blank group was given constant volume normal saline for 21 d. Real-time fluorescence quantitative polymerase chain reaction(Real-time PCR) was used to detect mRNA expressions of AP-1 and TNF-
α
in colon tissues
and Western blot was used to detect protein expressions of AP-1 and TNF-
α
in colon tissues.
Result:
2
Compared with the blank group
relative mRNA and protein expressions of AP-1
TNF-
α
in the model group were significantly increased (
P
<
0.05). Compared with the model group
mRNA and protein expressions of AP-1
TNF-
α
in the treatment groups were significantly decreased (
P
<
0.05).
Conclusion:
2
Shaoyaotang can inhibit the expression of TNF-
α
and stimulate AP-1 protein expression in rats with damp-heat UC.
