Objective: To observe the toll like receptor(TLR)4 mRNA expression decoction on rat diarrhea type irritable bowel syndrome (D-IBS)colon tissue model by Fuzi Lizhong(FZLZ) decoction. Method: SPF 50 rats were randomly divided into normal group
model group
FZLZ high and low dose group(30
15 g·kg-1)
pinaverium bromide group(30 mg·kg-1). IBS rat model was made by restraint stress combined with ig rhubarb. After modeling
corresponding drugs were given at the dose
once a day for 14 days. TLR4 mRNA expression was observed through PCR method. Result: The expression of TLR4 in the model group (1.229±0.172)was higher than that in the control group(1.109±0.062)(P<0.01). While the expression of TLR4 in the FZLZ decoction was similar to normal groups
there was no significant difference between the high (1.068±0.056) and low (1.067±0.071)dose group
pinaverium bromide group(1.205±0.290) compared with the normal group TLR4 expression increased (P<0.01). Conclusion: FZLZ decoction may maintain intestinal homeostasis by enhancing the whole body tolerance
and decreaseing the expression of TLR4 and immune response.
