Abstract:
Objective On the basis of previous research, we intended to further explore whether Kuijietong chieving the inhibitory effect on inflammatory action in ulcerative colitis(UC) through inhibiting the phosphorylation of IkappaBalpha/NF-kappaB p65(p-IκBα/NF-κB p65). Methods UC rat model was established by free drinking of dextran sulfate sodium(DSS) water. SD rats were randomly divided into normal group, model group, high-dose Kuijietong group(at intragastric dosage of 15 g·kg-1·d-1), low-dose Kuijietong group(at intragastric dosage of 5 g·kg-1·d-1), SASP group (at intragastric dosage of 0.3 g·kg-1·d-1). After treatment for 2 weeks, the expression levels of p-IκBα/IκBα and p-NF-κB p65/NF-κB p65 in colon tissues were determined by Western blotting method. Results The expression levels of p-IκBα/IκBα and p-NF-κB p65/NF-κB p65 in high-dose Kuijietong group were decreased significantly as compared with those in the model group and western medicine group, the difference being statistically significant(P<0.001). Conclusion Kuijietong has protective effects against inflammation in UC through blocking the activation of NF-κB classic inflammatory pathway, and the effect of high dosage of Kuijietong is the strongest.
