Abstract:
Objective To observe the influence of Sishen Pill on the NF-κB p65 mRNA and protein expressions of colonic mucosa in rats with experimental ulcerative colitis (UC), and identify its underlying mechanism of action. Methods The experimental rats were divided into blank group, model group, Sishen Pill group and SASP group. The models were prepared by TNBS/ethanol enema. Sishen Pill group was intragastrically administrated by Sishen Pill extract 5 g/kg, SASP group by SASP 0.3 g/kg, and blank group and model group by equal volume of normal saline. The morphological injury of colonic mucosa was observed and scored with the naked eyes, and NF-κB p65 gene and protein expression were detected by RT-PCR and immunohistochemical method. Results Inflammation and ulceration on the colonic mucous membrane were found in the model group by naked eyes, and had significant difference with the blank group (P<0.05). The relative expression amount of NF-κB p65 gene and protein of colonic tissues were increased in the model group compared with the blank group (P<0.01). Compared with the model group, the relative expression amount of NF-κB p65 gene and protein in Sishen Pill group were decreased (P<0.05, P<0.01). Conclusion Sishen Pill has effect for treating UC, which is probably related to the activation of NF-κB signal transduction pathway.
