Repairing Effect of Huazhuo Jiedu Yukui Formula on Mucosal Damage of Rats with Ulcerative Colitis
摘要
Abstract
OBJECTIVE:To explore the repairing effect and mechanism of Huazhuo jiedu yukui formula on the mucosal dam-age of rats with ulcerative colitis (UC). METHODS:72 rats were randomly divided into blank group,model group,mesalamine group(positive control,0.3 g/kg),Huazhuo jiedu yukui formula low-dose,medium-dose,high-dose groups(5,10,20 g/kg),12 in each group. Except for blank group,other groups were induced UC model. After 4 d of modeling,rats in administration groups received related medicines,ig,blank group and model group received normal saline,ig,once a day,for 2 weeks. After administra-tion,disease activity index(DAI)and mucosal damage index(CMDI)of rats were observed;IL-8,TNF-α contents in serum and cyclooxygenase 2 (COX-2) expression in colon tissue were detected. RESULTS:Compared with blank group,DAI and CMDI scores in model group were increased;IL-8,TNF-α contents in serum were increased;COX-2 expression in colon tissue was en-hanced,with statistical significances (P<0.05). Compared with model group,DAI and CMDI scores in model group were de-creased;IL-8,TNF-α contents in serum were reduced;COX-2 expression in colon tissue was weakened,with statistical signifi-cances (P<0.05). Compared with mesalamine group, the above-mentioned indicators in Huazhuo jiedu yukui formula medi-um-dose,high-dose groups changed more obviously (P<0.05),and effects of Huazhuo jiedu yukui formula showed significant dose-effect relationship. CONCLUSIONS:Huazhuo jiedu yukui formula can improve disease activity status of UC rats and reduce colon mucosal damage,and the effects of medium-dose and high-dose Huazhuo jiedu yukui formula were better than mesalamine, which may be related to reducing inflammatory reaction and inhibiting COX-2 expression in colon tissue.关键词
