摘要: |
目的 研究康复新液对乙酸诱导大鼠急性溃疡性结肠炎(ulcerative colitis,UC)细胞因子的影响,并初步探讨其作用机制。方法 采用乙酸灌肠建立急性UC大鼠模型,除正常对照组及模型对照组外,其余各组分别灌肠给予结肠宁、康复新液2.50,1.25,0.625 g·kg-1,测定疾病活动指数(disease activity index,DAI)、结肠黏膜损伤指数(colon mucosa damage index,CMDI)及病理组织学评分(histopathological score,HS),采用酶联免疫吸附法检测大鼠血清中白介素-6(interleukin-6,IL-6)、C反应蛋白(C-reactive protein,CRP)、一氧化氮合酶(nitric oxide synthase,iNOS)以及结肠组织中表皮生长因子(epidermal growth factor,EGF)、环氧合酶-2(cyclooxygenase-2,COX-2)、髓过氧化物酶(myeloperoxidase,MPO)、iNOS的含量。结果 与模型对照组相比,结肠宁及康复新液高剂量能显著降低UC大鼠IL-6、CRP、iNOS、COX-2、MPO表达,升高EGF的表达水平(P<0.01),改善组织病变情况。结论 康复新液对乙酸诱导的UC有治疗作用,作用机制可能与下调大鼠体内炎症因子的表达量,上调EGF的表达量有关。 |

Abstract: |
OBJECTIVE To study the effect of Kangfuxin on cytokines of acute ulcerative colitis(UC) induced by acetic acid in rats and explore its mechanism. METHODS The acute UC rat model was established by acetic acid enema. Except the normal control group and model control group, the other groups were gavaged respectively by Jiechangning, Kangfuxin 2.50, 1.25, 0.625 g·kg-1. The disease activity index(DAI), colonic mucosa damage index(CMDI) and histopathological score(HS) were detected, interleukin-6(IL-6), C-reactive protein(CRP), nitric oxide synthase(iNOS) in serum and content of EGF, COX-2, MPO, iNOS in colon were determined by enzyme-linked immunosorbent method. RESULTS Compared with the model control group, Jiechangning and Kangfuxin with high dose could significantly reduce the expression level of IL-6, CRP, iNOS, COX-2, MPO and rise EGF in UC rats(P<0.01), and improve the pathological conditions of tissues. CONCLUSION Kangfuxin has therapeutic effect on acetic acid induced acute UC, and its mechanism may be related to down-regulating the expression of inflammatory factors and up-regulating the expression of EGF. |
