摘 要:目的:探讨山芝麻水提物对大鼠溃疡性结肠炎(UC)的药效作用及其机制。方法:将SD大鼠随机分成6组(正常对照组、模型组、柳氮磺胺吡啶组及山芝麻高、中、低剂量组),采用三硝基苯磺酸(TNBS)灌肠法,制备溃疡性结肠炎大鼠模型。第2天开始灌胃给药,在第3周处死动物后,观察药物对大鼠血清中白细胞介素-10(IL-10)、白细胞介素-6(IL-6)、肿瘤因子-α(TNF-α)表达水平以及结肠组织病理改变的影响。结果:山芝麻水提物能显著升高溃疡性结肠炎大鼠血清中抑炎因子IL-10水平,降低其促炎因子IL-6、TNF-α水平,并改善大鼠的组织学损伤和症状。结论:山芝麻水提物能平衡溃疡性结肠炎大鼠血清中炎症因子水平,并改善其病理组织损伤和症状。Objective : To investigate the effect of aqueous extract of Helicteres angustifolia ( AEHA ) on rats with ulcerative colitis (UC) and its mechanism. Methods : SD rats were randomly divided into 6 groups : normal control group, the model group, SASP group and 21.6,10. 8,5. 4 g/kg AEHA group with 10 rats in each group. UC was induced by clyster with 2,4,6-trinitrobenzesulphonic acid(TNBS)in rats. Rats were given AEHA by gavage for 3 weeks,and sacrificed at day 22nd to determine the expressions of IL-10,IL-6 and TNF-a in blood. Colon tissue pathological changes were investigated. Results:Compared with the control group, the expression of IL-10 was increased, the expressions of IL-6 and TNF-a were decreased in AEHA treatment groups. The colon tissue damages and the symptoms of UC rats were improved. Conclusion:AEHA can keep balance of inflammatory factors in blood of UC rats, and improve it's colon tissue damages and symptoms.
