摘 要:目的:比较乌梅丸与西药柳氮磺胺吡啶SASP组对溃疡性结肠炎大鼠结肠组织NF-κB p65疗效的大小,并分析其作用机制.方法:应用2,4.二硝基氯苯(DNCB)免疫加醋酸局部灌肠法建立UC大鼠模型,将56只健康SD大鼠(雌雄各半),按雌雄随机分4组,分别为乌梅丸组、SASP组、模型组和正常组,分别观察治疗后大鼠结肠黏膜组织匀浆NF-κB p65的变化.结果:在正常结肠组织中NF-κB p65无或仅有弱阳性表达,模型组结肠黏膜组织NF-κB p65阳性细胞表达率明显高于正常组(45.67%±4.25%vs 10.45%±5.20%,P<0.05),乌梅丸(26.32%±9.65%)和SASP(31.23%±5.18%)组阳性细胞率则明显低于模型组,乌梅丸组阳性细胞率较SASP组更低.结论:NF-κB与UC发病关系密切,乌梅丸可能通过抑制NF-κB p65活性调节免疫功能达到治疗的目的.AIM: To compare the effects of Wumeiwan (WMW) and solfasalazine (SASP) on NF-κB p65 in colon tissue of rats with ulcerative colitis (UC) and to analyze their mechanism of action. METHODS: A model of UC was induced by administration of dinitro-chlorobenzene (DNCB) and acetic acid. Fifty-six SD rats (28 males and 28 females) were randomly divided into normal control group (n = 14), model group (n = 14), SASP group (n = 14), and WMW group (n = 14). Changes of NF-κB p65 in rat colon tissue were observed after treatment with DNCB and acetic acid. RESULTS: NF-κB p65 was not expressed or weakly expressed in normal colon tissue. The positive expression rate of NF-κB p65 was significantly higher in WMW and SASP groups than in normal control group(26.32% ± 9.65%, 31.23% ± 5.18% vs 45.67% ±4.2%, P 〈 0.01). The positive expression rate of NF-κB p65 was significantly lower in WMW group than in model group. There were significant differences between WMW and SASP groups (P 〈 0.05). CONCLUSION: NF-κB is closely related with the development of UC. WMW can treat UC by suppressing the activity of NF-κB p65.
