摘要:

为探索动物溃疡性肠炎的发生发展机制及其对机体的影响,以10日龄SPF雏鸡为研究对象,以2,4,6-三硝基苯磺酸(TNBS)为诱导剂,分别根据体重应用50、100、150 mg•kg-1的TNBS(50%乙醇稀释)通过灌肠途经建立TNBS诱导的雏鸡溃疡性结肠炎动物模型,进而分析TNBS对雏鸡溃疡性结肠炎发生的剂量效应。并对TNBS所致的溃疡性结肠炎雏鸡的临诊症状、眼观和病理组织以及体重等变化进行较全面系统的观察或检测,结果发现,100 mg•kg-1 TNBS为制备雏鸡溃疡性结肠炎动物模型的理想给药剂量,其能够得到理想的实验动物临诊症状和病理变化,同时对雏鸡的损伤在可控范围内,不会造成模型动物的大批死亡。本研究成功建立雏鸡溃疡性结肠炎病理模型,为进一步研究溃疡性结肠炎的发生发展奠定了基础。

Abstract:

In order to explore the mechanisms of ulcerative colitis in animals and its impact on body,10-day-old SPF chicks were used to build 2,4,6-trinitrobenzene sulfonic acid(TNBS) -induced model by clystering with TNBS in dose of 50,100,and 150 mg•kg-1,diluting with 50% ethanol,that can help us to analyzes the dose effect of TNBS-induced ulcerative colitis.Further observation and testing about the changes of the chicks’ clinical symptoms,pathology and body weight showed that the ideal medicine dose was 100 mg•kg-1 of TNBS,which can induce ideal changes of clinical symptoms and pathology in experimental animals without uncontrolled injury and massive death.This study successfully established chicks’ pathological model of ulcerative colitis which laid a foundation for deep research of the development of ulcerative colitis.
