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.
