實驗方案：

1. 將老鼠隨機分組；

2. 對照組每天飲用滅菌水；

3. 模型組每天飲用3.5%DSS至第6天,從第7天開始換為滅菌水,至第12天;

4. 實驗開始后,每天對老鼠進行觀察,稱重和評分；

5. 腸炎觀察指標包括： 體重； 拉稀程度；結腸病變情況等

Brief protocol of DSS induced IBD model

1. Mice 6-8 weeks old, female; Random divided into several groups;

2. DSS concentration 3.5%, control group treated with drink water;

3. DSS treatment DSS in drink water from Day 1 to Day 6 and changed to drink water from Day 7 to Day 12; 

4. Observation Mice are observed by measuring body weight twice a week in the first cycle. When obvious weight loss appears, mouse weight is measured on daily basis.
