Evaluation of stool consistency after TNBS induction and ZD treatment in UC rats

Stool Consistency	Day 2	Day 5	Day 8
Normal	0 ± 0	0 ± 0	0 ± 0
Model	1.15 ± 0.45*	2.25 ± 0.25**	2.85 ± 0.36**
SASP	1.15 ± 0.5**	2.10 ± 0.35*	1.15 ± 0.15**
Low dose	1.15 ± 0.42*	2.20 ± 0.35*	2.55 ± 0.35*
Moderate dose	1.10 ± 0.35*	2.05 ± 0.25*	2.15 ± 0.25*
High dose	1.05 ± 0.25**	1.90 ± 0.15*	1.10 ± 0.25**

Scoring of stool consistency: 0= no diarrhea; 1= mild; 2= severe; 3= severe and bloody diarrhea. The scores of each group were the average of 6 animals.

^*P<0.05 compared to model group.

^**P<0.01 compared to model group.

ZD, Zhenrenyangzang decoction; SASP, salazosulfapyridine.
