Mechanism by Which Tong Xie Yao Fang Heals the Intestinal Mucosa of Rats with Ulcerative Colitis through the Hippo Pathway

Evaluation of histological scores.

Score (s)	Inflammatory cells	Tissue damage
0	Occasional inflammatory cells in the lamina propria	No mucosal damage
1	Increased numbers of inflammatory cells in the lamina propria	Discrete lymphoepithelial lesions
2	Confluence of inflammatory cells, extending into the submucosa	Surface mucosal erosion or focal ulceration
3	Transmural extension of the infiltrate	Extensive mucosal damage and extension into deeper structures of the bowel wall
