Pingkui Enema Alleviates TNBS-Induced Ulcerative Colitis by Regulation of Inflammatory Factors, Gut Bifidobacterium, and Intestinal Mucosal Barrier in Rats

Table 3

Evaluation of pathological score. The total score was the sum of epithelial score and inflammatory cell infiltration.

Score	Epithelial cells	Inflammatory cell infiltration
0	Normal form	No infiltration
1	Goblet cell loss	Infiltration in the basal layer of crypt
2	Large area loss of goblet cells	Infiltration reaches the mucosal muscle layer
3	Crypt cells loss	Infiltration deep into the mucosal muscle layer, accompanied by mucosal thickening and edema
4	Large area loss of crypt cells	Infiltration to the submucosa
