Criteria for histopathological scoring of the colon tissue of the mice

Severity of inflammation Depth of lesion Crypt destruction Lesion range Score
Normal tissue No lesion No damage No lesion 0
Mild inflammation Lesions invade lamina propria Basal 1/3 recess is destroyed 1%-25% 1
Severe inflammation L esions invade submucosa Basal 2/3 recess is destroyed 26%-50% 2
L esions invade the mucosa Only superficial epithelium is intact 51 %-75% 3
All crypts and epithelium are destroyed 76%-100% 4
