Table 1 Microscopic assessment of histologic changes in DSS colitis

A: Grade of crypt lesion	Score
Intact crypt	0
Grade 1: Loss of the basal third	1
Grade 2: Loss of two thirds	2
Grade 3: Loss of entire crypt	3
Grade 4: Erosion	4
B: Extension of each grade of crypt lesion as % of total mucosal surface	0-100
Crypt lesion score	Σ (A × B)
Grade of inflammation, epithelial regeneration or crypt distortion	Score
Absent	0
Mild	1
Moderate	2
Severe	3

Crypt lesion, acute and chronic inflammation, epithelial regeneration and crypt distortion are scored separately.
