Assessment of Ameliorative Effect of Myrica esculenta in a DSS-Induced Murine Model against Ulcerative Colitis

Table 2

Histopathological scoring system.

Histopathological score	Description
0	No sign of inflammation, intact crypt, and no ulceration foci.
1	Mild mucosal inflammation and damage to crypt and 1-2 ulceration foci.
2	Moderate inflammation that extends up to the submucosal layer, increased damage to crypt, and 3-4 ulceration foci.
3	Severe inflammation that extends to the tunica muscularis, entire damage to crypt, and immense ulceration.
4	Severely chronic inflammation and erosion that leads to change in epithelial surface.
5	Concurrent erosion of colonic epithelium.

Histopathological scoring system is followed from Kim et al. [18].
