Histological Scoring System (Microscopic Evaluation of Inflammation)

Microscopic Features	Score
No signs of inflammation	0
Very low level of inflammation	1
Low level of leukocyte infiltration	2
High level of leukocyte infiltration, high vascular density, thickening of the colon wall	3
Transmural infiltration, loss of goblet cells, high vascular density, thickening of the colon wall	4
