Study of the roles of caspase-3 and nuclear factor kappa B in myenteric neurons in a P2X7 receptor knockout mouse model of ulcerative colitis

Table 1 Changes in weight, stool consistency, and the presence of blood in the stool were scored for the ulcerative colitis model mice and mice that received intrarectal injection of 35% ethanol according to the following scale

Disease activity index		Score
A	Weight change (< 1%)	0
	Weight change (1%-2%)	1
	Weight change (2%-4%)	2
	Weight change (4%-6%)	3
	Weight change (> 6%)	4
B	Stool consistency (normal)	0
	Stool consistency (normal and well-formed)	1
	Stool consistency (pasty that did not stick to the anus)	2
	Stool consistency (loose stool)	3
	Stool consistency (diarrhea)	4
C	Rectal bleeding (absent)	0
	Rectal bleeding (+)	1
	Rectal bleeding (++)	2
	Rectal bleeding (+++)	3
	Rectal bleeding (gross bleeding)	4

A: Weight; B: Stool consistency; C: Presence of blood in the stool.
