Angiopoietin and vascular endothelial growth factor expression in colorectal disease models

Table 1 Calculation of disease activity index

Score	Parameter
	Weight loss	Stool consistency	Perianal bleeding
0	None	Normal	None
1	1%-5%
2	5%-10%	Pasty stools	Occult bleeding
3	10%-20%
4	> 20%	Diarrhea	Gross bleeding

Disease activity index was calculated as cumulative score of the three parameters.

Table 2 Disease activity index, colorectal length, and pathology score in each group (mean ± standard deviation)

Group	Disease activity index	Colon length (cm)	Pathology score
Colorectal cancer	3.89 ± 0.91a	8.29 ± 0.21a	5.56 ± 0.12a
Ulcerative colitis	3.67 ± 0.47a	8.31 ± 0.86a	5.23 ± 0.41a
Control	0.00 ± 0.00	12.34 ± 0.12	0.00 ± 0.00

^aP < 0.05 vs control.
