Expression of matrix metalloproteinase-1 and tissue inhibitor of metalloproteinase-1 in ulcerative colitis

Table 6 Intensity of TIMP-1 expression in samples from different areas of colon in UC

Samples	-	+	++	+++	P value
Ulcerated area	4	7	9	10	< 0.05ac
Inflamed area	4	8	13	5	< 0.05ace
Non-inflamed area	6	19	5	0	> 0.05
Normal controls	5	11	4	0

^aP < 0.05 vs normal controls,

^cP < 0.05 vs non-inflamed area,

^eP < 0.05 vs ulcerated area.
