	MMP-1			MMP-2/-9
	Day 0	Day 3	Day 7	Day 0	Day 3	Day 7
Substrate ratio	103.8±2.6	97.7±2.1	46.2±0.4	106.1±2.7	100.0±6.4	40.6±6.5
NTP ratio	0.7±0.2	2.8±1.6	15.4±5.9	0.7±0.2	2.7±1.0	27.0±3.4

Substrate ratio denotes substrate concentration formed in blank dialysates divided by substrate concentration in a control solution. NTP ratio denoted NTP concentration formed in blank dialysate divided by corresponding substrate concentration in a control solution. Data represent mean±S.D., n=4.
