The effect of Sal B on the activity of MMP-2 in kidneys of model rats. The activity of MMP-2 was assessed by gelatin zymography. The results showed the activity of MMP-2 was increased in rats of model group when compared with that of normal group. Sal B significantly down-regulated the activity of MMP-2. **P < 0.01 vs. normal; # P < 0.05 vs. Model.
