The effect of C. ignea extract on lung matrix metalloproteinases (MMPs) in control and treated mice animals. (A): MMP-12 activity in lung tissues. (B): Gelatin polyacrylamide gel showing MMP-2 activity in lung tissues. (C): Densitometric analysis of MMP-2 activity in zymogram obtained by using an image analysis program; the levels are expressed in arbitrary units relative to the MMP-2 value in the control group. Data are presented as mean ± SE for six mice in each group. ^a P < 0.05 for comparison to control group (Group I), ^b P < 0.05 for comparison to B(a)P group (Group II).
