Fig. 5. Effect of fennel on MMP-9 activity in LPS-treated mice. Relative MMP-9 activity in BALF was analyzed by zymography followed by scanning densitometry. Data are reported as mean±S.E.M. (n=7~10 per group). ^##p<0.01, ^###p<0.001 compared with the vehicle group; ^*p<0.05, ^**p<0.01, ^***p<0.001 compared with the vehicle+LPS group.
