Figure 4From: Anti-inflammatory effects of clarithromycin in ventilator-induced lung injuryMatrix metalloproteinase activity. Both MMP-9 (A) and MMP-2 (B) increased in all the experimental groups submitted to high-pressure ventilation. MMP-9 levels were higher in levofloxacin-treated animals, compared to the other treatment groups and irrespective of the ventilatory strategy. A representative zymography is shown in panel (C).Back to article page
