Effects of clarithromycin on VCAM-1 and MMP-9 expression levels in irradiated lungs of mice.

<p>(A) VCAM-1 expression in lungs of control (CTL), radiation only (RT), radiation + clarithromycin (RT+CLA), and clarithromycin only (CLA) animal groups. (B) MMP-9 expression in lungs of respective groups. Densitometry values were normalized to β-actin and data are presented as mean ± SEM (n = 2–6 mice per group). *<i>p</i><0.05 vs CTL mice; †<i>p</i><0.05 vs RT mice.
