Gadolinium chloride decreases macrophage secreted cytokines after ischemia and reperfusion in rats. (A) Representative blots from cytokine arrays from control hearts vs. GdCl3-treated hearts. The GM-CSF and IL-1 dots are indicated. Dots were quantitated and normalized to the positive control dots (lower left 4 dots) and results displayed above (B). Data mean ± SD, n = 3-4/gp, * = p < 0.05, GdCl3 vs. control, += macrophage secreted cytokines, ‡ = cardiomyocyte secreted cytokines.
