Changes in Sympathetic Innervation of the Heart in Rats with Experimental Myocardial Infarction. Effect of Semax

The effect of peptide Semax on remodeling of cardiac sympathetic innervation was examined in rats with experimental myocardial infarction. In 28 days after ischemia/reperfusion injury, Semax diminished the growth of sympathetic innervation of ventricular septum, although it produced no effect on the density of β1 and β2 adrenoceptors.
