[Ligands of opioid and sigma receptors and correction of cardiac electrical instability in post-infarction cardiosclerosis]
Abstract
Peripheral administration of the mu- or kappa-receptor agonists or sigma-receptor antagonists produced a significant receptor-dependent increase in the ventricular fibrillation threshold in rats with postinfarction cardiosclerosis. The effect was not observed upon administration of the epsilon-receptor agonist beta-endorphin. The receptor and molecular mechanisms of the observed effects are discussed.
