This study characterized cardiac troponin T (cTnT) appearance and associated histological evidence of reversible or irreversible changes in myocardial ultrastructure, determined via electron microscopy, in rats undertaking isoproterenol (ISO) infusion or an endurance exercise challenge. Male rats were randomized into ISO and exercise groups. In ISO trials rats were killed 5 h (ISO-5H) and 24 h ...
beta-Adrenergic agonist, isoproterenol (ISO), is a potent relaxant of tracheal smooth muscle and inhibits carbachol-induced contraction. The effect of ISO on intracellular free Ca2+ concentration ([Ca2+]i) was examined in bovine tracheal smooth muscle strips, employing aequorin as Ca2+ indicator. Surprisingly, 10 microM ISO induces a 5-fold increase in [Ca2+]i which then gradually declines but ...
RATIONALE Catecholamines increase cardiac contractility, but exposure to high concentrations or prolonged exposures can cause cardiac injury. A recent study demonstrated that a single subcutaneous injection of isoproterenol (ISO; 200 mg/kg) in mice causes acute myocyte death (8%-10%) with complete cardiac repair within a month. Cardiac regeneration was via endogenous cKit(+) cardiac stem cell-m...
