Blockade of hyperkalemia and hyperglycemia induced by epinephrine in frog liver and in cats.
CRAIG, ALBERT B., JR. AND PHILIP L. MENDELL.BZ~&Z& of hyperkalemia and hyperglycemia induced by eljinephrine in frug liver pnd in cats. Am. J. Physiol. I g7( I) : 52-54. I g5g.-Dihydroergotamine (DHE) and Dibenamine are both known to block the hyperkalemic response to intravenously injected epinephrine. By simultaneously sampling blood from the hepatic vein and from the carotid artery it was po...
متن کاملSynergistic interactions of physiologic increments of glucagon, epinephrine, and cortisol in the dog: a model for stress-induced hyperglycemia.
To evaluate the role of anti-insulin hormone actions and interactions in the pathogenesis of stress-induced hyperglycemia, the counterregulatory hormones, glucagon, epinephrine, and cortisol were infused alone as well as in double and triple combinations into normal conscious dogs in doses that were designed to simulate changes observed in severe stress. Infusion of glucagon, epinephrine, or co...
متن کاملRole of epinephrine-mediated beta-adrenergic mechanisms in hypoglycemic glucose counterregulation and posthypoglycemic hyperglycemia in insulin-dependent diabetes mellitus.
Initially euglycemic (overnight insulin-infused) patients with insulin-dependent diabetes mellitus (IDDM), compared with nondiabetic controls, exhibit similar, but somewhat delayed plasma glucose nadirs, delayed glucose recovery from hypoglycemia, and posthypoglycemic hyperglycemia after the rapid intravenous injection of 0.075 U/kg of regular insulin. These abnormalities are associated with an...
متن کاملCardiac epinephrine synthesis and ischemia-induced myocardial epinephrine release.
OBJECTIVE Phenylethanolamine-N-methyltransferase (PNMT), the enzyme that synthesizes epinephrine (EPI) from norepinephrine (NE) in the adrenal gland, is present in extra-adrenal tissues including heart. Ischemia evokes an excessive NE accumulation in the myocardial interstitial spaces. Therefore, cardiac PNMT activity with high NE levels may contribute to cardiac EPI synthesis and release evoke...
متن کاملVasopressin and epinephrine vs. epinephrine alone in cardiopulmonary resuscitation.
BACKGROUND During the administration of advanced cardiac life support for resuscitation from cardiac arrest, a combination of vasopressin and epinephrine may be more effective than epinephrine or vasopressin alone, but evidence is insufficient to make clinical recommendations. METHODS In a multicenter study, we randomly assigned adults with out-of-hospital cardiac arrest to receive successive...
