Exercise-Induced Catecholamines
Catecholamines and platelet aggregation were studied in relation to physical fitness and psychologic traits of 48 young men at rest and after exercise challenge. Test scores were significantly associated with variables derived from the in vitro reactivity of blood platelets. Men characterized by high time urgency, impatience, haste and irritability had higher platelet counts in their whole bloo...
متن کاملCatecholamines and hypertension.
Ever since the demonstration that the active principle in the adrenal medulla can raise blood pressure (Oliver & Schafer, 1895), catecholamines have been implicated in the hypertensive diseases. The identity of noradrenaline as the neurotransmitter of sympathetic nerves (von Euler, 1946) and the demonstration that an injection of this catecholamine can produce cardiovascular changes similar to ...
متن کاملAccentuation by Catecholamines
Background. Efficient early diastolic filling is essential for normal cardiac function. Diastolic suction, as evidenced by a decreasing left ventricular pressure during early filling, could result from restoring forces (the release of potential energy stored during systolic deformation) dependent on myofilament relaxation. Although these restoring forces have been envisioned within individual m...
متن کاملCatecholamines regulate tumor angiogenesis.
Among the regulators of angiogenesis, catecholamine neurotransmitters are of recent interest because of their opposite roles in the regulation of tumor neovascularization. Norepinephrine and epinephrine by acting through specific adrenoceptors increase the synthesis of proangiogenic factors, and thereby, promote tumor growth. In contrast, dopamine acting via its specific D(2) receptors inhibits...
متن کاملEffects of Catecholamines
unteers to determine the effects of catecholamines and adrenergic-blocking agents on plasma and urinary levels of adenosine 3',5'-monophosphate (cyclic AMP) and guanosine 3',5'-monophosphate (cyclic GMP). Plasma cyclic AMP rose in response to infusions of the P-adrenergic agent, isoproterenol, or in response to infusions of either epinephrine or norepinephrine alone or -in combination with the ...
