Sequential estimation of plasma catecholamines in exercise-induced asthma.
T h e physiologic effects of circulating plasma catecholamines m a y be responsible for the observed clinical and pathologic findings in exercise-induced asthma. Eleven patients with as thma were given a gradual increase in exercise over 1 2 minutes to a mean total of 5 8 0 0 K p m . P l a s m a catecholamines were measured in the resting state, at the peak of exercise and ten minutes after the...
متن کاملPlasma catecholamines during exercise-induced bronchoconstriction in bronchial asthma.
Plasma levels of adrenaline and noradrenaline during and after submaximal exercise in patients with bronchial asthma were investigated. Three groups were studied comprising 10 patients with exercise-induced bronchoconstriction (EIB), 10 asthmatic patients without EIB and four normal control subjects. Plasma catecholamines were measured at rest, at the end of exercise, and five and 15 minutes af...
متن کاملCirculating catecholamines in exercise and hyperventilation induced asthma.
Plasma noradrenaline, adrenaline, and cyclic 3'5' AMP (cAMP) were measured in seven asthmatic patients with known exercise-induced bronchospasm and six matched non-atopic control subjects during a standard treadmill exercise test and then during matched isocapnic hyperventilation. Normal subjects showed a 5.5 fold rise in noradrenaline and a 3.2 fold rise in adrenaline during exercise compared ...
متن کاملExercise-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 کاملPlasma cyclic nucleotide levels in exercise-induced asthma.
It is known that sympatho-adrenal control of airways is increased in asthma since beta blockade can cause severe bronchoconstriction in asthmatic individuals. It has not been established whether an altered catecholamine response to exercise plays any part in the production of the common symptom of exercise-induced asthma (EIA). We have investigated this indirectly by measuring arterial plasma c...
