Plasma 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...

Plasma cyclic nucleotide levels in acute leukemia patients.

To verify the clinical usefulness of extracellular cyclic nucleotide determination as a tumor marker, plasma cyclic AMP (cAMP) and cyclic GMP (cGMP) levels were measured in 70 normal subjects and 173 acute leukemia patients studied in different stages of their disease. Mean plasma cAMP levels were similar in leukemic and normal subjects, although in 48 patients in the active stage of the diseas...

ment and increased linearly for 72 h. Receptor expression was dependent on new protein synthesis. At 48 h, Scatchard analysis demonstrated 2.4 X 105 receptors/ cell with a KD of 1.3 nM. In contrast to induction of HL60 differentiation by dimethyl sulfoxide, retinoic acid, or phorbol myristate acetate, the developmental programs initiated by agents that raised intracellular adenosine 3'5'-cyclic...

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...

Plasma 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...
