[Determination of the adrenergic response by measurement of catecholamines and activity of dopamine-beta-hydroxylase (D-beta-B) in arterial capillary blood].
Plasma dopamine-beta-hydroxylase activity and catecholamines (adrenaline and noradrenaline) level in venous blood taken from the cubital vein and in arterialized capillary blood taken from the ear lobe were measured before and after a maximal exercise on a treadmill in 14 healthy untrained volunteers. The authors have shown a good correlation between these parameters in venous blood and those in capillary blood. It is concluded that the determination of plasma dopamine-beta-hydroxylase activity and catecholamines level in arterialized capillary blood could be a valid measure of the sympathetic activity.
