[Characteristics of the action of euphylline and the activity of forms of cAMP phosphodiesterase in lymphocytes of patients with bronchial asthma].
Two forms of cAMP phosphodiesterase were isolated from lymphocytes by using centrifugation in sucrose density gradient. The activities of both forms do not differ in healthy persons and in patients with bronchial asthma during asphyxia-free period. During the attack the activity of the high molecular form of the enzyme increases. Euphylline exerts the inhibitory effect on the activity and consequently on the general activity of the enzyme.
