[Adenosine deaminase activity in levamisole treatment of patients with rheumatoid arthritis]

Nine patients who fell ill with a classical or unequivocal rheumatoid arthritis were treated with 150 mg Levamisol a week. Before the beginning of the therapy and on the day after the fourth intake of medicaments the activity of the adenosine deaminase in lymphocytes, erythrocytes and in the plasma was determined. An influence on the enzyme activity by Levamisol could not be proved. Before as well as after the Levamisol therapy the enzyme activity in the erythrocytes was diminished.
