title: [Preparation and clinical assays of Cl esterase inhibitors].
abstract: Seven preparation of Cl-estrase inhibitor (Clinh) were prepared from the serum form which factor IX had been absorbed previously. Despite always the same technique and conditions of isolation the degree of Clinh recovery differed, being sometimes fairly low, and ranging from 24% to 56% in relation to the initial plasma. The preparations contained cartain amounts of other proteins from the groups of alpha- and beta-globulins, particularly coeruloplasmin and components of complement C3, C4 and C9. The concentration of these components was low in relation to the concentration of the inhibitor. Some preparations contained also low amount of albumins. The preparation (about 20 thousand Clinh units) was transfused to a patient with congenital deficiency of Cl-esterase inhibitor at the time free of symptoms. The investigation of the blood obtained 30 minutes after transfusion showed complete inhibition of C-L-esterase. Administration of the preparation to the patient at the time of acute oedema caused in 5 episodes rapid regression of oedema or inhibition of its increase, in two cases no evident positive effect was obtained.
