Relationship of platelet retention in glass bead columns to the rate of aggregation with adenosine diphosphate and thrombin.

The initial rate of platelet aggregation induced by adenosine diphosphate and thrombin correlated with the number of platelets retained when samples of citrated blood from the same normal donors were passed through glass bead columns. The results support the view that the glass bead column method of measuring platelet ;adhesiveness' is influenced by platelet aggregation.

Adenosine diphosphate and the measurement of platelet adhesiveness.

Platelet adhesiveness to glass beads was measured in citrated blood at intervals up to two hours after the addition of adenosine diphosphate (A.D.P.). Adhesiveness increased for 15 minutes, fell towards the original level, and then steadily increased. The initial changes were associated with the formation and subsequent dispersal of platelet clumps. The sequence of events resembled the reported platelet aggregation, the disaggregation and secondary aggregation effect of A.D.P. and emphasizes the importance of a standard technique in the measurement of A.D.P.-induced platelet adhesiveness.

Coagulation studies in massive pulmonary haemorrhage of the newborn.

Coagulation studies were performed on two newborn infants with fatal massive pulmonary haemorrhage. The first showed a reduced level of plasma fibrinogen with defective thrombin-fibrinogen reaction, corrected by protamine, and defective thromboplastin generation. In the second case, a premature infant, the fibrinogen level was normal but there was a severe defect in thromboplastin generation with evidence of an inhibitor. A relationship between the pulmonary haemorrhage and coagulation defects is suggested but not established.

Defibrination syndrome with defective thrombinfibrinogen reaction reversible by protamine.

A patient with the obstetric defibrination syndrome successfully treated with human fibrinogen is described. The blood not only contained low levels of fibrinogen capable of clotting but also contained an inhibitor of the thrombin-fibrinogen reaction. This was neutralized in vitro with protamine but it was not heparin. Neither abnormality was detected by a latex agglutination test for plasma fibrinogen. The use of this test does not therefore exclude the diagnosis of the defibrination syndrome.
