Observations on the heparin neutralizing activity of outdated platelet concentrates.

A crude extract of outdated, washed, frozen and thawed, platelet concentrates was prepared and optimally diluted for use in the A.P.T.T. test as a source of platelet phospholipid (P.F. 3). The extract contained, in addition to P.F. 3, active heparin neutralizing activity (P.F. 4), which was able to neutralize plasma heparin up to a concentration of approximately 0.8 units/ml plasma. Although these observations are of a preliminary nature, it is felt that the extract can be used to follow the "intrinsic" coagulability of plasma samples from patients receiving therapeutic heparin. Utilizing the A.P.T.T. test system, the determination of coagulability and the neturalization of heparin result from the use of this extract in a single test.

Sickle cell crisis treated by exchange transfusion. Treatment of two patients with heterozygous sickle cell syndrome.

In two patients with severe painful sickle cell crisis and a deteriorating clinical course, recovery coincided with large-scale exchange transfusions (6 liters). The one patient, with sickle cell beta thalassemia, achieved a 90% exchange, calculated on the sickle cell hemoglobin present before and after transfusion. The other patient, with sickle cell hemoglobin Hb A, S, and (Hb) C disease, also achieved an 80% exchange calculated on the level of HbA.S. AND C in samples before and after transfusion.

Haemoglobin G Norfolk: alpha 85 (F6) Asp leads to Asn.

The characterisation of haemoglobin G Norfolk (alpha2 85 Asp leads to Asn 2) is described. This variant has been identified in the heterozygous state in three apparently unrelated English families of which two are resident in England and the other in Canada.

The estimation of haemoglobin A2: is visual assessment reliable?

Haemoglobin A(2) in 11 normal and 42 B thalassaemia minor subjects was estimated by simple visual assessment of the electrophoretogram. The results obtained give rise to doubts as to the reliability of this technique when used to estimate haemoglobin A(2) under normal laboratory conditions.
