[Work on the Haemonetics 30 blood cell separator]. / Neki aspekti rada na separatoru celija krvi tipa Haemonetics 30.

Our experience with cell separator led us to the conclusion that platelet concentration is rather high (6,94 X 10(11)/L), especially in the part of separated blood which contains significant percentage of erythrocytes. A considerable amount of leukocytes (1,6 X 10(10)/L) can be separated as well. It should be mentioned that leukocyte concentrations are significantly higher when Dexan is administered intravenously and Plasmasteril is used. Therapeutic plasmapheresis requires different approach which varies from the usual work with blood donors, since complications can be expected. Appropriate choice of plasma substituents should be made, as well as constant monitoring of electrocardiographic changes in patients.

[Transfusion of leukocytes and platelets in the treatment of acute leukemia]. / Transfuzija leukocita i trombocita u lecenju akutnih leukemija.

Supportive therapy of concentrated leukocytes and platelets has no obvious significance. In the paper authors presented the methods of separation of concentrated leukocytes and platelets, investigation of number and functional abilities of preserved leukocytes and platelets as well as the monitoring of the transfusion effect in the patients with acute myeloblastic leukemia. Special attention was paid to the separation of blood cells by the cell centrifuge with continuous flow. Side effects after leukocytes and platelet transfusion was monitored -- occurence of the sensibilization to the HL-A antigens. For the detection of HL-A antibodies two-stage microlymphocytotoxic test was used for the investigation of patient's serum; for the application of leukocyte and platelet transfusion we used cross-match test between donor's lymphocytes and patient's serum in progressive dilution. In the paper authors discussed the correlation between the appearance of HL-A antibodies and the number of given transfusions.
