Abstract

The authors examined acute leukaemia cells sensitivity to anticancer drugs using 2 short-time methods: 1. Measurement of the inhibition of 3HTdr incorporation during 2 h incubation with cytostatic; 2. Evaluation of the cell viability in short-term (5 days) liquid culture. The 37% decrease in living cells count or in the rate of 3HTdr incorporation has been evaluated as indicating sensitivity to examined drugs. Out of many determinations performed by these use of 2 mentioned methods, those executed simultaneously were compared. Comparable results were obtained to arabinoside-cytosine testing, showing ca. 94% of sensitive cases.In relation to vincristine the 3HTdr incorporation method showed more often - in 82% of cases - sensitivity as compared to only 46% tested in culture method, whereas to daunorubicine more common effect on cultured cells viability (86%) than on tritiated thymidine incorporation (40%) could be observed. These differences remain to be elucidated as to their technical or biological sources. The sensitivity to L-asparaginase was shown only in about the half of cases by both methodes.

Acute Myeloid Leukemia

Acute myeloid leukemia (AML) is a clinically and genetically heterogeneous disease with approximately 20,000 cases per year in the United States. AML also accounts for 15-20% of all childhood acute leukemias, while it is responsible for more than half of the leukemic deaths in these patients. Here is the latest research on this disease.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
