Evaluation of median survival patients with acute lymphoblastic leukemia exposed to ionizing radiation by the Chornobyl accident, depending on the aminoacid composition of stromal fibroblasts bone marrow and indicators of myelogram.

Objective: To investigate the aminoacid composition in the stromal fibroblasts of bone marrow and indexes of hemogram in children with acute lymphoblastic leukemias, which exposed to radiation from the Chornobyl accident, for evaluation of the median survival.

Materials And Methods: In the study 54 patients with acute lymphoblastic leukemia, residents of Kyiv, Zhytomyr and Chernihiv regions of Ukraine were involved. Effectiveness of stromal fibroblasts colony forming units of bone marrow and aminoacid composition of fibroblasts were studied.

Effect of RBC concentrate transfusions on serum ferritin content in children with acute leukaemia.

Objective: To study the serum ferritin levels in children with acute leukemia, depending on the number of transfusions of RBC concentrate and period of disease.

Materials And Methods: We studied the red blood count, serum iron and ferritin levels in 54 patients with acute leukemia before chemotherapy, at the time of a standardized treatment protocol, and after transfusions of RBC concentrates.

Results: In the debute of acute leukemia just before treatment lauch the serum ferritin in 81.
