Abstract

Peripheral blood, bone marrow and/or lymph nodes of 77 patients with T- and B-ALLs/lymphomas were characterized for their surface membrane marker profiles using flow cytometry and fluorescence microscopy. Purine metabolism enzyme activities were compared with membrane immunophenotypes. T and B-ALLs/lymphomas subtypes were defined by the expression of surface membrane antigens detected by the monoclonal antibodies. Based on immunophenotyping we found the following characteristic marker profiles: in T-ALL-CD7, CD2, CD1, CD5, CD3, CD4, CD8, CD38, CD71; in T-NHL-CD7,CD2,CD3,CD4,CD5,CD6; in pre-B ALL-CD10, CD19, CD24, HLA-DR, CD34, in B-ALL-CD19, CD20, CD24, HLA-DR, SmIg with kappa or lamda light chains; in B-ALL-weak SmIg, kappa or lambda, CD19, CD20, CD24, CD5, HLA-DR; in B-NHL-CD19, CD20, CD22, CD24, CD5, more intensive SmIg, kappa or lambda. The cells of leukemic cases tended to have more immature phenotypes than those of lymphoma cases. Analysis of purine metabolism enzyme activities showed that there was a correlation between the values of adenosine deaminase (ADA) and purine nucleoside (PNP) and various types of T- and B-ALLs/lymphomas. ADA levels in B-NHL and B-CLL were lower than those in normal cells, while ADA level in T-...Continue Reading

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.
