midface bones are an unusual site for primary presentation and relapse in acute lymphoblastic leukemia. herein, we describe a case of acute pre b cell lymphoblastic leukemia with leukemic infiltration of maxilla and bone marrow involvement. at the time of relapse, the patient presented again with maxilla involvement and the phenotype changed to biphenotypic lymphoblastic leukemia. our case sugg...

Although leukocytes from all 13 acute lymphoblastic ieu kemia patients examined had high terminal deoxynucleoti dyl transferase (terminal transferase) activity (20 to 100 units/mg of cellular DNA, where 1 unit equals 1 nmole of nucleotide polymenized in 1 hr) and those from 21 acute myelocytic leukemia patients had low terminal transferase activity (0.2 to 2 units/mg of cellular DNA), the bone ...

We hypothesized that the sister chromatid exchanges assay in acute leukemia long-term survivors may detect: (a) long-term effects of combined chemo- and radiotherapy; and possibly (b) those individuals with inherently deficient DNA repair. Accordingly, we determined the sister chromatid exchanges frequency in 26 blood specimens from 24 acute leukemia long-term survivors (patients) and 14 blood ...

Ultrastructural histochemical evaluation of the surface of normal human blood and bone marrow cells exposed to the pyroantimonate-osmium (PAO) reaction indicated the selective binding of pyroantimonate to certain cations (calcium, magnesium, and possibly sodium) associated with the plasma membrane of neutrophilic leukocytes and their developmental forms. Other leukocytes and their precursors di...

With a newly developed turbidometric method, concana valin A was shown to agglutinate normal lymphocytes, lym phoma cells, and leukemic cells from chronic lymphocytic leukemia and from acute myelocytic and lymphocytic leuke mia. However, there was a marked difference in the kinetics of this agglutination process. Leukemic blast cells and cells from a patient with convoluted lymphoma agglutinate...

acute myeloblastic leukemia is one of the important malignancies in children. for better managing the prognosis of this disease, there should be enough information about common features of this malignancy. the aim of this study was to evaluate these common features in children with acute myeloblastic leukemia. a total of 104 eligible children less than 15-year-old have been referred from 2007-2...

The activity of thymidylate synthase (TS) purified in our laboratory from Lactobacillus leichmannii was inhibited by pergularinine (PGL) and tylophorinidine (TPD) and deoxytubulosine (DTB) isolated from the Indian medicinal plants Pergularia pallida and Alangium lamarckii respectively. Cytotoxicity studies showed that cell growth of L. leichmannii was inhibited (IC50 = 40-45 microM) by all the ...
