Cell suspensions from draining lymph nodes of immune and nonimmune rats were reacted in vitro with (125)I-labeled antigens. In light microscopic radioautographs of smears, 17% of the immunized cells were tagged by specific antigen; 2.0% of control cells were positive. In electron microscopic radioautographs, 90% of the labeled elements from immune donors were lymphocytes, blast and plasma cells...
Tiazofurin (2-/3-i>-ribofuranosylthiazole-4-carboxamide, NSC 286193), a selective inhibitor of the activity of IMP dehydrogenase (EC 1.1.1.205), the rate-limiting enzyme of de novo GTP biosynthesis, provided in end stage leukemic patients a rapid decrease of IMP dehydrogenase activity and GTP concentration in the blast cells and a subsequent decline in blast cell count. Sixteen consecutive pati...
Due to recent involvement in military conflicts, and an increase in the use of explosives, there has been an escalation in the incidence of blast-induced traumatic brain injury (bTBI) among US military personnel. Having a better understanding of the cellular and molecular cascade of events in bTBI is prerequisite for the development of an effective therapy that currently is unavailable. The pre...
Mastitis is one of the most serious and costly diseases affecting dairy cattle production. In the present study, effects of a lactoferrin gene polymorphism (intron 6) on milk somatic cell count (SCC) and subclinical mastitis was investigated in 121 Holstein dairy cattle. Two alleles of A and B and two genotypes of AA and AB were found in an EcoRI recognized single nucleotide polymorphism in int...
Normal mouse marrow cells were stimulated by stem cell factor (SCF) to form dispersed or multicentric blast colonies containing progenitor cells committed to various hematopoietic lineages. Combination of the eosinophil-specific regulator interleukin 5 with SCF increased the frequency of colonies containing eosinophil-committed progenitor cells with multicentric but not dispersed blast colonies...
The blast progenitors in acute myelogenous leukemia grow in response to hematopoietic growth factors (HGFs), and their sensitivity to antileukemic drugs is influenced by HGFs. We report the effects of stem cell factor (SCF) on the growth and sensitivity to 1-beta-D-arabinofuranosylcytosine (Ara-C) of blast progenitors in acute myelogenous leukemia. SCF stimulated both colony formation and self-...
70-year old woman was admitted with a diagnosis of pyelonephritis. The physical examination showed her to be lethargic and febrile (39°C). There was no liver or spleen enlargement. Laboratory findings were as follows: white blood cell count: 25310, hemoglobin level: 11.2 g/dL, platelet count: 41310/L, lacticodehydrogenase level: 4,100 IU/L (normal value < 350); erythrocyte sedimentation rate: 9...
Background: Human embryonic stem cells (hESCs) are capable of self-renewal and large-scale expansion. They also have the capacity to differentiate into a variety of cell types including liver, cardiac and neuron cells. However, it is not yet clear whether hESCs can differentiate to hemangioblasts under in-vitro conditions. Hemangioblasts are bipotential progenitors that can generate hematopoiet...
In cultures of spleen cells from normal mice, recombinant human granulocyte colony-stimulating factor (G-CSF) supported the formation of multipotential blast cell colonies. Serial replating of the blast cell colonies in the presence of G-CSF, however, failed to demonstrate any direct effect of G-CSF on murine multipotential progenitors. We therefore examined the effects of G-CSF in combination ...
Juvenile myelomonocytic leukemia is a rare myeloproliferative disease in young children. While hematopoietic stem cell transplantation remains the only curative therapeutic option for most patients, children with juvenile myelomonocytic leukemia increasingly receive novel agents in phase I-II clinical trials as pre-transplant therapy or therapy for relapse after transplantation. However, respon...
