The activity of recombinant human growth hormone (rhGH) in enhancing CD34(+) cell mobilization elicited by chemotherapy plus recombinant human granulocyte colony-stimulating factor (rhG-CSF) was evaluated in 16 hard-to-mobilize patients, that is, those achieving a peak of circulating CD34+ cells 10/microL or less, or a collection of CD34(+) cells equal to or less than 2 x 10(6)/kg. Patients who...

Osmotic pumps containing Escherichia coli-derived recombinant human granulocyte colony-stimulating factor (rhG-CSF) were attached to indwelling jugular vein catheters and implanted subcutaneously into Golden Syrian hamsters. Within 3 days, peripheral granulocyte counts had increased greater than 10-fold with a concomitant 4-fold increase in total leukocytes. Microscopic examination of Wright-Gi...

OBJECTIVE To examine the effect of rhG-CSF on allogeneic bone marrow transplantation. PATIENTS AND METHODS One hundred and twenty patients with acute or chronic leukemia received HLA-A.B.DR identical and MLC negative sibling donor allo-BMT. Among them, 58 cases of were treated with recombinant human granulocyte colony-stimulating factor (rhG-CSF), while the other 62 cases of the 120 patients ...

Recombinant human granulocyte colony-stimulating factor (rhG-CSF) enhanced superoxide release and membrane depolarization in parallel in human granulocytes stimulated by the receptor-mediated agonists, N-formyl-methionyl-leucyl-phenylalanine and wheat germ agglutinin, but not by the Ca2+ ionophore ionomycin and phorbol myristate acetate, which bypass the receptors to stimulate the cells. The op...

BACKGROUND AND OBJECTIVE Recombinant human granulocyte colony-stimulating factor (rhG-CSF) is currently used for treatment of various types of neutropenia, treatment of aplastic anemia, mobilization of peripheral blood progenitor cells. However, rhG-CSF is not only a growth factor for the myeloid lineage, but it also acts as a modulator of neutrophil behavior. The aim of the present review arti...

BACKGROUND Human recombinant granulocyte colony-stimulating factor (rhG-CSF), widely used to combat chemotherapy-induced neutropenia, stimulates both in vivo and in vitro intra- and extra-cellular O2- production in human polymorphonuclear cells (PMNs). PATIENTS AND METHODS Twelve patients with solid tumors or acute lymphoblastic leukemia were treated during induced aplasia with rhG-CSF (5 mic...

In this study, we have compared the ability of recombinant human granulocyte colony-stimulating factor (rhG-CSF) alone and the combination of low doses of recombinant rat pegylated stem cell factor (rrSCF-PEG) plus rhG-CSF to mobilize peripheral blood progenitor cells (PBPCs) with long-term engrafting potential. Female recipient irradiated mice were transplanted with PBPCs from male mice that w...

The use of low concentrations of urea, guanidinium chloride or arginine has been reported in the literature to increase protein refolding and yield of active proteins by suppressing aggregate formation. However, no studies have yet examined whether these substances can exert synergistic or cooperative effects when used in combination. In this work, a comparative study was carried out on refoldi...

This study attempts to clarify whether intensity of exercise influences functional sympatholysis during mild rhythmic handgrip exercise (RHG). We measured muscle oxygenation in both exercising and non-exercising muscle in the same arm in 11 subjects using near infrared spectroscopy (NIRS), heart rate, and blood pressure. We used the total labile signal to assess the relative muscle oxygenation ...

Recombinant human gelatin was conjugated with dopamine using carbodiimide as a surface modifier. This dopamine-coupled human gelatin (D-rhG) was characterized by (1)H-nuclear magnetic resonance, mass spectroscopy, and circular dichroism. D-rhG-coated surface properties were analyzed by physicochemical methods. Additionally, cell attachment and growth on the modified surfaces was assessed using ...
