Two separate helper T cell-derived lymphokines, interleukin 3 and granulocyte-macrophage colony-stimulating activity-2, were found to stimulate a broad and similar range of hemopoietic colonies in in vitro soft agar cultures including granulocyte, macrophage, granulocyte-macrophage, megakaryocyte, and mixed megakaryocyte colonies. Both lymphokines were potent stimulators of in vitro megakaryocy...

We studied the effects of alcohol and propranolol on the course of peritonitis in rabbits. Induction of sterile peritonitis with normal saline led to a 50% augmentation of granulocyte adherence in normal rabbits, and a mean cumulative granulocyte count of 27,000/mm(3) in peritoneal exudate by 8 h. Rabbits intoxicated with alcohol at the time of peritonitis induction maintained a granulocyte adh...

Aplastic anemia and myelogenous leukemia are prominent pathologic effects in beagles exposed to continuous, daily, low-dose gamma irradiation. In the present work, granulocyte reserves and related mobilization functions have been sequentially assessed by the endotoxin stress assay during the preclinical and clinical phases of these hemopoietic disorders. Characteristic patterns of granulocyte r...

Compared with hetastarch (HS), the low molecular weight analog pentastarch (PS) has been reported to be equally effective for granulocyte collection by centrifugal leukapheresis, to result in fewer adverse donor reactions (ADR), and to have a more rapid elimination profile. We prospectively compared the granulocyte collection efficiency (GCE), granulocyte yield, and ADR in 72 randomly paired gr...

BACKGROUND Information about the long-term follow-up and safety of granulocyte colony-stimulating factor administration to healthy donors is limited. The aims of this study were to analyze the side effects of granulocyte colony-stimulating factor administration in donors included in a Spanish Registry of hematopoietic stem cell donors and to determine the long-term outcome of these donors. DE...

BACKGROUND Mobilization of hematopoietic stem/progenitor cells from the bone marrow to the peripheral blood by granulocyte colony-stimulating factor is the primary means to acquire stem cell grafts for hematopoietic cell transplantation. Since hematopoietic stem/progenitor cells represent a minority of all blood cells mobilized by granulocyte colony-stimulating factor, the underlying mechanisms...
