Medium conditioned in the presence of human HUT-102 T-cell line cells contains activities stimulating human mixed (colony-forming unit, erythroid, granulocyte, macrophage, megakaryocyte) and erythroid (burst-forming unit, erythroid) colony formation in methylcellulose in vitro and granulocyte colony formation in diffusion chambers in mice. The stimulatory effect of HUT-102-conditioned medium on...

This study evaluates the effect of recombinant human stem cell factor (SCF) on the in vitro response of human bone marrow progenitor cells to irradiation. Light density nonadherent mononuclear cells were isolated from human bone marrow and resuspended in either semisolid culture or liquid culture with or without 100 ng/ml SCF. After 24 h in culture, cells were irradiated and assessed for surviv...

OBJECTIVE To determine the efficacy of 2.5% and 1.25% Povidone-Iodine solution for Ophthalmia neonatorum prophylaxis. STUDY DESIGN Interventional study. PLACE AND DURATION OF STUDY Eye Department, Combined Military Hospital, Sargodha, from May to November 2014. METHODOLOGY Atotal of 200 eyes of 100 newborn babies were enrolled and divided into two groups of 100 right eyes and 100 left eye...

Antibiotics are added to semen extenders to take care of heavy microbial load, however, their continuous use poses a constant threat of developing antibiotic resistance by the common microbes present in the semen. Our hypothesis was that natural honey, having antibacterial activity and rich in fructose could replace the use of antibiotics and fructose in the semen extender. Twenty-four ejaculat...

conclusions caffeic acid treatment reduced bacterial growth and resulted in a decreased number of colony formation. the simultaneous effect of caffeic acid and laser at three time courses showed a synergic effect in reducing colony formation compared to the control and caffeic acid, and laser alone. objectives the aim of this study was to investigate the effect of caffeic acid and low-power las...

To evaluate whether the response of hematopoietic cells to interleukin-17 (IL-17) depends on the tissue microenvironment in which hematopoiesis occurs, the influence of recombinant mouse IL-17 on spleen hematopoietic cells and cytokine release was assessed in normal mice in vitro and in vivo. In vitro, IL-17 did not significantly affect the growth of granulocyte-macrophage (CFU-GM) and erythroi...

We investigated the in vitro effects of 4-hydroperoxycyclophosphamide (4-HC) on human hemopoietic stem cells. Marrow cells were exposed to 4-HC and then assayed for mixed (CFU-GEMM), erythroid (BFU-E), megakaryocyte (CFU-M), and granulocyte-macrophage (CFU-GM) colony forming cells. We found that highly proliferative colony forming cells, especially CFU-GEMM and BFU-E, were relatively spared by ...

Transcription factor GATA-1 is essential for the development of the erythroid lineage. To ascertain whether strict control of GATA-1 expression level is necessary for achieving proper erythropoiesis, we established transgenic mouse lines expressing green fluorescent protein (GFP) under the control of the GATA-1 gene hematopoietic regulatory domain. We examined the GATA-1 expression level by exp...
