...Xiaoye Sun; Yifeng Cai; Hui Ni; Hui Cong Introduction: The aims of this study were to observe the therapeutic effect of platelet (PLT) transfusion and to analyze influencing factors for the sake of providing useful clues for improving the efficacy of PLT transfusion. Methods: Included in this study...

..., there is concern that HIF-PHI might be prone to iron deficiency and that thrombosis might be induced by increased platelet and transferrin levels due to this iron deficiency. Methods: Relationship of iron-related factors with platelet count (PLT) and total iron-binding capacity (TIBC; which reflects...

...Tal Sadeh-Vered; Nurit Rosenberg; Iris Morag; Asaf A. Berg; Gili Kenet; Tzipora Strauss Background: We evaluated the effect of surfactant on platelet function as a potential contributing mechanism to the pathogenesis of pulmonary hemorrhage (PHEM) in term and preterm infants. Methods: Cord blood...

...J.F. Stoltz; A. Nicolas The authors attempted to evaluate different reagents in order to quantify the amino groups of the platelet membrane. The study was carried out by the action of different aldehydes and acid anhydrides. The use of 2,4,6-trinitrobenzenesulfonic acid made possible an approach...

... normalized after vitamin B 12 treatment. After treatment, platelet size changed toward a smaller diameter, but platelet size, however, was not significantly different from the normal platelet size distribution. 15 03 1978 25 05 1978 3 3 2009 © 1979 S. Karger AG, Basel 1979 Copyright...

...Kiyoh Tanishima; Takasumi Matsuki; Nahoko Fukuda; Masazumi Takeshita; Yoshimasa Yoneyama Normal levels of NADH-cytochrome b 5 reductase activity in platelets, lymphocytes and granulocytes were determined. The homogenate of each cell was treated with Triton X-100 after incubation with lipoprotein...

...Stephen J. Proctor; Terry F. Davies; Alan Oxley; Peter Jones; Alan Heath The effect of 1 mg of intravenous glucagon on platelet aggregation has been investigated in 12 normal subjects pre-treated with salicylate. All subjects demonstrated the expected inhibition of collagen-induced secondary...

...A. Berrebi; E. Vorst; M. Shtalrid; P. Resnitzky; E. Nir Platelet aggregation induced in vitro with ADP, adrenalin and ristocetin was tested in 7 patients with megakaryoblastic leukemia (MKL). All patients had normal or high platelet counts and presented with hemorrhagic diathesis including purpura...

...Lennart Andrén; Hans Wadenvik; Jack Kutti; Lennart Hansson Severe stress, with increased secretion of adrenaline, is likely to cause platelet activation. The aim of the present study was to investigate if moderate stress, which usually is not accompanied by adrenaline secretion, could induce...

...M.S. El-Alfy; M.N. El-Tayeb The spleen acts as a major site of clearance of antibody-coated platelets from circulation in immune thrombocytopenia (ITP). Splenectomy carries a high cure rate. The biological effect of a single therapeutic dose of ultrasound directed transthoracically to the spleen...

...Yulia Kaluzhny; Katya Ravid Platelets are anucleate cells that fragment from mature megakaryocytes and play an essential role in thrombosis and hemostasis. Platelets are among the first cell types to be recruited to an injured blood vessel, assisting in endothelial repair. Platelet hyperactivation...
