Erythrocytes (RBC) from untrained male Wistar rats and rat glomerular endothelial cells (EC) were used to investigate the effects of acute exercise (speed: 20 m/min, slope: 0, duration: 1 hour) on RBC membrane protein oxidation and adhesion to cultured EC. Experimental animals were divided into juvenile (age 10 weeks) and adult (age 30 weeks) groups for these studies. Immediately following exer...

The vasoocclusive process in patients with sickle cell disease (SCD) is complex and involves interactions among sickle erythrocytes (SS-RBC), vascular endothelium, and plasma and cellular components. The role of neutrophils (PMN) in vasoocclusion has not been examined. Patients with SCD appear to have chronically activated PMN. Because the first step in PMN activation is particle recognition, w...

objective: the two most frequent hypochromic microcytic anemias are β- thalassemia minor (btm) and iron deficiency anemia (ida). several discrimination indices have been proposed to quickly discriminate these similar entities via parameters obtained from automated blood count analyzers. the aim of this study to evaluate the diagnostic reliability of ten discrimination indices in the differentia...

BACKGROUD The aim of the study was to evaluate the effect of early parenteral iron supplementation combined erythropoietin for prevention of anemia in preterm infants. METHODS In total, 96 preterm infants were randomly assigned to 3 groups: a control group receiving standard parenteral nutrition (group 1: n = 31), an iron-supplemented group (group 2: IS, n = 33), and an iron-supplemented comb...

Antistreptolysin O (ASO) titers were determined on 117 human sera with rabbit, human, and sheep red blood cells (RBC) as the indicator system in the ASO tube test. The titers of 65% of the sera were one dilution step higher when a 5% suspension of sheep RBC was used instead of a 5% suspension of rabbit RBC. Titers were one dilution step higher in 42.7% of the sera when a 5% suspension of human ...

Patients with Polythemia vera (PV) have a high incidence of thrombosis (25-75 %). Vascular complications are responsible of retinopathy, renal failure and coronary disease in diabetes mellitus (DM). Retinal Vascular Vein Occlusion (RVO) is a cause of blindness. To evaluate is red blood cell (RBC) abnormalities may be one vascular risk in these disease we studied RBC adhesion to endothelial cell...

Horse blood has a higher tendency to form red blood cell (RBC) aggregates compared with human blood, with this enhanced aggregation previously attributed to differences in plasma factors. Our results confirm this observation and further indicate that washed horse RBC also have a significantly higher aggregation tendency in dextran 70 solutions (i.e., horse RBC have a higher "aggregability"). In...
