background hemolyis of red blood cells is a serious toxic effect commonly found among patients envenomed by hemiscorpius lepturus scorpion. objectives the aim of the present study was to evlaute the efficay of the avaible polyvalent antivneom in preventing this phenomena. materials and methods using a red blood cell fragility test, the anti-hemolytic effectiveness of a new antivenom serum again...
Haemolytic anaemia denotes a state in which there is an increased rate of red cell destruction. It can be classified on the basis of whether the defect is intrinsic to the red cell or extrinsic to the red cell (that is, a problem in the surrounding environment). Intrinsic defects include defects in the red cell membrane, defects in the red cell enzymes, and defects in globin structure and synth...
Abstract Background: Hereditary red cell enzyme disorders are a group of Non-immune/Spherocytic Hemolytic Anemia, although these disorders are rare and they have not public health problems, the detection of these defects could help to physician in treatment and differential diagnosis. This study evaluated 5 enzymopathies in patients with Hereditary Non –immune/Spherocytic Hemolyti...
Resveratrol, a polyphenolic-stilbene, has received increased attention in the last decade due to its wide range of biological activities. Beta(β)-thalassemias are inherited red cell disorders, found worldwide, characterized by ineffective erythropoiesis and red cell oxidative damage with reduced survival. We evaluated the effects of low-dose-resveratrol (5 μM) on in vitro human erythroid differ...
The effects of cell age on metabolism in the nucleated red blood cells of rainbow trout (Oncorhynchus mykiss) were examined. Red blood cells were separated according to age using fixed-angle centrifugation. The mean erythrocyte haemoglobin concentration in old red blood cells was found to be 120 % of that in young red blood cells. In young red blood cells, the activities of the mitochondrial en...
We have developed a computer software package for Macintosh to simulate the metabolism and hemoglobin binding affinity of human red blood cell. The model is capable of simulating hemoglobin binding of ligands, metabolite concentrations, and metabolic fluxes at physiological steady state and in response to extracellular parameter variations, such as pH, osmolarity, glucose, and adenine concentra...
Background & Aims: The purpose of this study was to survey red blood cell distribution width after experimentally induced pulmonary embolism in rabbit. Due to oxygen transfer performance of red blood cells, the survey of their special forms and passable widths through the vessels in many diseases is vital. One of these diseases is pulmonary embolism in which red blood cell distribution wid...
Red blood cell glucose metabolism was investigated in a male patient with de novo trisomy lOp. According to previous evidence. when assigning hexokinase gene locus in the 1 Op1 1 pter region, a triplex dosage effect of hexokinase activity (HK) was found. while all the other erythrocyte glycolytic enzymes were in the normal values range. Red blood cell glucose utilization was 2.87 zmole/ hr/mi R...
In sickle cell anemia (SCA), inflammatory (i.e., intravascular sickling and transient vasoocclusive) events result in chronic endothelial activation. In addition to sickling behavior, sickle (SS) red blood cells exhibit abnormal interaction with the vascular endothelium, which is considered to have an important role in initiation of vasoocclusion. Upregulation of endothelial adhesion molecules ...
