The red blood cell in vascular occlusion.
Red blood cells (RBC) have unique flow-affecting properties--namely, aggregability, deformability and adherence to endothelial cells (EC)--which play major roles in blood flow. Under normal flow-induced shear stress RBC are dispersed, their adherence to EC is insignificant, and they are sufficiently deformable to enable tissue perfusion. However, in pathological conditions that are associated w...
متن کاملVascular effects of the red blood cell storage lesion.
Transfusion of RBCs is often clinically necessary--and life-saving--for anemic patients. RBCs can be stored for up to 42 days between the time of donation and the time of transfusion. For many years, investigators have studied the biochemical changes that occur in RBCs stored before transfusion (the RBC "storage lesion"). More recently, clinical studies have suggested that RBC units stored for ...
متن کاملVASCULAR ACCESS FOR HEMODIALYSIS: OUR EXPERIENCE WITH 3337 CASES
Over a seven year period from 1982 to 1989,3337 conduits were created in 3137 patients with end stage renal disease (ESRD) as access for chronic dialysis. These included 2690 side-to-side arteriovenous fistulae (A VF), 168 end-to-side A VFs, 10 autogenous vein grafts, 51 homogenous frozen vein grafts, 109 polytetrafluoroethylene (PTFE) grafts, 209 emergency external arteriovenous shunts, t...
متن کاملEffect of Thyroid Dysfunctions on Blood Cell Count and Red Blood Cell Indice
Abstract Background Thyroid hormones have a crucial role in metabolism and proliferation of blood cells. Thyroid dysfunction induces different effects on blood cells such as anemia, erythrocytosis leukopenia, thrombocytopenia, and in rare cases causes’ pancytopenia. It also alter RBC indices include MCV, MCH, MCHC and RDW. Thus this study attempted to evaluate effect of hypo & hyperthyroi...
متن کاملRed cell exchange in sickle cell disease.
Red cell exchange transfusions remain an effective but possibly underutilized therapy in the acute and chronic treatment of sickle cell disease. In sickle cell disease, increased blood viscosity can cause complications when the hemoglobin exceeds 10 g/dL even if this is due to simple transfusion. Red cell exchange can provide needed oxygen carrying capacity while reducing the overall viscosity ...
