Deoxygenation-induced changes in sickle cell-sickle cell adhesion.
The tendency for sickle cells to adhere to each other is increased in oxygenated sickle blood in parallel with cell density. The increased adherence of these cells occurred despite their reduced deformability and diminished ability to form rouleaux. Using a method developed in our laboratory, we measured the yield stress: a sensitive index of cell-cell adhesion of deoxygenated suspensions of si...

متن کاملIntracardiac Thrombosis in Sickle Cell Disease
In patients with sickle cell disease, thrombotic microangiopathy is a rare complication. Also in sickle cell disease, intracardiac thrombus formation without structural heart diseases or atrial arrhythmias is a rare phenomenon. We herein describe a 22-year-old woman, who was a known case of sickle cell-βthalassemia, had a history of recent missed abortion, and was admitted with a vaso-occlusive...
متن کاملSickle-cell hemoglobin: fall in osmotic pressure upon deoxygenation.
Macromolecules such as hemoglobin exert both kinetic and matrix effects on osmotic pressure. The kinetic osmotic pressure of sickle-cell hemoglobin is lost upon deoxygenation at physiological erythrocyte concentrations. The non-kinetic or matrix component of osmotic pressure remains relatively unchanged. Loss of thermal-osmotic activity during deoxygenation occurs throughout a hemoglobin concen...
