Ventricular assist devices (VADs) have already helped many patients with heart failure but have the potential to assist more patients if current problems with blood damage (hemolysis, platelet activation, thrombosis and emboli, and destruction of the von Willebrand factor (vWf)) can be eliminated. A step towards this goal is better understanding of the relationships between shear stress, exposu...

BACKGROUND Management of hemolysis in the setting of suspected device thrombosis in continuous-flow left ventricular assist device patients varies widely, ranging from watchful waiting with intensified antithrombotic therapy to early surgical device exchange. The aim of this study was to compare the outcomes of hemolysis events treated with surgical interventions versus medical management alone...

Cooper, Louis Z. (New England Center Hospital, Boston, Mass.), Morton A. Madoff, and Louis Weinstein. Hemolysis of rabbit erythrocytes by purified staphylococcal alpha-toxin: I. Kinetics of the lytic reaction. J. Bacteriol. 87:127-135. 1964.-The hemolytic activity of purified staphylococcal alpha-lysin was found to be directly proportional to toxin concentration and inversely related to the log...

BACKGROUND Immune thrombocytopenic purpura and secondary thrombocytopenia patients treated with Rh(o)(D) immune globulin intravenous (human; anti-D IGIV) have experienced acute hemolysis, which is inconsistent with the typical presentation of extravascular hemolysis -- the presumed mechanism of action of anti-D IGIV. Although the mechanism of anti-D-IGIV-associated acute hemolysis has not been ...

Heterogeneity within ghosts prepared from stored erythrocytes was studied by multichannel particle analysis of size distributions of reconstituted ghosts. On restoration of isotonicity of hemolysates from fresh erythrocytes, ghosts were smaller than the corresponding red cells. After subsequent incubation for 15 mm, they swelled to a final stable volume. The hemolysis of stored erythrocytes and...

This report describes the development of hemolysis in eighteen glucose-6-phosphate dehydrogenase deficient patients treated for Plasmodium vivax malaria with chloroquine and primaquine. The most frequent findings accompanying hemolysis were fever and leukocytosis, in addition to anemia requiring red blood cell transfusion, and development of acute renal failure. Hemolysis in patients using prim...

A hemolytic transfusion reaction (HTR) is the accelerated clearance or lysis of transfused red cells because of immunologic incompatibility. Although they may at times have similar clinical presentations, HTR is distinguished from autoimmune hemolysis or nonimmune causes of shortened survival of transfused red cells. HTR may occur when antigen-positive red cells are transfused to a patient with...

Abstract Objectives Automated sample delivery and laboratory acceptance systems (PTAS) may influence the hemolysis rate of blood samples due to g-forces, abrupt acceleration, rapid deceleration. However, quantitative data regarding in PTAS is limited. To fill this void, effect a pneumatic tube combination with an system on was investigated study. Methods Lithium heparin plasma tubes were transp...

it is well known that there are lower erytrocyte count and hernoglobin(Hb) value in the sportsmen than sedentary peop]e. It calied sportsanemia. Developrnent of anemia a sportsman may depend on bleeding from urinary gastrointestinal tracts hemolysis during exercise some other factors. We opinion rewiev about these two sportsanernia reasons(bleeding hemolysis) be useful for investigators who stu...
