Chemiluminescence properties of human, canine and rat polymorphonuclear cells.

Human as well as canine and rat polymorphonuclear cells (PMN) were separated from whole blood by centrifugation. Two-step discontinuous Percoll gradients with distinct different densities were used. The chemiluminescence properties of the isolated PMN and of phagocytes in small quantities of whole blood were compared in luminol-enhanced assays after stimulation with various agents: non-opsonized zymosan (3.

On the biocompatibility of IBM 2997 continuous flow plateletapheresis.

During the procedure of centrifugation cytapheresis donors occasionally experience adverse clinical reactions. We evaluated the possibility of whether activation of granulocytes and their subsequent release reactions, which may have been triggered by this extracorporeal circuit, were responsible for these adverse effects. Six blood samples were obtained during various set intervals during plateletapheresis.

Evaluation of granulocyte-releasing products and chemiluminescence during cytapheresis.

During the procedures of centrifugation leukapheresis and plateletpheresis, donors occasionally experience adverse clinical reactions. The possibility of whether the activation of granulocytes and the subsequent release reactions, which may have been triggered by this extracorporeal circuit, were responsible for these adverse effects was evaluated. Six blood samples were obtained at set intervals during cytapheresis.

Efficacy and safety of a polyester leukocyte removal filter for whole blood and red cell concentrate filtration.

Patients receiving multiple whole blood transfusions often experience adverse clinical symptoms caused by leukocytes. In the present study, the efficacy and safety of a polyester filter for leukocytes (Sepacell R-500) was evaluated. Donor units of whole blood and red cell concentrate stored for varying lengths of time were filtered.

Separation and chemiluminescence properties of human, canine and rat polymorphonuclear cells.

Human as well as canine and rat polymorphonuclear cells (PMN) were separated from whole blood by centrifugation. Two-step discontinuous Percoll gradients with distinct densities were used. The purity of the preparations was 99.
