    摘要: A first aspect of the present invention is a blood platelet preparation comprising blood platelets, an adenylate cyclase stimulator, a phosphodiesterase inhibitor, a thrombin inhibitor, and a plasmin inhibitor. A second aspect of the present invention is a plasma-free platelet storage medium containing dextrose, sodium citrate, sodium bicarbonate, and a platelet activation inhibitor, with a preferred platelet activation inhibitor comprising an adenylate cyclase stimulator in combination with a phosphodiesterase inhibitor. A third aspect of the present invention is a process for producing a plasma-free platelet preparation comprising producing platelet-rich plasma (PRP) from whole blood, adding a platelet activation inhibitor thereto, centrifuging the PRP to deposit the platelets on the bottom of the centrifuge container, removing the platelet-free plasma supernatant therefrom and adding a plasma-free liquid platelet storage medium thereto. A preferred platelet activation inhibitor for the process comprises an adenylate cyclase stimulator in combination with a phosphodiesterase inhibitor.A preferred adenylate cyclase stimulator is Prostaglandin El, a preferred phosphodiesterase inhibitor is Theophylline, a preferred plasmin inhibitor is Aprotinin, and a preferred thrombin inhibitor is N-(2-naphthylsulfonylglycyl)-D,L-amidinophenylalaninpiperidide.

    摘要: Fixed-dried red blood cells (RBCs), and processes for preparing the same are disclosed. The red blood cells, upon reconstitution with distilled water or appropriate buffer: bind oxygen with native affinities, have partial deformability, present minimal thrombogenicity to platelets, and have oblated blood group antigens. The RBCs are preferably fixed by means of cross-linkers with aldehyde functions such as paraformaldehyde or glutaraldehyde either alone or in combination. Native oxygen kinetics are achieved by preparing the red blood cells with 1,6-diphosphofructose. Blood group antigens and chemical functions that render the lyophilized RBCs thrombogenic are occluded by chemically attaching polyoxyethylene glycol polymers to the surface membrane of the red blood cells. The cross-linked red blood cells are preferably died by lyophilization.

    摘要: A method for inactivating microbiological contaminants in a human blood platelet preparation is disclosed. The method comprises, first, providing blood platelets, particularly human blood platelets, suspected of being contaminated with microorganisms. The platelets are then contacted to a fixative for a time sufficient to fix the platelets. After fixing, the platelets are preferably washed and dried to produce fixed-dried platelets. The step of contacting the platelets to a fixative is carried out for a time sufficient to kill some or all the of the contaminating microorganisms.
