| plasma kallikrein | <protein> A plasma serine protease with an apple domain. (18 Nov 1997) |
|---|---|
| plasma labile factor | <chemical> Heat- and storage-labile plasma glycoprotein which accelerates the conversion of prothrombin to thrombin in blood coagulation. Factor v accomplishes this by forming a complex with factor xa, phospholipid, and calcium (prothrombinase complex). Deficiency of factor v leads to owren's disease. Chemical name: Blood-coagulation factor V (12 Dec 1998) |
| plasma layer | The layer of the bloodstream in the capillary vessels, next to the wall of the vessel, that flows slowly and transports the white blood cells along the layer wall, while in the centre the flow is rapid and transports the red blood cells. Synonym: plasma layer, Poiseuille's space, sluggish layer. (05 Mar 2000) |
| plasma marinum | Sea water diluted to make it isotonic with plasma. (05 Mar 2000) |
| plasma membrane | <cell biology> The external, limiting lipid bilayer membrane of cells. (31 Dec 1997) |
| plasma oscillations | <radiobiology> Class of electrostatic oscillations which occur at/near the plasma frequency and involve oscillations in the plasma charge density. Also known as Langmuir Oscillations, In Stix's _Waves in Plasmas_ these are called Langmuir-Tonks Plasma Oscillations. (09 Oct 1997) |
| plasma protein | <haematology> One of the hundreds of different proteins present in blood plasma, including carrier proteins (such albumin, transferrin and haptoglobin), fibrinogen and other coagulation factors, complement components, immunoglobulins, enzyme inhibitors, precursors of substances such as angiotension and bradykinin and many other types of proteins. (14 Oct 1997) |
| plasma proteins | Dissolved protein's (more than 100) of blood plasma, mainly albumins and globulins (normally 6 to 8 g/100 ml); they hold fluid in blood vessels by osmosis and include antibodies and blood-clotting protein's. Synonym: serum proteins. (05 Mar 2000) |
| plasma scalpel | A scalpel that uses a fine high-temperature gas jet, instead of a blade, for cutting. (05 Mar 2000) |
| plasma stain | <technique> Plasmatic stainplasmic stain, a stain whose principal affinity is for the cytoplasm of cells. (05 Mar 2000) |
| plasma substitute | A solution of a substance (e.g., dextran) used for transfusion in haemorrhage or shock as a substitute for plasma. Synonym: plasma expander. (05 Mar 2000) |
| plasma substitutes | Any liquid used to replace blood plasma, usually a saline solution, often with serum albumins, dextrans or other preparations. These substances do not enhance the oxygen- carrying capacity of blood, but merely replace the volume. They are also used to treat dehydration. (12 Dec 1998) |
| plasma therapy | Treatment with plasma. (05 Mar 2000) |
| plasma thromboplastin antecedent | <chemical> Stable blood coagulation factor involved in the intrinsic pathway. The activated form xia activates factor ix to ixa. Deficiency of factor xi is often called haemophilia c. Chemical name: Blood-coagulation factor XI (12 Dec 1998) |
| plasma thromboplastin component | <chemical> Storage-stable blood coagulation factor acting in the intrinsic pathway. Its activated form, ixa, forms a complex with factor viii and calcium on platelet factor 3 to activate factor x to xa. Deficiency of factor ix results in christmas disease (haemophilia b). Chemical name: Blood-coagulation factor IX (12 Dec 1998) |
