| blood motes | Small refractive particles in the circulating blood, probably lipid material associated with fragmented stroma from red blood cells. Synonym: blood dust, blood motes, dust corpuscles. Origin: haemo-+ G. Konis, dust (05 Mar 2000) |
|---|---|
| blood patch, epidural | The injection of autologous blood into the epidural space either as a prophylactic treatment immediately following an epidural puncture or for treatment of headache as a result of an epidural puncture. (12 Dec 1998) |
| blood pH | PH of arterial blood; normal is 7.4 (normal range 7.36-7.44). (05 Mar 2000) |
| blood physiology | Observable characteristics of blood activities and functions, such as blood groups, coagulation processes, etc. (12 Dec 1998) |
| blood plasma | <haematology> Acellular fluid in which blood cells are suspended. Serum obtained by defibrinating plasma (plasma derived serum) lacks platelet released factors and is less suitable to support the growth of cells in culture. (13 Oct 1997) |
| blood plasma fractions | Portions of the blood plasma as separated by electrophoresis or other technique. (05 Mar 2000) |
| blood plastid | Any basic, morphologic unit in the biologic composition of blood, e.g., an erythrocyte. (05 Mar 2000) |
| blood platelets | Non-nucleated disk-shaped cells formed in the megakaryocyte and found in the blood of all mammals. They are mainly involved in blood coagulation. (12 Dec 1998) |
| blood poisoning | See: septicaemia, pyaemia. (05 Mar 2000) |
| blood pool imaging | Nuclear medicine study using a radionuclide that is confined to the vascular compartment. (05 Mar 2000) |
| blood porphyrin level | A test which is used to measure red blood cell porphyrin levels. Porphyrins are pigments found in both animal and plant life. This test is useful in evaluating any number of porphyrin disorders (involving the various porphyrins) of red blood cells. Increased levels of coproporphyrins can indicate congenital erythropoietic porphyria or sideroblastic anaemia. Increased protoporphyrins may be seen in infection, thalassaemia, sideroblastic anaemia, iron deficient anaemia, increased erythropoiesis and lead poisoning. Increased uroporphyrins may indicate congenital erythropoietic porphyria or erythropoietic protoporphyria. (27 Sep 1997) |
| blood products | Biopharmaceutical products purified from human blood, such as the blood clotting factor VIII used to treat haemophiliacs. (Recombinant factor VIII is also on the market.) The term also refers to biopharmaceuticals that act on blood or the cells that make blood. These products are often produced by the cells themselves, but in such tiny amounts that extracting them from blood is impractical, and so they are genetically engineered. (14 Nov 1997) |
| blood protein electrophoresis | Electrophoresis applied to blood proteins. (12 Dec 1998) |
| blood proteins | The hundreds of different proteins present in blood plasma, including carrier proteins (such as serum albumin, transferrin, and haptoglobins), fibrinogen and other blood coagulation factors, complement components, immunoglobulins, enzyme inhibitors, precursors of substances such as the angiotensins and bradykinin, and many other types of proteins. (12 Dec 1998) |
| blood puzzles | Foreign bodies or deformed blood cells that may be misinterpreted as infectious agents (e.g., bacteria, fungi) in stained films as a result of similarities in morphology and staining properties. (05 Mar 2000) |
