plasma protein


Also found in: Dictionary, Thesaurus, Acronyms, Encyclopedia, Wikipedia.

plasma protein

albumin, fibrinogen, prothrombin, and the gamma globulins, which constitute 6% to 7% of the blood plasma. Proteins maintain osmotic pressure, increase blood viscosity, and help maintain blood pressure. All the plasma proteins except the gamma globulins are synthesized in the liver. See also antibody, serum.

plasma protein

A protein present in blood plasma, such as albumin or globulin.

plasma

the fluid portion of the blood in which corpuscles are suspended. Plasma is to be distinguished from serum, which is plasma from which the fibrinogen has been separated in the process of clotting.

plasma bound
many electrolytes exist in plasma in a form in which they are bound to protein which reduces their lability and liability to loss in the urine, e.g. protein-bound iodine.

plasma cell myeloma
see multiple myeloma.
plasma cell pododermatitis
a nonpainful swelling with ulceration and exuberant granulation tissue on the footpads of cats. The cause is unknown but believed to be immunological.

plasma clearing factor
a lipoprotein lipase which lipolyses the triglyceride in the chylomicrons of the plasma and hence clears it of cloudiness.
plasma exchange
the removal of plasma from withdrawn blood (plasmapheresis) and retransfusion of the formed elements and type-specific fresh-frozen plasma into the donor; done for removal of circulating antibodies or abnormal plasma components.
plasma expanders
see plasma volume expander.
fresh-frozen plasma
prepared from whole blood; a source of coagulation factors.
plasma protein
the heterologous group of proteins in circulating blood that includes albumin, lipoproteins, glycoproteins, transcortin, haptoglobin, ceruloplasmin, cholinesterase, α2-macroglobulin, erythropoietin, transferrin, hemopexin, fibrinogen, plasminogen and the immunoglobulins (γ-globulins).
plasma protein:fibrinogen (PP:F) ratio
an indicator of significant changes in fibrinogen levels, taking into account dehydration.
plasma substitute
a fluid suitable for use as a replacement for plasma in the animal body. Usually a solution of gelatin or dextran.
therapeutic plasma concentration
a therapy-response relationship determined only by experiment; the plasma level which is matched by the desired therapeutic response.
plasma thromboplastin antecedent
clotting factor XI; see plasma thromboplastin antecedent.
plasma turbidity test
a qualitative test for fat absorption, performed by comparing the turbidity of plasma before and 2, 3 and 4 hours after the oral administration of fats, usually vegetable oil. Results are greatly influenced by delays in gastric emptying, so normally this test can only be relied upon to rule out malabsorption or maldigestion when evidence of absorption is found.
plasma volume
the estimation of plasma volume is essential to a complete knowledge of a patient's fluid status. The common technique is by the intravenous injection of a known amount of a dye such as Evans blue and the subsequent measurement of the dilution that it has undergone in a set time period.
