| platelet storage pool deficiency | A group of disorders characterised by a decrease or lack of platelet dense bodies in which the releasable pool of adenine nucleotides and 5ht are normally stored. (12 Dec 1998) |
|---|---|
| platelet thrombosis | Thrombosis due to an abnormal accumulation of platelets. (05 Mar 2000) |
| platelet tissue factor | <haematology> Traditional name for substance in plasma that converts prothrombin to thrombin. Now known not to be a single substance. (See thrombin). (18 Nov 1997) |
| platelet transfusion | The transfer of blood platelets from a donor to a recipient or reinfusion to the donor. (12 Dec 1998) |
| low affinity platelet factor IV | Cytokine, produced from platelet basic protein, that acts as a growth factor. (18 Nov 1997) |
| low platelet count | <haematology> An abnormally low platelet count. Normal platelet counts are 150,000-400,000 per cubic millimetre. Those with low platelet counts may exhibit haematuria, haematemesis, easy bruising, bleeding gums, melena (blood in stools), prolonged menses or nosebleeds. Spontaneous intracranial haemorrhage can occur with platelet counts of 10-15,000 (or less). (27 Sep 1997) |
| allomeric function | The combined function of the several segments of the spinal cord and medulla, communicating with each other by means of the white matter. (05 Mar 2000) |
| aperture function | <microscopy> In a diffraction-limited optical system, the function that determines the relationship between the image and each point in the object. Modifying the aperture function changes the image according to the modified Fourier-filtering (or optical filtration) property of the aperture. (05 Aug 1998) |
| arousal function | The ability of a sensory event to arouse the cortex to vigilance or readiness. (05 Mar 2000) |
| atrial function | The haemodynamic and electrophysiological action of the atria. (12 Dec 1998) |
| atrial function, left | The haemodynamic and electrophysiological action of the left atrium. (12 Dec 1998) |
| atrial function, right | The haemodynamic and electrophysiological action of the right atrium. (12 Dec 1998) |
| atrial transport function | The role of the atria in filling and stretching the ventricles by their presystolic contraction, without which the force of ventricular contraction and hence the cardiac output may significantly decrease. (05 Mar 2000) |
| mapping function | In linkage analysis, a formula that converts the recombination fraction (which is on the probability scale) into map distance (in morgans). (05 Mar 2000) |
| ventricular function | The haemodynamic and electrophysiological action of the ventricles. (12 Dec 1998) |
