| cell fractionation | <technique> Strictly this should mean the separation of homogeneous sets from a heterogeneous population of cells (by a method such as flow cytometry). The term is more frequently used to mean subcellular fractionation i.e. The separation of different parts of the cell by differential centrifugation, to give nuclear, mitochondrial, microsomal and soluble fractions. (26 Mar 1998) |

| dose fractionation | Adminstration of the total dose of radiation (radiation dosage) in parts, at timed intervals. (12 Dec 1998) |
| fractionation | A term used to describe any method for separating and purifying biological molecules. See: cell fractionation. (18 Nov 1997) |
| sea foam | 1. Foam of sea water. 2. <chemical> Meerschaum. Synonym: sea froth. Source: Websters Dictionary (01 Mar 1998) |
| human fibrin foam | A dry artificial sponge of human fibrin prepared by clotting with thrombin a foam of a solution of human fibrinogen; the clotted foam is dried from the frozen state and heated; used as a topical anticoagulant. (05 Mar 2000) |
| fibrin foam | <chemical> A dry artificial sterile sponge of fibrin prepared by clotting with thrombin a foam or solution of fibrinogen. It is used in conjunction with thrombin as a haemostatic in surgery at sites where bleeding cannot be controlled by more common methods. Pharmacological action: haemostatics, tissue adhesives. (12 Dec 1998) |
| foam | 1. To gather foam; to froth; as, the billows foam. "He foameth, and gnasheth with his teeth." (Mark ix. 18) 2. To form foam, or become filled with foam; said of a steam boiler when the water is unduly agitated and frothy, as because of chemical action. Origin: AS. F?man. See Foam, n.

| foam cell | <pathology> Lipid laden macrophages and, to a lesser extent smooth muscle cells, found in fatty streaks on the arterial wall. (18 Nov 1997) |
| foam cells | Lipid-laden macrophages originating from monocytes or from smooth muscle cells. (12 Dec 1998) |
| foam stability test | A test for foetal pulmonary maturity, determined by the ability of pulmonary surfactant in amniotic fluid to generate stable foam in the presence of ethanol after mechanical agitation. Synonym: shake test. (05 Mar 2000) |
