| carcinoma, lewis lung | A carcinoma discovered by dr. Margaret r. Lewis of the wistar institute in 1951. This tumour originated spontaneously as a carcinoma of the lung of a c57bl mouse. The tumour does not appear to be grossly haemorrhagic and the majority of the tumour tissue is a semifirm homogeneous mass. It is also called 3ll and llc and is used as a transplantable malignancy.

| Lewis blood group | <haematology> A pair of blood group activities associated with the A, B, H substances. Lewis Lea is a separate gene, whereas Leb arises from the combined activity of the enzymes specified by Le(a) and H genes. (18 Nov 1997) |
| lewis blood-group system | A group of dominantly and independently inherited antigens associated with the abo blood factors. They are glycolipids present in plasma and secretions that may adhere to the erythrocytes. The phenotype le(b) is the result of the interaction of the le gene le(a) with the genes for the abo blood groups. (12 Dec 1998) |
| Rambourg's chromic acid-phosphotungstic acid stain | <technique> A stain for glycoproteins, used with an electron microscope, with which ultrathin tissue sections reveal complex carbohydrates in the same locations as shown by Rambourg's periodic acid-chromic methenamine-silver stain. (05 Mar 2000) |

| abscisic acid | <biochemistry> A lipid hormone that inhibits cell growth in plants, it is associated with fruit drop, leaf death and seed dormancy. It is synthesised in the plastids from carotenoids. This hormone helps plants deal with water loss, and its effects can be reversed with gibberellins. (06 May 1997) |
| abscisic acid 8'-hydroxylase | <enzyme> Catalyses conversion of abscisic acid to 8'-hydroxyabscisic acid, which rearranges to phaseic acid Registry number: EC 1.14.99.- Synonym: aba 8'-hydroxylase (26 Jun 1999) |
| acetic acid | <chemical> The acid most commonly associated with vinegar, it is the most commercially important organic acid and is used to manufacture a wide range of chemical products, such as plastics and Acetobacter but, except for making vinegar, is usually made through synthetic processes. Derivatives of acetic acid which may be formed by substitution reactions. Mono- and di-substituted, as well as, halogenated compounds have been synthesised. Experimentally, alpha- and n2- substituted acetic acids have been examined for their anti-inflammatory activity and effect on the central nervous system respectively. Additionally, limited exposure data has been collected on dibromo and dichloroacetic acids to determine whether they pose health effects. Synonym: ethanoic acid. (26 Jun 1999) |
| acetoacetic acid | CH3COCH2COOH;one of the ketone bodies, formed in excess and appearing in the urine in starvation or diabetes. Synonym: diacetic acid. (05 Mar 2000) |
