| benzene | <chemistry> A volatile, very inflammable liquid, contained in the naphtha produced by the destructive distillation of coal, from which it is separated by fractional distillation. The name is sometimes applied also to the impure commercial product or benzole, and also, but rarely, to a similar mixed product of petroleum. The Benzene nucleus or Benzene ring, is a closed chain or ring, consisting of six carbon atoms, each with one hydrogen atom attached, regarded as the type from which the aromatic compounds are derived. Structure: C6H6 Origin: From Benzoin. (06 Aug 1998) |

| benzene 1,2-dioxygenase | <enzyme> Converts benzene into cis-benzene glycol; consists of a flavoprotein reductase, reductase(bed), and a ferredoxin, ferredoxin(bed), which transfers electrons from NADH to an iron-sulfur protein, isp(bed), which acts as a dioxygenase Registry number: EC 1.14.12.3 Synonym: benzene hydroxylase (26 Jun 1999) |
| benzene mono-oxygenase | <enzyme> Cytochrome p-450-dependent; forms benzene oxide Registry number: EC 1.13.12.- (26 Jun 1999) |
| benzene nucleus | The six conjugated carbon atoms of the benzene ring. (05 Mar 2000) |
| gamma benzene hexachloride | <chemical> One of the purified isomers of hexachlorobenzene which is used as a scabicide and pediculicide applied topically to the skin in various lotions, creams, and shampoos; gamma benzene hexachloride can be absorbed through the skin. Resembles DDT in its actions but is less persistent. Incorrect name for 1,2,3,4,5,6-hexachlorocyclohexane (lindane). Synonym: hexachlorocyclohexane. Acronym: GBH (05 Mar 2000) |
| 1,4-bis(5-phenyloxazol-2-yl)benzene | A liquid scintillation agent used in radioisotope measurement. (05 Mar 2000) |
| abdominal ring | The opening in the transversalis fascia through which the ductus deferens (or round ligament in the female) and gonadal vessels enter the inguinal canal. Located midway between anterior superior iliac spine and pubic tubercle, it is bounded medially by the lateral umbilical ligament (inferior epigastric vessels) and inferiorly by the inguinal ligament. Indirect inguinal hernias exit the abdominal cavity via the deep inguinal ring Synonym: annulus inguinalis profundus, abdominal ring, annulus abdominalis, internal inguinal ring. (05 Mar 2000) |
| amnion ring | The ring formed by the attachment of the amnion to the umbilical cord at its point of emergence from the umbilicus. (05 Mar 2000) |
| annuloplasty ring | The dilated annulus is sutured, often to a prosthetic ring, thereby reducing it to its normal systolic size. (05 Mar 2000) |
| anterior limiting ring | The periphery of the cornea marking the termination of Descemet's membrane and the anterior border of the trabecular meshwork; an important landmark in gonioscopy. Synonym: Schwalbe's ring. (05 Mar 2000) |
| Balbani ring | An extremely large puff at a band of a polytene chromosome. (05 Mar 2000) |
| Balbiani ring | <cell biology, genetics> The largest puffs seen on the polytene chromosomes of Diptera are called Balbiani rings after the nineteenth century microscopist who first described polytene chromosomes. (18 Nov 1997) |
| Bandl's ring | A constriction located at the junction of the thinned lower uterine segment with the thick retracted upper uterine segment, resulting from obstructed labour; this is one of the classic signs of threatened rupture of the uterus. Synonym: Bandl's ring, Baudelocque's uterine circle, Scanzoni's second os. (05 Mar 2000) |
| Bickel's ring | The broken ring of lymphoid tissue, formed of the lingual, faucial, and pharyngeal tonsils. Synonym: Bickel's ring, tonsillar ring, Waldeyer's throat ring. (05 Mar 2000) |
| Cabot's ring bodies | Ring-shaped or figure-of-eight structures that stain red with Wright's stain, found in red blood cells in severe anaemias, possibly a remnant of the nuclear membrane; a form of basophilic degenerative process. (05 Mar 2000) |
