| bromodeoxyuridine | <chemical> A nucleoside that substitutes for thymidine in DNA and thus acts as an antimetabolite. It causes breaks in chromosomes and has been proposed as an antiviral and antineoplastic agent. It has been given orphan drug status for use in the treatment of primary brain tumours. Pharmacological action: antimetabolites, antimetabolites, antineoplastic, antiviral agents, radiation-sensitizing agents. Chemical name: Uridine, 5-bromo-2'-deoxy- (12 Dec 1998) |
| bromoderma | An acneform or granulomatous eruption due to hypersensitivity to bromide. Origin: bromide + G. Derma, skin (05 Mar 2000) |
| bromodiphenhydramine hydrochloride | 2-(p-bromo-alpha-phenylbenzyloxy)-N,N-dimethylethylamine hydrochloride;an antihistamine that may cause drowsiness and xerostomia. Synonym: bromazine hydrochloride. (05 Mar 2000) |
| bromoform | <chemistry> A colourless liquid, CHBr3, having an agreeable odour and sweetish taste. It is produced by the simultaneous action of bromine and caustic potash upon wood spirit, alcohol, or acetone, as also by certain other reactions. In composition it is the same as chloroform, with the substitution of bromine for chlorine. It is somewhat similar to chloroform in its effects. Origin: Bromine + formyl.

| bromohyperhidrosis | Excessive secretion of sweat having a fetid odour. Origin: G. Bromos, a stench, + hyper, over, + hidrosis, sweating (05 Mar 2000) |
| bromomethane mono-oxygenase | <enzyme> Enzyme responsible for methane oxidation in vivo Registry number: EC 1.13.12.- (26 Jun 1999) |
| bromophenol blue | <chemical> Alpha,alpha-bis(3,5-dibromo-4-hydroxyphenyl)-alpha-hydroxy-o-toluenesulfonic acid, gamma-sultone. A dye that has been used as an industrial dye, a laboratory indicator, and a biological stain. Pharmacological action: dyes, indicators and reagents. Chemical name: Phenol, 4,4'-(3H-2,1-benzoxathiol-3-ylidene)bis(2,6-dibromo-, S,S-dioxide (12 Dec 1998) |
| bromosuccinimide | <chemical> A brominating agent that replaces hydrogen atoms in benzylic or allylic positions. It is used in the oxidation of secondary alcohols to ketones and in controlled low-energy brominations. Chemical name: 2,5-Pyrrolidinedione, bromo- (12 Dec 1998) |
| bromosulfophthalein | A triphenylmethane derivative excreted by the liver, used in testing hepatic function, particularly of the reticuloendothelial cells. Synonym: bromosulfophthalein, bromsulfophthalein. (05 Mar 2000) |
| bromotrichloromethane | <chemical> A potent liver poison. In rats, bromotrichloromethane produces about three times the degree of liver microsomal lipid peroxidation as does carbon tetrachloride. Chemical name: Methane, bromotrichloro- (12 Dec 1998) |
| bromouracil | <chemical> 5-bromo-2,4(1h,3h)-pyrimidinedione. Brominated derivative of uracil that acts as an antimetabolite, substituting for thymine in DNA. It is used mainly as an experimental mutagen, but its deoxyriboside (bromodeoxyuridine) is used to treat neoplasms. Pharmacological action: antimetabolites, mutagens. Chemical name: 2,4(1H,3H)-Pyrimidinedione, 5-bromo- (12 Dec 1998) |
| bromoviridae | A family of RNA plant viruses with a wide host range in crops and horticultural species. All viruses are readily transmitted by mechanical means and some by insects and pollen. There are four genera: alfamovirus, bromovirus, cucumovirus, and ilarvirus. (12 Dec 1998) |
| bromovirus | A genus of tripartite plant viruses in the family bromoviridae. Transmission is by beetles. (12 Dec 1998) |
| Bromoviruses | <plant biology, virology> Plant viruses with a genome of three linear, positive sense ssRNA molecules. Named originally after brome grass. (13 Nov 1997) |
