| sweat pore | The surface opening of the duct of a sweat gland. Synonym: porus sudoriferus, porus, pore, skin pore. (05 Mar 2000) |

| sweat test | <investigation> A test used to diagnose cystic fibrosis. Two metal electrodes are placed on the skin of an arm or leg. Very low voltage electricity is used (only a tingling is felt) to measure the concentration of sodium and chloride in the sweat. (19 Jan 1998) |
| duct of sweat glands | The superficial portion of the sweat gland that passes through the corium and epidermis, opening on the surface by the porus sudoriferus or sweat pore. Synonym: ductus sudoriferus, sudoriferous duct, sweat duct. (05 Mar 2000) |
| inotophoretic sweat test | <investigation> A test used to diagnose cystic fibrosis. Two metal electrodes are placed on the skin of an arm or leg. Very low voltage electricity is used (only a tingling is felt) to measure the concentration of sodium and chloride in the sweat. (27 Sep 1997) |
| african green monkey kidney cell | <cell culture> Cells taken from the kidneys of the African green monkey Cercopithecus aethiops sabaeus and used to grow certain viruses like poliovirus. (05 Feb 1998) |
| algae, green | Algae of the division chlorophyta, in which the green pigment of chlorophyll is not masked by other pigments. Classes include charophyceae, bryopsidophyceae, conjugatophyceae, oedogoniophyceae, chlorophyceae, and prasinophyceae. Common genera are acetabularia, chlamydomonas, chlorella, nitella, prototheca, scenedesmus, spirogyra, and volvox. (12 Dec 1998) |
| blue-green algae | The former name for the blue-green bacteria, now classified as Cyanobacteria. A group of prokaryotes. Synonym: Cyanobacteria. (05 May 2002) |
| blue-green bacteria | <organism> Modern term for the blue green algae, prokaryotic cells that use chlorophyll on intracytoplasmic membranes for photosynthesis. The blue green colour is due to the presence of phycobiliproteins. Found as single cells, colonies or simple filaments. In Anabaena, in which the cells are arranged as a filament, heterocysts capable of nitrogen fixation occur at regular intervals. According to the endosymbiont theory Cyanobacteria are the progenitors of chloroplasts. (18 Nov 1997) |

| brilliant green | The sulfate of di-(p-diethylamino)-triphenyl carbinolanhydride. An indicator dye that changes from yellow to green at pH 0.0 to 2.6; also used as a topical antiseptic and as a selective bacteriostatic agent in culture media. Synonym: ethyl green. (05 Mar 2000) |
| brilliant green salt agar | A highly selective culture medium consisting of agar with peptone, lactose, sodium taurocholate, brilliant green, and picric acid solution used in the primary isolation of enteric pathogens such as Salmonella species. (05 Mar 2000) |
| bromcresol green | <chemical> An indicator and reagent. It has been used in serum albumin determinations and as a pH indicator. Pharmacological action: indicators and reagents. Chemical name: Phenol, 4,4'-(3H-2,1-benzoxathiol-3-ylidene)bis(2,6-dibromo-3-methyl-, S,S-dioxide (12 Dec 1998) |
| bromocresol green | Tetrabromo-m-cresolsulfonphthalein;an indicator dye changing from yellow to blue at pH 4.7; used to track DNA in agarose electrophoresis, and in a dye-binding method for analysis of serum albumin. (05 Mar 2000) |
| malachite green | Tetramethyl-di-p-aminotriphenylcarbinol;a dye that has been used as a wound antiseptic, as a treatment of mycotic skin infections, and in biological staining of tissues and bacteria. Origin: G. Malache, a mallow (05 Mar 2000) |
| Paris green | Cupric acetoarsenite, used as an insecticide and as a pigment. (05 Mar 2000) |
