| copper phosphate cement | A dental preparation, the combination of a solution of orthophosphoric acid with a cement powder (usually zinc oxide) modified with varying proportions of copper oxide. (05 Mar 2000) |
|---|---|
| copper protein | A protein containing one or more copper ions; e.g., cytochrome c oxidase, phenol oxidase. (05 Mar 2000) |
| copper radioisotopes | Unstable isotopes of copper that decay or disintegrate emitting radiation. Cu atoms with atomic weights 58-62, 64, and 66-68 are radioactive copper isotopes. (12 Dec 1998) |
| copper sulfate | <chemical> The pentahydrate sulfate salt of copper. It is a powerful emetic and used orally as an antidote to phosphorus poisoning. Topical application of a 1 per cent solution is used in the treatment of phosphorus burns of the skin. It is also used as a catalyst with iron in the treatment of iron-deficiency anaemia. In 1:1,000,000 concentration it is used to prevent growth of algae in ponds, reservoirs, and swimming pools. Pharmacological action: antidotes, emetics, fungicides, industrial. (12 Dec 1998) |
| copper sulfate method | A method for the determination of specific gravity of blood or plasma in which the blood or plasma is delivered by drops into solutions of copper sulfate graded in specific gravity by increments of 0.004, each of the bottles of solution being within the expected range of the blood or plasma sample; the specific gravity of the copper sulfate solution in which the drop of blood or plasma remains suspended indefinitely indicates the specific gravity of the sample. (05 Mar 2000) |
| copper sulphate | CuSo4-5H2O;it is highly poisonous to algae, is a prompt and active emetic, and is used as an irritant, astringent, and fungicide. Synonym: copper sulfate, copper sulphate. (05 Mar 2000) |
| intrauterine devices, copper | Intrauterine contraceptive devices that depend on the release of metallic copper. (12 Dec 1998) |
| acetyl reduction assay | <investigation> A technique for measuring the nitrogen fixation activity in photosynthetic organisms. It uses a flame ionisation detector and a gas chromatography apparatus to determine the reduction of acetylene to ethylene by the enzyme nitrogenase. (06 May 1997) |
| reduction | <orthopaedics, surgery> The correction of a fracture, dislocation or hernia. (18 Nov 1997) |
| reduction deformity | Congenital absence or attenuation of one or more body parts; usually of the limbs or limb components. (05 Mar 2000) |
| reduction division | The first cell division in meiosis, the process by which germ cells are formed. A unique event in which the chromosome number is reduced from diploid (46 chromosomes) to haploid (23 chromosomes). Also called first meiotic division or first meiosis. (12 Dec 1998) |
| reduction en masse | Reduction of hernial sac and contents, so that intestinal obstruction is still present. (05 Mar 2000) |
| reduction mammaplasty | Plastic surgery of the breast to reduce its size and (frequently) to improve its shape and position. (05 Mar 2000) |
| reduction nucleus | A nucleus that degenerates in the cell during the changes incident to fertilization. (05 Mar 2000) |
| reduction of chromosomes | The process during meiosis whereby one member of each homologous pair of chromosomes is distributed to a sperm or ovum; the diploid set of chromosomes (46 in humans) is thus reduced to the haploid set in each gamete; union of the sperm and ovum then restores the diploid or somatic number in the one-cell zygote.
