| schiff bases | Condensation products of aromatic amines and aldehydes forming azomethines substituted on the n atom, containing the general formula r-n:chr. (12 Dec 1998) |
|---|
| mannich bases | Ketonic amines prepared from the condensation of a ketone with formaldehyde and ammonia or a primary or secondary amine. A mannich base can act as the equivalent of an alpha,beta unsaturated ketone in synthesis or can be reduced to form physiologically active amino alcohols. (12 Dec 1998) |
|---|---|
| histone bases | The alpha-amino acids arginine, histidine, and lysine, which are basic by virtue of the presence in the side chains of a guanidine, imidazole, and amine group, respectively; the term "hexone" is a misnomer since histidine does not have six carbons. (05 Mar 2000) |
| denture bases | The part of a denture that overlies the soft tissue and supports the supplied teeth and is supported in turn by abutment teeth or the residual alveolar ridge. It is usually made of resins or metal or their combination. (12 Dec 1998) |
| ointment bases | Various mixtures of fats, waxes, animal and plant oils and solid and liquid hydrocarbons; vehicles for medicinal substances intended for external application; there are four classes: hydrocarbon base, absorption base, water-removable base and water-soluble base; several are also emollients. (12 Dec 1998) |
| periodic acid Schiff reaction | <technique> A histochemical technique based on periodic acid oxidation of a substance containing the 1,2-glycol grouping. It is used for staining carbohydrates as the resulting dialdehyde reacts with Schiff reagent to form a coloured product. The adjacent hydroxyl groups are oxidized to form aldehydes by periodic acid (HIO4) and these aldehyde groups react with Schiff's reagent (basic fuchsin decolourised by sulphurous acid) to give a purple colour. Acronym: PAS (18 Nov 1997) |
| periodic acid Schiff stain | <technique> A histochemical technique based on periodic acid oxidation of a substance containing the 1,2-glycol grouping. It is used for staining carbohydrates as the resulting dialdehyde reacts with Schiff reagent to form a coloured product. Substances that can be demonstrated include carbohydrates, mucins, cartilage matrix, collagen, reticulum, basement membranes, fibrin, thyroid colloid, amyloid, glomerular hyaline deposits, and a number of other secretions or tissue constituents. Also used in for staining gels on which glycoproteins have been run. See: periodic acid Schiff reaction Synonym: PAS stain. (22 Sep 2002) |
| Schiff base | The reaction of a primary amine with an aldehyde or ketone yields an imine sometimes called a Schiff base. When an arylamine is used the Schiff base may form an intermediate in a staining reaction, for example for polysaccharides. (18 Nov 1997) |
| Schiff, Hugo | <person> German chemist in Florence, 1834-1915. See: Schiff base, Schiff's reagent, Kasten's fluorescent Schiff reagents, periodic acid-Schiff stain, ninhydrin-Schiff stain for proteins. (05 Mar 2000) |
| Schiff, Moritz | <person> German physiologist, 1823-1896. See: Schiff-Sherrington phenomenon. (05 Mar 2000) |
| Schiff-Sherrington phenomenon | When the spinal cord is transected in the midthoracic region or a little lower, the stretch and other postural reflexes of the upper extremity become exaggerated; if the transection is made in the sacral cord, a similar effect is observed in the lower limbs. The effect is regarded as a release phenomenon, i.e., release from an inhibitory influence normally exerted by the spinal segments below the transection. (05 Mar 2000) |
| Schiff's reagent | An aqueous solution of basic fuchsin or pararosaniline which is decolorised by sulfur dioxide, commonly prepared by addition of hydrochloric acid to a dye solution containing a metabisulphite or bisulphite salt; used for aldehydes and in histochemistry to detect polysaccharides, DNA, and proteins. See: Feulgen stain, periodic acid-Schiff stain, ninhydrin-Schiff stain for proteins. (05 Mar 2000) |
| ninhydrin-Schiff stain | <technique> For proteins, proteins are revealed by using ninhydrin or alloxan to produce aldehydes from primary aliphatic amines by oxidative deamination; the aldehydes are shown by reaction with Schiff's reagent. (05 Mar 2000) |
| Kasten's fluorescent Schiff reagents | Fluorescent analogues of Schiff's reagent which are fluorescent basic dyes lacking acidic side groups and containing one or more primary amine groups; used in cytochemical detection of DNA in Kasten's fluorescent Feulgen stain, polysaccharides in Kasten's fluorescent PAS stain, and proteins in the ninhydrin-Schiff stain; such analogues include acriflavine, auramine O, and flavophosphine N.
